Valmet Oyj will supply a complete district heating plant to Göteborg Energi AB in Gothenburg, Sweden.

The new hot water plant, which is typically worth above €40 million, will reduce fossil carbon dioxide (CO2) emissions by around 25,000 tons per year. It will replace two old boilers originally designed for oil and coal but converted to run on wood pellets in 2003. Demolition of the existing plant will begin in April 2021 and the new plant will be operational in December 2021.

Valmet’s boiler will be 25% larger than the old two boilers combined, with a fuel capacity of 130 MW, and have a longer operating season. As the number of operating hours on pellets will increase, the use of natural gas will decrease; the ash from the combustion will also be returned to the forest.

Anna Svernlov, head of production at Göteborg Energi, said: “The goal of Goteborg Energi is that our production of district heat will emit zero CO2 by 2025. We have already taken many steps toward that goal, and I am very happy we are now also upgrading our Rya district heating plant.

“We will get a plant with modern technology that will serve us well for many years to come. Going forward, we will continue with our other planned step toward a more sustainable city.”

“This is an important continuation of Valmet’s deliveries of pellet-fired plants and the scope of the project is unique,” commented Mikael Barkar, senior sales manager of energy sales and services operations, EMEA, Valmet. “The flue gas cleaning system will represent the best currently available technology, and the plant will be equipped with Valmet Industrial Internet solutions, too.

“This advanced technology will provide information on where maintenance is needed, enabling higher reliability and performance. This is an exciting project for Valmet, and we are looking forward to completing it together with Göteborg Energi.”
