Hungary is taking a significant leap forward in its renewable energy sector with the launch of four new solar energy storage projects by Alteo, a Budapest-based renewable energy company. These projects, part of an impressive 2024 growth essential to the nation’s energy strategy, have a combined capacity of 90 megawatts and are set to significantly enhance the country’s energy grid and support the seamless integration of renewable energy sources.
New Hungary solar energy storage Projects
Alteo has connected four new energy storage units to Hungary’s electricity grid, boosting the country’s solar power capabilities. These units, located in Dunaharaszti, Balassagyarmat, Törökszentmiklós, and Nagykeresztúr, have a total power capacity of 90 megawatts (MW) and a storage capacity of 193 megawatt-hours (MWh).
The first unit in Dunaharaszti has already begun operations, with the remaining three set to follow shortly. These projects are part of Hungary’s broader efforts to transition to renewable energy and reduce its reliance on fossil fuels, a move critical for national energy security. The trend is clear, as other developers like Photon Energy have also expanded Hungary’s solar PV capacity with new plants, showing a robust and growing market.
The energy storage units are co-located with photovoltaic (PV) power plants, which use solar panels to convert sunlight into electricity. The intricate solar panel manufacturing process transforms basic solar panel raw materials into the high-tech devices that power these plants. The addition of battery storage technology is crucial for managing the intermittent nature of solar power, allowing excess energy generated during sunny periods to be stored and released when demand is high or the sun isn’t shining.
Government Support for Renewable Energy in Hungary solar energy storage
The Hungarian government has been actively supporting the development of renewable energy projects through various financial incentives. In 2020, Alteo received a HUF 1.2 billion grant from the Ministry of Innovation and Technology to develop its energy storage projects. This funding has been crucial in enabling Alteo to expand its renewable energy portfolio and contribute to the country’s energy transition.
The company has also secured long-term power purchase agreements (PPAs) with major industrial consumers, providing it with a stable revenue stream. These agreements ensure that the electricity generated by Alteo’s solar power plants is sold at a fixed price over a specified period, reducing investment risk and making it easier for the company to plan and finance its projects.
In addition to the government’s financial support, Alteo has raised funds through a successful initial public offering (IPO) on the Budapest Stock Exchange. The company raised HUF 4.5 billion through the IPO, which has been used to finance its renewable energy projects, including these new energy storage units.
Benefits of Energy Storage for Hungary solar energy
Energy storage is a vital component of a modern, renewables-heavy power system. It allows for the storage of excess energy generated during peak sunlight hours, which can then be used during periods of low sunlight or at night. This helps to balance supply and demand, ensuring a stable and reliable electricity supply. A unique 2024 deal for a solar battery system elsewhere in the country underscores the growing recognition of storage as a key grid-stabilizing technology.
The storage units will help integrate more renewable energy into Hungary’s grid. As the country continues to increase its share of renewables, the need for energy storage solutions will grow. These systems allow for the smooth integration of variable sources like solar and wind, reducing the risk of blackouts. For residents across Europe, including in Germany, a more stable and interconnected European grid means greater energy security and potentially more stable long-term energy prices.
These new projects will have a significant impact on Hungary’s renewable energy sector. The country is on track to not just meet but surpass 8 GW in solar power capacity by mid-2025, and these new energy storage units will play a crucial role in managing this impressive capacity and achieving an impressive 30% share of solar energy in its electricity mix.
The new solar energy storage projects by Alteo represent a significant step forward for Hungary’s renewable energy sector. With strong government support and innovative technology, these projects are expected to enhance the country’s energy security and contribute to its ambitious goal of achieving carbon neutrality by 2050.
