Luxcara has acquired the 125 MW Tuisku BESS project in Finland, pushing its battery storage capacity under construction to nearly 1 GW. The asset is fully permitted, holds a binding grid connection with Fingrid, and targets COD in summer 2027. A long-term tolling agreement underpins revenues.

The insight is simple: this is a merchant storage market, but the capital stack is being structured like infrastructure.

Finland’s power system is increasingly wind-heavy and volatile. That creates arbitrage upside. But Luxcara did not buy volatility alone. It secured grid access next to a 400 kV substation, advanced development status, and a contracted tolling structure to stabilise cash flows.

Execution risk is largely removed. Land rights are secured. Grid works are underway. Construction is scheduled. That compresses development risk and supports leverage.

Commercially, this signals where European BESS is heading. Institutional capital will fund large-scale batteries in volatile markets — but only when revenue visibility and grid certainty are locked in. Tolling is becoming the bridge between merchant upside and infrastructure-grade returns.

Scale plus structure is the strategy.
