Hull Street Energy to Acquire Two Peaking Plants in PJM, Expanding Milepost Power Portfolio
Bethesda, MD and Houston, TX, March 23, 2026 – Hull Street Energy, LLC (“HSE”) has agreed to acquire two power plants from Rockland Capital, LP (“Rockland”): Lee County Generating Station, a 677 MW natural gas turbine facility in Illinois, and Tait Electric Generating Station, a 586 MW dual-fuel facility in Ohio.
The Lee and Tait facilities are strategically located to provide capacity and operational flexibility in the constrained PJM electricity market, where tightening supply-demand dynamics are increasing the need for reliable, fast-start resources that support grid stability.
The transaction is expected to close later this year, subject to regulatory approvals. Once the acquisition is finalized, HSE will own nearly 5,000 MW of highly efficient, reliable gas-fired and dual-fueled generation capacity operating within the Milepost Power fleet, making it one of the nation’s largest, privately held power producers.
Troutman Pepper Locke acted as legal counsel to HSE. PEI Global Partners, LLC and Houlihan Lokey acted as financial advisors, and Bracewell acted as legal counsel to Rockland.
