“Energy storage is a logical step in the development of our renewable energy. We have built two solar parks in Latvia, and by introducing a battery system, we can now ensure better utilization of the green energy produced. Our goal is to create a future-proof energy solution that provides customers with stable and more affordable electricity even when the sun isn’t shining,” commented Margus Kaasik, Chairman of the Management Board of Elenger Grupp.
The battery system at the Nīca solar park can store 8 MWh of green energy and deliver 4 MW of power to the grid. This is enough to cover the daily electricity consumption of approximately 1,500 households or power an electric car for 50,000 kilometers.
The new system makes electricity consumption more flexible and improves grid reliability. It allows electricity to be stored when production is high or prices are low and used when demand and prices are higher. The storage system helps keep prices more stable, increases the share of renewable energy in the grid, and ensures supply security during outages or overloads. It can also be used to restart the grid in emergency situations.
Elenger opened the Nīca solar park in 2024 and continues to develop renewable energy in Latvia. In April 2025, a new solar power plant in Olaine began operations with an investment of €2.4 million. The plant produces 5.3 GWh of electricity annually, covering the consumption of about 2,500 households.
Elenger is the largest privately-owned energy company in the Baltic-Finnish region, operating in six markets — Finland, Estonia, Latvia, Lithuania, Poland, and Germany — and serving more than 450,000 customers. Elenger’s activities cover the entire energy value chain, including sales and trading, infrastructure, and production.
Elenger supplies Western-sourced natural gas and renewable biomethane and manages gas distribution networks in Estonia, Latvia, and Poland with a total length of 9,000 km. The company also sells electricity, including green power produced in its own solar parks, and is actively engaged in international energy trading. The group employs more than 1,000 people. Last year, the company’s turnover exceeded €1 billion. Elenger is wholly owned by Infortar, an investment company listed on the Nasdaq Tallinn Baltic Main List.
