Energy Investors Funds, a private equity fund concentrating on North American power deals, has sold its Glen Park Hydroelectric Project to Fort Chicago Energy Partners for $80 million.

The New York based plant was co-owned by Energy Investors Funds’ US Power Funds I and II vehicles and its sale was classified as a “planned liquidation” by EIF partner Mark Segel.

Segel worked on the deal along with EIF senior vice president Mark Voccola.

Fort Chicago is among a growing number of PE investors concentrating on the energy space at a crucial time in the industry’s history. Already, the Canadian PE firm have invested in Alliance Pipeline and the Alberta Ethane Gathering System, both in Canada, and in Aux Sable, an extraction facility in Illinois.

Calls seeking comment were not acknowledged by press time.

Yesterday, CCMP Capital Advisors invested $345 million in Chaparral Energy Inc.

Earlier this month, Consol Energy acquired a Dominion Resources asset. Last year, Lime Rock Capital Partners invested $25 million in Expert Petroleum and the private equity firm also invested $11 million in Pangeo Subsea along with CCTV Investments and the investment arm of Chevron. Lime Rock also backstopped Allis-Chalmers when the Texan oilfield services company sold shares to pay down debt.

Now, entire funds are looking to capitalize on the space. Tenaska Capital Management assembled a fund last year with the assistance of placement agents from Greenhill & Co. and NGP Energy Technology Partners closed a second fund at $348 million.
