These technologies help balance the supply and demand of the national grid and improve the usability of intermittent renewable energy. As part of Hungary’s long-term strategy to rely primarily on nuclear and renewable energy, expanding BESS capacity is essential. The National Energy and Climate Plan targets 500 MW of BESS by 2026 and 1 GW by 2030, but high upfront costs and uncertain returns continue to hinder investments.

To accelerate the adoption of BESS, the Hungarian government has launched several targeted initiatives for various stakeholder groups, including programs for industrial developers such as Metároló. The latest step in accelerating BESS investments is the Jedlik Ányos Energy Program, which supports companies in building renewable generation and BESS capacities to boost energy autonomy and efficiency.

The current call for proposals under the program provides investment support for companies to install BESS and expand renewable generation capacity. By reducing reliance on grid electricity and imported energy, the Jedlik Ányos scheme promotes greater self-sufficiency and cost efficiency. Its flexible structure allows both companies with existing systems and those starting from scratch to tailor their projects, making it a key driver of corporate sustainability and competitiveness in Hungary’s evolving energy landscape.

The total funding available under the Program is HUF 50 billion, with HUF 25 bln earmarked specifically for micro-, small- and medium-sized enterprises, and is expected to support between 2,500 and 2,600 projects. Companies can apply for non-refundable investment support ranging from HUF 10 million to HUF 1 bln, covering up to 50% of eligible costs depending on company size.

Projects must be completed by Dec. 31, 2027, focus on self-consumption, and ensure that at least 75% of stored energy comes from directly connected renewable sources, with the BESS system reaching at least 20% of the associated renewable capacity. A five-year maintenance obligation applies, and proposals are evaluated based on environmental impact, energy efficiency, and use of recycled components.

Participating in the program presents a strategic opportunity for companies to significantly reduce operational costs and shield themselves from the volatility of energy prices. By investing in renewable energy generation and BESS, businesses can achieve long-term financial stability and reduce their dependence on the central electricity grid. Once the initial investment is recovered, companies benefit from predictable energy expenses and improved energy security, key factors in maintaining stable operations in an increasingly unpredictable global market.

Beyond the financial advantages, BESS technologies enhance supply reliability and grid stability, which are becoming critical in a climate-conscious economy. From a sustainability standpoint, aligning with EU and national targets to increase the share of renewables in electricity production is not only a regulatory expectation but also a competitive edge. Companies that demonstrate a commitment to green energy are more likely to receive favorable consideration in future funding rounds and enjoy stronger public and market perception.

However, while the program offers attractive financing conditions, navigating its technical, regulatory, and contractual requirements can be complex. This is where expert legal advice becomes essential. As a leading law firm with experience in energy and infrastructure projects, we support clients throughout the entire process, from assessing eligibility and structuring applications to ensuring compliance and managing long-term obligations. In a rapidly evolving energy landscape, strategic investments in BESS and renewables, backed by sound legal guidance, can position companies for sustainable growth, operational resilience, and enhanced market competitiveness.
