Calpine acquired the Granite Ridge Energy Center from Granite Ridge Holdings for $500 million, subject to working capital adjustments. The 745-MW, combined-cycle, gas-fired power plant is located in Londonderry, New Hampshire. The power plant, which commenced commercial operation in 2003, features two Siemens 501G combustion turbines, two heat recovery steam generators and one steam turbine. Calpine expects the transaction to close by the first quarter of 2016.

GE received an order from the Tennessee Valley Authority (TVA) to supply two high-efficiency 7HA.02 gas turbine generators for the new combined-cycle Allen plant. The new plant will replace three coal-fired units that are being retired as TVA works toward a December 2018 deadline from the U.S. Environmental Protection Agency (EPA) to reduce coal emissions. The TVA Allen plant will have the capacity to generate 1,000 MW of power in combined-cycle mode, the equivalent power that would be needed to supply 1 million U.S. homes.

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.

Siemens received an order for the turnkey construction of the Bandirma II combined-cycle (gas and steam) power plant (CCPP) in Turkey. The purchaser is Enerjisa, a joint venture of Sabanci Holding and E.ON. Upon completion in the spring of 2016, this plant will have an installed capacity of around 600 MW and an efficiency of over 60 percent.
