E-MAIL: click here to contact the contracting officer via, ruth_adams@nrel.gov. Under this Supplemental Announcement, DOE is soliciting Applications to develop and validate co-firing technology using a "closed-loop" feedstock supply. Respondents are encouraged to form appropriate consortia or other business arrangements with the agricultural community, industry, power producers, or other applicable organizations for the conduct of this venture. These arrangements are intended to demonstrate how cooperative efforts can lead to sustaining, economically beneficial, biomass power generation. "Closed-loop" refers to operations that specifically plant, grow, harvest, use, and regrow, at the same production site, any biomass fuel or feedstock in a sustainable, permanent manner that is in whole or in part used for an energy application. "Biomass", for the purpose of this Supplemental Announcement, means organic matter derived through the process of photosynthesis. "Co- firing", for the purpose of this Supplemental Announcement, refers to the combustion of biomass and coal, excluding lignite, for power production. Successful Applicants should demonstrate an approach to the integration and successful application of a "closed-loop" feedstock supply system and a technically viable co-firing boiler system for power production. The overall objective of selected projects is to successfully demonstrate the viability of co-firing "closed-loop" agricultural biomass as a supplemental fuel for power production. To meet this objective, successful applicants will: 1) determine the optimum parameters for low-cost, high-performance co-firing of "closed-loop" biomass fuels with coal of natural gas for power production through pilot-scale biomass co-firing tests; and 2) validate the operational viability of co-firing biomass with coal through a full-scale demonstration. Awards under this Supplemental Announcement will be Cooperative Agreements with a term of up to two years. Subject to funding availability, the total DOE funding available under this Supplemental Announcement will be approximately $1,500,000. DOE anticipates selecting one application for award under this Supplemental Announcement. A minimum cost share of 50% of total project costs is required in order to be considered for award under this Supplemental Announcement. Solicitation Number DE-PS36-99GO10383, in conjunction with this Supplemental Announcement 13, will include complete information on the program including technical aspects, funding, application preparation instructions, application evaluation criteria, and other factors that will be considered when selecting projects for funding. Issuance of the solicitation is planned for July 6, 1999, with responses due 30 days following solicitation release. The solicitation, once issued can be obtained from the Golden Field Office Home Page at http://www.eren.doe.gov/golden/solicitations.html. All responsible sources may submit an application and all timely applications will be considered. Posted 06/29/99 (W-SN348277). (0180)
