Energy Storage in Rhode Island.

Some of the highest residential rates in the country. A 3-8 PM peak window that punishes evening usage. A coastline that takes the brunt of every Nor'easter. A battery in RI does three jobs in one box, and one of them earns a summer bill credit through ConnectedSolutions.

Why now · Rhode Island

Electric bills have climbed every year.

Rhode Island residential electricity climbed from roughly 14.4¢/kWh in 2010 to 31.3¢/kWh today, averaging 5% per year. A battery sidesteps that climb on two fronts: peak-shaving evening kWh, and locking in $225/kW ConnectedSolutions payments for the next five summers.

What a 13.5 kWh Powerwall actually earns.

A single Powerwall 3 (or Enphase IQ Battery, FranklinWH) earns three ways at once. ConnectedSolutions pays $225/kW for letting RI Energy dispatch on summer peak afternoons, locked for 5 summers. Peak-shaving the 3-8 PM window replaces your most expensive grid kWh. And backup keeps the lights on when Nor'easters and storms hit.

01 · Why It Works Here

What makes a battery pay back in Rhode Island.

RI Energy customers with a grid-tied, internet-connected battery (Powerwall, Enphase IQ Battery, FranklinWH, and similar) qualify. The program runs on top of net metering and REG, payments stack on, not in place of, your solar tariff.

03 · Install Timeline

From first call to first dispatch event.

A typical Rhode Island battery install runs 7–12 weeks from first call to Permission to Operate, with ConnectedSolutions activation following shortly after.

01.
Site survey & load study
In-home electrical assessment, panel inspection, NEC 705.12 calculation, ConnectedSolutions eligibility confirmation. Designs the backup loads panel.
Weeks 1-2
02.
Permits + RI Energy interconnection + ConnectedSolutions enrollment
Municipal building/electrical permit, RI Energy interconnection application, ConnectedSolutions paperwork in parallel.
Weeks 3-6
03.
Equipment procurement
Powerwall 3 (or Enphase IQ Battery, FranklinWH) ordered. Lead time 2-6 weeks depending on installer supply allocation. Often overlaps with permit work.
Weeks 4-8
04.
Installation & commissioning
Install is typically 1 day on-site (4-6 hour panel power-off). Utility witness/PTO follows in 3-7 days.
Weeks 7-9
05.
ConnectedSolutions activation
Device enrolled in the program API. First dispatch event timing depends on season: a June install can dispatch within days; an off-season install banks value until the following summer.

04 · Honest FAQ

The honest FAQ.

Actual questions that come up in the first installer conversation, answered for a typical Rhode Island homeowner in 2026.

What if my battery dispatches during an outage?

It doesn't. ConnectedSolutions only dispatches during grid peak events, not outages. Your battery prioritizes your home backup during any grid interruption.

How much can I really earn?

Depends on how much capacity you provide during events. A 13.5 kWh Powerwall dispatching at full capacity typically earns $750-$1,200/year. Opt-outs of individual events reduce earnings proportionally.
