Alfen collaborates with Ellevio to deliver Sweden’s largest grid-scale battery
The Swedish energy company Ellevio is expanding its space to help industries and companies become fossil-free through electrification. Its first project – Sweden’s largest grid battery – includes Alfen’s 10 MW modular energy storage system, TheBattery ElementsTMwhich enables optimal use of renewable energy and stability in the electricity grid.
“Increasing renewable energy sources, decentralizing energy and growing electricity consumption are creating challenges for the European grid,” says Stephanie Schockaert, sales director for Alfen’s energy storage division. “Solutions such as battery energy storage systems that are seamlessly integrated into the medium voltage grid solve these problems for grid operators. With our Finnish subsidiary Alfen Elkamo, we are proud to help build the power grid of the future with our fully integrated solutions. In this way, we support Ellevio when they work to reach their goals, and we contribute to them in our home country of Sweden.”
Sweden is one of the first countries in the world to adopt a net zero emissions target, which it intends to achieve by 2045. At the same time, Sweden expects to more than double its electricity consumption over the next 25 years using its main source of new electricity generation from wind power. Depending on how much wind there is, the amount of electricity fed into the grid will vary. If the balance is upset, there is a risk of disruptions in the electricity system which can be both costly and lead to dangerous grid outages.
Alfen’s TheBattery Elements can help balance these disturbances. It is an industrial and modular energy storage system equipped with fast frequency reserve (FFR) control technology that can handle the fluctuations (low inertia situations) in the Nordic grid using synthetic inertia. It requires very fast response times (<0.7 sec.) which is also supported by Alfen's proprietary software platform. The battery system can also be used for other network services and/or energy trading.
“For the energy transition to succeed, we must ensure that the flow of electricity in the electricity grid is stable,” says Kristofer Frøjd, Senior Vice President, strategy and business development at Ellevio AB. – We achieve that stability by building Sweden’s largest electricity grid battery that will support the state-owned Swedish Power Grid’s need to create balance in the national electricity grid. This is an important and exciting step in our journey to create energy solutions that help transform our energy system in Sweden.”
