Basin Electric Power Cooperative said Dec. 18 that it is making progress as the year draws to a close on its Pioneer Generation Station and Lonesome Creek Station projects, which will help meet member cooperatives’ still-rising electrical needs in the Williston Basin.
Phase III construction is progressing at Pioneer Generation Station, a natural gas-based peaking station northwest of Williston, N.D. All 12 Wärtsilä 20V34SG reciprocating engines have been delivered to the site, and 220 workers are currently working on administration areas, installing piping and exhaust ducts, assembling switchgear, installing conduit and pulling electrical cable. Phase III construction at the plant began in May 2015 and is scheduled to be complete in June 2016.
Phase III at Pioneer totals 112 MW of additional capacity, on top of the three 45-MW combustion turbines brought on-line at the plant in the 2013-2014 period.
At Lonesome Creek Station, a natural gas-based peaking station located west of Watford City, N.D., Units 4 and 5 turbines and generators are on site as part of a Phase III expansion. Switchyard construction will be completed by the end of 2015 and ready for service by Feb. 1, 2016, and commissioning of the combustion turbine generators will begin in February 2016.
Josh Rossow, Basin Electric project manager III, said that Phase III mechanical work is about 88% complete and electrical work is about halfway finished at Lonesome Creek Station. Phase III construction began in May 2015 and the project is on track for commercial operation by April 1, 2016.
Lonesome Creek already has three 45-MW gas turbines, with Phase III covering two additional 45-MW turbines.
