Introduction
How Power and Energy Projects Are Financed
Project finance is how the energy industry gets built. From utility-scale solar farms and offshore wind parks to battery storage systems, hydrogen plants, and data centers — nearly every large-scale energy project reaches construction through some form of structured project financing.
But financing doesn't happen automatically. Lenders, tax equity investors, and institutional capital providers have specific requirements — and they will walk away from deals that don't meet them. Most of the time, the issues that kill deals are not financial problems. They are due diligence problems discovered too late.
This playbook is designed to help developers, sponsors, and their advisors understand what project finance lenders actually look for — and how to get a project finance-ready before approaching investors.
The Project Finance Chain
Every successful energy project financing follows the same basic chain: Site Control → Permits → Contracts → Diligence → Financing. TerraPro Solutions helps developers and lenders address the first link — site control, land rights, and title diligence — before the rest of the chain can hold weight.
Role of Sponsors, Lenders, and Investors
Understanding who sits at the table and what each party cares about is foundational to getting a project financed.
Originates, develops, and often operates the project. Contributes equity (20–40% of cost). Bears development risk.
Provides 60–75% of project cost as non-recourse debt. Underwrites cash flow, contracts, permits, and diligence quality.
US-specific. Banks monetize ITC/PTC tax credits and MACRS depreciation. Covers 30–45% of CapEx in solar and wind.
Long-duration equity for operational assets. Pension funds, sovereign wealth, and infrastructure funds seek stable contracted yields.
DOE LPO, USDA RUS, IFC — provide concessional debt for projects that can't access commercial capital alone.
Utility, corporate, or government buyer of project output. Their creditworthiness determines how much debt the project can carry.
Project Company Structure
Energy projects are almost always structured as a Special Purpose Vehicle (SPV) — a standalone LLC or limited partnership that owns only the project. This isolates risk from the sponsor's balance sheet and creates a clean security package for lenders. The SPV holds all project assets: the land rights, permits, contracts, and equipment. This is why the quality of what's inside the SPV — especially the land title and site control documents — is so critical.
⚡ The Market Reality Right Now
- Deals are moving faster — lenders and tax equity investors are processing more transactions with smaller teams
- Investors have lower risk tolerance — post-COVID, post-inflation, the margin for error on diligence has narrowed significantly
- Developers must show clean diligence early — projects that arrive at financing with unresolved title, access, or site control issues face delays, repricing, or rejection
- Land and title issues are the #1 cause of pre-close delays — not financial modeling, not contracts, not permits
What Lenders Actually Look For
Senior lenders underwrite four things above all else: (1) contracted revenue from a creditworthy offtaker, (2) a complete permit set, (3) a bankable EPC contract, and (4) clean site control with no material title defects. All four must be present. A project that checks three out of four does not get financed — it gets delayed until the fourth is resolved.
PPA, tolling agreement, or capacity contract with an investment-grade counterparty. Without it, there is no debt.
All material permits obtained or on a clear critical path. Regulatory uncertainty kills deal timelines.
Fixed-price, lump-sum with liquidated damages for delay and underperformance. Cost certainty is non-negotiable.
Fee simple ownership or long-term lease with no material title defects, encumbrances, or access issues.
Why Deals Fail: The Land and Title Issues Lenders Find
Most deal delays and closings that fall apart trace back to land and title issues — not financial ones. The following risk areas are the ones lenders and title counsel flag most often in energy project due diligence:
| Risk Area | Why It Kills Deals |
|---|---|
| 🏠 Unclear land ownership | Investors won't fund projects with ownership disputes. Lenders require first-priority security on clean title. |
| 🛤️ Unrecorded easements | Can block access, restrict construction, or create competing claims that invalidate lender's security interest. |
| ⛏️ Mineral rights conflicts | Active or severed mineral rights can invalidate site control, restrict surface use, or create physical risk to the project. |
| 📐 Survey discrepancies | Creates uncertainty around project boundaries, encroachments, and whether the leased/owned area matches the project footprint. |
| 🔗 Assignability issues | Prevents the project company from assigning land rights to lenders as collateral — a basic requirement for any project finance transaction. |
| 🛣️ Access and ingress issues | Without documented, legally enforceable access easements, lenders cannot confirm the project can be built or operated. |
| ⏳ Curative delays | Title defects that surface late in the process require months to cure — causing lender delays, cost overruns, and deal fatigue. |
Most of these issues are not financial problems. They are land and title diligence problems discovered too late.
Where Renewable Energy Deals Break
The following issues are the most common land and title-related causes of project finance delays, repricing, and failed closings in renewable energy projects:
Title Defects HIGH IMPACT
▼Title defects range from minor (an old lien that was never released) to fatal (a gap in the chain of title that means the seller never had ownership to convey). Title insurers will often exclude coverage for known defects — leaving lenders exposed unless defects are cured before closing.
Common Title Defects in Energy Projects
- Gaps in chain of title — missing deeds, unrecorded conveyances
- Deeds from estates without proper probate — voidable transfers
- Unreleased mortgages, judgment liens, or mechanic's liens
- Boundary disputes with adjacent landowners
- Prior recorded solar or wind easements that were never terminated
- Deeds with reverter clauses triggered by energy development
TerraPro Approach
TerraPro Solutions performs comprehensive title searches, curative analysis, and works with title counsel to resolve defects before they become lender exceptions — not after.
Access & Ingress Issues HIGH IMPACT
▼Projects need legally documented access rights to get equipment to site, connect to the grid, and operate over a 25–30 year project life. Access that is informal, permissive, or undocumented will be flagged by lenders and title insurers — and cannot be assigned as collateral.
Access Issues That Kill Deals
- Access road crosses third-party land without a recorded easement
- Verbal permission from a neighboring landowner — not bankable
- Easement that expires before the project's debt tenor
- Access easement that isn't assignable to lenders
- County road that doesn't reach the project boundary
Mineral Rights Conflicts HIGH IMPACT
▼In many states, mineral rights can be severed from surface rights and owned separately. Active oil, gas, or coal extraction rights on a project site can create physical risk to equipment, restrict surface use, and in the most serious cases, give mineral rights owners the ability to physically access the surface — which can invalidate the project's site control.
Mineral Rights Due Diligence
- Confirm whether mineral rights have been severed from the surface estate
- Identify any active mineral leases, drilling permits, or extraction operations
- Review lease terms: can mineral owner access the surface and how?
- Negotiate mineral rights subordination or non-disturbance agreement where needed
- Assess risk by geography — oil and gas states (TX, OK, ND, WY) have highest exposure
Survey Problems MEDIUM IMPACT
▼ALTA surveys are required by virtually every project finance lender. Survey discrepancies — where the physical boundaries don't match the title records, or where encroachments exist — create title exceptions that must be resolved before lenders will close.
Common Survey Issues
- Project footprint extends beyond leased/owned parcels
- Existing structures or improvements encroach onto adjacent land
- Recorded easements don't match their physical locations
- Gaps or overlaps between adjacent parcels in multi-parcel projects
- Wetland or floodplain boundaries not reflected in survey
Curative Delays HIGH IMPACT
▼When title defects are discovered late — during lender due diligence or at the title commitment stage — curing them takes time. Quiet title actions can take 6–18 months. Missing heirs must be located. Lien releases require tracking down creditors. Every week of curative delay costs money and risks deal fatigue from lenders and investors.
Why Early Diligence Saves Deals
TerraPro Solutions recommends completing a full title search and curative analysis before approaching lenders — not during the financing process. Projects that arrive at lender due diligence with a clean title package close faster, at better terms, and with fewer surprises.
Project Finance Readiness Checklist
Before approaching investors or lenders, developers should confirm the following. This checklist represents the minimum threshold for a project to be considered financeable by most institutional lenders.

Part 1: Deal Structures & Project Finance Fundamentals
How Power & Energy Projects Are Financed
Project finance is non-recourse (or limited-recourse) financing where debt is repaid from the project's own cash flows, secured against project assets. Lenders have no (or limited) recourse to the sponsor's balance sheet.
The key distinction from corporate finance: lenders underwrite the project, not the sponsor. This means cash flow predictability, contract quality, and technology risk dominate credit analysis.
Core Metrics Every Lender Underwrites
- DSCR (Debt Service Coverage Ratio) — Annual cash flow available for debt service ÷ total debt service. Minimum 1.20–1.35x depending on sector/risk. P90 DSCR covenants are standard.
- LLCR (Loan Life Coverage Ratio) — NPV of cash flows over loan life ÷ outstanding debt. Typically 1.35–1.50x minimum.
- PLCR (Project Life Coverage Ratio) — NPV of cash flows over project life ÷ outstanding debt. Used for tail risk assessment.
- Gearing / LTV — Debt ÷ total project cost. Typically 60–75% for contracted projects; 50–60% for merchant.
Non-Recourse Senior Secured Debt LOWEST COST
▼The core of project finance. Senior lenders (commercial banks, insurance companies, institutional investors) lend against the project's contracted cash flows with a security package over all project assets, contracts, and accounts.
Key Features
- Non-recourse to sponsor (limited exceptions for completion guarantees)
- Interest rate: SOFR + 150–350bps depending on sector, tenor, and risk
- Tenor: 15–25 years for contracted projects; 7–12 years for merchant
- Requires: fully contracted revenues, independent engineer sign-off, insurance package, debt service reserve account (DSRA)
- All-in cost: typically lowest cost of capital in the capital stack
💡 Key Ratios
DSCR: 1.20–1.35x | Gearing: 60–75% | Tenor: 15–25 years
Tax Equity (ITC / PTC) US-SPECIFIC
▼Large US banks and insurance companies (JPMorgan, BofA, USBank, Berkshire) invest equity to monetize federal tax credits (ITC: 30%+ of project cost; PTC: per-kWh produced) and accelerated depreciation (MACRS). The Inflation Reduction Act (IRA 2022) significantly expanded and extended these credits.
Key Structures
- Partnership Flip: Tax equity receives ~99% of income/losses until target IRR (typically 7–9%), then flips to ~5% interest
- Sale-Leaseback: Developer sells project to tax equity investor, leases back for project life
- Inverted Lease: Developer leases equipment to tax equity investor; investor claims ITC
- Tax equity covers 30–45% of project cost; back-leverage or sponsor equity covers the rest
💡 Key Ratios
Tax Equity IRR: 7–9% | Coverage: 30–45% of CapEx | ITC Adders: Domestic content (+10%), Energy community (+10%), Low-income (+20%)
Construction Finance BRIDGE FINANCING
▼Short-term (12–24 month) credit facility used during construction, converting to term loan at commercial operation date (COD). Construction lenders require EPC wrap (lump-sum, fixed-price), completion guarantee, and adequate contingency.
Key Features
- Floating rate: SOFR + 175–350bps; higher than term loan due to construction risk
- Requires: EPC contract, performance bonds, delay-in-start-up (DSU) insurance, completion guarantee
- Converts to term loan at COD following performance testing and IE sign-off
- Contingency: 5–10% for well-defined projects; 15–25% for first-of-kind technologies
💡 Key Ratios
Tenor: 12–24 months | Cost: SOFR + 175–350bps | Contingency: 5–25%
Mezzanine & Subordinated Debt HIGHER YIELD
▼Junior capital sitting between senior debt and equity. Used to increase leverage beyond senior debt capacity or bridge equity gaps. More expensive than senior debt, less dilutive than equity.
Key Features
- Interest rate: 10–18% cash or PIK; significantly higher than senior debt
- Typically unsecured or second-lien; subordinated to senior debt via intercreditor agreement
- Providers: infrastructure debt funds, private credit, development finance institutions (DFC, IFC)
- Common in: developing market projects, first-of-kind technologies, merchant projects needing equity stretch
💡 Key Ratios
Cost: 10–18% | Tenor: 5–15 years | Use: 5–20% of capital stack
Green Bonds & Sustainability-Linked Bonds CAPITAL MARKETS
▼Debt securities issued in capital markets, ring-fenced for green/sustainable projects. Green bonds provide use-of-proceeds certainty; SLBs link coupon to ESG KPI achievement. Growing pool of ESG-mandated institutional investors drives competitive pricing.
Key Features
- Green bond: ICMA Green Bond Principles compliance required; use of proceeds restricted to green assets
- SLB: coupon step-up if KPIs (GHG reduction, renewable % of power) not met
- Typical tenors: 10–30 years; lower cost than bank debt at scale
- Requires: Second Party Opinion (SPO) from Sustainalytics, Moody's, or MSCI; investment-grade credit rating
💡 Key Ratios
Cost: Treasury + 80–200bps | Minimum size: $200M+ | Rating: BBB- minimum
Government & DFI Programs CONCESSIONAL
▼Federal and multilateral programs provide concessional financing for clean energy projects that cannot access commercial capital on acceptable terms. Essential for first-of-kind and emerging market projects.
Key Programs
- DOE LPO (Title XVII / ATVM): Loan guarantees for innovative clean energy and auto projects; $400B+ authority post-IRA
- USDA RUS: Rural utilities financing; key for rural renewable and grid projects
- US DFC: Development Finance Corporation; OPIC successor; overseas projects
- IFC / World Bank: Multilateral development bank financing for emerging markets
- Export-Import Bank: Financing for projects using US-manufactured equipment
💡 Key Ratios
DOE LPO rate: ~4–5% fixed | DFC: below-market | Process: 18–36 months

Part 2: Solar (Utility-Scale & Distributed)
Sector Overview
Solar PV has become the lowest-cost new generation source globally. Utility-scale projects (>1 MW) are typically financed with tax equity and back-leverage debt, while distributed generation uses PACE, C-PACE, or portfolio financing structures.
Deal Structures
Partnership Flip HIGH RISK
▼The dominant tax equity structure for utility-scale solar. Tax equity investor receives ~99% of income/losses until it reaches its target yield (flip point), then ownership flips typically 5/95. Investor monetizes ITC and accelerated depreciation (MACRS). Requires ~35–40% tax equity as % of project cost.
💵 Typical Deal Size & Timeline
$50M–$500M+ | 18–36 months
Sale-Leaseback MEDIUM RISK
▼Developer sells the project to a tax equity investor who leases it back. Simpler structure than partnership flip, but developer loses ownership during lease term. Popular for smaller or distributed solar portfolios.
💵 Typical Deal Size & Timeline
$10M–$200M | 12–24 months
Inverted Lease (Passthrough Lease) MEDIUM RISK
▼Developer leases equipment to tax equity investor, who then subleases back. Investor claims ITC directly. Common for distributed solar; avoids partnership complexities.
💵 Typical Deal Size & Timeline
$5M–$100M | 12–18 months
Back-Leverage Debt LOW RISK
▼Senior secured debt placed at the sponsor/holdco level, subordinate to tax equity. Allows sponsors to extract value while preserving tax equity structure. Typically 50–65% LTV on sponsor equity value.
💵 Typical Deal Size & Timeline
$20M–$300M | 6–12 months
Key Risks & Mitigation
Irradiance / Energy Yield Risk MEDIUM RISK
▼Actual solar resource below P50 projections. P90 underperformance can trigger DSCR covenant breaches.
Mitigation Approach
Commission independent energy yield assessment (P50/P90/P99). Structure DSCR covenants with P90 cushion. Require performance guarantees from EPC contractor.
Interconnection Queue & Curtailment HIGH RISK
▼Project loses queue position, faces interconnection cost overruns, or grid operator curtails output. CAISO curtailment has exceeded 2 million MWh in peak months.
Mitigation Approach
Obtain binding interconnection agreement before financial close. Model curtailment scenarios in base/downside cases. Negotiate curtailment provisions in PPA.
ITC Recapture Risk HIGH RISK
▼If project is sold, repowered, or ceases qualifying use within 5-year recapture period, IRS claws back a portion of the 30% ITC. Can be 100% in year 1, declining 20% per year.
Mitigation Approach
Structure partnership agreement with recapture indemnity. Obtain tax insurance. Ensure O&M and operational continuity provisions in all agreements.
Module Supply Chain / Manufacturer Risk MEDIUM RISK
▼Module manufacturer bankruptcy or Withhold Release Order (WRO) under Uyghur Forced Labor Prevention Act (UFLPA) blocks module imports.
Mitigation Approach
Require UFLPA compliance documentation and supply chain traceability. Bankability analysis on module OEM. Procure buffer inventory. Consider domestic content adder.
Merchant / PPA Expiry Risk HIGH RISK
▼Project has no long-term offtake, or PPA expires during debt tenor. Merchant solar revenues highly volatile.
Mitigation Approach
Require minimum 10–15 year PPA with investment-grade counterparty for senior debt. Model merchant tail conservatively. Require debt tail of 12+ months beyond PPA expiry.
Degradation Risk LOW RISK
▼Module efficiency declines ~0.4–0.7% per year. Actual degradation exceeding projections reduces revenue over project life.
Mitigation Approach
Use conservative P90 degradation assumptions. Require module manufacturer performance warranties. Factor into energy yield model.
Due Diligence Items
📋 Energy Yield Assessment
▼Tier 1 independent engineer assessment of P50/P90/P99 annual generation. Validate irradiance data source (satellite vs ground-measured). Review soiling, shading, and degradation assumptions.
📋 Module & Inverter Bankability
▼Confirm OEM financial health. Verify product warranties (25-year linear power, 10-year product). Review UFLPA supply chain documentation. Confirm domestic content eligibility if claiming adder.
📋 EPC Contractor Review
▼Verify contractor experience (MW installed, relevant technology). Review EPC contract: lump-sum/fixed-price, liquidated damages for delay and underperformance, wrap provisions. Assess bonding and insurance.
📋 Interconnection & Grid Study
▼Review executed LGIA/SGIA. Confirm no material network upgrade costs remain unresolved. Review transmission congestion study. Confirm Commercial Operation Date (COD) achievability.
📋 Land Title & Easements
▼Full title search on all project parcels. Confirm solar lease/easement terms, decommissioning obligations, and landlord consent to financing. Verify no competing mineral rights extraction risk.
📋 Tax Equity Structure Review
▼Confirm ITC/MACRS eligibility. Review LLCA for flip provisions, deficit restoration obligations (DROs), and exit mechanisms. Obtain tax counsel opinion on structure validity.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- No creditworthy offtake and merchant market too volatile to support debt service
- Interconnection agreement not executed or queue position at risk of termination
- UFLPA violations or supply chain issues that block module delivery
- ITC recapture risk unmitigated and no tax insurance available
- Energy yield P90 does not support 1.20x DSCR at proposed debt sizing
- EPC contractor lacks lump-sum wrap and has insufficient bonding capacity
Key Documents Checklist
Documents Required for Financial Close
- Power Purchase Agreement (PPA)
- Engineering, Procurement & Construction (EPC) Contract
- Long-Term Interconnection Agreement (LGIA/SGIA)
- Solar Land Lease / Easement Agreement
- LLC Agreement (LLCA) / Tax Equity Documents
- O&M Agreement

Part 3: Wind (Onshore & Offshore)
Sector Overview
Wind power is split between onshore projects (typically financed similarly to solar with tax equity and term debt) and offshore wind (far larger, more complex, with specialized marine risk, government offtake contracts, and multilateral financing). The Production Tax Credit (PTC) is the primary federal incentive for wind, though IRA gave projects the choice between ITC and PTC.
Deal Structures
Partnership Flip with PTC / ITC HIGH RISK
▼Tax equity investor receives ~99% of cash and tax benefits (PTC per kWh produced, or ITC) until target yield, then flips. PTC projects require production-based allocation — investors bear production risk. PTC yields are typically lower than ITC given risk profile.
💵 Typical Deal Size & Timeline
$100M–$1B+ | 24–48 months
Back-Leverage Debt (Onshore) MEDIUM RISK
▼Senior secured debt at sponsor holdco level, subordinate to tax equity. Common for onshore wind where sponsor wants liquidity. Typically 50–60% LTV of sponsor equity.
💵 Typical Deal Size & Timeline
$50M–$500M | 9–15 months
OREC / CfD Structure (Offshore) HIGH RISK
▼Offshore Renewable Energy Certificate contracts or Contracts for Difference provide long-term price certainty from state offtake programs (e.g., BOEM/OREC auctions in NJ, NY, MA). Essential for offshore financing given CapEx of $3–6B per project.
💵 Typical Deal Size & Timeline
$1B–$6B+ | 48–84 months
Project Bond / Green Bond (Offshore) MEDIUM RISK
▼Long-dated (20–25 year) institutional bond financing secured by contracted offshore revenues. Insurance companies and pension funds are natural buyers. Requires investment-grade credit profile and long-term contracted cash flows.
💵 Typical Deal Size & Timeline
$500M–$3B | 18–30 months
Key Risks & Mitigation
Wind Resource Risk HIGH RISK
▼Actual wind resource below P50 projection. Offshore wind faces additional complexity from wake effects, extreme weather events, and limited historical data at specific hub heights.
Mitigation Approach
Commission 2+ years of on-site met mast data or calibrated remote sensing (lidar). Require independent energy yield assessment with P90 production. Structure DSCR covenants conservatively.
Turbine OEM Concentration / Bankruptcy Risk HIGH RISK
▼Offshore market has seen Siemens Gamesa and Vestas post large losses. OEM insolvency or refusal to honor warranty/service obligations is existential risk. Onshore market more stable but Siemens Gamesa warranty issues in 2022–24 were significant.
Mitigation Approach
Assess OEM financial health and warranty reserve adequacy. Require long-term service agreements (LTSA) with performance guarantees. Obtain OEM credit support or parent guaranty. Consider turbine supply diversification.
Offshore Construction Risk MEDIUM RISK
▼Vessel availability, weather window constraints, foundation installation complexity, and export cable failures create major cost overrun and delay risk. Cost overruns of 30–50%+ have occurred on multiple US/European offshore projects.
Mitigation Approach
Fixed-price EPC or wrap contract where possible. Construction completion guarantee from sponsors. Adequate contingency (15–20% for offshore). Construction insurance including delay in start-up (DSU) cover.
Offtake / OREC Cancellation HIGH RISK
▼State programs have seen contract cancellations (NJ, MA, CT 2023–24) as developers cited cost inflation exceeding OREC strike prices. No contracted revenue = no financing.
Mitigation Approach
Confirm OREC/CfD contract is fully executed and irrevocable. Model project economics at PPA floor. Assess contract renegotiation provisions. Maintain strong sponsor balance sheet for equity bridge.
Grid Congestion & Curtailment MEDIUM RISK
▼Offshore wind clusters create transmission bottlenecks. Onshore wind in ERCOT, SPP faces high curtailment rates in certain zones.
Mitigation Approach
Review transmission studies and confirm grid upgrade responsibilities. Model curtailment scenarios. Negotiate curtailment sharing provisions in PPA.
Due Diligence Items
📋 Wind Resource & Energy Yield
▼Minimum 1 year on-site data (2+ preferred for offshore). Independent energy yield study at P50/P75/P90. Review wake loss assumptions, availability, and icing loss factors.
📋 Turbine Supply Agreement Review
▼Full review of TSA: delivery schedule, LD provisions, performance guarantees, warranty terms, spare parts obligations. Assess OEM financial statements and warranty reserve.
📋 Foundation & Geotechnical Assessment (Offshore)
▼Review geotechnical survey data. Assess monopile/jacket suitability. Confirm scour protection design. Review export cable route and burial depth.
📋 Permitting & Environmental Compliance
▼Confirm all federal (BOEM, USACE), state, and local permits obtained or on critical path. Review bird/bat mitigation requirements. Confirm NEPA/EIS completion.
📋 Long-Term Service Agreement (LTSA)
▼Review LTSA terms: availability guarantees (typically 95–97%), LD structure, scope exclusions, escalation provisions, OEM right of first refusal on major components.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- OREC/CfD contract not fully executed or subject to unilateral cancellation by state authority
- Wind resource P90 does not support minimum DSCR with reasonable debt sizing
- Turbine OEM in financial distress with no adequate warranty backstop
- No viable interconnection path or grid upgrade cost materially underestimated
- Offshore: no fixed-price construction wrap and sponsor lacks completion guarantee capacity
- Onshore: wake loss assumptions based on manufacturer data only — independent study required
Key Documents Checklist
Documents Required for Financial Close
- Turbine Supply Agreement (TSA)
- Balance of Plant (BOP) / EPC Contract

Part 4: Battery Storage / BESS
Sector Overview
Battery Energy Storage Systems (BESS) are the fastest-growing segment of clean energy infrastructure. Financing ranges from simple balance sheet lending for small systems to complex project finance for standalone 100MW+ systems. Revenue stacking — combining capacity, ancillary services, and energy arbitrage — is standard but creates complex modeling requirements.
Deal Structures
Standalone Project Finance HIGH RISK
▼Non-recourse debt with contracted revenue (tolling agreement, capacity contract, or stacked ISO market revenues). Requires minimum 1.25–1.30x DSCR. Lenders scrutinize technology risk and revenue certainty heavily. Market is still maturing.
💵 Typical Deal Size & Timeline
$50M–$500M | 18–30 months
Co-located Solar+Storage MEDIUM RISK
▼BESS co-located with solar qualifies for ITC on storage portion charged from solar. Simplifies permitting and interconnection. Revenue from solar PPA plus storage capacity/ancillary services. More bankable than standalone BESS.
💵 Typical Deal Size & Timeline
$75M–$750M | 18–36 months
Tolling Agreement Structure MEDIUM RISK
▼Offtaker (utility, load-serving entity) pays fixed capacity payment ($/kW-month) plus variable energy payment. Developer retains dispatch risk. Preferred by lenders as it provides contracted cash flow certainty.
💵 Typical Deal Size & Timeline
$30M–$300M | 12–24 months
C&I / Behind-the-Meter Financing LOW RISK
▼Commercial and industrial customers finance BESS via PACE, operating leases, or energy-as-a-service (EaaS) agreements. Demand charge reduction drives economics. Smaller ticket sizes but large portfolio opportunities.
💵 Typical Deal Size & Timeline
$1M–$20M per site | 3–9 months
Key Risks & Mitigation
Cycle Degradation Risk HIGH RISK
▼Battery capacity degrades with cycling. LFP chemistry degrades ~2–3% per year under normal use; NMC faster. Revenue projections that don't account for degradation will overstate long-term cash flows.
Mitigation Approach
Use independent technical advisor to validate degradation curves. Require manufacturer augmentation provisions in supply agreement. Model degradation in P90 downside case. Require capacity warranties with meaningful LD cover.
Thermal Runaway / Fire Risk HIGH RISK
▼BESS fires (e.g., Arizona 2019, Australia 2021) result in total system loss, insurance claims, permitting setbacks, and project delays. LFP chemistry significantly safer than NMC but not zero-risk.
Mitigation Approach
Require UL 9540A testing compliance. Review fire suppression system design (NFPA 855 compliance). Confirm adequate site spacing and setbacks. Review property and business interruption insurance limits.
Market / Revenue Risk HIGH RISK
▼ISO/RTO market rules change frequently. CAISO, PJM, ERCOT ancillary services markets have repriced materially. Merchant BESS revenue is highly uncertain beyond 3–5 years.
Mitigation Approach
Require minimum 10-year contracted revenue (tolling or capacity) for senior debt. Model ancillary services revenue conservatively. Size debt only to contracted revenue with merchant upside unlevered.
Technology Obsolescence MEDIUM RISK
▼Rapid cost declines and technology improvements may strand existing BESS assets. Replacement cost for augmentation may be unavailable or uneconomical.
Mitigation Approach
Structure augmentation obligations in supply agreement with fixed price or price cap. Include technology upgrade provisions in O&M agreement. Size debt amortization conservatively.
Supply Chain / OEM Risk MEDIUM RISK
▼BESS market dominated by Chinese OEMs (CATL, BYD, CALB). Geopolitical risk, tariffs, and UFLPA exposure create supply chain vulnerability.
Mitigation Approach
Diversify OEM sources where possible. Verify UFLPA compliance documentation. Assess domestic content adder eligibility. Require adequate spare parts inventory.
Due Diligence Items
📋 Independent Technical Assessment
▼Full review of battery chemistry, thermal management system, BMS/EMS software, fire suppression design, and cycle life projections. Validate degradation and augmentation assumptions.
📋 Revenue / Dispatch Modeling
▼Review revenue stack: capacity market, ancillary services (Reg A/D, spinning reserves), energy arbitrage. Assess ISO/RTO market rules and historical pricing. Validate dispatch optimization assumptions.
📋 OEM Financial & Warranty Review
▼Assess manufacturer financial health. Review warranty terms: capacity guarantee, cycle life, warranty period, LD structure. Confirm parent guaranty if OEM is subsidiary.
📋 Insurance Review
▼Confirm property (all-risk), liability, business interruption, and delay-in-start-up coverage. Validate adequacy of limits given fire risk profile. Review NFPA 855 compliance.
📋 Permitting & Safety Compliance
▼Confirm all local fire marshal, building department, and utility interconnection permits. Verify NFPA 855, UL 9540A, and IFC compliance. Review AHJ (Authority Having Jurisdiction) approval.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- No contracted revenue and merchant market projections not supportable at required DSCR
- Fire suppression system not NFPA 855 compliant or AHJ approval not obtainable
- OEM financial distress with no adequate warranty or augmentation backstop
- Degradation assumptions do not account for actual cycling profile — revenue overstated
- ISO/RTO market rule changes eliminate primary revenue source post-financial close
- UFLPA compliance documentation unavailable — delivery blocked at US port of entry
Key Documents Checklist
Documents Required for Financial Close
- Battery Supply Agreement (BSA)
- Engineering, Procurement & Construction (EPC) Contract

Part 5: Hydrogen
Sector Overview
Green hydrogen (electrolysis powered by renewables) is in early commercial-scale development. Project finance for hydrogen is nascent — most deals rely heavily on government support (DOE LPO, H2Hubs, EU Green Deal), offtake commitments, and sponsor balance sheet. Blue hydrogen (SMR with CCS) is more established but faces carbon risk. The IRA's $3/kg clean hydrogen PTC (45V) is transforming project economics.
Deal Structures
DOE Loan Program Office (LPO) HIGH RISK
▼Title XVII and ATVM program loans provide low-cost government debt for first-of-kind clean energy projects. Rate ~4–5% fixed. Required for most early commercial-scale green hydrogen — commercial lenders unwilling to take technology risk alone.
💵 Typical Deal Size & Timeline
$100M–$2B+ | 24–48 months
Offtake-Backed Project Finance HIGH RISK
▼Non-recourse debt backed by long-term hydrogen offtake contract with investment-grade counterparty. Extremely difficult to achieve without 10–15 year fixed-price offtake. Ammonia export projects (e.g., Air Products, Maersk) are best examples.
💵 Typical Deal Size & Timeline
$500M–$5B | 36–60 months
Equity + Grant Stack MEDIUM RISK
▼Early-stage projects funded primarily with sponsor equity + DOE/ARPA-H grants + state incentives. Hydrogen Hub (H2Hub) funding up to $1.25B per hub. 45V PTC ($0.60–$3.00/kg) stackable with grants.
💵 Typical Deal Size & Timeline
$50M–$500M | 18–36 months
Blue Hydrogen / CCS Project Finance MEDIUM RISK
▼Steam methane reforming (SMR) with carbon capture qualifies for 45Q CCS tax credit ($85/ton CO₂) and potentially 45V. More established technology enables traditional project finance, but long-term carbon liability and natural gas price risk remain.
💵 Typical Deal Size & Timeline
$300M–$3B | 30–48 months
Key Risks & Mitigation
Technology Maturity Risk HIGH RISK
▼Electrolyzer technology (PEM, alkaline, SOEC) at commercial scale is relatively unproven. Degradation rates, stack replacement costs, and system efficiency at scale are not well-established.
Mitigation Approach
Require technology at TRL 7+ for project finance. Use proven OEM with commercial references. Obtain independent technical assessment. Stack replacement costs must be explicitly modeled.
Offtake / Market Risk HIGH RISK
▼Hydrogen market is nascent. Pricing, delivery logistics (pipeline, truck, ship), and buyer creditworthiness are all uncertain. No liquid spot market exists.
Mitigation Approach
Require minimum 10-year fixed-price offtake with investment-grade buyer before financial close. Model delivered cost of hydrogen (LCOH) vs alternatives. Confirm storage and transport infrastructure exists.
45V PTC Qualification Risk HIGH RISK
▼IRA's 45V clean hydrogen PTC requires meeting strict lifecycle emissions thresholds and additionality / temporal matching / deliverability (3-pillars) rules for grid-powered electrolysis. Treasury guidance creates significant compliance complexity.
Mitigation Approach
Obtain tax counsel opinion on 45V qualification. Model 3-pillar compliance costs. Consider dedicated renewable PPA to simplify compliance. Obtain tax insurance for 45V.
Water Supply Risk MEDIUM RISK
▼Electrolysis requires large quantities of purified water. Projects in arid regions face water scarcity, permitting challenges, and dewatering costs.
Mitigation Approach
Secure binding water supply agreement before financial close. Confirm water rights in applicable jurisdiction. Review treatment costs. Consider seawater desalination where feasible.
CapEx Overrun Risk HIGH RISK
▼Green hydrogen projects are first-of-kind at commercial scale. EPC contractors have limited experience. Cost estimates highly uncertain.
Mitigation Approach
Require independent cost estimate from Tier 1 firm. Build 20–25% contingency into base case. Obtain lump-sum EPC contract where possible. Require completion guarantee from creditworthy sponsor.
Due Diligence Items
📋 Electrolyzer OEM Assessment
▼Full technical review of stack performance, degradation curve, warranty terms, and OEM financial health. Confirm TRL level and commercial-scale references. Review O&M cost assumptions.
📋 45V / Lifecycle Emissions Analysis
▼Commission independent lifecycle GHG assessment per 45VH2 regulations. Confirm additionality, temporal matching, and deliverability compliance. Obtain tax counsel opinion.
📋 Offtake Agreement Review
▼Confirm buyer creditworthiness, pricing terms, volume commitments, and termination provisions. Assess delivered-to-gate logistics. Review force majeure and change-in-law provisions.
📋 Water Rights & Supply
▼Confirm binding water supply agreement. Review water rights documentation. Assess treatment requirements and cost. Review state water law applicability.
📋 DOE LPO Application Review
▼If DOE financing: confirm conditional commitment terms, credit subsidy cost, technical milestones, and reporting requirements. Review independent cost/technical review findings.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- No creditworthy offtake agreement and no path to one within 24 months
- 45V PTC qualification at risk — lifecycle emissions threshold not achievable without material additional cost
- Electrolyzer technology below TRL 7 or OEM has no commercial-scale references
- Water rights not secured in water-scarce region
- LCOH materially above competing blue hydrogen or alternatives — project uneconomic without subsidy stack
- No viable hydrogen transport/storage solution — pipeline, tube trailer, or ammonia conversion all infeasible

Part 6: Transmission & Grid Infrastructure
Sector Overview
Transmission and grid infrastructure financing includes FERC-regulated interstate transmission (rate-base/cost-of-service), merchant transmission (entrepreneurial lines), and grid modernization (substations, transformers, automation). Equipment lead times — particularly for large power transformers (LPTs) — are 2–4 years and represent critical path risk on virtually every project.
Deal Structures
Regulated (Rate-Base) Financing LOW RISK
▼FERC-regulated transmission earns allowed ROE (~9–11%) on rate base. Financed with investment-grade utility-level debt (A/BBB rated) and equity from utility parent. Most stable transmission financing but limited to FERC-jurisdictional entities.
💵 Typical Deal Size & Timeline
$100M–$5B | 24–60 months
Merchant Transmission / Competitive Upgrade HIGH RISK
▼Merchant transmission earns congestion rents (FTRs/TCCs). Revenue highly uncertain and depends on congestion patterns. Limited project finance market — typically requires substantial sponsor equity. FERC Order 1000 opened competitive transmission development.
💵 Typical Deal Size & Timeline
$50M–$2B | 36–72 months
Infrastructure / Green Bond MEDIUM RISK
▼Long-dated bonds (20–30 year) secured by regulated transmission revenues. Low risk, investment grade. Increasingly issued as green bonds or sustainability-linked bonds given clean energy transmission mandate.
💵 Typical Deal Size & Timeline
$200M–$3B | 12–24 months
Public-Private Partnership (P3) MEDIUM RISK
▼Government entity (state/federal) partners with private developer for grid modernization or resilience projects. FEMA BRIC, DOE Grid Resilience grants (GRIP), and IRA grid funding available. Revenue from availability payments or capacity charges.
💵 Typical Deal Size & Timeline
$50M–$500M | 24–48 months
Key Risks & Mitigation
Equipment Lead Times (LPT/Transformer Risk) HIGH RISK
▼Large power transformers (LPTs) have 2–4 year manufacturing lead times. Substations and switchgear are 18–36 months. Supply chain constraints create critical path and cost escalation risks.
Mitigation Approach
Place transformer orders at project development stage, years before financial close. Include adequate procurement contingency (20%+). Structure EPC agreement around equipment delivery milestones. Consider transformer insurance.
Right-of-Way Acquisition Risk HIGH RISK
▼Securing ROW across multiple landowners for transmission lines is time-consuming and expensive. Eminent domain proceedings can take years. Community opposition to towers/lines is material.
Mitigation Approach
Complete ROW acquisition before financial close. Engage experienced ROW acquisition team early. Assess eminent domain availability and timeline. Budget 20–30% ROW contingency.
FERC & Permitting Risk HIGH RISK
▼Interstate transmission requires FERC approval, state siting permits (often PSC/PUC), and federal NEPA review. Multi-state projects face compounded regulatory risk.
Mitigation Approach
Engage regulatory counsel early. Map all required approvals and timelines. Confirm FERC transmission service agreement is in place. Allow 24–36 months for permitting in base case schedule.
Congestion / FTR Revenue Risk (Merchant) HIGH RISK
▼Merchant transmission revenues dependent on LMP congestion patterns that can change materially as new generation connects or loads shift. FTR values highly volatile.
Mitigation Approach
Model congestion using independent transmission study with multiple scenarios. Do not finance merchant transmission on merchant revenues alone without significant equity cushion. Consider FTR hedge instruments.
Cost Overrun Risk MEDIUM RISK
▼Transmission projects historically experience 20–50% cost overruns due to ROW challenges, environmental conditions, and equipment delays.
Mitigation Approach
Require independent cost estimate. Build 15–25% contingency. Use fixed-price EPC contract where possible. Require sponsor completion guarantee.
Due Diligence Items
📋 FERC Regulatory Review
▼Confirm FERC approval status or timeline. Review transmission service agreement (TSA). Assess rate-making methodology. Confirm no material rate case or prudence review risk.
📋 ROW Title & Acquisition Status
▼Review all ROW documentation (easements, fee simple, licenses). Confirm % of ROW secured at financial close. Assess remaining acquisition risk and timeline. Review condemnation authority.
📋 Equipment Procurement Review
▼Confirm LPT and major equipment orders placed with adequate delivery lead time. Review supply contracts for LDs and delivery guarantees. Assess manufacturer capacity and delivery history.
📋 Independent Transmission Study
▼Commission independent study validating congestion assumptions (merchant), need for the line, and interconnection queue impacts. Review NERC/regional reliability assessment.
📋 Environmental & Permitting Status
▼Confirm NEPA completion (EIS/EA). Review state siting permits. Assess wetlands, cultural resources, and endangered species issues. Confirm all permits on critical path achievable.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- LPT/transformer orders not placed and 2–4 year lead time incompatible with project schedule
- ROW acquisition less than 80% complete at financial close with hostile landowners on critical segments
- FERC approval not obtained or subject to material conditions not yet resolved
- Merchant transmission: congestion revenues insufficient to support debt service under stress scenarios
- State siting permits in multiple jurisdictions with no clear regulatory path for one or more
- Environmental review not complete with potential for injunction from litigation

Part 7: Conventional Power (Gas & Coal)
Sector Overview
Conventional power project finance — natural gas peakers, combined cycle gas turbines (CCGT), and coal — remains active but faces increasing energy transition headwinds. Gas generation plays a critical reliability role in grid operations and is experiencing a renaissance driven by data center load growth. Coal financing has essentially ceased from major institutional lenders.
Deal Structures
Tolling Agreement / Capacity Market HIGH RISK
▼Generator sells capacity ($/MW-day) to grid operator (PJM, MISO, ISO-NE) or via bilateral tolling agreement. Fixed capacity revenue provides debt service certainty. Energy margin (spark spread) is upside. Dominant structure for new gas generation.
💵 Typical Deal Size & Timeline
$200M–$2B | 24–48 months
Traditional Project Finance (CCGT) HIGH RISK
▼Non-recourse senior secured debt (60–70% LTV) backed by long-term PPA, tolling agreement, or capacity + ancillary services revenue. Debt tenors of 15–20 years. DSCR of 1.30–1.50x typical for gas projects.
💵 Typical Deal Size & Timeline
$300M–$3B | 24–42 months
Power Purchase Agreement (PPA) MEDIUM RISK
▼Utility or C&I buyer contracts for all output at fixed price for 10–20 years. Less common for new gas given merchant upside preference. Essential for smaller peakers or combined heat and power (CHP) projects.
💵 Typical Deal Size & Timeline
$50M–$500M | 18–30 months
Sale-Leaseback / Recapitalization LOW RISK
▼Operational gas plants can be refinanced via sale-leaseback or cash-out refinancing. Infrastructure funds and pension investors are buyers of contracted gas generation. Carbon risk increasingly factored into cap rates.
💵 Typical Deal Size & Timeline
$100M–$1B | 12–18 months
Key Risks & Mitigation
Energy Transition / Stranded Asset Risk HIGH RISK
▼Coal plants face accelerated retirement as renewable generation underbids them in energy markets. Gas plants face longer-term transition risk. Carbon pricing risk is material in regulated markets.
Mitigation Approach
Conduct carbon risk scenario analysis. Model accelerated retirement in downside case. Assess capacity market evolution. Coal: institutional financing essentially unavailable from ESG-constrained lenders.
Fuel Supply / Gas Price Risk HIGH RISK
▼Natural gas price volatility directly impacts spark spreads and merchant revenues. Project without a gas supply agreement (GSA) faces full commodity price exposure.
Mitigation Approach
Require long-term GSA with creditworthy gas supplier or pipeline. Model fuel cost in stress scenarios. For tolling structures: confirm toller bears fuel risk. Review basis risk between delivery point and index.
Capacity Market Risk MEDIUM RISK
▼PJM, MISO, ISO-NE capacity market reforms (MOPR, FERC Order 2222) and capacity price volatility create revenue uncertainty. Capacity market earnings are not guaranteed.
Mitigation Approach
Model capacity revenues conservatively using historical auction results. Stress test at -30% to -50% capacity prices. Confirm capacity market position and deliverability requirements.
Environmental Compliance Risk HIGH RISK
▼EPA regulations (Clean Power Plan, Good Neighbor Rule, MATS) impose compliance costs and operational restrictions. State-level carbon pricing adds to cost stack.
Mitigation Approach
Obtain environmental compliance cost estimate from independent consultant. Model carbon cost scenarios. Confirm emissions permits in place. Assess pipeline safety and hazardous waste obligations.
Heat Rate / Efficiency Risk MEDIUM RISK
▼Actual heat rate (BTU/kWh) higher than design specification reduces competitiveness in energy markets. Aging equipment degrades over time.
Mitigation Approach
Require performance testing at COD. Obtain IE verification of heat rate guarantees in EPC. Model degraded heat rate in downside case. Review major maintenance schedule and costs.
Due Diligence Items
📋 Fuel Supply Agreement Review
▼Confirm GSA: term, pricing (fixed vs indexed), delivery point, transportation agreements, and counterparty credit. Assess basis risk. Review fuel storage capacity and backup supply options.
📋 Capacity Market Analysis
▼Review capacity auction results and forward curve. Confirm deliverability status (ICAP qualification). Assess potential market rule changes. Review interconnection agreements.
📋 Environmental Permits & Compliance
▼Confirm all air permits (Title V, BACT, PSD), water permits (NPDES, 316(b)), and solid waste permits. Review NOx/SOx/CO2 compliance strategy. Assess climate litigation risk.
📋 Technical / Equipment Review
▼Independent engineer review of turbine OEM (GE, Siemens, MHI), heat rate performance testing, major maintenance schedule, and remaining useful life. Review OEM LTSA.
📋 Carbon & ESG Risk Assessment
▼Assess institutional investor and lender ESG policies. Model carbon pricing scenarios. Review insurance market appetite. Assess reputational risk for project sponsors.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- Coal project: no institutional lenders available due to ESG policies — effectively unfinanceable
- Gas project: no fuel supply agreement and spot gas price volatility incompatible with debt service
- Capacity market: project not qualified for deliverability or capacity market participation
- Environmental permits not obtained and air permit challenge likely to cause 12+ month delay
- Stranded asset analysis shows negative equity value before end of debt tenor under base case transition scenario
- CCGT: OEM LTSA not executed and major maintenance costs unquantified
Key Documents Checklist

Part 8: Data Centers
Sector Overview
Data center project finance is one of the fastest-growing infrastructure sectors, driven by AI/ML compute demand, cloud adoption, and digital economy growth. Hyperscaler pre-leases (Google, Microsoft, Amazon, Meta) provide the offtake certainty that makes project financing possible. Power delivery — securing sufficient, reliable, and affordable electricity — is the defining challenge for new data center development.
Deal Structures
Hyperscaler Pre-Lease Backed Financing HIGH RISK
▼Master lease or build-to-suit agreement with investment-grade hyperscaler (Microsoft, Google, Amazon, Meta) provides offtake certainty. Senior debt 55–65% LTV at 1.25–1.35x DSCR. Lease terms 10–15 years with renewal options.
💵 Typical Deal Size & Timeline
$200M–$2B per campus | 18–30 months
REIT / Equity Capitalization MEDIUM RISK
▼Data center REITs (Equinix, Digital Realty, Iron Mountain) use combination of equity and investment-grade bonds. Retail and wholesale colocation revenue streams. Lower single-tenant concentration risk than hyperscaler-only.
💵 Typical Deal Size & Timeline
$50M–$1B | 12–24 months
Wholesale Colocation / Multi-Tenant MEDIUM RISK
▼Multiple enterprise or cloud tenants in a single facility. Higher occupancy risk than hyperscaler pre-lease but better diversification. Typical lease terms 3–7 years with extension options. Requires proven operator track record.
💵 Typical Deal Size & Timeline
$50M–$500M | 12–18 months
Green Bond / Sustainability-Linked Bond LOW RISK
▼Large data center operators access capital markets via green bonds tied to renewable energy procurement, PUE targets, and water usage effectiveness (WUE). Investor appetite strong given ESG mandates.
💵 Typical Deal Size & Timeline
$200M–$2B | 6–12 months
Key Risks & Mitigation
Power Availability Risk HIGH RISK
▼Grid capacity constraints limit data center development in key markets (Northern Virginia, Silicon Valley, Dublin, Singapore). Utility queue times of 3–7 years are common. Without power certainty, no project.
Mitigation Approach
Secure executed power delivery agreement or utility interconnection agreement before financial close. Confirm utility capacity and timeline. Consider on-site generation (gas backup, solar+BESS). Model power cost escalation.
Hyperscaler Concentration Risk HIGH RISK
▼Single tenant representing >70–80% of revenues creates existential lease non-renewal risk. Hyperscaler lease termination without notice provisions is project-killer.
Mitigation Approach
Require minimum 10-year initial term with renewal options. Obtain parent guaranty from hyperscaler operating entity. Model non-renewal in downside case. Require 12+ month notice of non-renewal.
Power Cost Escalation MEDIUM RISK
▼Data centers are highly power-intensive (PUE 1.2–1.5x). Rising energy costs — particularly in markets with carbon pricing or renewable mandates — compress margins.
Mitigation Approach
Lock in long-term PPAs for renewable power. Review power cost structure: utility rate ($/kWh) vs. fixed capacity charge. Model power cost inflation at 3–5% per year. Consider on-site generation.
Cooling / Water Risk MEDIUM RISK
▼High-density AI compute requires advanced cooling (liquid cooling, immersion cooling). Water-intensive cooling raises environmental permitting and supply concerns in water-scarce markets.
Mitigation Approach
Review cooling system design for AI workload density requirements. Confirm water supply agreement (if applicable). Assess PUE relative to market standard. Confirm local regulatory acceptance of cooling water discharge.
Technology / Obsolescence Risk MEDIUM RISK
▼GPU/server technology changes rapidly. Facility built for current rack densities (10–20 kW/rack) may be insufficient for future AI workloads (100–200 kW/rack). Hyperscalers increasingly demand customization.
Mitigation Approach
Design for upgradability: modular power and cooling infrastructure. Confirm power density specifications meet hyperscaler requirements. Include upgrade provisions in lease. Review structural load capacity.
Permitting / Community Opposition MEDIUM RISK
▼Large data centers face opposition over power consumption, water use, noise (cooling fans), and tax incentive concerns. Zoning and building permits in constrained markets are challenging.
Mitigation Approach
Engage community early. Confirm zoning allows data center use. Review tax incentive agreements (abatements often require jobs/investment commitments). Obtain all permits before financial close.
Due Diligence Items
📋 Power Delivery Review
▼Confirm utility service agreement / LGIA is executed. Review power capacity, reliability (N+1 minimum), and delivery timeline. Assess backup generation (diesel UPS, on-site gas). Model total power cost including utility charges and PPA.
📋 Tenant / Lease Review
▼Full review of hyperscaler or colocation lease: term, renewal options, termination rights, rent escalation, buildout specifications, and operating covenants. Confirm parent guaranty. Review assignment provisions for financing.
📋 Technical Infrastructure Review
▼Independent review of cooling system (PUE target), power distribution (UPS, PDU), fiber connectivity (carrier diversity), and physical security. Confirm compliance with Uptime Institute Tier III/IV requirements if applicable.
📋 Renewable Energy / ESG Compliance
▼Review PPA structure for renewable power. Confirm RECs or additionality approach. Assess tenant ESG requirements. Review alignment with GHG Protocol Scope 2 reporting.
📋 Market & Competitive Analysis
▼Assess market vacancy, absorption rates, and hyperscaler demand pipeline. Review competing supply. Confirm campus location in Tier 1 market with adequate fiber, power, and labor.
⚠️ Fatal Flaws & Walk-Away Triggers
Walk Away If Any of These Exist:
- No executed power delivery agreement and utility queue time makes COD unachievable within financing window
- Single hyperscaler tenant >80% of revenue with no minimum term or parent guaranty
- Power density specifications (kW/rack) inadequate for AI workloads specified by hyperscaler
- Cooling system not designed for required rack densities — facility effectively unusable for intended purpose
- Tax incentive agreement requires job/investment commitments that project cannot meet
- Fiber connectivity: no carrier-diverse, low-latency connectivity available at site — disqualifying for hyperscaler

Conclusion
Principles for Successful Power & Energy Project Finance
The fundamentals of project finance never change — even as technologies, markets, and regulations evolve.
"The best project finance deals are the ones where every risk has an owner, every contract has a backstop, and every assumption has been stress-tested. The fatal flaws are always the ones nobody bothered to check."
The Five Principles
No deal closes without complete, bankable contracts. Offtake, EPC, and interconnection are the three non-negotiables.
P90 energy yield. -30% revenue. +25% CapEx. If the project survives, it's worth financing.
Identify project-killers before committing capital. Walk away early — it's always cheaper than walking away late.
Investment-grade offtakers, proven EPC contractors, and experienced operators are worth paying for.
Aggressive leverage destroys projects. 1.30x+ DSCR with P90 cushion keeps you out of default court.
