Groton
Location: SD
Operator: Basin Electric Power Coop
Configuration: 1 X 95 MW LMS100 gas turbine
Operation: 2006
Fuel: natural gas, oil
T/G supplier: GE, Brush
Quick facts: This is the launch unit of the LMS100 machine which uses a combination of aeroderivative and frame features and has an intercooler. Construction stared in Aug 2005 and first firing was in Apr 2006. The $69mn plant uses gas from the Great Plains Synfuels Plant in Beulah, ND, delivered by a 12mi tap from the Northern Border Pipeline. It is electrically connected to a nearby WAPA substation. The machine has a very low simple-cycle heat rate of 7,500 btu/kWh and can be synchronized at full load in 10min fro a cold start. A second machine was added in 2008.
