How it works
Battery storage creates value locally only up to about 20% of the year. The rest of the time, we trade the battery on the energy markets: buying electricity when it's cheap, selling when prices are high. That way, the battery earns you value around the clock, not just when it's shaving a peak. Your on-site use cases always come first. Trading only happens with what's left over.
Your upfront cost is €0. We finance, install, and operate the battery storage system at your site, and combine your local use cases with additional energy trading. This way, your battery earns you something, even when you're not using it yourself.
The real challenge in trading with battery storage is that how much it can charge or discharge changes dynamically, in real time, and your on-site use cases always have to come first. Our team has years of experience doing exactly this. We take on that operational complexity, so none of the risk falls on you. And because we handle it all in-house, we can act quickly whenever conditions change.
Whenever your battery storage has spare capacity, we put it to work: trading on wholesale markets, correcting real-time imbalances, and getting paid by grid operators for standing ready or offering up capacity you're not using. Here's how each one works.
We buy electricity when it's cheap and sell or discharge when prices rise, automatically and around the clock.
When the grid's actual supply and demand shift from what was predicted, we adjust your battery's position in real time and get paid for it.
If your site has enough flexible power, your battery can get paid by the grid operator just for being available to help stabilize the grid, and paid again when it's actually called on.
Energy trading example
How Bnewable's energy trading maximizes your battery storage utilization, 100% of the time
07:00–09:00 peak shaving
The load ramps up to 3,300 kW as your industrial site starts up. Bnewable's battery discharges to cap that peak, lowering your site's grid capacity charge every month it happens.
11:00–15:00 self-consumption
Midday solar output exceeds what your industrial site needs, and net load dips to -550 kW, power your site would otherwise sell at rock-bottom prices. Instead, Bnewable's battery stores it and heads into the evening already charged.
The rest of the day: energy trading
For roughly 84% of the day, the battery isn't needed for anything else, so it's free to charge and discharge purely on price: day-ahead, intraday, or the imbalance market. Stack all three, and one battery earns nearly around the clock, instead of sitting idle once its one job for the day is done.

Battery-as-a-Service
Your project with Bnewable follows the Battery-as-a-Service model: you pay a fee only when the battery is actively lowering your electricity costs, and you keep the larger share of those savings. The rest of the time, Bnewable trades on the energy market using your battery, and you get a cut of that too. Either way, you reduce your energy costs and receive extra income, with no investment, and no extra staff required.
