The deadline for proposals for small turbines of 5-40 kW for a RFP issued through the National Renewable Energy Laboratory (NREL) by the US Department of Energy is September 5. The request for proposals, issued in early June, is for up to five cost-shared sub-contracts to develop "advanced technology" small systems. Individual awards will be up to $1 million, with a minimum cost-sharing of 20% for the design, building and testing. The programme intends to lower the cost of the small turbines, which should be suitable for remote locations by having low maintenance requirements, by being easy to transport and install. They must also meet International Electrotechnical Commission safety standards and meet the specific environmental considerations of some markets.
