Doral's $900M Cold Creek Deal: A Blueprint for Building Big Solar in Texas
Doral Renewables secures $900M for a groundbreaking solar-plus-storage project in Texas—here's why it matters for the future of energy.
A $900 million financing close for a single solar-plus-storage project doesn't happen by accident. It requires the right site, the right market, and — increasingly — the right financial architecture. Doral Renewables just demonstrated all three.
The Philadelphia-based independent power producer announced the financial close of its Cold Creek Solar + Storage project in Schleicher and Tom Green Counties, Texas, making it the company's largest construction financing outside of its 1.3 GW Mammoth Solar complex in Indiana. For anyone tracking renewable energy financing or battery storage investment in the ERCOT market, this deal is worth studying closely — not just for its size, but for how it was put together.
The Project: What Cold Creek Actually Represents
At 430 MWac of solar capacity paired with 340 MWh of battery storage, Cold Creek is substantial but not unprecedented for Texas. What makes it noteworthy is the combination: a solar-plus-storage facility of this scale, structured with a Notice to Proceed issued this month and a commercial operation target of summer 2028.
To put the generation capacity in human terms, the project is forecasted to power approximately 66,000 homes. That's roughly the residential load of a mid-sized Texas city. But the real significance isn't the headline number — it's that Cold Creek represents Doral's deliberate bet on ERCOT as a long-term growth market, not just an opportunistic play.
Texas already hosts more utility-scale solar than any other state, and Cold Creek is being built precisely because demand on the ERCOT grid is accelerating faster than most analysts projected two years ago. Industrial load growth, data center expansion, and population influx have all tightened the supply picture in ways that make a 430 MW solar-plus-storage asset genuinely valuable rather than speculative.
How the Financing Was Structured — and Why It Matters
The $900 million package is where this deal gets interesting for developers watching the market. MUFG led the syndicate as Lead Arranger, with Santander, HSBC, Ally, and IDB participating. The debt stack breaks down as follows:
- $400+ million in construction-to-term financing
- $35 million in tax equity bridge loans
- ~$55 million in letters of credit
- $360 million in Production Tax Credits monetized through a 10-year tax credit transfer agreement with an investment-grade corporate buyer
That last piece is the one to pay attention to. The PTC transfer structure — enabled by provisions in the Inflation Reduction Act — allows Doral to sell its tax credits directly to a corporate buyer rather than navigating a traditional tax equity partnership. The result is $360 million in upfront capital from a cleaner, faster transaction. Marathon Capital advised Doral on the PTC transfer; White & Case and Stonehenge Capital represented the buyer.
This is the new blueprint for utility-scale project finance: stack construction debt, bridge the tax equity, then monetize the PTCs through a transfer to a creditworthy corporate counterparty. It's more efficient than the old tax equity model, and the fact that Doral executed it at this scale signals that the market for PTC transfers is maturing quickly.
For other developers eyeing Texas solar-storage projects, the Cold Creek deal establishes a replicable framework. You don't need a single massive institutional tax equity partner. You need relationships, investment-grade offtakers for the credits, and a lender syndicate willing to underwrite the construction risk.
What This Does for the Texas Grid
Schleicher and Tom Green Counties sit in west-central Texas — prime solar country, with high irradiance and relatively flat terrain. The grid interconnection dynamics in that part of ERCOT have been challenging in recent years due to congestion, but pairing 340 MWh of storage with 430 MW of solar generation partially addresses the dispatch problem. Storage lets the project shift generation into higher-value hours rather than dumping power onto a congested grid during peak solar production.
That's not a trivial distinction. Storage-paired solar projects in ERCOT command better economics than standalone solar because they can capture the notorious "duck curve" price spreads — the gap between midday lows and evening peak prices. In Texas, those spreads can be extreme. The state's deregulated market, with real-time prices that occasionally spike to $5,000/MWh, rewards flexibility in ways that regulated markets simply don't.
Cold Creek's 340 MWh of storage isn't just a reliability add-on — it's a revenue optimization tool in one of the most volatile electricity markets in the world.
Production Tax Credits: The Invisible Engine Behind the Deal
It's impossible to discuss renewable energy financing at this scale without acknowledging how central federal tax incentives are to project viability. The $360 million in PTCs Doral monetized over 10 years isn't incidental — it likely represents the difference between a project that pencils and one that doesn't.
The Production Tax Credit pays project owners based on actual electricity generated, creating an ongoing revenue stream rather than a one-time benefit. For a 430 MWac solar facility in Texas, 10 years of PTC revenue at current rates represents substantial cash flow that directly supports debt service. By transferring those credits to a corporate buyer, Doral converts future tax credit value into present-day capital — essentially securitizing the federal incentive.
This is sophisticated project finance, and it reflects how the IRA's transferability provisions have unlocked deals that might have stalled under the old tax equity regime. The caveat, of course, is that this all depends on the political durability of those incentives. Energy tax credit legislation remains an active front in Washington — a fact that makes Doral's 10-year transfer agreement look like smart risk management as much as financial optimization.
What Comes Next in Texas
Doral has signaled clearly that Cold Creek is the foundation of a broader Texas strategy, not a one-off. CFO Evan Speece described it as "a cornerstone for our future work across the Lone Star State." Given that Doral is simultaneously managing Mammoth Solar — a 1.3 GW complex that, when complete, will be among the largest solar farms in the country — the company's execution capability is increasingly hard to question.
The broader picture for Texas solar-storage investment remains compelling. ERCOT has interconnection queues measured in hundreds of gigawatts, though the queue itself is a bottleneck: not every project that enters will be built. What separates the projects that close financing from the ones that languish is exactly what Cold Creek demonstrated — a viable off-take structure, a disciplined capital stack, and creditworthy counterparties at every link in the chain.
The developers who will win in Texas over the next five years aren't necessarily the ones with the biggest pipelines. They're the ones who have figured out how to get from shovel-ready to financial close in a market where lender appetite is strong but execution risk is real. Cold Creek is evidence that Doral has that figured out. Watch for the company's next ERCOT announcement — it probably won't be long.
