SPP Grid
Southwest Power Pool. Tracking wind integration, transmission buildout, and regional market design.
The SPP Region
SPP operates the grid across America's wind belt, from the Dakotas through Kansas, Oklahoma, and into the Texas Panhandle. The region leads North America in wind energy integration, regularly exceeding 70% renewable penetration. SPP's $7.7 billion transmission expansion plan will unlock even more wind capacity and improve regional reliability. The grid also serves as a key corridor for major HVDC transmission projects.

Wind Integration Records
SPP regularly sets records for wind penetration, sometimes serving over 75% of load from wind alone. This tests grid flexibility, storage needs, and market design for negative pricing events.
-
Transmission Expansion
SPP's $7.7B transmission plan addresses congestion in the wind belt and unlocks export capacity to neighboring regions. Key projects connect Oklahoma and Kansas wind to load centers in the South and East.
-
HVDC Transmission
Planned multi-GW HVDC transmission lines would export wind energy east, representing some of the largest clean energy infrastructure investments in U.S. history.
-
Winter Reliability
Winter storms have tested SPP's grid repeatedly. The 2021 and 2024 cold events forced emergency actions and highlighted the need for winterization and fuel security.
-
Markets+ Competition
SPP is developing Markets+ to compete with CAISO's EDAM as the organized market for the Western U.S. The outcome will shape grid governance and market structure across the West.
