Owned & Purchased Generation
WPPI Energy’s power supply portfolio is constantly evolving to achieve the lowest possible power cost for WPPI Energy members while minimizing price risk. WPPI Energy generates power from our own plants and member generating plants under contract to WPPI Energy.

In addition, WPPI Energy also purchases power under long-term cost-based requirements tariffs and fixed price contracts.
The cost-based tariff purchases, which allow WPPI Energy the flexibility to vary the amount of power purchased from year to year, are maximized when average costs are lower than market costs and minimized when average costs are higher than market costs.
