Valmet to supply automation to Lahti Energia's Kymijärvi III bio heat plant

Finland-headed forest industry and energy technology major Valmet Oyj has announced that it has received an automation order from Lahti Energia Oy for the Kymijärvi III bio heating plant currently under construction in Lahti, Finland. The value of the order is approximately EUR 2 million and the system commissioning is scheduled for 2020.

The scope of delivery consists of a Valmet DNA automation system, safety-related systems, an information management system, including applications for fuel data management, emission calculations and power plant key performance indicator (KPI) calculations, and a district heating optimization solution.

According to Valmet, a unique feature of the system is that it is based on a virtualized server structure, which reduces the number of physical servers and stations, thus simplifying maintenance and improving the system’s scalability for future needs.

Lahti Energia is happy that Valmet’s offer was the most competitive in the public procurement. We are confident that Valmet is able to deliver a system that will fulfil our needs long into the future, said Mika Timonen, Project Manager, Lahti Energia.

Cooperation between Lahti Energia and Valmet started in the 1990s with an automation modernization at the Kymijärvi I plant. In 2012, Lahti Energia started up its Kymijärvi II power plant, which features the world’s first solid recovered fuel (SRF) gasification process and is run with Valmet’s automation technology.

Additionally, the company uses the Valmet DNA system to manage operations at its heating plants in Lahti as well as in the neighbouring communities of Heinola and Vääksy.

Valmet is very delighted to be able to continue and further develop the solid, long-lasting cooperation with Lahti Energy with this Kymijärvi III bio heating plant project, too, said Olli Koivumäki, Sales Director, Automation, Valmet.

The new Kymijärvi III bio heating plant will replace the coal-fired Kymijärvi I plant that was started up in the 1970s. The new heating plant will decrease Lahti Energia’s carbon dioxide (CO2) emissions by 600 000 tonnes per year. The district heat capacity of the plant will be approximately 190 MW.
