Green Technology GlobalEvery new home needs a primary electricity source. Right now, by default, that's the local electric utility — even in a subdivision built entirely on gas, with the furnace, water heater and range already speced to run on it. FLUX Home closes that gap: a way for builders and developers to make natural gas the primary power source too, on a home that hasn't chosen its electricity provider yet.
New construction is the cleanest window there is
A new home has no standing relationship with the electric utility for primary power. Whoever gets designed in at construction tends to keep that load for the life of the house — which makes new construction the highest-leverage moment to make that decision, rather than a retrofit years later competing against an electric bill the homeowner is already used to paying.
Designed in, not retrofitted
FLUX Home is a compact solid oxide fuel cell — 2′×2′×5′, roughly 600 lbs, indoor or outdoor rated — that runs continuously on natural gas and installs in about a day. Specified into the build alongside the furnace, water heater and range already on the gas plan, it becomes a line item on the spec sheet rather than a special request: utility room space, gas line sizing and panel design account for it from the first drawing. That's a meaningfully different cost position than adding on-site generation after a home is built, where equipment, panel work and gas line upsizing all have to be retrofitted around finished construction.
Relieving pressure on a grid you don't control
Electrification of heating and transport is pushing residential peak electric demand higher, straining feeders and lengthening interconnection queues for new subdivisions. Every home that runs on FLUX Home as its primary power source is a continuous residential draw that never has to be accounted for on the local feeder — capacity a utility doesn't need to plan around, and, in some cases, an interconnection timeline a developer doesn't need to wait on for a new subdivision to energize.
That matters twice over for a developer: it's one less dependency on a utility's own capital planning cycle, and it's a genuine grid-resilience story to bring to permitting and community conversations — a subdivision that's less of a marginal load on an already-strained distribution system.
Lower, more predictable monthly costs for the buyer
Because FLUX Home runs continuously on natural gas rather than drawing primary power from the grid, homeowners pay for their day-to-day electricity through the same fuel already priced into their gas service — a metered commodity cost, not a fully-loaded retail electric bill stacked with supply, transmission, distribution, demand charges, taxes and adjustment fees. Modeled against a household load of roughly 84 kWh per day (a typical FLUX Home output assumption), the numbers hold up across a real range of local energy prices, not just a single best-case scenario:
| Market | Natural Gas Cost | Grid Electricity Cost | FLUX Home Bill / mo | Grid Utility Bill / mo | Monthly Savings |
|---|---|---|---|---|---|
| Lower-cost market | $10.00 / MCF | $0.11 / kWh | $106.69 | $277.20 | $170.51 |
| Below-average market | $15.00 / MCF | $0.12 / kWh | $160.03 | $302.40 | $142.37 |
| Above-average market | $23.00 / MCF | $0.13 / kWh | $245.38 | $327.60 | $82.22 |
| National average | $25.00 / MCF | $0.14 / kWh | $266.72 | $352.80 | $86.09 |
| Higher-cost market | $26.00 / MCF | $0.15 / kWh | $277.38 | $378.00 | $100.62 |
At the national-average scenario, that's a FLUX Home bill of roughly $267 a month against a comparable grid electric bill of roughly $353 — a savings of about $86 a month, or nearly a quarter less, before accounting for the utility fees and rate volatility that a fuel-only gas comparison doesn't carry in the first place. Across every scenario modeled, from the lowest-cost to the highest-cost market, the gas-fired option comes out ahead by roughly $82 to $170 a month. For a buyer comparing homes, that's a tangible number on a spec sheet, not an abstract sustainability claim — and it's one a builder can point to at the closing table.
The FLUX Home figures reflect metered natural gas fuel cost only. The grid electricity figures are inclusive of typical supply, transmission, distribution, demand-charge, tax and adjustment fees — the full retail bill a subscriber actually receives. Actual pricing varies by market and utility tariff.
A differentiator rooftop solar can't match
Builders already compete on energy features. FLUX Home offers primary, continuous power — not backup power that only starts when the grid fails, and not power that depends on sun hours, a battery wall, or net-metering rules that vary by jurisdiction. Installed in about a day, running under 45 dBA at 10 feet, it's a smaller footprint and simpler installation than a standby generator pad or a battery-plus-solar system — while offering something neither backup generation nor rooftop solar fully delivers: continuous primary power the homeowner doesn't have to think about.
How the integration actually works
- Partner & plan: the utility (or FLUX program partner) works with the builder and developer to spec FLUX Home into new home and subdivision plans.
- Design integration: gas line sizing, utility room space and panel design account for FLUX Home from the first drawing — not a change order after the fact.
- Build & install: FLUX Home installs alongside standard gas equipment during the normal construction sequence, with no separate site visit required.
- Subscriber enrolled at move-in: the homeowner's primary power relationship starts on day one — with the gas side of the build, not a later electric utility interconnection.
Bundled into a builder's standard gas package, the install cost spreads across the subdivision rather than landing as a one-off retrofit expense on a single home — the same economics that make any standard-spec appliance cheaper at scale than an aftermarket add-on.
What this means for your next project
If a project is far enough out that gas line sizing and panel design aren't locked yet, that's the window to have this conversation — not after the subdivision plat is finalized. The fastest path is the same one GTG uses for any infrastructure conversation: bring the project stage, unit count and target timeline, and the team can map out what a FLUX Home integration looks like for that specific build.
