An integrated non-fossil fuel electrical power system

The authors describe an integrated nonfossil-fuel electrical power system (NFFPS) developed on a farm at Loughborough, England. They investigates the performance and economic viability of the system, both for electrical energy consumption on the farm and for export to the national electricity grid for supply to other consumers. The performance of the system was monitored over a one-year period, to take account of climatic variations during the different seasons. Results obtained are discussed, together with the economics of the system and the development of control strategies to optimize the profit/energy ratio. The NFFPS described uses well-proven items of plant. No significant teething problems were encountered, and, of the 60 MWh of energy produced annually, almost 80% is exported to the national grid.
