Paper product company Arctic Paper has tied up with developer S.E.R to deploy BESS projects for ancillary services totalling 24MW at two of its factories in Sweden, with plans to do something similar in Poland.

Arctic Paper has signed a 15-year agreement with S.E.R Sverige to provide space and grid connections at its Grycksbo and Munkedals paper mills for battery energy storage system (BESS) projects. The two projects will total 24MW of capacity and will help the sites provide system services to the transmission system operator (TSO) of Sweden, Svenska Kraftnät.

The Grycksbo paper mill has already been providing system services to the TSO for the past five years. Large industrial consumers of energy can provide such services by being more flexible with their power demand in response to market signals, while BESS technology enables them to also provide power to the grid.

Arctic Paper is a producer of paper, packaging and pulp products. S.E.R Sverige appears to be a developer with a focus on distributed-size BESS projects, although the projects with Arctic would be much larger than anything it has done to-date.

S.E.R.’s website shows that it offers community ownership of BESS, allowing anyone to invest in and receive returns from projects. Its main technology provider to-date has been Pixii, the Finland-headquartered BESS integrator with a focus on the commercial & industrial (C&I) market.

Large-scale BESS in Sweden are being built at scale as developers capitalise on significant opportunities in the country’s system service, often called ancillary services, market. Those are set to provide the majority of the revenue stack for several years, companies active in playing them into the market have told Energy-Storage.news.

Arctic Paper has another mill in Poland, called Kostrzyn, and is also headquartered in the country. CEO Michał Jarczyński said it will use the experience from the Swedish market to provide the same system services in Poland. Poland is set to be one of the most active energy storage markets in all of Central and Eastern Europe.

Jarczyński, said: “In line with our strategy to invest in energy, we are happy to enter a cooperation with S.E.R Sverige. Being large energy consumers with high-capacity connections, our mills have a significant advantage in terms of managing the power grid. An additional value is the gathering of experience from the Swedish market, so that Arctic Paper also can provide grid system services in Poland.”
