Koncar Elektorindustrija, a Croatian electrical company, announced that its joint venture with Siemens Energy, Koncar - Power Transformers has successfully completed the testing of the first of two 120 MVA, 380 kV transformers. The tests, finalized in October 2024, were engineered to aid grid stabilisation, supporting bidirectional energy transfer between battery systems and the power grid.
The first transformer is set for installation in northern Germany’s battery system, while the second unit, currently under production, will be deployed in southern Germany. These pilot projects are part of a larger initiative by Germany’s four transmission system operators to optimize the Ultrastack battery system and enhance grid capacity, especially addressing challenges associated with the north-south transmission of wind power.
With a total capacity of 700 MW, these projects are key components in Germany's plan to reach 54.5 GW by 2045, as part of efforts to meet the country's projected electricity consumption of 1,303 TWh by mid-century.
The Koncar-Siemens JV transformers meet stringent noise limits of 80 dB under nominal load and are designed with added acoustic shielding to minimize sound pollution. Enhanced safety and maintenance features ensure worker protection and operational efficiency.
