Bring-Your-Own and Clean Transition Tariffs for Data Centers

RMI has published an insight brief proposing Bring-Your-Own (BYO) and Clean Transition Tariffs to meet large customers’ energy needs while protecting other ratepayers.

• Main action: RMI recommends baseline large load tariffs complemented by voluntary Bring-Your-Own (BYO) and Clean Transition Tariffs to accelerate clean resource deployment and allocate cost/risk to participating large loads. Key concrete examples cited: PJM’s Bring Your Own New Generation Program (proposal for generators greater than 250 MW, board letter dated Jan 16, 2026), Tri-State’s member cooperative self-supply program, Evergy Kansas Large Load Rate Plan settlement including a Clean Energy Choice Rider (settlement document referenced), NV Energy’s Clean Transition Tariff used by Google to procure an enhanced geothermal system toward its 24/7 clean energy goal, and Georgia Power’s 2025 IRP addition of a Customer-Identified Resource (CIR) option to CARES.
• Background and details: BYO tariffs are presented as a voluntary pathway alongside a “baseline” large load tariff and can support multiple procurement types (Utility-Owned, Utility-Contracted (sleeved PPA), Customer-Contracted (physical PPA), Customer-Owned/behind-the-meter). The brief advises regulators to require emission impact assessment and reporting, validate inclusion of BYO-procured resources in long-term planning to avoid redundant builds, and consider pairing BYO with interruptible service tariffs and virtual power plants to capture flexibility.
