As of the end of 2024, the share of RES-E in Slovakia's electricity generation increased by a percentage point compared to the previous year, reaching 24.2%. Hydropower continues to lead, comprising 66% of the total installed renewable capacity, followed by solar PV at 29% and bioenergy at 5%.
For the second consecutive year, Slovakia has witnessed notable acceleration in the solar PV sector. This growth has been primarily driven by the declining cost of solar technology, coupled with relatively high energy prices faced by businesses, which has increased interest in PV systems.
In late 2023, the Slovak Battery Alliance (SBaA) estimated the total capacity of stand-alone BESS in Slovakia to be 27.5 MWh. This section aims to provide the most accurate estimate of battery storage market developments across all sectors in 2024.
SAPI's annual Outlook provides a quantitative description of the Slovak electricity market, focusing on five renewable energy technologies (RES-E) with potential and a foreseen role in the national energy market.
Biomass currently dominates electricity generation from renewables, followed by biogas, solar, and hydropower. Despite its high potential, wind energy remains largely untapped in Slovakia due to its perceived instability and regulatory hurdles.
In its future projections, the Slovak electricity TSO SEPS anticipates around 700 MW (with an estimated capacity of approx. 1,400 MWh) of BESS in operation by 2040. This is expected to increase gradually from 5 MW installed in 2022, reaching 260 MW by 2030 and 468 MW by 2035.
