The newly opened factory began operations with an impressive annual production capacity of 3 gigawatt-hours (GWh), which is planned to be expanded to 5 GWh by the end of 2026. In addition, a second, fully automated production facility is currently in the design and planning phase, and when completed, it will bring the total production capacity of the company to a remarkable 15 GWh by the end of 2027. This significant increase in production capability would position Bulgaria as a key manufacturer, enabling the country to supply up to 15% of Europe’s anticipated demand for battery energy storage systems, thereby reinforcing its role in the continent’s energy infrastructure.

“It is time to stop underestimating the Bulgarian industry and make it more visible so that we can feel proud of it. The power of electricity is important, but so is human power.” This was stated by Deputy Prime Minister and Minister of Innovation and Growth Tomislav Donchev during the opening of a new high-tech factory for battery energy storage systems. It is located in the Hemus Industrial Park in Chelopechene. Donchev emphasized that it is precisely for such new production facilities that highly qualified workers and more engineers are needed.

The scale and significance of this investment are strategic not only for Bulgaria, but also for Europe as a whole. The newly launched EXERON X-BESS represents a next-generation battery energy storage system, meticulously engineered to meet the rapidly growing demand for flexible and reliable solutions aimed at stabilizing the electricity grid. It also ensures the security of energy supply, especially as the share of renewable energy sources within the electricity system continues to rise. The introduction of this innovative technology positions International Power Supply AD (IPS) as a leading force driving the energy transformation across Europe, setting new standards for efficiency, sustainability, and reliability.

This investment received official recognition as a strategic production capacity for net-zero emission technologies in June of this year. As a result, Bulgaria has been placed among the select group of countries that are now playing a key and influential role in the European, as well as global, transition to clean and sustainable energy sources. This acknowledgment underscores Bulgaria’s commitment to contributing to the worldwide efforts to combat climate change and achieve ambitious environmental targets.

This major investment will make a substantial contribution to Europe’s energy security, industrial resilience, and the development of a robust entrepreneurial ecosystem. With the commissioning of the new factory, the company is strategically positioning Bulgaria on the European map of clean technologies. Additionally, the investment is paving the way for the emergence of a new industrial sector within the country, one with considerable potential to generate highly skilled employment opportunities, advance professional skills, foster innovation, and facilitate the export of cutting-edge technologies to international markets.

The inauguration event held at the industrial park in Chelopechene attracted a distinguished group of attendees, including Sofia Mayor Vasil Terziev, former President Rosen Plevneliev, prominent representatives from IPS management, as well as delegates from both local and international energy companies. Industry organizations and other key stakeholders were also present, underscoring the importance and wide-reaching impact of this new factory within the Bulgarian and European energy landscape.

International Power Supply AD (IPS) is a renowned Bulgarian energy technology company, distinguished by its extensive experience spanning many years in research and development, engineering, and the manufacturing of comprehensive solutions. IPS’s expertise covers industrial power supply systems, microgrid technologies, and advanced energy storage systems, all designed to meet the evolving needs of modern infrastructure and support the transition towards more sustainable energy practices.

The EXERON platform, which serves as the foundation for the latest advancements in industrial battery energy storage systems, stands out as one of the pioneering technological solutions in the field. It enables the seamless integration of energy storage from renewable energy sources and facilitates the construction of advanced microgrids. These microgrids provide uninterruptible power supply to critical infrastructure facilities across a variety of sectors, including energy, telecommunications, defense, and many others. The platform’s innovative design and versatility make it a vital asset in the ongoing shift towards sustainable and resilient energy systems.

The Bulgarian solar power market has been experiencing significant growth since 2021. As a result of the high economic growth in the last 3 years, industrialisation and urbanisation, the demand for new energy generation sources to replace the coal-based power plants in Bulgaria is increasing. By the end of 2024, Bulgaria had a cumulative installed solar capacity of 4,568 MW (4.57 GW), representing an increase of 1,283 MW (1.28 GW) compared to 2023.

For the first half of 2025, almost 450 MW (0.45 GW) of new solar power capacity has been installed in the country, and the cumulative capacity is currently close to 5,000 MW (5 GW).

In 2023, for the first time, Bulgaria joined the group of European countries that installed more than 1 GW of new capacity in a single year. Several large-scale solar photovoltaic (PV) projects with a power capacity above 100 MW were launched into commercial operation in Bulgaria between 2021 and 2024. The utility-scale sector dominates the installed solar capacity, with a share of 77%.

The battery energy storage system (BESS) market in Bulgaria will experience robust growth by 2030 in the co-located/behind-the-meter (BTM) and front-of-the-meter (FTM) segments. Together with the already approved at the end of April 2025, 82 projects for the construction of batteries for the storage of electricity under the Recovery and Sustainability Plan for nearly BGN 1.2 billion (€ 600 million), awaiting the signing of contracts, and 30 reserve projects for which additional money is still being sought through the new chapter of the plan – RePowerEU, Bulgaria intends to become a balancing force in the region.

By the end of 2027, Bulgaria is expected to install between 7 GWh and 11 GWh of new battery energy storage systems, according to the Central East and South East Europe Battery Energy Storage System (BESS) Market Outlook 2025 ÷ 2034.
