It’s not that “*PJM’s model* is structurally anti-growth with a poorly designed capacity market”
It’s that Capacity Markets as a concept are poor market design and anti growth, period
The fact that the BRA doesn’t function at PJM scale is an artifact of a suboptimal protocol not suboptimal implementation by the grid operator
$12B of US ratepayers' money wasted on a modeling mistake
and PJM wants to do it again.
American Grid design needs an overhaul,
Why it is good to be full of cold air.

How ERCOT looks at PJM when it hears it may be considering changing to an energy-only market.

The point here is that as a retail consumer your advocacy should demand efficient tech-agnostic market design. The only ally of the consumer is stable price formation and competition.

Many of the people that talk about demand flexibility have not come to terms with the reality of how inelastic electricity demand is most of the time.

PJM made the fatal flaw of trying to treat capacity for resource adequacy as a centrally planned commodity 20 years ago and has damned all of its stakeholders to an eternity of arguing about meaningless metrics ever since
Just to clarify here: PJM assigns a 92% ELCC to DR that is required to be available ALL 8760h of the year.
With regards to large loads, Google-Amazon-Microsoft have instead asked PJM to create a new data center DR product capped at 100h/year + requested PJM to estimate the appropriate (much lower) ELCC for it.
Data Center Coalition in its proposal asked PJM for a new limited DR product capped at 240h/year
If the existing 8760h DR product was good to go for data centers we wouldn't see requests for new products.

Monitoring Analytics reports on @pjminterconnect & has people losing their mind. Firstly, pls, read it: monitoringanalytics.com/repo… TL;DR: prices w/ #DataCenters (DCs) will sky-rocket regardless of demand response commitments. For a 🧵on DCs & capacity #regulatory #fiction 👇 -1/n

Been talking about this for months not just to people in ercot but also ICE. Bilat market also shows very little interest in offering RT settle AS which is surprising given RTC go-live upon us. One issue is most buyers (which are LSEs or load) are not even paying attention yet that they need to fill this exposure…this aint no SASM lol. If you know anyone interested in offering DM me. We are buyers.

Now, utilities, who never would dream of inflating a load forecast only to justify a bunch of rate-based spending on the grid, or to spin legislators into a tizzy to pass self-serving legislation -- well, akshually maybe there's an eentsy bit of moral hazard at play...

WSJ: Natural gas is “the clear winner” for powering AI data centers:
‘Billy Sorenson, Lightfield’s founder, has developed and built solar projects for the past 15 years but said only natural gas has the power density to meet AI demand.
“All roads point to natural gas,” he said.
…
“As utilities push to increase supply and access, data centers are pulling in resources wherever they can, with natural gas the clear winner.
Massive turbines for large power plants have a yearslong backlog. But smaller turbines,
reciprocating engines or fuel cells that also can use natural gas remain available—for now.
Companies are snatching them up”
The AI race is driving an energy Wild West that is reshaping American power. “We want as much flexibility in our power supply as we can get.” on.wsj.com/3W4pkYh

Our article "Operational Uncertainty and the Missing Money Problem" is now in Energy Economics (link below). The paper investigates capacity markets and operations, finding that current configurations in US markets slightly undercompensate baseload plants relative to peakers.

What this is really showing is our grids are being asked to do more than it was built for. Your bill pays for two things: electrons and plumbing. The electrons (wholesale power) haven’t been persistently expensive, natural gas has even been cheaper at times but the plumbing (poles, wires, substations, transformers, wildfire hardening, storm resilience, cyber, and interconnection work) is exploding in cost. Utilities are pouring record capex into a network that’s old, congested, and not designed for data center clusters, EV charging, heat pumps, or extreme weather. Those dollars get rate based, and with higher interest rates the carrying cost of every new project is bigger, so the price per kWh drifts up even when fuel isn’t the culprit.
On the supply side we retired a lot of firm coal and nuclear faster than we added firm replacements. Wind and solar help on energy, but they don’t always show up when the grid needs capacity. That means paying for backup like gas peakers, batteries, and capacity payments plus more transmission to move surplus from where the wind blows to where people live. Until long duration storage and new firm low carbon generation scale, we’re running a two system grid: one to harvest cheap variable energy and another to guarantee reliability. Two systems cost more than one.
The bottleneck now is wires and time. Interconnection queues are jammed, permitting takes years, and congestion rents rise because power can’t get to load without expensive detours. Add regional issues like wildfire mitigation in the West, gas pipeline constraints in the Northeast, hurricane hardening in the South and you get a national average that climbs even when wholesale prices don’t.
Bottom line is prices are signaling infrastructure strain. If we want cheaper, steadier power, we need to build the boring stuff faster (transmission and distribution), add firm, clean capacity (nuclear, advanced geo, gas with carbon management), scale storage, and use smarter pricing so demand shifts off peak. Until then, the chart is less about electricity being scarce and more about a grid that’s being stretched and financed like never before.

Nobody wants to let LMPs go high enough for data centers to curtail on economics so everyone's coming up with proposals to force it as a condition for transmission service which just seems ass backwards to a markets guy like myself but we're all at the mercy of politics.

The basic problem with capacity markets is that that have so many regulator-degrees-of-freedom that they become less and less a market and more administratively set capital recovery
