Slovenské elektrárne a.s. (majority-owned by Slovakia's state utility holding, with EPH/Czech state stakes) operates the Čierny Váh pumped-storage plant, Slovakia's largest, on the "2.11 Modernisation of Pumped Hydroelectric Energy Storage in Čierny Váh" Project of Common Interest list. CINEA first funded feasibility studies for the project with a EUR 2.1 million grant in August 2025; the EUR 62.63 million grant allocated 28 January 2026 is the follow-on "works" grant, covering 34.3% of eligible construction costs to upgrade two of the plant's six units (TG1, TG2) to variable-speed turbines and to add an 80 MW / 160 MWh battery energy storage system, branded internally as the "SE Integrator" hybrid-hub project. Severity is set at 2/5: the quantum (EUR 62.6 million) is modest relative to large national industrial-subsidy or tariff actions in the register, and the measure is EU development-grant financing for shared grid-balancing infrastructure rather than a sector-targeted trade-control or protectionist subsidy.
