American Electric Power’s (AEP) southwest US subsidiary has issued three requests for proposals (RFPs) to build renewable generating capacity, including as much as 3GW of wind, in six states.

The wind RFP, published by SWEPCO (Southwestern Electric Power Company), is among the industry’s largest historically, reflecting larger utilities ramping up integration of cheaper and cleaner energy sources under pressure from customers, investors, regulators, and the Biden administration's aim of a carbon-free electric grid by 2035.
