ComEd's load looks like it is on track to be on the top 5 list for the year. Last year, they were between 20 and 21MW. We are right now just under 20MW and growing. It would be so much easier for me to manage my capacity charge if spot price was better linked to load, but I've been fooled by cases where spot price is load but load is max.

Thanks for the heads up. Anyone have a great ifttt setup to catch both load and price?

I had an IFTTT recipe that would precool the house in the morning of expected high capacity alerts and then setup temp very high during the expected peak hours. Sadly, google decided to unlink NEST from IFTTT so this no longer works.

I see comments here about peak ComEd load expected today. While that's true, but I believe ComEd peaks only affect the Network-PLC measure (called NSPL) which only certain industrial and commercial customers pay.

The ComEd "PLC" is based on the 5 peak hours on the entire PJM grid network, which also will peak today. PJM and ComEd often overlap but not always. In other words you want to base your triggers for RRTP ratepayers on the PJM load not ComEd load for Capacity charge control.

Yeah. Luckily I've got an ecobee3.

I'm trying to to better nail my base capacity charge. This year my capacity charge is $43.07 and it's killing me with almost no savings (or negative).

IMHO - 
1.  I would never rely on IFTTT to protect me Capacity Charge Obligation and many other critical things - Flacky at best.
2.  It already appears this year that ComEd or Elevate is notifying us better than the last two years of 5CP ComEd events.
3.  We are always in the dark on the PJM 5CP days.  So may years ago this was not a part of the equation sadly and could be argued that PJM should worry about their hub prices and peak loads seperate from our ComEd hub.
4.  Hard program your schedule with your nest or ecobee, etc to turn off the presence sensor and put in a period of time from 2-6PM that raises the thermostat to 82 or higher to prevent the AC from starting up.
5. Program a precool accordingly for your house up till 2PM latest.
6. Sign up for AC cycling Demand response program if you have not already to help shutdown the AC when ComEd needs it - (Maybe) protects your 5CP ComEd days (Maybe) and you get $40.
7.  Political fallout in your family must be weighed and evaluated on a regular basis for the above behavior changes.

Related to item 6 below, I had signed up for ComEd / Nest rush hour rewards for the same $40 annual bonus. I wonder if that network control still works with Nest integration once Google transitions away from works with Nest.

Gerald, are you sure about that capacity charge? That seems exceedingly high. From you latest bill, what is your kW multiplier in the capacity charge line? Mine is 0.76 (x fixed 5.90804) resulting in capacity charge of $4.49. The kW would be 0.53 crypt for one single large usage last year during a peak load event. I was tricked by the low spot price.

Sadly, yes.Last Month
Capacity Charge 7.29 kW X 5.90804 =  $43.07  

Family was home last summer, I think we must have hit every peak with the AC on max.
Our daily electric last month was 832kWh, total bill was $124.50 with taxes & all

We are probably now near a peak for the PJM load. Last year, they varied between 145,508 and 150,454. We are now at 150,781 and forcasted to get up to peak (150,600) about 3:30.

PJM just went over 152,000.

Old thread, but 7/19/2019 hour ending 6pm EPT did end up being the highest (weather adjusted) peak for the summer.  The weather adjustment procedure is a mystery to me.  Not sure what happened to 7/20/2019 where realtime telemetry showed a peak of 150,800.  It doesn't show up at all on the 2019 5CP list that was published.  

Friday    7/19/2019 18:00 151,295
Wednesday 7/17/2019 17:00 143,001
Wednesday 7/10/2019 18:00 141,560
Monday    8/19/2019 17:00 141,151
Monday    7/29/2019 17:00 139,681

🤷‍♂️
