BKI completed an interconnection study for the Riverbend Landfill methane gas generation plant owned by Waste Management in McMinnville, OR. The study was based on an initial plant size of 3.28 MW with a rating of 4.1 MVA at 0.8 power factor. Maximum future peak generation was assumed to be 8.2 MW. System upgrades and operational policy modifications were recommended to optimize integration of the generation source.

Yelm Hydro is a run-of-the-river hydroelectric project on the Nisqually River. The plant contains three generators, nominally rated at 3MW, 3MW, and 6MW respectively. BKI’s scope of work consisted of multiple projects over several years. One phase included the upgrade of all controls and protection at the hydro plant, including the protection coordination with BPA. Another included the BPA metering and monitoring. A third consisted of developing as-built documents for the entire station. There were also multiple additional projects such as safety controls at the spillways, providing an alternate source of station service, etc.
