6 July 2006 - GE Energy yesterday announced that its first LMS100 simple-cycle gas turbine had gone into commercial operation at Basin Electric Power Cooperative's Groton Generation Station located near Groton, South Dakota, USA.
GE said that the LMS100 had successfully completed commissioning requirements of a 12-minute start capability to full power, synchronous condenser operation, demonstration of guaranteed output, heat rate and emission levels. In addition to its contractual requirements, the LMS100 had also demonstrated the ability to achieve full power from a cold metal start within 10 minutes.
Plant construction began at the Basin Electric site in August 2005 with delivery of the gas turbine generator set in November 2005. First fire was achieved in April 2006 with full-load operation in May. The LMS100 has accumulated 138 hours of operation and 48 starts to-date.
Basin Electric's LMS100 unit is fuelled by natural gas from the Northern Border Pipeline and is connected to the existing substation operated by the Western Area Power Administration. It will be operated for summer and winter peaking. Electricity will be transmitted to rural electrical systems, which transmit power to cooperatives in northeast South Dakota.
GE Energy's LMS100 provides a combination of proven frame and aeroderivative gas turbine technologies. It delivers 100 MW with thermal efficiency from 44 to 50 per cent. The LMS100 reduces CO2 emissions by more than 30 000 tons when compared to a typical simple-cycle 100 MW gas turbine plant over the course of an average 2184 hour peaking season.
