Load Management

Marathon Water HeaterLoad management, or demand response, refers to the control of various electric loads during times of peak demand on the electric system. By managing loads from grain bin fans, irrigation pivots, air conditioners, and water heaters so they are not all on at the same time, Northern Electric Cooperative is able to reduce wholesale power purchases and save money and resources for the cooperative.

The load management system of Northern Electric's wholesale power supplier, East River Electric Power Cooperative, has been operating since 1985 and has saved electric cooperative members more than $188 million in avoided wholesale power costs. More than 70,000 different electric loads in homes, farms, and businesses of member consumers throughout eastern South Dakota and western Minnesota are connected to the system. These loads include electric water heaters, air conditioners, grain bin fans, irrigation systems, and large industrial processes. Northern Electric members willing to put electric loads under load management are eligible for special rebates and electric rates.

Control is initiated monthly through a highly sophisticated system that communicates with control receivers connected to the various loads. East River operates the system on behalf of its member systems to moderate wholesale power costs, improve system efficiencies, and provide member-consumers with energy options.

East River Electric has designated certain time periods during certain months when load management will not be utilized. These time periods are called demand-waiver periods. The link below provides the times and dates of the demand-waiver periods.

Please contact a member services representative at 605-225-0310 for more information on the load management program, or to enroll in the program.
