Rolls-Royce gensets for UK tomato growers

Rolls-Royceà‚ and project developer P3P Partners have signed a contract for the supply of four generating sets. The gensets are destined for two combined heat and power (CHP) plants operated by P3P for British tomato growers APS Salads.

Based on medium speed 12-cylinder Type B35:40 gas engines from Bergen Engines the gensets will be used at 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 5,605 kWe and 6,415 kWth. P3P will feed the electricity into the local grid, while the extracted heat from the exhaust gases and the engine cooling systems will be used to heat 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.

The scope of supply for Rolls-Royce includes the gensets and the exhaust gas systems including the Selective catalytic reduction (SCR) system and heat exchangers as well as electronic systems for controlling engines, generators and supplementary equipment.

Rolls-Royce will deliver the four gensets in November 2015 prior to scheduled commissioning of the CHP plants in January 2016.à‚ Rolls-Royceà‚ and P3P have also concluded a long term service agreement covering approximately 90,000 hours of operation over the 20 years following commissioning.

The combined plant offers efficiency rates of more than 96%, Rolls-Royce says.
