Romania has taken a decisive regulatory step in favor of its clean energy transition, removing the double taxation that hindered the development of battery energy storage systems. The Romanian Energy Regulatory Authority (ANRE) has adopted new methodological norms that exempt stored and reinjected electricity from several key charges, addressing a long-standing obstacle for market growth.
This regulatory change directly targets one of the main financial bottlenecks for investors, enhancing the profitability of storage projects and supporting the integration of renewable energy into the grid with greater flexibility and resilience.
Under the new regulation, stored energy that is reinjected into the grid will be exempt from transmission (withdrawal component), distribution tariffs, and system services charges. In addition, green certificate payments will also be waived, significantly lowering operational costs.
“We cannot build a balanced and resilient energy system with rules that penalize innovation,” states ANRE in its official release. “This regulation sends a clear signal to investors: Romania supports energy storage not only as a technological option, but as a central pillar of the energy transition.”
The framework also introduces standardized procedures applicable to both concessionary and non-concessionary grid operators, and mandates clear reporting obligations for energy storage volumes. This contributes to greater market transparency and predictability, elements highly valued by developers and financiers alike.
It is important to note that the exemption applies strictly to energy stored and reinjected into the grid. Electricity consumed for internal use or losses in the storage process will still be subject to standard grid charges.
From the private sector, the Romanian Photovoltaic Industry Association (RPIA) has welcomed the new rules, recognizing the decision as the result of sustained dialogue with key stakeholders. “RPIA supports the development of a balanced clean energy framework, and this regulatory progress is a meaningful step forward,” the association affirms.
The regulation aligns Romania with best practices across the European Union and the recommendations of ACER, which advocate for differentiated tariff structures and flexibility-oriented incentives.
With this move, Romania joins a growing group of countries that use regulatory mechanisms to actively support energy storage, acknowledging its strategic role in decarbonizing the power system and ensuring grid reliability.
By continuing the path laid out by Emergency Ordinance No. 134/2024, this measure helps consolidate a coherent and predictable legal framework that encourages long-term investments in clean energy infrastructure.
Ultimately, this is not just a regulatory adjustment—it is a market signal. Romania is now positioning energy storage as an essential component of its modern energy landscape, advancing toward a smarter, greener, and more resilient power system.
