In utility-scale power and energy project development, timelines are tight, capital is impatient, and risk tolerance is low. In this environment, due diligence isn't a box to check โ it's the foundation of project success.
Whether you're originating a site, preparing it for financing, or evaluating an acquisition, understanding when and how to evaluate key areas of risk is essential. This framework outlines five core pillars of due diligence, each with its own purpose, timeline, and strategic value.
The Five Pillars at a Glance
Pillar 1: Land & Title Due Diligence
Purpose: Validate legal control of the project footprint and ensure long-term development viability.
- Conduct a fatal flaw analysis to identify site-level red flags: environmental constraints, incompatible land use, or physical barriers
- Order and review title commitments, focusing on Schedule BII for exceptions and encumbrances
- Initiate curative work to resolve ownership discrepancies, outdated instruments, and missing interests
- Confirm legal access for all parcels; identify and record necessary easements
- Align ALTA survey boundaries with title and landowner agreements
- Ensure site control documents are valid, assignable, and fully executed
Pillar 2: Technical Due Diligence
Purpose: Validate design assumptions and asset quality; ensure the project is technically sound.
- Review engineering design packages and ensure compliance with current codes and standards
- Validate equipment certifications, warranties, and performance histories
- Cross-reference layout and design files with real-world site conditions
- Conduct site inspections and compile condition reports
- Use drone imagery or 360ยฐ visuals to confirm siting accuracy and identify potential obstacles
- Document and track outstanding discrepancies requiring remediation
Pillar 3: Financial & Transaction Due Diligence
Purpose: Support valuation, investment decision-making, and capital stack alignment.
- Analyze offtake agreements (e.g., PPAs) for duration, pricing structure, and creditworthiness
- Assess tax equity eligibility and confirm compliance with ITC/PTC structuring requirements
- Review lease payment schedules, escalation clauses, and landowner obligations
- Verify title endorsements, estoppel certificates, and third-party consents
- Compare current budget to actuals and adjust for any underreported risk
- Align transaction documentation with intended exit strategy and timelines
"Sophisticated developers don't treat due diligence as a formality โ they treat it as an integrated, sequenced process that guides decisions, reveals opportunities, and reduces uncertainty."
Pillar 4: Permitting & Regulatory Due Diligence
Purpose: Ensure all entitlements and authorizations are identified, trackable, and on schedule.
- Confirm site zoning allows for intended use; flag rezoning or CUP requirements
- Track status of environmental permits and identify overlapping jurisdictional reviews
- Document health protection zone requirements and setback constraints
- Engage local stakeholders early to mitigate opposition or delays
- Compile required tribal, FAA, or SHPO notices where applicable
Pillar 5: Interconnection Due Diligence
Purpose: Understand grid access feasibility, cost exposure, and timing risk.
- Confirm queue position, study phase, and projected upgrade requirements
- Review interconnection agreement terms and milestones
- Assess cost allocation risk and the potential for shared or shifted expenses
- Analyze curtailment risk, deliverability constraints, and historic congestion data
- Engage utility contacts and review typical response timelines
- Flag any long-lead equipment procurement tied to interconnection scope
Align Process with Purpose
By aligning your due diligence efforts with these five pillars โ and timing each to your project stage โ you give yourself more leverage, fewer surprises, and a far better shot at long-term success.
The developers who move fastest through financing and M&A aren't cutting corners on diligence. They're doing it earlier, more systematically, and with the right partners in place from the start.
