Axpo, a leading international energy company, has announced plans to develop one of the largest battery energy storage facilities in Sweden. The project, acquired from project developer SENS (Sustainable Energy Solutions Sweden), aims to provide essential ancillary services to balance the power grid. Construction of the facility, located in the town of Filipstad, about 300 km west of Stockholm, is expected to begin in early 2024.

Axpo pushes the boundaries of sustainability with battery energy storage project and solar power plant

The heart of this ambitious undertaking is a 25 MW lithium-ion battery energy storage system. Designed to support the electrical grid, the battery energy storage facility will play a vital role in providing ancillary services. Axpo’s commitment to renewable energy and sustainable solutions is also illustrated by the simultaneous development of a ground-mounted solar power plant in Filipstad. With a projected capacity of up to 20 MW, this solar power plant will complement the battery energy storage facility, covering an extended area of over 23 hectares (230,000 m²).

Axpo’s acquisition of these projects from SENS marks an important step in their drive to advance the energy mix of the future. The collaboration between Axpo and SENS will ensure the successful development of both the battery energy storage system and the solar power plant. While the commercial terms of the transaction are not disclosed, both parties are excited about the opportunities ahead.

Axpo and SENS: Strategic alliance for innovative energy solutions

Frank Amend, head of batteries and hybrid systems at Axpo Group, expressed his excitement about the acquisition, saying, “We are acquiring two important projects from SENS, which we will develop together with them. Battery energy storage systems and solar energy are becoming increasingly important in the energy mix of the future, and we look forward to continuing our cooperation with our colleagues at SENS.”

SENS CEO Henrik Boman echoed Amend’s sentiments and emphasized the importance of the partnership with Axpo. Boman said, “We are delighted to partner with Axpo, a leading international energy provider that is truly at the forefront of the energy transition in Europe. This project will be one of the largest solar and battery energy storage parks in Sweden, and we are very proud to work with such a respected and experienced partner. We will work closely together to ensure the success of the project and see great potential for future collaborations with Axpo.”

Axpo’s involvement in the development, construction and commercial optimization of large-scale battery energy storage solutions underlines its expertise in this field. With the goal of achieving substantial storage capacity in Europe by 2030, the company is leveraging its extensive knowledge of international energy trading to effectively market and maximize the use of battery energy storage facilities in ancillary services and energy trading.

Axpo has been active in Sweden since 2005 and has established itself as a key player in the country’s energy sector. Through its innovative projects and collaborative efforts, Axpo continues to promote the energy transition and contribute to a sustainable future in Sweden. The development of the battery energy storage facility and the ground-mounted solar power plant in Filipstad represents a significant step towards achieving a greener, more resilient electricity grid.
