USA: The Southwest Power Pool (SPP) has officially expanded, linking western and eastern electric grids and increasing access to clean energy for utilities across the West and Great Plains, including Colorado, Wyoming, Nebraska, Utah, and Arizona. The expansion allows states and regions to share power, improving grid reliability and offering utilities the chance to buy more affordable wholesale energy.
Environmental groups such as the Sierra Club support regional transmission organisations like SPP for their role in creating efficient, cost-effective energy markets that make better use of wind and solar resources. Jessi Eidbo, Policy Advisor at Sierra Club, said the larger system footprint brings greater resilience, access to diverse low-cost renewables, and efficiencies that can lower consumer electricity costs.
The expansion includes major Colorado utilities, such as Colorado Springs Utilities (CSU), which faces criticism over plans to extend the Ray Nixon coal unit. Public interest groups warn that delaying clean energy adoption could be more costly for customers. Margaret Kran-Annexstein, Director of Colorado Sierra Club, emphasised the importance of utilities seizing the opportunity to reduce fossil fuel use and lower rates while meeting climate goals.
Power providers involved in the expansion include CSU, PRPA, Basin Electric Cooperative, Desert Power Electric Cooperative, Municipal Energy Agency of Nebraska, Tri-State Generation and Transmission, Platte River Power Authority, and Western Area Power Administration’s Upper Great Plains-Western, Colorado River Storage Project, and Rocky Mountain regions.
