Rewiring Utility Planning for the Age of Rapid Load Growth

RMI offers ways to accelerate utility planning and procurement to keep pace with rapid large-load growth and avoid costly over- or under-building of grid capacity. Contact: Charles Cannon (ccannon@rmi.org); attend RMI staff at the upcoming National Association of Regulatory Commissioners Conference in Seattle.

• Main announcement/action: RMI recommends faster, adaptive utility planning and procurement processes to address rapidly rising load forecasts (Engage & Act shows aggregate 2035 demand forecasts rose >20% from Dec 2020 to Jun 2025). Key specifics include Georgia Power’s 2030 demand rising by 7 GW between 2022 and 2025 IRPs, utilities receiving hundreds of megawatts of load requests quarterly, and the IRP update cadence averaging 2.83 years. RMI cites a Virginia utility example estimating ~$2 billion in one-time costs from early overbuilding and a similar ~$2 billion potential loss in Virginia GDP from underbuilding.
• Background and other details: RMI documents concrete planning frictions and proposed fixes: 2 years typical lead time to build fastest utility-scale resources; examples of interim updates include Georgia Power (quarterly large-load updates) and NV Energy (5 IRP amendments in 3 years); proposed tools include stochastic planning, more frequent interim procurements, tariff-based large load options (e.g., Nevada’s Clean Transition Tariff), and alternative modeling approaches explored by Telos Energy and GridLab.
