Britain’s Food and Environment Research Agency (Fera) in North Yorkshire is the host to a new, 230 kW CHP unit, operating under a 10-year discount energy purchase contract, from ENER-G. The company financed, installed, and now operates the CHP system at no cost to Fera and contracts the energy produced back to the customer at a discounted rate.
The CHP system is driven by a diesel engine converted to use natural gas; this engine then drives an alternator that generates the site’s electricity requirements. The unit also contains three heat exchangers that capture heat from the water jacket, lube oil and exhaust gases to ensure maximum energy efficiency.
The scheme delivers a range of benefits, says ENER-G, including: zero capital outlay or risk; no ongoing maintenance or aftercare costs; guaranteed capped energy costs for the length of the agreement; and fast implementation of the scheme. Financial savings should amount to some £26,000 per year.
