Diehl Metering provides smart metering solutions to utilities companies through the intelligent networking of various metering devices into larger data platforms. Thanks to more than 20 years of experience with the company’s own radio technology, Diehl Metering has at its disposal excellent expertise in communications within the Internet of Things.
In 2020, Brønderslev Forsyning A/S further strengthened its solution by offering consumers the possibility to download IZAR@HOME for free. Through this smartphone app, the utility shares insights with consumers about their consumption patterns, empowering them to change their habits and save money. As well as offering added value to consumers, IZAR@HOME simultaneously provides a tool for Brønderslev Forsyning to increase the efficiency of its district heating network.
By customizing the app, the utility defines its own “utility target” that is consistent with its strategy of reducing return temperatures in the network to 30 °C or less. This target is visible to consumers in the app and, through simple graphics, they can track their current average return temperature over the past 12 months, and see if they are hitting the target.
Brønderslev Forsyning A/S benefits from new efficiencies in its network operations
Consumers can improve their return temperature, saving energy and money
Motivate consumers to reduce their return temperature with a pioneering pricing model
As a further incentive, Brønderslev Forsyning A/S introduced a new “motivation tariff” for its customers in 2021. The idea of this tariff is to encourage end users to adopt behavior that positively impacts the operation and overall economy of the heating plant, as well as reducing the volume of water pumped through the district heating system.
With the motivation tariff, consumers who do not sufficiently use the energy of the district heating water and are consequently responsible for high return temperatures in the system, have to pay a surcharge on their kWh consumption of 1 % for each degree they surpass the targeted average return temperature of 30 °C. As the utility is legally not allowed to make a profit on its new tariff and does not intend to do so, it has reduced the base heat price for all consumers, meaning that everyone can benefit.
Through IZAR@HOME, Brønderslev Forsyning A/S offers consumers full transparency on their consumption habits and clearly illustrates if their average return temperature is below the 30 °C threshold or not.
This creates a win-win situation whereby consumers are motivated to change their consumption behavior or optimize their own heating system and thus reduce their heating costs, which in turn drives greater efficiency of the district heating network. By introducing the motivation tariff and the IZAR@HOME app, Brønderslev Forsyning A/S can further reduce the return temperature in its district heating network, bringing significant benefits, including reduced heat loss in the distribution network, lower costs for pumping district heating water, higher efficiency of technical systems, lower consumption of wood chips by the power plant, and reduced overall CO2 emissions for greater sustainability.
Ultimately, this innovative use of IZAR@HOME results in a more efficient district heating network while reducing heating bills and further increasing customer satisfaction.
