All opinions my own.
It’s bundled into the kWh rate for most, but here’s a direct example of how it will increase when broken out as a separate line item.

An increase from $0.91 to $8.34 per kWh. At 3kW it’s $25. You’re paying a Netflix subscription every month for capacity.

I suspect flows are generally into PJM during peaks, but out of PJM during cool days like today

On device level metering, PJM states AEU “misreads the first compliance order entirely”.

#FERC already approved PJMs approach to device level metering and they’re not going to entertain alternate options until after initial implementation

#PJM has responded to Advanced Energy United’s complaints of their last #FERC 2222 filing.

Things are getting spicy.

PJM says of #AEU characterization of the cost of metering as a barrier to entry, “may be valid in their minds”.

It’s not PJMs problem, take it to the state regulators #energysky

So… PJM sync reserves are worthless? What does this mean? #energysky

Reducing this charge is simple in principal. Reduce consumption during the five peak hours on the system. The difficult part is timing.

But using #HomeAssistant, timing the peak was simple.

Monitor the load, and the derivative of the load is the slope. When the slope is 0, that’s the peak.

My utility #ComEd, has a hourly pricing program that gives participants direct exposure to wholesale market prices.

My bill includes a line item for capacity that is calculated based on my Peak Load Contribution (PLC)- my average usage during the previous summer’s five PJM system peaks.

This summer I used #homeassistant to manage my usage during PJM’s 5 coincident peaks. Which should save some serious money on my energy bill. #EnergySky

Let’s see how I did:
