Raido Seppam: The One Pain Point All EPCs Share

Managing a hybrid energy site is a juggling act. Renewable production, battery storage, onsite consumption, and a market that moves by the hour. For engineering, procurement, and construction (EPC) companies running these sites for clients rather than themselves, that juggling act multiplies across every project. Fusebox’s Energy Management System (EMS) exists to take it off your plate: more control, better margins, less daily hassle.

Raido Seppam, EMS Commercial Development Manager at Fusebox, hears the same story from almost every client:

“I’ve talked to hundreds of asset owners and EPC companies about their projects, and the pattern is always the same. You’re optimizing renewable output, trying to turn storage into a revenue stream, matching consumption to volatile prices, selling excess back to the grid, and staying under your connection limit the whole time. That’s a lot for one site. EPCs usually run several, often in different countries with different rules. Fusebox EMS was built to handle exactly that.”

How it actually works

Fusebox EMS connects your solar, batteries, and EV chargers into one system using standard protocols. No rip-and-replace, no separate dashboard for each asset type. Excess renewable output gets stored automatically instead of going to waste, which lowers your grid imports and lifts overall efficiency.

The battery does more than sit there as backup. It charges when prices are low, discharges when they spike, and turns into a real source of revenue. Onsite consumption shifts automatically to track real-time prices, and the whole site stays within its grid connection limit without anyone watching a dashboard for it.

Does it work across multiple sites?

Yes — the same platform and the same logic apply whether you’re managing one site or fifty. Each site runs under its own local rules and connection limits, but they’re all visible and controllable from one dashboard, so expanding to a new location or a new country doesn’t mean starting over with a separate system.

What this looks like in practice

One Estonian PV and battery site running on Fusebox EMS earned €31,258 in a single year from arbitrage alone, on top of its normal production revenue. Storing excess generation instead of curtailing it also lifted that site’s PV output by 17%.

The same automated, price-based dispatch is what keeps sites out of peak-hour tariff exposure and away from negative-price penalties in the first place.
