Metering and billing of consumption in ultra-low temperature district heating systems

Metering and billing of consumption in ultra-low temperature district heating systems

In general, metering of district heating consumption in ultra-low temperature district heating (ULT DH) systems is not different from traditional district heating. However, when electricity is used to boost DHW temperature, this share of the DHW production is no longer metered by the district heating company,or must be metered separately by an additional electricity meter. This information has been extracted …

District heating: the key to decarbonising Europe’s heating

District heating: the key to decarbonising Europe’s heating

District heating (DH) systems are one of the most energy efficient heating systems in urban environments, with proven reliability within many decades already. District heating systems are identified as key systems to achieve the de-carbonization of heating energy in European Cities. Renewable and waste heat sources are foreseen at the same time as decarbonized heat sources and the way to …

Machine Learning as a solution tool for district heating

In recent years, Machine Learning has become one of the most used techniques when modelling relationships between different parameters. Inspired by the successful integration of Machine Learning in many other areas, it is beginning to draw attention in the district heating sector as well. The application of Machine Learning in the context of district heating has an obvious potential as …

Solar thermal potential in the district heating system of Belgrade City

The use of renewable energy sources as biomass, solar thermal solutions, geothermal energy, and waste heat is becoming more popular in Europe. The transition of district heating systems from fossil fuels to renewables is the next step in the development of district heating, but there is still a lot of work ahead for everyone, not only in the local level …

District Heating De-Carbonisation in Belgrade. Roadmap.

District Heating De-Carbonisation in Belgrade. Roadmap.

The operation temperatures of today’s district heating systems are too high for a massive integration of renewable systems, while the current control systems are no able to properly introduce weather-dependent, distributed heat sources such as solar systems. The district heating strategy for the city of Belgrade (Serbia) addresses these barriers with the focus to de-carbonising the city on a multi-year …

Demonstration site: the conversion of the district heating network of Iurreta into an ultra-low temperature system

Demonstration site: the conversion of the district heating network of Iurreta into an ultra-low temperature system

The main aim of Iurreta demonstration site is to tests the possibilities of the ultra-low temperature district heating systems in corporate building complexes. For such purpose, the intervention proposed within the framework of RELaTED project requires the conversion of current district heating network into an ultra-low temperature system, where the operation temperatures are reduced, and additional distributed renewable heat sources …

About RELaTED project

The project “Renewable Low Temperature District” (RELaTED), funded under the European Union’s Horizon 2020 research and innovation programme, aims to develop a robust ultra-low temperature concept, which allow for the incorporation of low-grade heat sources with minimal constraints.

The main objective is to demonstrate the feasibility of the concept in European urban environments, and its suitability for the upcoming operational environment with reduced heat loads and distributed heat sources. To prove this, the concept will be demonstrated in four real demonstrations sites (Denmark, Estonia, Serbia and Spain), with two additional feasibility studies. However, some technologies must be adapted to the particularities of the system.

Under the coordination of TECNALIA Research & Innovation, the Consortium is composed by the companies NIBE, METRO THERM, AVENTA SOLAR, IMAR, IBS, TDC, Mazovian Energy Agency, Basque Energy Agency and FEDARENE; and DH operators as BEOELEKTRANE, FORTUM Tartu, DTI and the Basque Government. These companies will work together to provide a framework for the integration of many renewable heat sources into a low temperature DH system.
