Lappeenrannan Lämpövoima

The district heating facility of Lappeenrannan Lämpövoima was the first pilot project of Elstor. The unit was originally delivered to Mustola for district heating production to replace the use of natural gas. Based on the pilot, the device has been developed to be more reliable, sustainable, and even safer. After the initial pilot, the upgraded device was transferred to the Selkäharju district heating network.

Initial Situation in Selkäharju

In Lappeenranta, the Selkäharju area operates a separate district heating network. Heat has been produced in this network, among other methods, by burning natural gas. The annual carbon dioxide emissions from the use of natural gas are approximately 320 tonnes.

“The thermal accumulator replaces natural gas, and it is estimated to reduce annual carbon dioxide emissions by over 300 tCO2e.” Miika Alatalo, Expert, City of Lappeenranta

Situation with Elstor Device

Elstor device produces heat for the local district heating network. Heat produced with carbon-free electricity replaces the use of natural gas, reducing carbon dioxide emissions of the heat production. Lappeenrannan Lämpövoima has expanded the Selkäharju district heating network due to the additional production introduced by Elstor device.

“Thanks to Elstor’s storage capacity, heat can be produced when there is excess electricity and released exactly when the district heating network requires it. This allows for smoothing the operation of the electricity grid. Elstor’s device enables the expansion of the Selkäharju district heating network with a new modern and cost-effective production facility.”
