RELaTED project demo site: intervention plan in Belgrade’s district heating system

The RELaTED ultra-low temperature district heating concept and technologies will be tested in Belgrade, the capital of Serbia. The heating system of Belgrade is one of the largest in the region, with the installed power of 3GW in 40 heat sources, an annual production of heat energy of 3,66 GWh, a district heating network of 750 km long and 9,000 substations. Know more about the different interventions to be performed by RELaTED project in this city in the following document.  This browser does not support PDFs.

New posibilities for ultra-low temperature district heating in corporate district heating networks

Olga Macias, researcher in the field of energy eficiency in buildings in Tecnalia, explains the intervention developed by the RELaTED project in the demonstration site of Iurreta (Spain), in order to test the posibilites of the ultra-low temperature district heating systems  in a corporate building complex. Tecnalia coordinates the RELaTED project which aims to develop an innovative concept of desentralized ultra-low temperature district heating networks. This new concept will be tested in four demonstrations sites, in Denmark, Serbia, Estonia and Spain. The Spanish project is located in Iurreta, in the North of Spain. This site is a policial base owned by the Department of Security of the Basque Goverment. The based consists on a total of thirteen buildings with diferent [...]

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 from the section 5 of the document D.2.2. Interconnection schemes for consumer installations. DOWNLOAD THIS DOCUMENT HERE >> Figure 3: principle of metering in ULT DH systems with electric booster In this case, there might be different ways to bill the consumer. One option is that the consumer is just billed the district heating consumption with usual tariffs, [...]

Main strategic and economic issues of ULT district heating for new development areas

The following article is resuming the main strategic and economic issues to be considered in developing new ultra-low temperature district heating (ULT DH) for new development areas.  This information has been extracted from the document entitled D2.5 - Development schemes for new district heating developments. Strategic and integrated energy planning The economy of ULT DH in a new development area must be economical attractive for the company operating the scheme, for the customers and for the society. Strategic energy planning is used on municipality, regional or national level to plan the most viable way to supply and use energy over a longer time horizon. Vision A new development area is typically based on or linked to one or more visions. [...]

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 guarantee competitive energy costs with limited influence of fossil fuel supply price volatility. To achieve this, a transition is needed in DHs, comprising not only measures to improve overall performance (temperature level reductions, improvement of substations, etc.), but to guarantee system viability as a whole in a context of reduced heat loads with the transition to Near Zero Energy Buildings [...]

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 a component of tomorrows heating networks. Machine learning (ML) is a fast-developing tool that allows you to handle large and complex systems with many parameters and data, with different desires for efficiency. It is a branch of artificial intelligence, and defined by Computer Scientist and machine learning pioneer Tom M. Mitchell in relation to his book Machine Learning (1997) [2] [...]

The RELaTED project will help us to improve Belgrade DH system in terms of decarbonization

Author: Ljubisa Vladic, Deputy of Production and Distribution Manager at PUC Beogradske Elektrane. Ljubisa Vladic, Deputy of Production and Distribution Manager at PUC Beogradske Elektrane. Belgrade DH system have significantly upgraded in the past decade in terms of increasing energy efficiency and reliable delivery of thermal energy. The RELaTED project, in which we participate as partners, will further help us to further improve the system in terms of lowering the temperature of the district heating network and decarbonization. It will be particularly important for us to look at the possibilities of local application of solar energy. It will be particularly important for us to look at the possibilities of local application of solar energy, which will be implemented [...]

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 but in the whole world. Chairs of Opening ceremony: prof. dr Branislav Todorović, prof. dr Bratislav Blagojević and dr Milovan Živković (Photo: Serbian Society for HVAC&R). These are some of the topics discussed at the regional conference Renewable Energy Sources in District Heating and Cooling Systems held in Belgrade last december. This event was organized by the European [...]

Watch the Integration of Industrial Waste Heat in District Heating Systems [webinar]

Do not miss the recording of the second RELaTED webinar on the Integration of Industrial Waste Heat in District Heating and learn about the role of waste heat in DHs and the RELaTED project DH concept!   What’s new in District Heating Systems (DHs)? DHs have traditionally been designed to be operated with central energy production facilities and a variety of distributed consumption locations (dwellings, tertiary buildings, etc). In some cases, heat is partially obtained from local industrial waste heat streams, leading to almost de-carbonized heating energy supplies. In case you did not know about the role of waste heat in DHs, after watching this webinar you may have upskilled your knowledge about its benefits. Furthermore, the webinar allowed the [...]
