Energy ministry official says Moldova develops energy storage capacities for more balanced, sustainable energy system

State Secretary of the Ministry of Energy Constantin Borosan, at the EU4Energy Policy Forum in Copenhagen, has unveiled the vision of Moldova regarding the development of a sustainable energy system, with a focus on increasing energy storage capacities and integrating renewable sources.

According to the official, Moldelectrica, the electricity transmission system operator, by late last May issued connection permits for private energy storage projects with a total capacity of 83 MW. These are initiatives that include also photovoltaic parks and are set to be completed by October 2026.

Borosan also said the initial project funded by United States Agency for International Development (USAID), which envisaged the installation of 75 MW batteries and 22 MW internal combustion engines, a project that was however canceled. Presently, alternative funding sources are sought for its implementation.

At the same time, the authorities plan to set thermal energy storage tanks, which could provide approximately 1,200 MWh of thermal energy in Chisinau and 240 MWh in Balti, thereby contributing to the diversification and stabilization of supply networks.

The state secretary noted that the increasing integration of renewable energy into the national energy system – energy that depends on weather conditions and is intermittent – needed the development of network balancing mechanisms, either through storage or quick generation sources.

In the last five years, the installed capacity of wind and photovoltaic power plants   has increased eightfold in Moldova, reaching 665 MW, and the share of green energy in national consumption has risen from 3 per cent to an annual average of 16.7% in 2024. In April 2025, over 36 per cent of the energy consumed in the country came from renewable sources.

The participants in the Danish forum, organized by the International Energy Agency (IEA), discussed innovative energy storage solutions, including hydro options, green hydrogen-based solutions and thermal storage systems. They visited a modern thermal energy storage station, combined with solar technology, which supplies centralized heating systems in two Danish settlements.
