Reply to comment by rubyslippers3x in Apologies for yet another thread on the new electricity rates coming our way, but for anyone who has yet to switch away from Eversource, I just did it and it took all of two minutes and will save my wife and I tons of money by mikemikemikeandike

New contracts aren’t kw=kw like they were last year. You sell your monthly excess kw at the billing rate and bank that monetary credit.

Similar, but notably different, since in winter when you are using more than you generate, you are buying electricity at a higher rate than you sold your excess for in the summer. Bastards.

And thats why whole home battery backups are worth their weight in gold. Store and then use, even when the grid goes down. I wish there was more education around about the importance of powerwalls and the like combined with solar.

I could not convince myself that a battery made any economic sense for me. It would never pay for itself. The seasonal rate differences are negligible compared to the upfront battery cost. Am I missing something?

Granted, I live in an area with a very stable grid. I’ll probably end up with an EV that can serve as a house backup at some point anyways. The F-150 can already do that I bet other manufacturers will adopt that in the next few years.

Edit: In states with shitty net metering, batteries are essential imo. But CT is still really close to 1:1 net metering.

Yea for so it doesn't make sence but for others it extremely useful. Such as using your solar durring an outage, choosing to toggle between when you charge your battery and when you use the grid durring off-peak hours. Its the closest thing to "off-grid" that you can get. They keep saying that the F150 can but have yet to prove they have the tech to do so, I am extremely hopeful for this though.

As electric vehicles penetrate deeper, I predict electricity will get more and more expensive from 3pm to 10pm to account for everyone plugging their cars in when they get home from work. I think batteries might not make economic sense now, but peak shaving is going to be a more and more important thing to take into consideration. The cannabis legalization in CT will also impact this (It's crazy, marijuana legalization is changing how some major suppliers design power grid equipment and transformers)

That’s fascinating. I hadn’t considered the energy impacts from a changing agriculture industry.

Eversource already has a $200 yearly incentive to encourage charging your EV in off-peak hours. “Off-peak” really only excludes some daytime hours during the hottest days of the year at the moment, but like you said, I’m sure it will become increasingly restrictive.

Can you tell me more about a while home battery backup? Is it a solar powered storage and who would install it, where would I purchase? Thanks!

Yes the battery is charged by solar, however it can also be fed by the grind if you wanted to for some random reason. The DC power runs to the inverter from your panels than once converted to AC power it charges the battery. You can monitor the power draw of your house and the amount of solar energy collected through an App on your phone or computer. Companies like Tesla have solar and batterie packages for sale on their website, but I know the solar company SunRun also sells and installs Teslas Power Walls with their own solar arrays.

Not true. Our contract with ConEd is Kw=Kw. We bank Kw credits with Eversource to use as needed. If we bank more than we use at the end of the year, then we will be paid a miniscule amount like $.04/kw.

Okay, so you signed your contract in 2021 then. I assumed it was this year since your system isn’t live yet.

I’m also assuming you own the panels. I don’t know how lease structures work.

With the 2022 net-metering structure, you bank your excess generation as monetary credits like I described, and tap into those funds in the winter when you are under-producing. Additionally, you receive $0.0318 for every kW you generate. You can only cash out remaining monetary credits when you move, but you are paid out the per kW earnings on a quarterly basis.

No. I signed up this year for installation next year. We are not banking monetary credits. It's kw hour even exchange. Any kw we need in excess of what we bank will be at Eversource current rates. We sized our system to accommodate heat pumps and 2 electric cars... that we don't have yet... because that is allowed. We used 14k kwh last year and we sized our system at 19k kw, so we don't anticipate any need to buy. Yes, this is a purchase. Leasing is a horrible idea.

Okay, guess you got some sort of deal that’s unique from every other CT resident that got solar this year. That’s cool.

Netting incentive from the link you shared:

"Power produced by your system, but not consumed within the month, is "netted" at the same rate you pay Eversource for electricity

Current incentive rate The netting incentive rate is the current retail rate + a quarterly Renewable Energy Certificate (REC) payment of $0.0318 per kWh. This rate is set by the state and remains the same for 20 years."

If I didn't explain it this way, then I apologize. I'm not special. My excess is credited at the same rate being offered, so kw sent= kw purchased. If I need more than I send them I have to buy at the current rate.
