Seminole Electric seeks PSC approval to build new gas plant, shut down coal plant," by POLITICO Florida's Bruce Ritchie: Seminole Electric Cooperative Inc. is seeking approval from the Public Service Commission to build a new natural gas plant and shut down an existing coal-fired plant near Palatka. Seminole Electric is a Tampa-based wholesale electricity provider to nine rural cooperatives providing service to 1.6 million people in 42 counties. In a Dec. 21 determination-of-need petition filed with the PSC, Seminole Electric says it is losing power purchase agreements by 2021 that will create the need for 901 megawatts of power. The new gas-fired generating plant, proposed at the Seminole Generating Station near Palatka, will provide 1,050 megawatts of power and is expected to be completed on Dec. 1, 2022, according to the petition. The plant will cost $727 million, a Seminole Cooperative spokesman said Tuesday.
