European battery storage sees growth in Netherlands, Belgium and Spain

The large‑scale battery storage market in Europe is expanding, with contrasting profitability dynamics in the Netherlands and Belgium. In Belgium, a ten‑year exemption from certain grid‑access tariffs and an established capacity market provide strong revenue streams, making the country one of the most attractive for investors. The Netherlands, while benefiting from high renewable penetration and grid congestion, faces higher connection costs that can lower internal rates of return by five to ten percentage points. Both markets are shifting from reliance on ancillary grid‑service revenues to energy‑price arbitrage, with four‑hour battery configurations identified as the most economically viable.

In parallel, Nuveen Infrastructure and solar‑inverter maker Sungrow have signed a framework agreement for 1.32 GWh of storage capacity. The deal will supply 302 PowerTitan 2.0 systems and 77 medium‑voltage cells to Nuveen’s European renewable‑energy portfolio, targeting key southern‑European markets such as Spain and Italy. It includes a long‑term service contract guaranteeing 98 % system availability and 24/7 operational support. As Javier Izcue of Sungrow Europe said, “this agreement framework … represents an important step to accelerate the deployment of storage in Europe.” Together, these developments illustrate accelerating deployment of utility‑scale battery storage across the continent.
