Largest Project for Remote Polling of District Heating Data in Western Europe

At the beginning of December 2017, SAMSON AKTIENGESELLSCHAFT and Vattenfall Wärme Berlin AG signed a contract to interconnect more than 31,000 district heating stations in Berlin, Germany using the cloud-based SAM DISTRICT ENERGY application. By the end of 2018, 24,400 utility meters and 3,000 district heating controllers will be linked to SAM DISTRICT ENERGY using 19,100 GPRS gateways. Another 12,600 GPRS gateways are to be installed and connected in Hamburg by the end of 2021. Starting in mid-2018, SAMSON will make the SAM DISTRICT ENERGY services available to its customer Vattenfall all around the clock. The contract value is in the high single-digit million euro range.

Gateways are used to record the energy consumption at every station and make the associated data available on the central SAM DISTRICT ENERGY platform. For this purpose, the smart gateways are connected to the utility meters as well as to SAM DISTRICT ENERGY. They poll the consumption data from the meters and transmit them to the platform. Meter numbers and consumption data are clearly assigned to one another in SAM DISTRICT ENERGY so that the heat consumption and billing information are updated every 15 minutes for every customer. It is no longer necessary to read the meters on site. The large amount of data recorded also makes it possible to analyze the local and district heating networks the consumers are connected to and increase their efficiency. The resulting benefits are a lower energy consumption and reduced carbon dioxide emissions.
