Slovenia operates a tightly-balanced mix: the Krško nuclear plant (co-owned with Croatia) delivers around 35% of generation, hydropower from the Sava and Soča rivers adds ~28%, and lignite from the Šoštanj and Velenje basins still provides ~25%. ELES, the national TSO, runs the SI bidding zone and is co-shareholder in BSP Southpool, the regional day-ahead exchange. Slovenia is electrically coupled to Italy, Austria, Croatia and Hungary, making it a critical north-south transit corridor for the Continental European grid.
The Krško-2 expansion — a single new unit of either AP1000 or APR1400 design — is scheduled for a binding 2027 referendum and would target commercial operation in 2038. Solar capacity tripled between 2022 and 2025 to over 1 GW, with strong residential rooftop adoption following the 2023 net-metering reform.
The Šoštanj coal plant runs until 2033 under a court-ordered phase-out.
