Am I doing something wrong? Electric bill

[GreaseMonkey]

At 2 am, maintenance is over. Here’s my latest bill:

Given that I’m on hourly market pricing, there is no specific cents per kWh for the “electricity supply charge” because the rate changes every five minutes.

My understanding (and I am know to be wrong often) is that the price to compare is equivalent to the combination of electricity supply charge and transmission service charge. If that’s the case, the combo amounts to 5 cents compared to 10.399 cents. So I’m saving about $80 a month being on hourly.

The above savings would have been higher in a normal month. But we took an 11 day vacation and didn’t drive so what is typically 350 kWh of charging the Mach-E ended up being 215 according to my Tesla app. That averaged up the cost. We will also drive less in the summer because we both work from home and the kids are not commuting to school.

Below is Delivery time-of-day pricing sheet (the new program):

I don’t know how you could generate any savings with this rate table (compare tables on pages 1 and 2). The rates for 1-7 pm are double what the regulatory charge is. Need to do more math in the morning.

@kltye, I was wrong. The price to compare is equivalent to the total supply cost, excluding the adjustment. So capacity charge is something that only hourly customers pay. Given that math, my supply cost is around 7.8 cents vs a 10.4. So I saved $39 this month being on hourly, not $80.

Curious to see if you’re faring out better than me.

Anyone has experience with this product:

Seems like a good idea, but wanted to check for practical experience.

I had one and it lasted just over a year and died. I did flash the firmware on it to make it work with home assistant but it was very customizable.

I replaced it with the Meross version that has native home assistant integration, and it seems mostly the same to me.

I live in Hawaii. They put a 30% fuel adjustment charge because of the war. You may want to check to see if you have the same charge. As it is today I pay 52 cents per KW hour. Jealous of you folks on the mainland.

This is a strong possibility for the OP.

Our Hawaii island rates are now 36¢ per kWh off-peak (9 am through 5 pm) and 59.2¢ per kWh during peak hours (5 pm - 10 pm), with a slight reduction after 10 pm through 9 am. Before taxes, fees, and misc gouging. That was before the fuel surcharge kicked in. Everyone here was involuntarily switched to TOU a couple of years ago.

I have a 16 channel setup that I reflashed with ESPHome for Home Assistant like @benk016, don't want Emporia having my data or dropping the product and bricking it when they turn off the server.

No response from OP. Keeps visiting, not replying.

The amount of responses have been overwhelming. So many different newer and possibilities.

Have you read your electric bill to determine your rate?

I’ve had one of these for 3-years. Well, technically the previous version, the Vue 2. Works great. Well worth getting. I use it to monitor all sorts of loads in the house. And I can also monitor solar production and verify what I’m sending to the grid.

Answer = yes.

I would need to opt for a simple version like the Meross. Up until you used the word “flash” in a different context, I thought it is what cameras use for extra lighting. I’m a grease, not a code monkey.

I would definitely recommend the Meross then(or the Refoss it's the same unit).

The new emporias require you to solder onto the board to flash the custom firmware. Although that is only needed if you want to use home assistant and not just the emporia app.

That’s what it sounds like. I have a main and two sub panels with way more than 16 disconnects. Do you know if you can use multiple Meross units and have them feed into the same app? That would be the ultimate solution. I’m indifferent as to what app I use as long as it has good UI and ability to occasionally export data to excel.

The main motivation to doing this for me is to be able to instantaneously identify non-essential power usage and delay them till rates are lower. I am on a market rate that changes every 5 min and my utility penalizes me severely for abnormal usage spikes during high demand periods.

Thanks for your help!

I'm not sure about using two units together, but I would hope you could at least have two units you switch between viewing If it doesn't combine them.

I got about 95% of my usage with only 15 sensors in my panel. But all my light switches are smart and report power usage so they kept me from needing to track any light circuits. And then a smart plugs on the last few things that use much power.

If you're not interested in home assistant at all, I think the emporia is the better unit.

If you drive a lot you will see an increase in your electric bill and I'm gonna say that it might be a shock since you didn't see your EV charging total cost until the bill comes.

TLDR: I paid $90 for home charging for 1533 miles of driving. The gas equivalent at 25 mpg and $3.95 a gallon locally would have cost me $242 in gas charges

With an ICE vehicle at the gas station you are stopping there, squeezing the trigger, and seeing dollars go out of your pocket each fill up.

Even with a credit card that you don't look at for 30 days, you still see the dollars at each pump visit and are aware of it.

With overnight EV charging the Ford app tells you kwh but doesn't give you a dollar number to associate with it.

I drive at least 20 miles each way daily to a sales territory and another 10-40 miles in territory. Weekends can be another 50-100 miles to visit friends and family.

I looked up my recent electric bill (Teco-Tampa Florida) and then looked up my home charging total in the Ford app for the same period that the electric bill covered.

I had 438kwh of EV charging and TECO charges me $0.2069/kwh. So $90.62 from of a $350 bill was EV related. That time period covered about 1533 miles of total driving at an average of 3.5 mi/kwh

The first year of MME ownership, I had been charging DCFC 100% of the time out in the world. Early on, I was quite aware of the costs at Electrify America and thought $0.56/kwh was high.

So I was always looking for the best EV charging rates- like Tesla's early morning discounts around $0.22/kwh (which is no longer available), or out of the way chargers at $0.30/kwh. I found those rates were still cheaper than the equivalent gas price of $3/gal before recent events.

Either way I was aware of the charging cost as I saw the price per kwh and total cost each session with Tesla, EA, and the others.

My Rav4 would get 25mpg and go about 300 miles on a 12 gallon gas tank at $36 a fill up. I've used that as the baseline and comparing DCFC rates. So EA's $0.56/kwh times the Mach-e 91kw battery would be $56 to fill up.

Charging rates around $0.40kwh would be my mental breakeven point unless on vacation or traveling long distance on a time crunch.

Now my home charging at $0.2069 is better than any DCFC rates for early morning and off peak rates.

Thanks to this thread I am researching another use plan from my electric provider and could be at $0.1276kwh for overnight charging. Still verifying that I won't over pay for peak time usage.
