When I said this was HUGE, it might not be obvious to even the rarefied air of #energytwitter why I'm so amped about @FERC approval of @pjminterconnect capacity accreditation reforms for #energystorage.

Allow me to explain... (thread alert!) 1/

@FERC @pjminterconnect First, grid operators can now compare how #energystorage contributes to power system reliability on an apples-to-apples basis with fuel-based generation. It's a definitive statement that "yes, storage can be counted on for reliability" and answers analytically how much 2/

Q for power system modeling nerds: does a forced outraged adjustment to calculate UCAP inherently assume that generator outages are 1) equally likely over time and 2) of equal magnitude? Is there anywhere that UCAP is adjusted based on weather covariates, at least for planning? Cc @EricGimon @JesseJenkins @gogginmichael @NrdcTomr @EnergyBetty @davidrmillar

13 minutes into my daughter's virtual 1st grade. We are still working on everyone muting and unmuting themselves effectively. Going to livetweet today's session to give folks a view into what this looks like... As the teacher goes one by one calling on students to say their favorite animal (7 min for 16 kids), intense fidgeting and easy disengagement. Kiddo runs off camera, I remind her to stay on camera.

Key update on #EnergyStorage-as-transmission! @FERC accepted @misoenergy's "storage-as-transmission-only asset" (SATOA) proposal, subject to a further tariff filing by 9/24 elibrary.ferc.gov/IDMWS/common/o…

A thread on the issues in the order and some observations 1/ First, FERC approves the basic premise of MISO's SATOA, noting it as an extenstion of the Western Grid precedent that established storage-as-Tx. No real suprise there, other than that it re-affirms the distinction from NTAs 2/
