Large-scale battery projects are becoming an increasingly important component of Romania’s energy system. According to Transelectrica, the country had 599 MW of installed energy storage capacity, corresponding to 1,129.7 MWh, as of 1 April 2026.
As battery storage develops, its role is expanding from supporting the wider power system to helping businesses manage their energy consumption more effectively. This evolution is reflected across the Greenvolt Group, which has around 5 GW of BESS projects in its utility-scale pipeline globally – including 209 MW in Romania – while the technology is also gaining traction among commercial and industrial companies, as seen in the growing activity of Greenvolt Next, the Group’s business dedicated to this segment.
For these customers, the rationale goes beyond simply storing surplus solar generation. As energy markets become more volatile, companies are placing greater value on having more control over when they produce, store and consume energy. For industrial customers in particular, with high energy demand or variable consumption profiles, battery storage can help increase self-consumption, reduce peak electricity demand and give companies greater flexibility in managing their energy costs.
The shift is already reflected in Greenvolt Next’s activity across Europe. Since the beginning of 2026, the company has contracted more than 100 MWh of projects incorporating battery storage, with Romania among the markets where demand is gaining momentum.
Gino Gauthier, CEO, Distributed Generation Business, Greenvolt Group, said, “Across Europe, we are seeing growing demand for behind-the-meter battery storage, and we are beginning to see the same trend in Romania. Given the profile of the country’s commercial and industrial sector, we believe battery storage can become a significant growth area in the B2B market. Adding batteries to on-site solar is a logical step in managing energy more intelligently and deciding not only how much energy is produced, but when it is used and when the grid is needed. For companies, this means more control and a greater ability to reduce and manage energy costs.”
Filipe Dias, Country Manager of Greenvolt Next Romania, said, “The Romanian market is maturing, and this is also reflected in the way companies are increasingly looking beyond solar generation alone to manage their energy more efficiently. For industrial and commercial companies, particularly those with high and predictable energy consumption, adding battery storage can significantly lower energy costs and improve energy efficiency. With our PPA model, we can bring these solutions to businesses without requiring upfront investment from the customer, making it easier for more companies to act on this opportunity.”
The improving economics of the technology are another important factor behind this acceleration. Battery costs have fallen by around 40–50% in recent years, making storage increasingly viable across a broader range of consumption profiles and use cases.
Demand is also extending beyond new solar installations. Greenvolt Next is seeing more companies with existing photovoltaic systems add battery storage to optimise the energy they already produce. This points to a maturing market, as companies move beyond simply generating renewable energy towards managing it more intelligently.
