Eversource Just Filed for an 18% Rate Hike. Here's What Tolland County Homeowners Should Actually Do With That News

Eversource's formal request to state regulators landed this week, and the number is bigger than the 11 percent figure floated back in the spring. Before you panic about next year's bill, here is what actually got filed, why the AG is pushing back, and the electrical upgrades that genuinely blunt the impact.

What Eversource Actually Filed With Regulators

This week Eversource put a formal number behind months of speculation about a coming rate case. The filing asks the Public Utilities Regulatory Authority for close to $727 million in additional annual revenue, framed around a shortfall the company says it needs to cover rising operating and infrastructure costs. Run through the math utilities use to translate a revenue request into a household impact, and the company's own filing points to something in the neighborhood of an 18 percent increase on the average residential bill once storm-related costs are included, or roughly 11 percent if those costs are set aside.

That's a meaningfully bigger ask than the 11 percent figure that had been circulating since spring, when Eversource first signaled it planned to seek a rate case after going nearly a decade without one. Whatever number ultimately survives regulatory review, this is the company's opening position, not a done deal, and Connecticut's rate case process gives PURA broad authority to trim, reject, or restructure pieces of it before anything reaches a customer's bill.

Why the Attorney General Is Pushing Back Hard

Attorney General William Tong wasted little time responding, publicly describing the request as a "tone-deaf insult" aimed at families who are already stretched thin by Connecticut's electricity costs. His office has signaled it intends to challenge the filing through the formal PURA docket rather than just in the press, which typically means expert testimony, discovery requests, and a longer public hearing calendar before any decision.

A bipartisan group of nearly seventy state legislators has separately written to PURA asking for what they've called the most rigorous scrutiny possible on this specific application. That kind of unified legislative pressure doesn't guarantee a smaller number comes out the other side, but it does typically extend the timeline and multiply the number of hearings where ratepayer advocates get a formal seat at the table.

The Fight Over Keeping 300,000 Pages Confidential

A separate but connected dispute has flared up around roughly 300,000 pages of supporting material Eversource wants to file under a confidentiality shield rather than in the public docket. The company frames this as protecting competitively sensitive pricing and critical infrastructure details, not an attempt to dodge accountability. Consumer advocates and at least one state agency see it differently, arguing that a rate case this size deserves maximum transparency, especially in the line items that translate directly into a monthly bill.

PURA will have to rule on the confidentiality request before the substantive rate review can fully proceed, adding another procedural layer to a case that was already expected to stretch well into next year. For homeowners, the practical takeaway is that this is a multi-stage regulatory fight, not a bill that changes next month.

What Tolland County Homeowners Should Actually Do Right Now

Nothing about this filing changes a Connecticut electric bill today, and Eversource itself has proposed a July 2027 effective date if the case is approved as filed. That gives homeowners real runway to work on the one variable they actually control: how much electricity a home needs to run comfortably. In a state where the delivered rate is already well above the national average, every circuit that runs more efficiently is worth more here than it would be almost anywhere else in the country.

That's where an electrical evaluation earns its keep. A licensed electrician can flag where an older panel is forcing inefficient workarounds, whether time-of-use EV charging is actually wired up to take advantage of overnight rates, and whether a home is a realistic candidate for solar or battery storage before the next rate cycle lands. TJF Electric performs these evaluations across Tolland County and Greater Hartford, and a proactive look now costs far less than scrambling once a new rate actually takes effect. This is general information about a pending regulatory matter; specific billing and account questions should go directly to Eversource or PURA.

6 Ways to Get Ahead of a Possible Rate Increase

A rate case can take a year or more to resolve, which is exactly the window to tighten up how efficiently a home actually uses electricity.

1. Get a load calculation before adding anything big: A heat pump, EV charger, or hot tub added to an already-tight panel wastes energy fighting an undersized setup. A licensed electrician's load calculation catches that before the appliance ever gets plugged in.
2. Shift EV charging to off-peak hours: A smart Level 2 charger programmed for overnight hours takes advantage of lower demand and, on time-of-use plans, a lower per-kilowatt-hour rate than daytime charging.
3. Have your panel evaluated for efficiency readiness: Older panels can quietly limit which efficiency upgrades, like solar or a heat pump, a home can actually support without a service upgrade first.
4. Ask about budget billing with Eversource: Budget billing spreads seasonal swings into a flatter monthly payment, which makes a future rate change easier to absorb without a bill-shock month.
5. Track the PURA docket yourself: Connecticut's rate cases include public comment periods; homeowners can follow the docket directly through PURA rather than relying only on news coverage.
6. Prioritize the biggest electricity users first: HVAC and water heating typically dominate a Connecticut electric bill, so efficiency dollars spent there go further than swapping a few light bulbs.

Frequently asked questions

Is my Eversource bill going up 18 percent right now?

No. This is a filed request, not an approved rate. The Public Utilities Regulatory Authority has to review the case, hold hearings, and issue a decision before any new rate could apply, and Eversource itself proposed a mid-2027 start date.

Why did the requested increase jump from 11 percent to 18 percent?

The 11 percent figure was an early estimate discussed before the formal filing. The official request submitted this month came in at 18 percent once storm-recovery costs were included in the calculation.

What is the fight over confidential pages about?

Eversource wants to file roughly 300,000 pages of supporting material under a confidentiality shield, arguing it contains competitively sensitive pricing and infrastructure information. Ratepayer advocates and at least one state agency are contesting that request as too broad for a case of this size.

What can I actually do about a rate increase before it's decided?

Focus on what you control: a panel evaluation, off-peak EV charging, and efficiency upgrades reduce how much electricity a home needs regardless of what the final approved rate turns out to be.
