Rejlers supports Lahti Energia in constructing a district heat accumulator to enhance energy system flexibility

Lahti Energia is set to enhance its energy efficiency with the construction of a new district heat accumulator at the Kymijärvi power plant. Rejlers has been selected as the engineering partner for the project, providing detailed design services to ensure successful implementation.  

The project will kick off with planning this autumn, with construction scheduled for 2025. The new district heat accumulator is expected to be operational by 2026, offering improved flexibility in heat production and consumption.

"The district heat accumulator provides us with flexibility and efficiency. We can fully utilise the Kymijärvi electric boiler under construction and respond quickly to the highly volatile electricity market if necessary. Additionally, the district heat accumulator will improve our ability to integrate waste and surplus heat into our district heating network”, says Sandor Luukkanen, Director, Energy Production and Projects at Lahti Energia.

Rejlers has a proven track record in supporting green transition projects and is proud to continue its partnership with Lahti Energia.

"We are delighted to be part of this important initiative, contributing to energy efficiency and the use of renewable resources”, says Jussi Likitalo, responsible for Rejlers’ industrial project deliveries.
