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 200,000 homes and businesses they collectively serve.

WPPI Energy’s power supply is diverse, with stable and competitive costs. Having held our average cost of wholesale power to members relatively flat from 2014-2018, average wholesale power supply costs to members actually decreased 7.4% in 2018.

We are also environmentally responsible. WPPI has greatly reduced the carbon dioxide (CO2) emmissions associated with supplying power, and we will continue making progress in this area. By 2025, our CO2 emissions will be reduced by approximately 37% from 2005 levels.
