The Eversource ConnectedSolutions Battery Program - Eversource Energy bets on smarter home storage

The Eversource ConnectedSolutions Battery Program starts right in the basement, where a quiet lithium?ion unit hums next to the washing machine while the summer air outside shimmers above the driveway. In that moment, homeowner Maria Lopez knows her Tesla Powerwall is not just backup, but part of Eversource Energy’s grid strategy.

How ConnectedSolutions works

ConnectedSolutions is Eversource Energy’s demand response program that connects enrolled home batteries to the regional grid and pays customers for allowing the utility to discharge their systems during peak events. The program targets residential and small business customers in Massachusetts, Connecticut and Rhode Island, where Eversource operates regulated electric utilities.

Under ConnectedSolutions, customers install a compatible battery such as a Tesla Powerwall, Enphase IQ Battery or Sonnen system and opt in to let Eversource control limited discharges during high-demand hours, typically hot summer afternoons or cold winter evenings. Events are automated via the battery’s cloud platform, so participants rarely need to touch a switch or app.

Payments and equipment support

Eversource divides its battery demand response into “daily dispatch” and “targeted dispatch” options, each with different payment levels tied to the battery’s average kilowatt output across called events in a season. In Massachusetts, recent program materials indicate incentives of up to roughly 800 to 1,000 dollars per year for a typical home battery in the daily dispatch tier, depending on performance and local tariff structures.

Customers usually buy the battery from installers, but Eversource’s program page lists approved vendors and notes that incentives are paid directly to participants or credited to their utility bills, reducing the effective payback period for the hardware. In practice, installers such as Sunrun and local solar firms bundle ConnectedSolutions into their sales pitch, highlighting that participation can shave several years off the amortization time for a 10 to 13 kilowatt-hour system.

Grid benefits and strategy

On the grid side, Eversource uses ConnectedSolutions to reduce peak load, avoid or defer substation upgrades, and lower capacity and transmission costs in regional wholesale markets operated by ISO?New England. Aggregated batteries act like a virtual power plant, discharging during stress events and recharging when the grid is less constrained.

During a typical heat wave, a cluster of ConnectedSolutions batteries might quietly discharge in dozens of homes while residents watch TV under whirring ceiling fans. Eversource’s operations center sees the effect as a smoother load curve and fewer amber warning lights on transformer monitors, according to company descriptions of the program’s intent.

Customer experience and control

The customer-facing side is designed to be hands-off yet transparent. Participants receive advance notice of planned events via email or app notifications from their battery provider, and annual summaries show how much they earned and how often their system was dispatched. If a user opts out of an event, the battery stays in backup mode, though that may reduce the season’s incentive payout.

Maria Lopez, a fictional composite of typical program participants described in installer case studies, checks her battery app after a July peak event and sees a clean bar chart: state-of-charge dipped from 100 to 60 percent, then recharged overnight from rooftop solar. From her perspective, the main tangible change is an annual check that helps cover maintenance or a weekend getaway.

Leadership view and policy backdrop

Eversource Energy’s CEO Joe Nolan has repeatedly stressed the company’s push into distributed energy solutions, including battery demand response, in earnings calls and sustainability reports. He frames ConnectedSolutions as part of a broader electrification strategy that blends traditional poles?and?wires investments with customer?side resources.

Policy frameworks in New England support such programs. State regulators in Massachusetts and Rhode Island have approved performance?based incentives for utilities that cut peak demand and integrate behind?the?meter resources, while regional clean energy goals push Eversource to replace fossil peakers with flexible load like ConnectedSolutions batteries. That regulatory alignment helps sustain incentive budgets and program continuity beyond pilot phases.

Financial impact and scale

ConnectedSolutions started with smart thermostats and commercial demand response but has added batteries as a higher?value resource over the last few years. Company and installer materials suggest that thousands of residential batteries are now enrolled across Eversource and partner territories, with enrolled capacity measured in tens of megawatts, though exact figures vary by season and technology.

From an investor’s perspective, the program’s direct revenue comes mainly from avoided capacity charges and deferred infrastructure spend, plus potential demand response payments from ISO?New England markets. While those numbers are modest compared with Eversource’s core distribution business, they support earnings quality by reducing exposure to volatile peak?pricing periods and by aligning the regulated asset base with clean?energy policy objectives.

Competitors and technology partners

Eversource is not alone in the battery?based virtual power plant space. Utilities such as National Grid, Green Mountain Power and several California investor?owned utilities run similar programs, but ConnectedSolutions is one of the largest multi?state offerings in the Northeast. That scale helps attract technology partners eager to secure predictable dispatch revenue for their hardware.

Battery manufacturers and software firms integrate directly with ConnectedSolutions via APIs and program rules. Tesla, Sonnen and Enphase, among others, maintain dedicated support pages explaining how customers in Eversource territory can enroll their devices and what performance metrics matter for incentive calculations. This ecosystem approach lowers friction and lets Eversource focus on dispatch algorithms and regulatory reporting rather than device?level troubleshooting.

Risks, limits and customer trade?offs

No demand response product is free of trade?offs. For ConnectedSolutions participants, the main concern is battery availability during rare grid emergencies or personal outages. Eversource and its partners specify limits on depth of discharge and maintain minimum backup reserves to address that fear, but risk tolerance still varies by household.

Battery degradation is another point. Frequent cycling shortens lifespan, yet modern lithium?ion systems are engineered for thousands of cycles, and ConnectedSolutions’ dispatch regime aims to keep cycles within manufacturer specifications. Installers typically model degradation in their financial calculators, showing that incentive payments can offset replacement costs if the battery needs servicing toward the end of its warranted life.

Regulatory reporting and data use

Behind the scenes, ConnectedSolutions requires detailed metering and data exchange. Eversource receives anonymized performance data from battery partners to calculate payouts and demonstrate peak reductions to regulators. That data supports filings at state public utility commissions and ISO?New England compliance reports.

Cybersecurity and privacy are handled largely by the technology vendors, who maintain the cloud platforms that control individual batteries. Eversource’s role is more about aggregated dispatch signals and verifying that events align with tariff requirements and grid needs. For investors and policy watchers, those data flows are a reminder that ConnectedSolutions is as much a software product as a hardware?based energy project.

Market outlook and stock context

Looking ahead, ConnectedSolutions is positioned to grow alongside rooftop solar adoption and state storage incentives in Eversource’s service areas. As more households install batteries for resilience against storms and outages, the pool of potential participants expands, giving Eversource a larger flexible resource to manage extreme days and to meet regional emissions targets.

For holders of the Eversource Energy share, the battery program is a modest but visible piece of the company’s broader grid?modernization narrative, supporting its regulated earnings profile while adding a clean?energy angle that aligns with ESG mandates. On the New York Stock Exchange, Eversource Energy stock trades in US dollars.
