The proposals selected are J-Power USA Development’s Shoreham generation site and the Chaithness Long Island II’s Yahank site, reported power-eng.com.

The company said the new plants will also allow it to repower National Grid’s 388MW Port Jefferson natural gas and oil-fired steam plant.

LIPA authorized its staff to begin negotiating potential power purchase agreements (PPA) for new generating resources consistent with the company’s Electric Resource Energy Plan.

LIPA chairman Howard Steinberg said, "The action today to support the addition of new, clean and more efficient natural gas, base-load generation, coupled with an aggressive renewable energy program and continued support for our $924 million 10-year energy efficiency program, positions LIPA to diversify its energy portfolio and begin the transition to a cleaner, more reliable, and reasonably priced electric system on Long Island."
