Ingrid, in partnership with the SEB Nordic Energy Fund through Locus Energy, is strengthening grid flexibility in western Sweden - contributing to a doubling of Effekthandel Väst

A battery energy storage facility in Sweden developed and optimised by Ingrid

Ingrid, and the SEB Nordic Energy Fund through Locus Energy, have through their collaboration with Göteborg Energi, played an important role in enabling the local flexibility market Effekthandel Väst to double its capacity this year to 70 MW - equivalent to the electricity consumption of a mid-sized Swedish city. This is one of several initiatives through which the companies are helping to make the electricity grid more intelligent, increase the utilisation of existing infrastructure, and create better conditions for local growth and more stable electricity prices.

Battery storage that relieves the grid in real time

By participating in local flexibility markets, Ingrid provides flexible resources to the electricity grid. In practice, flexibility trading means that flexible actors temporarily reduce their electricity consumption, increase their electricity production, or use energy storage to ease the load on the grid.

Effekthandel Väst is a local flexibility market in which Göteborg Energi Nät acts as the buyer, securing capacity for the region. Ingrid participates with its 24 MW battery in Gothenburg, which the company owns together with Locus Energy. The facility is controlled via Ingrid’s proprietary trading and optimisation platform and can deliver power in real time when the grid is under stress. The result is a more robust power system that enables more connections and reduces the risk of capacity shortages.

This year, the available flexibility in Effekthandel Väst has doubled to 70 MW, thanks in part to the collaboration between Ingrid and Effekthandel Väst that began in late summer 2025.

Comments from the parties

“Local flexibility markets such as Effekthandel Väst are an important part of our work to create an intelligent and future-proof power system. Through our close and valued collaboration with Göteborg Energi, we can strengthen grid resilience, increase security for customers, and improve conditions for businesses. This is a clear example of the kind of innovation and cooperation needed to transform the energy system,” says Nicklas Bäcker, co-founder and Chief Strategy Officer at Ingrid.

“Thanks to the collaboration with companies such as Ingrid and Locus Energy, who actively help relieve the grid during critical hours, we can connect more new customers to the network without having to wait for grid reinforcements at the national or regional level. In addition, there is a shared learning process and interaction with these types of actors, who already participate in other markets,” says Therese Ceasar, Head of Flexibility at Göteborgs Energi Nät.

“Our goal is to strengthen local value creation and contribute to a more flexible power system. With our portfolio of hydropower, batteries, and wind power – with most connections located in local grids – Locus Energy can create tangible benefits for grid owners across the country. We are therefore very pleased, together with Ingrid, to support Göteborg Energi in balancing their loads and helping to build a more robust future grid with our batteries,” says Mattias Söderquist, Deputy CEO and Partner at Locus Energy.

Ingrid’s growing presence in western Sweden

Ingrid operates and optimises a battery storage facility in Gothenburg that is part of Effekthandel Väst. In the Västra Götaland region, the company also operates and optimises battery storage facilities in Falköping and Lerum, and is constructing additional sites in Tuve, Lidköping, and Götene. These facilities are expected to be commissioned in 2026. All six battery storage sites are jointly owned with Locus Energy.

Ingrid builds the infrastructure and software that make the European power grid more intelligent

In total, Ingrid has more than 20 battery storage facilities in operation or under construction in Sweden’s SE3 and SE4 price areas. The company is currently building Finland’s largest battery storage system - 70 MW / 140 MWh in Nivala - a project jointly owned with Locus Energy. Ingrid recently announced a partnership with Energiequelle GmbH to develop a 200 MW portfolio of battery storage projects in Germany.

In addition to energy storage, Ingrid develops advanced optimization solutions for battery systems and renewable energy assets, creates structures for green energy supply and power offtake agreements, and provides innovative solutions for grid operators.
