For years, land and title issues were the leading causes of failed renewable deals. Not anymore.
Today, interconnection risk is the #1 deal breaker in renewable energy M&A. Projects that look bankable on paper are collapsing under the weight of clogged queues, ballooning costs, and slipping CODs.
The result? Developers lose control of timelines, investors lose confidence in valuations, and buyers walk away.
The backlog is bigger — and slower — than most realize:
2,600 GW of projects are stuck in U.S. queues — more than double current installed capacity. Zero Emission Grid – Interconnection Backlog, 2025
Solar projects alone make up roughly 1,080 GW of the U.S. interconnection backlog — by far the largest share of any resource. EnergyScape Renewables, 2025
Only about 14% of solar projects that enter the queue ever get built.
Median wait times have stretched to 5 years; in CAISO, the average is 9.2 years. Lawrence Berkeley National Lab – U.S. Interconnection Queues
Interconnection costs are surging — in PJM, they’ve tripled since 2019, topping $200/kW.
Up to 90% of queued projects drop out before reaching operation.
This isn’t a paperwork problem — it’s a systemic choke point reshaping the market.
Queue Reform Fallout
New FERC rules (Order 2023) are designed to speed up the process, but the transition has reset timelines and forced less-mature projects to the back.
Transmission Bottlenecks
Even approved projects can’t move forward without upgrades. Grid capacity is the new land rush.
Valuation Uncertainty
Investors can’t rely on revenue models when COD slips by years, undermining confidence and deal pricing.
Contract Breakdowns
Site control and PPA terms often don’t align with today’s extended interconnection timelines, triggering renegotiations or deal collapse.
Developers – Site control agreements expiring mid-queue.
Investors – Valuations cut when CODs move years back.
Landowners – Property tied up longer with uncertain outcomes.
Buyers – Queue position now determines whether a deal closes or craters.
Interconnection risk isn’t going away — but you can mitigate it:
Make Queue Position a Due Diligence Item – Treat it like title or permitting.
Align Land Agreements to Reality – Build in flexibility for 5–7 year CODs.
Evaluate Alternative Markets – Emerging zones may offer faster timelines.
Run Risk Assessments Early – Don’t wait until closing to uncover grid constraints.
Engage Specialists – From site control to curative and interconnection, expertise pays off.
Interconnection isn’t just slowing projects — it’s breaking deals. CODs are slipping, valuations are shifting, and contracts are collapsing under the strain of the queue.
If you’re not putting interconnection at the center of your due diligence, you’re leaving your deal exposed to the #1 risk in renewable development.
