Koillis-Satakunnan Sähkö Oy is a company focused on the sale of electricity and the provision of electricity-related services. Like a typical local, medium-sized electricity company, Koillis-Satakunta Sähkö both manages and maintains the electricity distribution networks in its area and produces and sells electricity to its customers. The company owns hydroelectric power plants in Killinkoski, Soininkoski and Käenkoski, as well as in Ylivieska, Nivala and Kaustinen. Despite its own electricity production, most of the electricity sold by the company is purchased on the NordPool electricity exchange.

The electricity network operated by North-Eastern Satakunta Electricity is located in the area where South Ostrobothnia, Central Finland and Pirkanmaa meet.
