TWACS demand-response units are expected to allow Rushmore’s member utilities to shed load by controlling equipment such as air conditioning units, and hot water heaters during periods of peak demand. This will allow Rushmore’s member utilities to balance demand throughout the day, keeping the capital costs associated with the generation system under control.

Vic Simmons, general manager of Rushmore, said: “As member-owned cooperatives, we are keenly aware of the need to manage the costs associated with purchasing and generating electricity for our members. Demand response is a key driver for cooperatives as it offers customer service options, while at the same time controlling the costs that all members pay.”

Up to 28,000 meter end points and 10,000 demand-response units are expected to be deployed. The five member utilities that will deploy TWACS technology are West River, West Central, Cherry-Todd, Butte, and Moreau-Grand Electric Cooperatives.
