MVM Firm Builds New Grid Energy Storage Facility

MVM Green Generation Plc., a renewable energy company of the MVM Group, is installing a 20 megawatt-hour electricity storage facility in Sopronkövesd, NW Hungary next to its owned and operated wind farm, with a capacity of 20 megawatt-hours of electricity, MVM Green Generation Plc. informed MTI on Tuesday.

Hungary's Recovery and Resilience Plan provides HUF 1.35 billion in non-reimbursable aid for the investment, financed by the European Union under the program entitled Installation of Network Energy Storage Facilities by Energy Market Operators.

The 10-megawatt lithium-ion battery with a nominal capacity of 20 megawatt-hours will be installed in the vicinity of the Sopronkövesd-Nagylózs wind farm in the municipality of Sopronkövesd.

Within the site to be developed, 22-kilovolt underground cables and a new 22-kilovolt substation will be installed, with grid connection at the existing 132/22-kilovolt transformer station serving the wind farm.

The so-called co-location connection, the sharing of existing connection points and capacities, is an innovative solution that will help to make more efficient use of the capacity of the electricity system and to integrate weather-dependent renewable energy sources to a greater extent.

The ultimate objective of the project is to increase the integration of weather-dependent renewable energy producers into the system and to increase the flexibility of the electricity system. The deployment of grid energy storage will contribute to the achievement of domestic targets in line with the European Union's 2030 climate targets and climate neutrality 2050. It will help reduce greenhouse gas emissions by eliminating the need to re-produce electricity that is surplus and stored at a given moment, or to keep in operation the regulatory capacity to regulate it, the statement said.
