Are you based enough to charge VPPs for transmission and deep network upgrades? It sounds like Joe Bowring the PJM market monitor sure is!

Hey @mayorwu.boston.gov thanks for finally doing something smart and plowing over the bike lanes on Western Ave for the snow. Big improvement from last year when you kept them up and MUCH safer

VPPAs like this should be greatly discouraged by matching and deliverability requirements. Buy energy that you can plausibly use please!

Impressive we've burned through about 40 million gallons of fuel oil in ISO-NE the last ten days or so..this represents about 1600GWh of fuel energy or about 600GWh or so of electrical energy. Or about 7.62 million Hyundai ioniq long range. Cost of the fuel: $140m @$3.50 Ioniq cost: $342b

There you go a million Hyundai ioniqs at a capital cost of 50b and you get 1GW for three whole days. That's a lot more likely to add to the load than to supply it too 😂

As an EE I know full well the effect on all NERC contingency planning standards when you take away the option of injecting power as long as you need to wherever you need to in the network. And power plants that run without duration limits by converting molecules might be pretty key to that...

AI tipped me off to this, but Eversource East is now issuing close to 250 mil in net metering credits (to be recovered from non solar ratepayers) for a total revenue requirement of 1.3 billion. This seems... significant. Taking the worst of CA's energy policy is unsustainable. Who woulda thought

Probably about £200k per half hour – less than a penny per bill-payer. Over the next few months the final pieces of equipment (synchronous compensators; flywheels attached to motor/alternators) will be installed and we will be able to operate without gas when conditions allow

The number of people who've been like "see this has nothing to do with renewables" as soon as it didn't seem to be an inertia issue have... Puzzled me. Like ok, let's say inertia had nothing to do with it: this is still a huge example of why VRE has made grid management more complex and risky

Re: blackout. Focus on the reactive power capability of the thermals I have to say this is akin to blaming a fire that burned down the neighborhood because the fire hydrants were 30% low on pressure instead of the pile of combustibles one of the homes happened to leave next to the open pit bbq.

On Spain, I think Xiao has it right here, if not elsewhere in his response to @janrosenow.bsky.social. If the question is whether renewables-heavy grids are fundamentally unstable, then the answer is no. If the question is whether such grids require more rigorous management, the answer is yes.

Exactly as I said after the blackout: voltage regulation was issue, not a lack of spinning inertia, as so many quickly speculated (or asserted). It was an off peak spring day, plenty of cheap solar available, and the grid operator cut it too close, failed to commit sufficient voltage regulation.🔌💡

Well speaking with hindsight all that focus on additionality in blue state REC portfolios seem to be a big self own. Should have locked up the nuclear on a PPA that was $10 more expensive than the gas plants than dally in all that offshore wind and BTM/community solar. Can't cry if someone took it.
