Two food industry CHP projects for Centrax

UK-based Centrax Gas Turbines has won two new CHP contracts for applications within the food processing industry in Britain and Ireland. The company is to install a 5 MWe CHP plant to supply heat and power to GlaxoSmithKline’s factory in Coleford, Gloucestershire, where Ribena and Lucozade energy drinks are manufactured, and a similar plant at the Lakeland Dairies Co-op in Co. Cavan, Ireland. In both cases, the company will supply plant based on the Rolls-Royce 501K gas turbine, which Centrax packages into a CHP generator set.

For the former, the first UK CHP project won by the company for six years, Centrax will also supply a waste heat recovery boiler, gas compressor, black start diesel generator and a control system. GSK needs the CHP plant to support implementation of a new bottling and preform manufacturing operation at the site. In Ireland, the new CHP scheme will be located in a new building next to the existing boilerhouse. Centrax has supplied several plants to Lakeland previously.

The contracts were announced during an open day at Centrax’s manufacturing facility in Devon, UK, which was arranged to showcase extended facilities at the site built following the company becoming the European packager of the Rolls-Royce Trent gas turbine. At 64 MW, this is a much larger machine than the 501 range.

Over several years working with the smaller Rolls-Royce gas turbine, Centrax has installed CHP plants in 25 countries, with the bulk going to France, the Netherlands, UK, Spain and Italy. Recently, and while the market for industrial-scale for CHP plants in Europe has been slow, the company has moved further afield; installing units in Pakistan, Russia, Bulgaria, Tunisia and India.

Now, the company is assembling four larger, Trent-based plants for a mid-merit power-only plant in France, and has won a contract to supply two more units to Hungary. The very high electrical efficiency of the units (64%) makes them ideal for mid-merit use – where the plant is typically used for a few hours each day – says Centrax.

The new UK CHP project at GlaxoSmithKline does not necessarily signal a return to busier days for industrial-scale CHP companies in Britain, said Guy West, Director of the Centrax Gas Turbine Division. While recent UK government announcements on support measures for CHP were welcome, particularly an extension of exemption from the Climate Change Levy, they are not enough, on their own, to re-start the business, said West.
