Projects on markets partnering with top-class Balance Responsible businesses delivering end-to-end BESS systems, grid connection expertise, and strategic consulting for resilient commercial and industrial energy solutions.
STS = source transfer switch: your site moves to backup power automatically when the grid drops.

Market access delivered through aggregation of multiple assets (battery packs), thereby generating revenue for asset owner.
In case of an outage: Prepare your STS ensuring autonomous power in milliseconds — keeping ventilation, feeding and cooling systems running.
Monetize asset flexibility: market access for TSO/DSO Ancillary Services for large-scale systems.
Defined by ENTSO-E/NORDEL.
Island mode for households: continuous operation of fridges/freezers and essential loads during extended outages.
Drag the slider: a normal day across Europe, and the same map in a blackout.
Every region is supplied. A grid-connected battery earns from the market in the background.
Whole regions lose supply, as in the blackouts that hit Spain and Italy. Sites without backup stop. Sites with a battery and STS keep their critical loads running.
Would your site keep running? The STS switches critical loads to the battery when the grid drops.
Prepare my site for an outageA single battery pack is too small to take part in the grid-stabilization markets on its own. We aggregate many packs into one pool that can act as a single resource.
Market access is delivered through aggregation of multiple assets (battery packs), thereby generating income for the asset owners.
Rugged, modular BESS enclosures designed for Nordic climate [C5]. Scalable capacity, Easy to install, Fast grid connection, positive-listed products, and remote monitoring, control, and diagnostics.

Clear steps from discovery to long-term support.
One accountable partner from the first estimate to a running plant: advisory, sizing, installation, and operations with market access.
The things worth knowing before you invest.
It depends on capacity (kWh) and power (kW). Where a standard pack has a price, it is shown in the product table; for anything else you get a written case with the actual figure before anything is ordered.
Grid connection and DSO liaison are part of the delivery, so you do not coordinate it yourself. Your main fuse size is one of the first things checked because it shapes the whole case.
STS is the source transfer switch. When the grid fails it moves your critical loads onto the battery, for example ventilation, feeding and cooling on a farm.
Where it fits, battery packs are aggregated into one pool that can take part in energy markets, and the income goes to the asset owners. The screening shows what is realistic for your site.
Then we say so and you do not build yet. The recommendation rests on your own consumption data.
