From 1995 through 2016, Bradley averaged 385,500 MWh annually at $0.04 per kWh. Bradley provides some of the lowest-cost power in the state. AEA has an RFP out for Bradley Project Operator. Proposals are due April 17th. AEA is working with ADNR and BLM to expedite the transfer of BLM lands to the State. State ownership of lands will have significant lower costs to the utilities and ratepayers. Battle Creek contractor Orion Marine is acquiring permits, proving plans, and mobilizing equipment and camp. Five barge loads will arrive at Bradley in the next month. The camp will be setup by early May and contractor expects to start construction by mid-May. Contractor schedule has diversion taking place in the fall of 2019. WEST FORK UPPER BATTLE CREEK DIVERSION PROJECT By diverting glacial water from the West Fork Upper Battle Creek to Bradley Lake this project will increase Bradley Lake Hydro electricity production approximately 37,300 MWh, or about ten percent. The project includes construction of three miles of road and a concrete diversion dam, and five-foot pipe under the road to convey the water to Bradley Lake. Total Project cost is estimated between $42 and $47 million. In September 2016, The Federal Energy Regulatory Commission amended the Bradley license to add this project. PROJECT OVERVIEW & HISTORY The Bradley Lake Hydroelectric Project is located 27-air miles northeast of Homer on the Kenai Peninsula and has 120 MW of installed capacity. The project consists of a 125-foot high concrete-faced, rock-filled dam structure, three diversion structures, a 3.5-mile long power tunnel and vertical shaft, generating plant, interior substation, 20 miles of transmission line, and substation. The power generation potential of Bradley Lake was first studied by the U.S. Corps of Engineers in 1955. The project was authorized by Congress in 1962. Funding challenges delayed development. AEA, then the Alaska Power Authority, assumed responsibility for the project in 1982. Planning, field work, FERC licensing, construction, the creation of the Bradley Project Management Committee (BPMC), and a Power Sales Agreement between AEA and Railbelt utilities followed. Bradley was declared in commercial operation on Sept. 1, 1991 and has been producing power since. Total project costs, including major capital improvements, as of June 30, 2015 are $328 million. The project was funded through legislative appropriations and AEA revenue bonds that are being repaid by the participating utilities. The BPMC generally manages the project, subject to AEA’s non-delegable rights, duties and responsibilities. Through the Power Sales Agreement, 100 percent of the project’s capacity has been sold to the power purchasers. APRIL 2018
