El Paso Electric, a utility that serves more than 400,000 customers in Texas and New Mexico, plans to join CAISO’s Western Energy Imbalance Market in 2023.

SPP successfully launched its WEIS market, making it the first RTO with power markets in both the Western and Eastern Interconnections.

SPP regulators agreed to keep up their collaboration with MISO regulators, saying the effort is pressuring the RTOs to resolve their seams issues.

Stakeholders in SPP’s Western Imbalance Service market unanimously approved its Feb. 1 launch, the last major milestone in a project that began in 2019.

SPP staff and stakeholders have added an accelerated decarbonization future to the RTO’s 20-year long-term assessment.

SPP has hired former FERC senior staffer Leonard Tao to serve as its first director of FERC policy.

SPP staff unveiled a proposed mitigation plan to reduce the four-year backlog in the RTO’s generation interconnection queue.

A recent report concluded that a Western resource adequacy program could require state regulators & utilities to relinquish some control over IRP processes.

SPP is attempting to balance staff and stakeholder time spent on analysis and studies with the need to adapt to a changing business environment.

MISO said it will approach SPP about improving the processes underpinning affected system studies in response to stakeholders’ persistent calls for change.
