This report provides electric cooperatives with information regarding development and implementation of EV charging programs and rates. These multifaceted efforts require careful consideration of numerous factors, such as grid needs, member preferences, grid infrastructure planning, renewable energy penetration, tradeoffs between simplicity and choice, and much more. Without well-designed programs, EV charging loads may eventually increase cooperatives' peak demand, adversely impact grid operations, and raise grid costs. Higher grid costs can in turn increase costs for cooperative members. As EV adoption accelerates, the potential risk of grid impacts increases. However, EV adoption also creates opportunities for cooperatives to optimize grid assets, expand consumer options, and strengthen member relationships.
This report includes in-depth EV program case studies for two distribution cooperatives: Roanoke Electric Cooperative and Wright-Hennepin Cooperative Electric Association. These case studies explore a wide range of issues, including objectives, power supply costs, technology deployment, pilot programs, EV subscriptions, TOU rates, member education and marketing, member input and feedback, public charging, and school bus charging. A third case study for Western Farmers Electric Cooperative, a generation and transmission (G&T) cooperative, focuses on its initiative to deploy a statewide fast-charging network in Oklahoma as well as associated educational activities.
