What is Changing in SPP
The Southwest Power Pool (SPP) will launch its RTO Expansion (RTOE)—one of the most significant structural changes in US wholesale power markets in recent years.
The initiative expands SPP’s Regional Transmission Organization into the Western Interconnection, making SPP the first RTO to operate organized wholesale markets across both the Eastern and Western interconnections.
For market participants across the region, the expansion represents more than a geographic shift. It introduces new pricing nodes, additional trading opportunities, and changes to how data is published—while also increasing complexity across market participation, settlements, and operational workflows.
