10 Due Diligence Mistakes That Destroy Project Value

What if the risk that kills your deal is already in your documents?

Due diligence isn’t about checking boxes. It’s about protecting value.

Top Due Diligence Mistakes in Power Projects

When “Good Enough” Due Diligence Isn’t Enough

Due diligence is the first real stress test for any power project.
It’s where assumptions about land, ownership, access, and control either hold up or collapse under scrutiny.

When due diligence is rushed or delayed, small oversights turn into structural risk, often discovered after capital is committed and timelines are locked.

This article breaks down the most common due diligence mistakes in power and energy development and how to avoid land risks that derail projects and deals.

The Top 10 Due Diligence Mistakes (At a Glance)

#MistakeWhy It Creates RiskHow to Prevent It
1Assuming site control is enforceableUnenforceable agreements fail financing and saleLegal enforceability review
2Ignoring assignabilityDeals collapse at exitAlign site control with exit
3Treating access as informalNo legal access, no projectConfirm recorded access

10Checklist-only diligenceNuance is missedRisk-based analysis

These risks apply to any power project that depends on land, capital, and an exit.

1. Assuming Site Control Is Enforceable

The mistake:
Developers sign leases or options without confirming whether they are legally enforceable under state law.

Why it matters:
An unenforceable agreement cannot support financing, tax equity, or an M&A transaction.

Prevention strategy:
Have site control reviewed for enforceability, not just completeness.

“If site control isn’t enforceable, it isn’t control. It’s just paper.”

2. Ignoring Assignability Language

The mistake:
Agreements restrict assignment or require landowner consent that may never come.

Why it matters:
A project that can’t be assigned can’t be sold.

Prevention strategy:
Confirm assignment rights align with your exit strategy from day one.

Real-world example:
Projects stall in late-stage M&A when buyers discover assignment restrictions that were never flagged.

3. Treating Access as “Good Enough”

The mistake:
Relying on informal paths, historic use, or handshake access.

Why it matters:
Without legal, recorded access, construction and operation can be blocked.

Prevention strategy:
Confirm access is documented, perpetual, and enforceable.

4. Waiting Too Long to Review Title

The mistake:
Title review is delayed until financing or sale.

Why it matters:
Fatal flaws discovered late are expensive and sometimes unfixable.

Prevention strategy:
Start title review during early-stage development, not after momentum builds.

5. Overlooking Mineral and Subsurface Rights

The mistake:
Assuming surface control includes subsurface rights.

Why it matters:
Mineral owners can disrupt construction or demand compensation.

Prevention strategy:
Analyze mineral estates and severances early.

“Surface rights don’t stop a drilling rig.”

6. Missing Ownership Chain Breaks

The mistake:
Incomplete ownership histories are overlooked.

Why it matters:
Chain breaks create title defects that delay closing.

Prevention strategy:
Require a full ownership chain review, not just the last conveyance.

7. Relying on Assumptions Instead of Documents

The mistake:
Assuming prior developers handled the details.

Why it matters:
Assumptions collapse under lender and buyer scrutiny.

Prevention strategy:
Verify everything through recorded documents and legal review.

8. Skipping Curative Planning

The mistake:
Identifying issues without planning how to fix them.

Why it matters:
Curative work takes time, sometimes years.

Prevention strategy:
Create a curative roadmap alongside risk identification.

9. Ignoring Local Land-Use History

The mistake:
Failing to investigate prior uses, shared corridors, or legacy agreements.

Why it matters:
Historic rights can limit development even if they’re not obvious.

Prevention strategy:
Research historical land use and unrecorded rights.

10. Treating Due Diligence Like a Checklist

The mistake:
Checking boxes instead of analyzing risk.

Why it matters:
Checklists don’t capture nuance or deal-specific risk.

Prevention strategy:
Use a risk-based approach tailored to project stage and exit strategy.

What Developers Need to Know

Most land acquisition risks aren’t surprises. They’re oversights.

The difference between a smooth closing and a stalled project often comes down to when diligence starts and how deeply it’s done. Early, strategic due diligence protects timelines, valuations, and investor confidence.

If you uncover risks early, you can fix them. If you uncover them late, they define the deal.
