The combined heating and power (CHP) installation comprises of 2 No 1 400 kW[e] natural gas fired CHP engines type JMS420GSN as manufactured by Jenbacher and were installed in 2005 and have been fully operational since that time. The CHP plant has been maintained in accordance with the manufacturers requirements with the correct level of service/overhaul being carried out at the key milestone (hours run) stages. All records are available for review including past performance reports. (It should be noted that during the major overhaul at 60 000 hours, the crankshafts for both engines were inspected and were deemed to be of a condition that did not require them to be replaced at that time).
