What Caithness Energy does
Caithness Energy, L.L.C. is a privately-held Independent Power Producer (IPP) that develops, acquires, operates, and manages renewable energy and natural gas-fired power generation projects, primarily in the northeastern United States. The company's most prominent asset was the Caithness Long Island Energy Center, a 350-365 MW natural gas-fired combined cycle generation facility located in Suffolk County, New York, which began commercial operations in 2009 and was described in the company's materials as one of the most efficient combined cycle plants in NYISO. The facility supplied baseload electricity to Long Island under wholesale power arrangements with utilities, grid operators, and ratepayers. Beyond the flagship plant, Caithness historically held PJM-region baseload assets that were divested to Talen Energy in 2025.
The business model is generation-and-sale: Caithness owns and operates fuel-fired generation capacity and monetizes output through wholesale electricity sales into organized markets (NYISO/PJM) and via contractual arrangements with utilities and load-serving entities. Revenue mechanics depend on capacity factors, spark spreads, and capacity market revenue, all of which are cyclical and not publicly disclosed. Distribution is direct-to-grid rather than through traditional retail channels, and no pricing model, contract terms, or per-MWh rates are publicly available.
In 2026, Caithness divested the Caithness Long Island Energy Center to Lotus Infrastructure Partners (renamed Brookhaven Energy Center), removing its largest revenue-generating asset. The firm is structured as an LLC, operates with a very small headcount of 1-10, and is led by Chairman and CEO James D. Bishop. Headquartered in Red Bank, New Jersey, Caithness continues to operate as an independent power producer with remaining, undisclosed projects following the recent divestiture cycle.

Caithness Energy competitors and assessment
Company assessmentDirect peers
- Calpine Corporation: Largest US independent power producer with a predominantly natural gas-fired combined cycle fleet. Directly comparable IPP business model, generation technology, and PJM/Northeast market overlap to Caithness Energy.
- Talen Energy Corporation: PJM-focused IPP that acquired Caithness's PJM baseload assets in 2025. Operates a comparable mix of natural gas and other generation serving PJM markets, with overlapping customer base and contracting structures.
- Competitive Power Ventures (CPV): Private US IPP developing, owning, and operating natural gas-fired and renewable generation projects, with strong presence in PJM and the Northeast. Closely comparable private IPP business model, scale, and project-development focus to Caithness.
- LS Power: Private power generation and energy infrastructure developer with a portfolio of natural gas and renewable assets across multiple US markets. Same private IPP + project development playbook as Caithness, with overlapping generation mix and US focus.
- Lotus Infrastructure Partners: Infrastructure investor that acquired the Caithness Long Island Energy Center in Jan 2026 and renamed it Brookhaven Energy Center. Operates/owns mid-market power and energy infrastructure assets on comparable terms, making it a directly comparable infrastructure IPP-and-asset-owner peer.
Broad incumbents
- Vistra Corp: One of the largest competitive power generators in the US, with a multi-fuel portfolio spanning natural gas, coal, nuclear, and growing renewables/solar/storage. Comparable IPP business model at much larger scale, operating in overlapping NYISO/PJM markets.
- NRG Energy: Major US competitive power generator with a large natural gas and renewables portfolio serving PJM, ERCOT, and other markets. Overlapping IPP model and overlapping customer segments with Caithness, though NRG's scale and retail focus make it a broader incumbent rather than a direct niche competitor.
- NextEra Energy Resources: World's largest generator of wind and solar energy and a leading developer of battery storage, while also operating natural gas and other conventional assets. Comparable IPP development/ownership model in NYISO/PJM and broadly aligned with the renewable+gas dual-fuel thesis of Caithness.
- JERA Co., Inc. Japan's largest power generation company with growing US generation and renewables investments. Operates comparable thermal and renewable IPP assets and has overlapping LNG/fuel-supply integration with Caithness's natural gas focus, though at far larger global scale.
Others
- Macquarie Asset Management: Global infrastructure investor active across US power and energy transition assets. Comparable as an investor in IPP-scale generation assets (a buyer-side analog to strategic acquirers like Lotus/Talen engaging with Caithness), rather than a direct operating competitor.
