Southwest US Grid expands into the West

SPP reported that energy regulators approved Thursday the Southwest Power Pool's expansion of its territory. The pool will become the first regional U.S. electrical grid to operate both in the western and the eastern interconnections.

Why it's important

SPP is one seven regional transmission operators (RTOs) that control the flow of electricity, as well as the markets which facilitate it. These RTOs compete for members and territory.

SPP, who runs the bulk grid and wholesale market for power in 14 states of the West and Midwest, will extend its reach under an agreement signed unanimously by the U.S. Federal Energy Regulatory Commission to include all or part of 17 states.

CONTEXT

In April 2026, seven power providers who currently have a limited interaction with the SPP will be able to participate in broader markets, transmission planning and grid services.

These potential new members are: Basin Electric Power Cooperative; Colorado Springs Utilities; Deseret Power Electric Cooperative; Municipal Energy Agency of Nebraska, Platte River Power Agency, Tri-State Generation and Transmission Association and Western Area Power Administration Colorado River Storage Project in the Rocky Mountain and Upper Great Plains Regions.

KEY QUOTE

In a recent statement, Colorado Springs Utilities' Chief Executive Officer Travas Deal stated that an adaptable grid with access both to local and regional resources was essential for managing costs and maintaining service quality.

We are confident that the SPP RTO can help us reach this goal. (Reporting and editing by Scott DiSavino, Ni Williams and Laila Kearney)
