500 MW Gas Plant Built for Reliability
TVA will build and operate an approximately 500 megawatt (MW) dual-fuel, simple-cycle combustion turbine (CT) facility called the New Caledonia Gas Plant to serve its seven-state service territory. TVA says the CTs are needed to provide dispatchable generation capacity to meet year-round generation and maximum capacity demands and to support continued load growth consistent with the 2019 Integrated Resource Plan.
Helps Integrate Solar and Renewables
The New Caledonia CT units are intended to enhance the TVA fleet's flexibility so the system can better integrate distributed resources and renewable generation such as solar. TVA states the CTs support growing amounts of solar in its generation portfolio by providing dispatchable capacity when solar is not producing.
Supports TVA Goal of Low Power Rates
TVA says the CT units are needed in part to comply with a primary objective under the TVA Act that power be sold at rates "as low as feasible." TVA indicates the new units will help meet planning reserve margin targets and support selling power at low feasible rates for its service territory.
