What is the largest battery energy storage system in Sweden?

Named Isbillen Power Reserve, the 1-hour duration Battery Energy Storage System project will be the largest in Sweden and the largest in the Nordics by megawatt (MW) power. The largest by megawatt-hours energy capacity in the Nordics will be a 2-hour project in Finland that Neoen recently started building.

How many large-scale energy storage systems are there in Sweden?

The initiative, led by Ingrid Capacity in collaboration with BW ESS, consists of 14 large-scale energy storage systems with a total capacity of 211 MW/211 MWh. This milestone investment represents a significant step toward Sweden’s goal of achieving a carbon-neutral energy system.

Who is responsible for Sweden's energy grid connection?

At the time, Sweden's Minister of Climate and Environment, Romina Pourmokhtari, was responsible for overseeing the grid connection. In comments at the ceremony, Pourmokhtari said, ‘It is a great honour to launch the largest investment in energy storage in the Nordics, with 211 MW of electricity currently connected to the grid.

When will a battery energy storage system be built in Sweden?

Construction has begun on Sweden’s largest Battery Energy Storage System (BESS) undertaken by Neoen, an Independent Power Producer and Nidec, a system integrator. The project has been projected to come online in early 2025. Neoen is headquartered in Paris.
