Clifton 1 is a Westinghouse 501 combustion turbine that began commercial operation in 1974. After operating for more than 50 years, it’s reached the end of its useful life. Sunflower plans to replace Clifton 1 with new gas-fired combustion turbines. The combined capacity of the new turbines will fully utilize the existing 97.6 MW of interconnection service granted to Sunflower by Southwest Power Pool (SPP) at the point where Clifton Station interconnects to the grid.
