The Maine PUC denied CMP's temporary $7-a-month increase request on October 6, 2026, so that charge will not appear on bills. The larger, separate request that could add about 18 dollars a month is still pending and is not expected to be decided until spring 2027.
BGE has asked to raise electric bills about 8.18 dollars a month starting in 2027, including a 17 percent jump in the distribution charge; public hearings run through November 18, 2026 and nothing has been approved yet.
If regulators approve it, Oracle would cover part of We Energies' nuclear power costs instead of spreading them to all customers, which the company says will lower everyone's fuel charges rather than raise them.
RG&E customers are on temporary rates while the commission reviews a much larger permanent increase request.
The 83-therm baseline here is monthly usage for a typical RG&E heating customer.
This pending case would raise your Avista electric bill starting January 2027; the state Attorney General is fighting part of the request.

If approved as filed, this would add about 23.88 dollars a month to a typical OG&E Oklahoma bill; nothing has been decided yet.
If approved as filed, this would be a bigger increase than the 4.1 percent DTE got approved in its last case; MPSC Staff and the state Attorney General both want the increase cut well below what DTE asked for.
Transmission upgrades like this are typically billed to every electric customer in the state through transmission charges, not just to the data center that made the new line necessary, which is why the cost allocation question matters for ordinary bills even outside the counties involved.
This is Evergy's opening ask for its Kansas City area customers; the company already cut it once because of new data center revenue, and the case is now in its evidentiary hearing with no decision yet.
Delmarva Power has an interim increase of about 34 million dollars in effect since July 2026 and is appealing how it was calculated in court; a final decision on the full 75.8 million dollar request is not expected until 2027.
This case will set your SDG&E electric and gas base rates from 2028 through 2031; it is very early in the process and the numbers will change.
This case would raise your PSE electric bill in stages starting in 2027; nothing has been decided yet.
This case would raise your PSE natural gas bill in stages starting in 2027; nothing has been decided yet.

This is a small, gradually rising charge if approved: about a quarter a month at first, growing to under a dollar a month over a few years; it has not been decided yet.
If approved as filed, this would add roughly 5.3 percent to a typical Potomac Edison Maryland bill; nothing has been decided yet.
Montana-Dakota Utilities customers in North Dakota are already paying an interim increase of about 12.90 dollars a month while regulators review the full 14.5 percent request.
This is new state law aimed at keeping data center power costs off your bill; the CPUC still has to write the actual tariff rules, due by January 1, 2028, so there is no bill impact yet.
