Electricity Storage System Installed at Inotal Plc.

An electricity storage system is being installed at the Várpalota site of aluminium semi-finished products manufacturer Inotal Plc. The HUF 3 billion investment, which will be financed with HUF 1.35 billion from EU funds and HUF 1.65 billion from the company's own resources, is expected to be completed by autumn this year, the plant's director, Tamás Németh told MTI on Friday.

He said that the plant in Várpalota, W Hungary, will be used to store the electricity generated by the factory's solar power plant and will supply the factory with energy.

A plant with a rated capacity of 10 megawatts (MW) and an energy storage capacity of 20 megawatt hours (MWh) will be built, which will be able to power the company for five hours.

Speaking about the importance of the energy storage facilities, he said that there is often a surplus of power on the electricity grid, especially on hot summer days. This surplus can cause disturbances in the control system, but if it can be fed into batteries, the surplus does not cause disturbances and the energy is conserved and used.

He added that Inotal Plc. will keep the installed energy storage system in operation for at least ten years after the project is completed, according to the grant contract, and the equipment can operate for 25 years.

Tamás Németh also said that the company manufactures semi-finished aluminum products, including wire, narrow strip for transformers and wire rod for wire rod.

In 2023, the company had a turnover of EUR 102 million, a net profit after tax of EUR 5 million and 284 employees. Its customers – more than a hundred – are companies producing industrial products, almost all of them from EU countries.

The company has been operating in Várpalota since 1952.
