Finnish utility to deploy 90MW storage system with Hitachi ABB Power Grids

0

Finnish nuclear power company Teollisuuden Voima (TVO) has selected Hitachi ABB Power Grids for the provision and installation of what is claimed to be one of Europe’s largest battery energy storage projects.

The 90MW battery energy storage plant will be installed on the island of Olkiluoto where TVO will be building its third nuclear power plant.

The energy storage project will help ensure grid reliability on the entire grid by minimising power fluctuations during the construction of the nuclear unit. Once the third nuclear power plant is commissioned, up to 30% of Finland’s total electricity will come from the island. The project is expected to play a key role in enabling Finland’s energy transition and the achievement of their carbon-neutrality goals.

Matti Vaattovaara, Country Managing Director of Hitachi ABB Power Grids’ business in Finland, said: “By 2050, electricity will be the backbone of the entire energy system.

“The energy revolution requires pioneering technologies and new intelligent solutions to ensure system flexibility and reliability. Battery energy storage of this scale, and the growth in low emission electricity production, represent significant steps for the climate and contributes to Finland’s goal of carbon-neutrality in 2035.”

Sami Jakonen, technical director at Teollisuuden Voima added: “TVO’s contribution to national electricity production is growing, and the soon-to-be completed Olkiluoto 3 plant unit is a critical part of this effort.

“With this investment in battery energy storage, we are helping to ensure uninterrupted electricity supply in Finland. In the event of a disturbance in production, battery energy storage is used as backup power until an alternative production method is generating electricity. In this way, we ensure the reliable operation of the grid even in a situation in which a large amount of electricity would otherwise fall out of the grid capacity.”

The battery energy storage system will be commissioned in 2022.
