Greenvolt commissions large-scale BESS in Hungary

Greenvolt opened a grid-scale BESS facility in Hungary on 11 June 2026, according to Renews.biz. No MW or MWh figure was available in the headline, but the project is described as a "giant", suggesting it ranks among Hungary's largest storage assets to date.

The timing sits alongside a broader structural shift in the region. Modo Energy reports that Poland's BESS investment case is rotating away from capacity-market contracts toward merchant revenue stacking, a sign that ancillary-service and wholesale spreads are now expected to carry more of the return. That transition mirrors a pattern already visible in GB and Germany, where capacity revenues alone no longer close the business case.

Aurora Energy Research published its European Battery Market Attractiveness Report (BATMAR 26) in February 2026, covering relative country rankings across the continent. Detailed scores were not available in the public summary, but the report's release underscores growing institutional focus on CEE markets as the next deployment frontier.
