In May, Rolls-Royce and P3P Partners signed a contract for the supply of four electricity generating sets. The gensets are based on medium speed 12-cylinder Type B35:40 gas engines from Bergen Engines and are destined for two combined heat and power (CHP) plants operated by P3P for British tomato growers APS Salads.
Four gensets will go into service in two energy centres on behalf of the APS Salads greenhouses on the Isle of Wight in the south of England where APS Salads grows tomatoes for domestic supermarkets.Each of the gas-powered gensets will produce 5,605kW of electrical power and 6,415kW of heat. P3P will feed the generated electricity into the local grid, while the extracted heat from the exhaust gases and the engine cooling systems will be used to heat up the greenhouses. After cleaning the engine exhaust gases, they will be injected into the greenhouses to increase the CO2 content in order to promote plant growth. Rolls-Royce had already supplied two generator sets to energy system provider P3P in 2013.
