For landlords with 1–25 rentals
GrooveGrid is rental energy readiness for small landlords — built on the Project Flux platform. We measure how each building performs, surface the opportunities hiding in your utility data, and help tenants and owners stay ahead of cost, comfort, and incentive deadlines. [How we measure →]
Think of it as your own energy grid for the properties you own — a private decision grid across your rentals, not a utility control room. You see how each building performs, what to do next, and where the dollars are. The utility still runs the meter; you run the calls that affect your portfolio.
Savings estimates vary by property, equipment, and utility. See our methodology.
Powered by Project Flux
Flux gives each customer their own private property energy grid — a decision layer over the rentals they own. It is not utility grid control and does not dispatch the public grid.
The small-landlord product. Comfort-first rental energy readiness for owners running 1–25 properties.
The signal layer. Reads utility, weather, and equipment data — under customer authorization, minimum necessary — so each building has an honest picture of how it actually performs.
The analytics layer. Turns those signals into ranked opportunities, incentive matches, and reporting-ready summaries you can act on across your portfolio.
Trust by design
You connect your accounts. We read what you authorize — utility data through Green Button or comparable consented channels — and only the minimum needed to score the building.
Models are tuned on building performance, weather, and equipment health — not personal household behavior. Read-mostly by default. Resident comfort is preserved.
Bills, meter data, equipment telemetry, and property records are handled with encryption in transit and at rest, scoped access, and clear retention. You can disconnect any account at any time.
How it works
GrooveGrid plugs into the utility accounts and equipment you already have. Flux EQ collects the signals, Flux Insight ranks the opportunities, and you get a clear shortlist of what would actually move the needle on comfort, cost, and readiness. What you end up with is your own customer energy grid: a private decision layer across your rentals, owned by you — separate from the public utility grid.
Cloud setup connects in ~5 minutes through Green Button or Bayou. Flux EQ starts reading bill, interval, and weather data — no hardware, no site visit, no tenant disruption.
Flux Insight benchmarks each property against weather, climate zone, and building type. We measure how the building performs — not personal behavior — so you can see comfort risks, drafty envelopes, and oversized bills before tenants do.
Owner-paid waste, tenant cost pressure, missed Mass Save / HEAR / weatherization incentives, avoidable repairs, and what to upgrade first — ranked. We line you up with vetted contractors and program partners when it's time to act.
Tenant-safe by design: GrooveGrid measures building performance, not personal behavior. We don’t monitor occupancy patterns or override thermostats tenants control. When a smart thermostat is on the owner’s account, we can suggest schedules — but comfort bands stay where you and your tenants set them. Connections are read-mostly by default; we use the minimum signals needed to score the building, under your authorization.
Where the opportunity lives
For a typical 2-bed New England rental (700 kWh/month at 29.4¢/kWh), the meter reads about $2,466/yr. The real opportunity sits in five places — some owner-paid, some tenant-paid, some on the calendar, some in the repair budget. We surface all of them so you can act on the ones that matter most. [How we measure →]
Tenant-paid utilities? We never assume a landlord controls tenant comfort. The numbers below are an estimate of the opportunity that exists in the building — to be claimed by the right party with the right work.
| Opportunity area | Who benefits | Annual range |
|---|---|---|
| Owner-paid waste common-area loads, idle equipment, oversized gear on the owner’s meter | Owner | $120 – $400 |
| Tenant cost pressure relieved envelope, equipment, and scheduling improvements that lower bills tenants pay | Tenant | $200 – $550 |
| Missed incentives captured Mass Save, HEAR, HEAT Loan, weatherization, utility programs you currently qualify for | Owner | up to $8,500+ one-time |
| Avoided repairs equipment trending poorly, freeze risk, moisture & ventilation flags caught early | Owner | $300 – $1,200 / event avoided |
| Upgrade prioritization ranked: heat pump, insulation, water heater, weatherization — by payback & deadline | Both | payback weeks vs. years |
| GrooveGrid subscription | Owner | −$240 |
Illustrative ranges for a single 2-bedroom rental. Estimates draw on regional utility rates (EIA January 2026) and typical 2-bed apartment consumption of 700 kWh/mo (ACEEE). Tenant-side ranges describe opportunity inside the building — actual realization depends on the work done and who pays which utility. Incentive figures depend on income, equipment, and territory; we surface what you qualify for and connect you with program partners. See our measurement methodology for how we attribute and report.
If you have a battery
If a battery is already installed on the owner’s side of the meter, programs like Eversource’s ConnectedSolutions pay you to share capacity during grid peaks. Flux Insight checks eligibility, models revenue, and flags it alongside everything else worth doing.
Up to $4,388/yr from a Tesla Powerwall 3 enrolled in ConnectedSolutions on Eversource at 2026 rates. Legacy 5 kW systems earn ~$1,485/yr. [How we measure →]
Source: Eversource ConnectedSolutions — Battery Storage. You keep full backup use of your battery; the utility dispatches only during declared peak events. Tenant comfort isn’t affected.
per Powerwall 3 enrolled on Eversource
Powerwall 3 is rated 13.5 kW; 13.5 × $325 = $4,388. Actual revenue depends on battery model, utility territory, and dispatch performance. See methodology.
Programs & partners
We don’t replace your contractor or your utility’s program. We make sure you don’t miss them. GrooveGrid lines up Mass Save-style programs, weatherization, heat-pump incentives, and vetted contractors against each property — so you can act before deadlines and before a tenant calls.
Whole-home heat pump rebate for qualifying installations in standard investor-owned utility territory. Weatherization (insulation, air-sealing) is often 75–100% covered for eligible buildings.
CMLP/WMLP municipal territory customers may qualify for up to $10,000.

Federal Home Electrification and Appliance Rebate for qualifying heat pumps, income-dependent. Stacks with state and utility incentives when run through approved contractors.
Source: DOE Home Energy Rebates
7-year, zero-interest financing up to $50,000 for qualifying energy-efficient equipment in MA — useful when you need to bridge the gap between rebate paperwork and contractor invoice.

The federal 25D residential solar credit expired Dec 31, 2025. State and utility incentives — including MA-SMART, ConnectedSolutions, and weatherization tracks — remain. We keep the calendar so deadlines don’t catch you out. Source: IRS — Residential Clean Energy Credit. [How we measure →]
Pricing
Most New England customers see the subscription pay for itself in month one through a mix of waste, incentives, and avoided repairs. Other regions: 2–3 months depending on utility rates and what we find. [How we measure →]
