The
Encyclopedia of Oklahoma History and Culture credits Henry Holderman, a member of the Cherokee tribe, as first envisioning Grand River as a source for hydroelectric power for the
Cherokee Nation. Even prior to Oklahoma statehood in 1907, Holderman began building political support for such a project. A feasibility study by the
Army Corps of Engineers attracted favorable attention in the Oklahoma legislature, leading to creation of the Grand River Dam Authority (GRDA), a state agency, in 1935. Construction began in 1938 on the
Pensacola Dam on the
Grand River (
lower Neosho River) as a
Works Progress Administration project. The dam was completed in March 1940, creating the lake behind it. Between 1941 and 1946, the U.S. government took control of Pensacola Dam to divert power to the war effort. Control was returned to the GRDA by the Congress and President Truman amid local celebration in August 1946. The powerhouse has four hydroelectric turbines, providing a total capacity of 114,000 kW. GRDA states that an average year can provide 211 million kWh. The
Salina Pumped Storage Project constructed for GRDA during 1968 - 1971, created
Lake W. R. Holway. It was designed to produce 260 MW of power during peak consumption periods. During periods of lower power demand, water is pumped from Lake Hudson to Lake Holway and released back down through the pump-generators during periods of high energy demand. In the late 1970s, the Authority decided to build the GRDA Coal-fired Power Generation Complex, located near
Chouteau, Oklahoma. Now more than four decades old, the two units need extensive retrofits to meet new emission regulations and to improve energy efficiency with more modern technologies. In 2008, GRDA,
Oklahoma Gas & Electric (OG&E) and
Oklahoma Municipal Power Authority (OMPA) jointly purchased the Redbud Generation facility near
Luther, Oklahoma for 434.5 million. The facility uses natural-gas fueled turbines to generate electricity. Rated capacity was 1230 MW. GRDA owns 36 percent of the venture, while OG&E owns 51 percent and is designated as the operator. OMPA owns the balance. In 2010, GRDA completed a new visitors' center adjacent to Pensacola Dam. The building was designed to be the home of GRDA Ecosystems Management offices, a state-of-the-art water research lab, offices for the Grand Lake Area Chamber of Commerce, a community auditorium and historical exhibits. On June 13, 2012, GRDA approved becoming a member of the Large Public Power Council (LPPC). The LPPC consists of the largest publicly owned not-for-profit, electric utilities in the U.S. LPPC’s priorities include tax and finance issues, interaction with the Federal Energy Regulatory Commission, energy and environmental policies.
Proposed privatization Governor
Mary Fallin (R) issued an executive order in July 2013 to establish a 15-member task force that would research the possibility of dismantling GRDA and selling its assets. The members chosen by the governor have “experience or interest in energy issues.” It would include two members of her “Bold Ideas” task force. Governor Fallin announced on August 13, 2013, that she was suspending the task force and its work indefinitely. She said that she still supported the mission of the task force, she realized that the timing was bad and that the review could undermine GRDA's efforts to sell revenue bonds.
Canadian Hills wind farm GRDA has a financial interest in a wind turbine "farm" near
El Reno, Oklahoma developed by Apex Wind Energy Holdings LLC and Atlantic Power Corp. Known as the Canadian Hills wind farm, it will sell power to GRDA, the Oklahoma Municipal Power Authority and Southwestern Electric Power Co., a Louisiana-based unit of
American Electric Power. The facility initially had 135 turbines and a design output of 300 megawatts of electric power. Google, Inc. contracted with GRDA to buy up to 48 megawatts of this power for its data center in
Pryor, Oklahoma.
Natural gas fired generation facility On January 14, 2014, the GRDA Board of Directors approved purchase and installation of gas turbine generators to be installed at the GRDA Coal-Fired Complex in
Chouteau. The new unit, which is known as Unit 3, is estimated to cost US$372 million, is designed to produce 495 megawatts (MW) of electric power. The turbine-generators alone will cost US$77.84 million. Mitsubishi Power Systems is supplying M501J gas turbines and SRT-50 steam turbines for the new unit. Concurrently, the Authority renamed the Chouteau complex as the Grand River Energy Center. The new
combined cycle generation process is energy-efficient because natural gas fuels a gas turbine that directly generates power. Then the hot turbine exhaust gas is cooled by boiling water to generate more steam, which drives a steam-powered generator and generates more electric power. The new generation unit was expected to be put in service in 2017, ==Organization==
