Southwest Electric Cooperative is part of a 3-tiered system of electric cooperatives that generate, transmit and distribute electricity to the rural residents and businesses of the state.
- Electricity is generated by Associated Electric Cooperative based in Springfield, Missouri.
- That power is transmitted from AECI's generation facilities to substations by six transmission cooperatives. Two of these transmission cooperatives, KAMO Power Electric Cooperative, located in Vinita, Oklahoma and Sho-Me Power Electric Cooperative, located in Marshfield, Missouri, own and maintain the substations serving SWEC's system.
- The electricity is then distributed from the substations to homes, farms and businesses by 40 distribution cooperatives throughout Missouri. Southwest Electric Cooperative is a distribution cooperative.
