Arizona Public Service Co. seeks proposals for distributed energy resources, including hydropower technologies. A pre-bid conference is scheduled Sept. 5; proposals are due Oct. 17.
APS said it needs distributed energy resources �- generators located at or near customers �- to meet part of its overall resource needs and to fulfill the regulatory requirements of Arizona’s Renewable Energy Standard.
The standard requires that by 2025, 15 percent of the energy APS provides to customers must come from renewable energy sources. It includes a provision that 30 percent of the renewable energy must come from distributed sources.
APS previously issued a call for proposals for renewables, including hydropower. (HNN 6/6/08) That solicitation closed Aug. 13, with final selections to be made Nov. 21.
APS said it wants up to 200,000 MWh per year through its current request for proposals, although it could choose to procure more or less depending on the quality of proposals. The minimum annual energy output per project must be at least 1,500 MWh per year, APS said.
Delivery must begin no earlier than Jan. 1, 2009, and no later than Dec. 31, 2013. Priority will be given to projects that are reasonably expected to begin delivering electricity by Dec. 31, 2010, APS said. Contract terms will be a minimum of five years and a maximum of 30 years.
Eligible technologies include hydro, roof-top solar electric systems, small windmills, biogas, biomass, geothermal, hybrid wind, and natural gas.
APS, part of Pinnacle West Capital Corp., serves about 1.1 million customers in 11 of Arizona’s 15 counties.
Non-binding notices of intent to bid are due Sept. 22, followed by the Oct. 17 deadline for proposals. A short list of companies is to be notified Jan. 16, 2009, and final selections are to be made May 12, 2009, APS said.
