In her testimony #FERC Chairwoman Swett said, several times, that a third of consumer bills come from rates overseen by FERC. Has anybody (can anybody) break this down with more granularity?

Lots of problems with the #NERC Reliability Report, but this is a doozy โ€œโ€ฆIBRs provide little or no frequency response capabilityโ€ฆโ€ Lots of data showing this is just flat wrong.

๐ŸšจThe ban on aggregators of demand response participating in wholesale markets in Minnesota was reversed by the MN Court of Appeals. FERC could step in now and free the rest of MISO and SPP states by lifting the opt out in O719.

The use of Section 2 of the Sherman Act would be a novel, but potentially effective, application of anti-trust law in the electric power market sector.

My understanding is that it is SERVM. But not confirmed. That model is used elsewhere for sure. Including SPP. My *guess* is itโ€™s a unique MISO application.

๐ŸšจPretty big news out of MISO this morning. A continuing LOLE error that has existed since 2017 has resulted in a "total financial impact based on net positions [of] approximately $280 million." In other words, load was over-charged.

This could have been stood up through FERCโ€™s OPP. In fact, numerous groups encouraged this in their comments regarding the creation of that office. If this is so important, why didnโ€™t he just do it? He had every opportunity as Chairโ€ฆ

It is not only a problem of delays related to turbine production, but there are additional delays layered on top of that, including labor shortages and specialized materials delays as well.

100% Self-Commitment RMIโ€™s Utility Transition Hub helps key stakeholdersโ€”regulators, investors, policymakers, advocates, and utilitiesโ€”chart a path to an equitable and affordable energy transition

New data from @rockymtninst.bsky.social shows every U.S. state would have lost more money in 2024 if their coal plants had been self-committed 100% of the time. #EnergySky

With the Campbell 202c order, DOE is attempting to make RMR-like decisions that are unwarranted. DOE cites NERCโ€™s summer assessment report as support, but even MISO, its market monitor, and at least one of its member states (Wisconsin PUC) think that the report lacks merit.

Is your electric bill too high? Thank LNG exports. Allowing more gas to be sold overseas gives a windfall to corporate executives who profit from exports as well as from the higher prices they cause here at home by creating scarcity in the market.

Yesterday, Earthjustice filed comments in FERCโ€™s co-location docket (EL25-49).

The demand for co-location is largely driven by developersโ€™ desire for speed to market, but speed to market should not, and cannot, result in sacrificing comprehensive system planning.

PJM badly needs to tighten up their large load adjustment forecasting process that essentially accepts whatever forecast the Utes allege (who all use wildly different forecasting criteria!).
