SPP signaled it may be on the verge of further expanding its footprint, as several Western utilities are committed to evaluating membership.

A request to waive an SPP Tariff requirement prompted a philosophical dispute between FERC Chairman Neil Chatterjee and Commissioner James Danly.

FERC approved penalty settlements for violations of NERC standards by Mississippi Delta Energy Agency and WAPA, along with an unnamed utility.

SPP became the first regional transmission organization to handle RC services in the Eastern and Western Interconnections.

WAPA, Basin Electric, and Tri-State Generation and Transmission Association announced they will join SPP’s Western Energy Imbalance Service market.

Three BANC members and WAPA’s Sierra Nevada division jointly announced they intend to join CAISO's Western Energy Imbalance Market.

An analysis by Eastern RTOs and utilities has found no advantages to changing how they measure primary frequency response.

SMUD said it is canceling a 500-kV transmission line project it was developing with WAPA because it had proven too expensive and was no longer needed.

WAPA said its Sierra Nevada region will go with CAISO for RC services, while its Rocky Mountain and Desert Southwest regions will go with SPP.

The SPP Regional Entity’s Board of Trustees officially terminated the RE’s regional delegation agreement, effective 5 p.m. CT on Aug. 31.
