SPP member companies would have to approve any change to this amount. 2 SPA resources include capacity and firm energy from the Southwestern Power Administration.contract 3 GRDA resources include capacity and firm energy from the Grand River Dam Authority.4 KEPCo resources includes WCGS (Wolf Creek Generation Services), SPA (Southwestern Power Admin), Sharpe Generation, WAPA (Western Area Power Administration). They are listed on KEPCo's monthly bill.
