Power Supply

Delivering a diverse, flexible power supply is WPPI Energy’s core purpose.

Through our joint action agency, 51 member utilities own generation and transmission resources, make joint power purchases, and share the cost of implementing new technologies — all of which help members maintain reliable service for the 215,000 homes and businesses they collectively serve.

WPPI Energy’s power supply is diverse, with stable and competitive costs.
