Neoen’s Storen Power Reserve begins construction in Sweden

Notice to Proceed given to Nidec at the end of December 2022, French renewable energy producer says

Neoen, the French producer of exclusively renewable energy, has said that it had provided the Notice to Proceed to Nidec, the battery storage expert, at the end of December 2022, signalling the start of construction of the Storen Power Reserve in Sweden.

In a statement, Neonen said that the 40MW/40MWh lithium-ion battery will be located in the municipality of Ragunda, which is approximately 100 kilometres from the city of Östersund. Scheduled to be operational by the first half of 2024, the facility will be connected to the 130kV E.ON grid, the company added.

Laetitia Prot, Head of Business Development Sweden, Neoen, said: “We are delighted to see Neoen expanding fast in Sweden, only two years after setting up our team in Stockholm. I wish to thank all stakeholders, in particular distribution system operator E.ON, and Ragunda Municipality, for their support, and for playing alongside us an active role in Sweden’s energy transition. 

“Storen Power Reserve is a perfect demonstration of our unique expertise, which enables us to roll out innovative solutions rapidly. We will continue contributing actively to the development of renewable energy in Sweden in 2023.”

In line with its develop-to-own model, Neoen will own 100% of Storen Power Reserve and will be the long-term operator of the asset. The battery will provide Svenska Kraftnät, the Swedish transmission system operator, with ancillary services – and more precisely Frequency Containment Reserve services. 

Furthermore, it will help maintain the balance between production and consumption in real time, efficiently enhancing the power system security, the statement explained. The battery will reduce grid stabilisation costs while facilitating the integration of renewable energy assets.

Major Player

The launch of the asset reflects Neoen’s ambition to become a major player in Sweden, the company said. In addition to the 40 MW / 40 MWh Storen Power Reserve battery, Neoen’s Swedish assets include the 57.4MW Storbrännkullen wind farm, which is currently under construction, and the 90MWp Hultsfred solar park, which is planned for construction in the second half of 2023. 

Based in Stockholm since 2020, Neoen’s fast-growing Swedish team is developing numerous projects across the country. The Storen Power Reserve is Neoen’s second battery in the Nordics, the first being the 30 MW / 30 MWh Yllikkälä Power Reserve in Finland, which has been in operation since 2020. 

Xavier Barbaro, Neoen’s Chairman and Chief Executive Officer, stated: “I would like to congratulate our Swedish team for this major milestone. We are convinced that large-scale battery storage is vital to the energy transition in Sweden, as in the rest of the world. 

“Storage is the key to unlocking the full potential of solar and wind. Through our solar, wind and storage assets in Sweden and elsewhere, we are proud of our leading role in establishing the power generation mix of the 21st century.” 

The firm is a leading owner and operator of big batteries, with a battery storage portfolio of over 1,000 MW in operation or under construction. In particular, Neoen owns and operates two of the world’s largest batteries: the 300 MW / 450 MWh Victorian Big Battery, and the 150 MW / 193.5 MWh Hornsdale Power Reserve, both in Australia.
