Illinois is one of the few states where a real, documented rate change lands on October 1, 2026. Both of the state’s largest utilities reset the default price of the electricity itself (the “supply” part of your bill) for the fall and winter. Ameren Illinois customers in central and southern Illinois see a drop of about 8% from the summer price.

We did not find a Massachusetts residential electricity rate change scheduled for October 1, 2026. Default supply (“basic service”) prices reset every six months, and the most recent reset was August 1, 2026. Prices should hold steady through the fall, then reset again in early 2027. Because that August increase is what most homeowners are seeing on bills now, it is covered below.

We did not find a Michigan residential electricity rate change taking effect on October 1, 2026. Michigan works differently from states with seasonal or auction-based default rates: DTE and Consumers Energy change their rates through rate cases decided by the Michigan Public Service Commission (MPSC). Both got increases earlier this year, and both have new requests pending.

Short answer: we did not find a headline statewide electricity rate change on October 1, 2026 in New Jersey. The big supply-price reset happened on June 1, 2026. What we can document for the fall is narrower: Atlantic City Electric adjusts a supply reconciliation charge twice a year, on June 1 and October 1, and New Jersey’s default supply tariffs are designed with seasonal pricing.

We did not find a verified Ohio electricity rate change taking effect on October 1, 2026. Ohio’s default supply rates for AEP Ohio, AES Ohio and the FirstEnergy utilities were reset on June 1, 2026, and the utilities say they run through May 31, 2027. If you saw a website claiming a new AEP Ohio rate starting October 1, our primary source says otherwise (see below).
