Kalmar Energi creates smart district heating network using NODA’s technology for energy storage in buildings

Kalmar Energi and NODA Intelligent Systems are working together on an eco-smart and cost-effective district-heating network in Kalmar. The system is known as a Smart Heat Grid and is based on intelligent control functions that manage the district-heating network and coordinate the interaction between production, distribution and consumption in order to achieve energy efficiency and long-term sustainability.

One property has stored energy in the form of heat. When a number of properties are linked up, real-time analyses of the properties can be performed to optimally utilise this energy reserve. Through intelligent property controls the energy reserve can be put to better use in other parts of the network, thus reducing so-called peak load without affecting the indoor climate. This evens out the load on the grid over a 24-hour period, so the boilers do not need to work as hard and the flow through the district-heating pipes is more uniform, which is both cost-effective and extremely eco-smart. The concept is known as a Smart Heat Grid.

This system also enables new buildings to have district heating without needing to invest in more boilers or upgrade to larger district-heating pipes. The system also saves money and the environment. In short, a smart district-heating network yields more sustainable district heating.

“At Kvarnholmen in Kalmar there are plans for a new university, a hotel and other premises. Without a smart district-heating network Kalmar Energi would need to lay more district-heating pipes to Kvarnholmen. Now we can handle the new buildings with the existing district-heating pipework.”

Some fifty properties in Kalmar are equipped with NODA’s Smart Heat Grid solution, thus establishing a large energy reserve. Back in 2014/2015, 10 buildings in Kalmar were linked up in a Smart Heat Grid, with very positive results. So, Kalmar Energi is now moving forward and linking together a further 40 premises, including the new Linnaeus University.
