Key Facts
  • Total Financing: $901 million
  • Combined BESS Capacity: 473 MWh (236.5 MW)

  • Projects: 3 (Eagle Springs, Lupinus 1, Lupinus 2)
  • Eagle Springs COD: Late 2026
Sunraycer Renewables closed a $901 million project financing facility on May 14, 2026, to fund three Texas solar-plus-storage projects totaling 479.5 MWac of solar capacity paired with 236.5 MWac (473 MWh) of battery energy storage, according to a May 15, 2026 PV Magazine USA report.

The Three Projects

The financed portfolio includes Eagle Springs in Delta County, featuring 77 MWac solar and a 33 MW / 66 MWh BESS. Lupinus 1, located in Franklin County, comprises 161.5 MWac solar and an 82 MW / 164 MWh BESS. Lupinus 2, also in Franklin County, adds 241 MWac solar with a 121.5 MW / 243 MWh BESS. Eagle Springs is scheduled for commercial operations in late 2026, while the Lupinus projects target late 2027 completion.

The Lender Group

The financing facility was provided by a syndicate of banks including MUFG Bank, Ally Bank, Nomura Securities International, Norddeutsche Landesbank Girozentrale (Nord/LB), and Societe Generale, as reported by POWER Magazine on May 14.

Why It Matters

The two-hour duration of the battery energy storage systems (473 MWh against 236.5 MW of inverter power) aligns with ERCOT’s demand profile, where afternoon solar generation transitions to evening peak demand. Sunraycer Renewables also secured revenue-swap agreements with ENGIE earlier in 2026 for this BESS portfolio, establishing revenue floors against ERCOT’s day-ahead and real-time price volatility. This configuration of solar and two-hour batteries aims to address demand-charge reduction and time-of-use arbitrage for large industrial and commercial customers within ERCOT, a market experiencing increased peak demand charges and ancillary services revenue growth driven by data center expansion.

Critical Perspective

Details regarding the tax-equity provider, the Engineering, Procurement, and Construction (EPC) contractor, and the offtaker for these projects were not disclosed in the May 14-15 announcements.
