SPP is stepping up its bid to offer market services in the Western Interconnection, with interested participants approaching the RTO for more details.

AEP beat analysts’ expectations for the first quarter and completed a deal with Sempra Energy that added more than 700 MW of wind generation.

SPP General Counsel Paul Suskie laid out the implications of FERC’s reversal of a waiver it had previously issued to the RTO on Tariff Attachment Z2.

FERC ordered SPP to eliminate its membership exit fee for non-transmission owners, granting a complaint by wind developers.

FERC issued deficiency letters to all six jurisdictional RTOs and ISOs over their proposed energy storage rules, pressing for definitions, tariff citations and other details.

The SPP-MISO Joint Planning Committee has voted to begin a new coordinated system plan this year, SPP staff told the RTO’s Seams Steering Committee.

Despite the ongoing shift to renewables, the Eastern Interconnection has sufficient inertia to maintain system frequency for at least the next five years.

SPP has made its long-held interest in the West official by “calling on interested utilities and other customers” to help build a real-time market “that will meet the electricity needs of the Western Interconnection.”

The Midwest Reliability Organization Board of Directors reviewed the transition of former SPP Regional Entity members to MRO.

FERC denied KEPCo’s complaint that Westar Energy had twice violated its generation formula rate in assessing its own rates and federal income tax reduction.
