Union Power Partners, a subsidiary of Entegra Power Group, awarded Emerson Process Management a contract to replace turbine controls at Union Power Station. The plant, located in southern Arkansas, is one of the largest combined-cycle facilities in the U.S. with a generating capacity of 2,200 MW and comprises four individual 2x1 combined-cycle power blocks. Emerson will replace legacy controls on the power block's GE Frame 7FA gas turbines and GE D11 steam turbine with Ovation' control technology, and the GE EX2000 systems with its Ovation generator excitation technology. The contract also calls for Emerson to supply auto synchronizers. Equipment delivery will take place in October, and the first retrofitted power block is expected to be back online in December 2014.
