Romania’s National Energy Regulatory Authority (ANRE) has taken aim at accelerating energy storage solution deployment by eliminating the double taxation on stored electricity.

This regulatory adjustment, announced on July 8, targets a previous financial barrier that required both charging and discharging to face tariffs.

Under the new ‘Order on the Methodological Norms’, electricity charged from the grid and subsequently discharged back onto it is exempt from several key regulated tariffs in the country.

The following changes were announced by ANRE, via translation:

What the regulation provides:
Exemption from payment of transmission tariffs (extraction component), distribution and system services for electricity stored and reintroduced into the grid;
Exemption from paying green certificates;
Introducing clear reporting obligations on the quantities of energy stored by network operators;
Implementation of a unified procedure, applicable to both concessionaire and non-concessionaire operators.

The exemption applies strictly to energy stored and reinjected into the grid. The ANRE Order notes that electricity consumed for a storage facility’s own operation, including technological losses during the charge-discharge process, will still be subject to standard grid tariffs. In other words, tariffs remain in place on self-consumption.

Still, the measure aims to dramatically enhance the profitability of storage projects and support the integration of renewable energy sources into the grid, while appealing to investors.

ANRE President George Niculescu stated, “We cannot build a balanced and resilient energy system with rules that penalise innovation. Through this regulation, we send a clear signal to investors: Romania supports energy storage, not just as a technological option, but as a pillar of the energy transition.”

Romania plans to add 5 GW of battery storage capacity by the end of 2026. Before this change, one analyst already saw a promising environment in the country, and Romania’s energy minister Sebastian Burduja said back in April this year that the country has increased its battery capacity to almost 400 MWh.
