What Rockland Capital does
Rockland Capital, LLC is a private equity firm founded in 2003 that specializes in control investments in power generation assets across the United States and the United Kingdom. The firm targets under-managed, undervalued, distressed, or later-stage development assets in the power sector and optimizes them through active operational management, restructuring, and commercial repositioning. Its portfolio spans natural gas-fired combined cycle plants, simple cycle peaking facilities, cogeneration assets, and renewable energy (solar, wind, biomass, biogas) along with battery and flywheel storage, with operations concentrated in PJM, ERCOT, MISO, and UK markets.
Rockland raises and manages a series of closed-end private equity funds (Rockland Power Partners I through V) with cumulative commitments of approximately $3.1 billion. The firm's most recent fund, Rockland Power Partners V, closed at its $1.2 billion hard cap in November 2025 in under eight months — a more than 70% increase over the predecessor fund. Fund V explicitly targets dispatchable power generation and, for the first time, a meaningful allocation to greenfield development of new plants to serve data center and AI-driven load growth.
The firm generates revenue through standard PE fund management economics — management fees on committed or invested capital across its fund vintages, plus carried interest on realized investment returns above specified LP thresholds. Specific fee terms are not publicly disclosed. Rockland operates from a single headquarters in The Woodlands, Texas, with a senior, lean team (11-50 employees) led by Co-Managing Partners Scott Harlan (founder) and Jim Maiz. The firm has completed 30+ realized transactions since inception and maintains wholly owned operating subsidiaries including Whitetower Energy Limited (UK), Platte River Biogas, LLC, Redback Power, LLC, and Rockland Renewable Ventures, LLC.
