Colorado adopts rule to include storage in utility planning
The Colorado Public Utilities Commission (PUC) has taken a major step toward advancing the state’s use of battery storage, adopting an order on Wednesday to help integrate procurement mechanisms into utilities’ long-term planning processes.
The new rules require consideration of energy storage in utility planning processes, which advocates say is a “critical ingredient” to ensuring customer savings.
State regulators and lawmakers have focused on energy storage in 2018 as the governor signed a measure on consumer-installed storage and the PUC approved an Xcel Colorado plan to retire 660 MW of coal in favor of storage and solar.
Colorado is preparing to boost its use of energy storage, especially since Xcel revamped its energy plan, committing to completely eliminate carbon emissions by 2050, and regulators are beginning to lay out rules to ensure batteries are included in utility planning processes when they acquire supply-side resources. The order approved this week by the PUC codifies the intent of legislation passed earlier in the year.
The new rules “establish requirements for a coordinated electric planning process that is to be conducted on a comprehensive, transparent, statewide basis.” The PUC noted in its order that the commission “does not currently treat all electric facilities alike from the perspective of planning or procurement.”
The Energy Storage Association in a statement celebrated the PUC’s move, saying the new rules “raise the bar for including energy storage in utility planning.”
