Hungary's MOL Commissions 37.4MW Solar and 40MWh Energy Storage Project

en.Wedoany.com Reported - On September 18, Hungary's MOL Group announced the official commissioning of a newly built 37.4MWp solar power plant and its accompanying battery energy storage system at its Algyő site. The energy storage system has a rated power of 20MW and a capacity of 40MWh. Following commissioning, the project operates alongside Algyő's existing power facilities and can cover the entire electricity demand of MOL's local operations.

The solar plant's annual power generation is equivalent to the annual electricity consumption of approximately 22,500 households in Csongrád-Csanád County. The accompanying energy storage system is used to smooth out power fluctuations caused by intermittent renewable energy sources such as solar, and can feed electricity back to the grid when needed. MOL estimates that the new project can reduce carbon dioxide emissions by approximately 13,000 tonnes per year.

The solar plant in the project was built by ALTEO Plc., which may also take on aggregation services after the project's completion. MOL and its partners currently hold a combined 73.8% stake in ALTEO. ALTEO currently operates approximately 115MW of renewable energy generation assets, including wind, solar, hydro and biogas.

The Algyő project had already entered the construction phase in 2025. MOL disclosed at the time that it would build a 37.4MWp solar plant and a 40MWh energy storage system at the site to enhance the electricity self-sufficiency of local facilities and reduce purchased electricity. MOL's 2026 investor materials show that the solar project has been included in the group's renewable energy asset portfolio delivered that year.

With the commissioning of the Algyő project, the number of solar plants operated by MOL in Hungary has increased to 9, with total installed capacity reaching 405MW; the group's two energy storage facilities operating in Hungary have a total capacity of 80MWh. Under its existing plans, MOL aims to deploy a total of 500MWh of energy storage capacity in Hungary by 2030. The group also operates two solar plants with a combined 10MW in Croatia and plans to add a new project in 2027, increasing local solar capacity to 23MW.

MOL's total installed solar capacity in the Central and Eastern Europe region has now reached 415MWp. With the commissioning of the Algyő project, the group's existing regional solar assets are expected to reduce carbon dioxide emissions by approximately 160,000 tonnes per year in total.
