Your battery, trading.
Grid electricity is priced in 30-minute settlement periods, and the price swings all day. Flux trades your commercial battery against those swings — charging when power is cheap, discharging when it's expensive — replanning its dispatch every ten minutes, around the clock. No trading desk required.
One day of dispatch — teal buys the cheap windows, yellow sells the evening peak.
A battery without market awareness is just storage
Flux is the intelligence layer that makes a commercial battery earn its keep — unattended.
Looks ahead, not behind
Flux forecasts where prices are heading — day-ahead and the intraday balancing market — and plans dispatch over the hours ahead, rather than reacting after the fact.
Replans every ten minutes
Prices land in half-hour blocks; Flux refreshes its plan every ten minutes — charging from solar and cheap windows, discharging into the expensive ones, with no intervention from your site.
Respects your site
Import and export limits, your grid connection, and battery health are constraints inside the optimisation — not afterthoughts.
Any business with a decent grid connection
Battery prices fell by nearly half last year; the grid's price swings keep growing. If your site has a 3-phase supply and room for a cabinet, a trading battery now pays its way.
Manufacturers & works
Flatten the machinery peaks, trim the demand charges.
Farms & rural estates
Big roofs, strong solar — use it when it's worth most, sell when the grid pays.
Cold stores & food processing
Shift the refrigeration load, hold the temperature, cut the bill.
Depots & EV fleets
Charge the fleet in the cheap windows, protect your grid connection.
Community energy & estates
One battery trading for a whole neighbourhood — watch Hazelmead do it live.
Venues & hospitality
Evening trade lands on the evening peak. Buy the afternoon, serve the rush.
The direction of travel is one way: prices swing harder every year, and the sites that can choose when to consume get paid by the ones that can't. Batteries first — EV fleets and heat stores run on the same spine.
Start simple. Upgrade when the numbers say so.

How pricing works
No price lists yet — bands are on the way. But the model is simple, and it's the same for everyone.
For your site
A simple monthly subscription per site and edge controller, banded by the size of your grid connection. The hardware is yours; the intelligence is subscribed. Talk to Simtricity for your band.
For Installers
Referring costs nothing. Your customer lands on Basic Flux when your install is done, and we look after them from there — you keep the customer relationship at the point of sale.
For VPP Developers & Operators
A fixed-scope Runbook engagement stands up your Flux service — the basis for your VPP — then we take a share of the trading uplift your VPP creates. Read about running a VPP on Flux.

Win the job with a battery that earns
Lead your proposal with Simtricity Flux as your technology partner. A quote with an earning battery beats a quote with a passive one. And when your install is done, we look after your customer on Basic Flux — they can upgrade to a VPP themselves later.
