Karlshamn Energi

Karlshamn Energi has connected about 90 buildings to Demand Side Management (DSM) through NODA Heat Network in their district heating system. The buildings are used as a virtual storage that Karlshamn Energi can activate from their control room. This extra flexibility is used to reduce peak loads during cold winter days, or to reduce the general energy usage during maintenance down-time in the nearby industry supplying excess heat as base load. The connected buildings represent about 15-20 % of the total annual heat demand of nearly 200 GWh.

Since the winter of 2019-2020, Dynamic Supply Temperature (DST) is also being evaluated in Karlshamn. DST is used for optimising the supply temperature from production and uses self-learning algorithms to continuously analyse the actual heat demand in the district heating system so that supply and demand is always matched evenly. This helps to reduce system temperatures which leads to financial as well as environmental benefits.

Karlshamn Energi and NODA have worked together for many years and has participated in several joint innovation projects where Karlshamn Energi has been an early test customer for new solutions.

Karlshamn Energi delivers electricity, district heating, broadband and water, and is owned by the municipality of Karlshamn.
