The Tennessee Valley Authority, created in 1933 under former president Franklin Roosevelt's New Deal, is requesting proposals through Jan. 16 for the supply of up to 2,000 megawatts of "dispatchable" capacity and "as-available" energy from biomass and other renewable sources.

"Dispatchable" energy capacity can be scheduled by the TVA for delivery ahead of time, either by the hour or day. "As available" energy is intermittent, such as wind, solar and hydro power.

The TVA requires that proposers are capable of sustaining a guaranteed minimum run time of eight consecutive hours per day. It wants 1,000 megawatts of power generation–half dispatchable and half as-available–by June 1, 1,500 megawatts of generation by June 1, 2010, and the full 2,000 megawatts of power generation by June 1, 2011.

Biomass, landfill gas, combined heat and power, solar, wind, ocean, tidal, geothermal and other types of renewable or clean energy sources are eligible. Power must be deliverable to either the TVA transmission system or the distribution system of a TVA power distributor.

The TVA is requiring proposers to provide certain financial information so creditworthiness can be established. To view the TVA's request for proposal, visit
