Optimizing Belgrade DH network

How the low temperature concepts can be applied for operational high temperature district heating networks? This report uses an example from Belgrade to illustrate and detail the guidelines of the RELaTED Development Schemes for new DH developments in new urban environments. Belgrade District heating network area The guidelines of RELaTED Task 2.6 are in general terms, based on best practice as most DH networks are different in relation to visions, DH network topology, temperature levels, building installations, tariff structure, management etc. This article focuses on the practical implementation of the transition schemes in the DH network in Belgrade. About Belgrade Belgrade is the capital of Serbia with about 2.000.000 inhabitants. It has a moderate continental climate. For the [...]

Regional feasibility studies of new DH in consolidated urban environments, technical financial and administrative roadmaps

The methodology developed within RELaTED identifies interesting interactions between heat sources and high dense areas, but fails to encounter fully successful outcomes. Read more here (PDF) >> The main output of this study is the definition of a procedure for the identification of opportunities of waste heat reuse with a practical application based on real data in both Basque country region and Mazovia region. This document included: Geoprocessing of information on Basque country. Phase 1 of the regional study, with an energy and administrative planning of DH in consolidated urban environments. The main output from this task is the methodology to define roadmaps for the planning of new DH networks in existing urban areas. This methodology has been [...]

Transition schemes for DH in operation

 The Guidelines of the task 2.6 will focus on energy planning and economy, Network topology, Scenarios for timeline and energy sources, necessary measures for implementation, project developments and operation and management. DOWNLOAD THE DOCUMENT HERE (PDF) >> One smaller generation plant with main network and subnetwork in Belgrade district heating network. In RELaTED Task 2.6 a set of guidelines were developed for how the low temperature concepts can be applied for operational high temperature district heating networks. This report (D2.6) is one of various RELaTED reports describing low temperature concepts from different perspectives. The report refers to other RELaTED reports when relevant. The guidelines of this report are in general terms, based on best practice as most DH [...]

The RELaTED Project consortium meets for its last General Assembly

After two days of meetings and hard work, RELaTED ends its last General Assembly. Due to the current sanitary situation, the meeting has, once more, taken place online. However, this has not prevented the partners from doing a thorough revision of all the developments and results obtained during the last months. Even though most work packages have already been finalized or are close do so, the agenda for the coming months will be intense. Specifically, several events are planned, among which we highlight those that will take place at the demonstration sites at Iurreta and Belgrade. Likewise, the consortium is working on the organization of the final seminar which will happen in Brussels in June 2022. We will inform about [...]

Interconnection schemes for producer installations

This report elucidates specific barriers and solutions for the use of distributed energy sources (DER) in ULT DH networks. Moreover, it will sketch solutions for producer connections to the network. The objective of this document is to investigate possible interconnection schemes for producer installations and to explore the control opportunities and strategies including local storage when relevant and with respect to the overall boundary conditions, pricing and taxes as well as regulation. DOWNLOAD DOCUMENT>> Example of BILST facade system. Source: IMAR singular metal solution. In RELaTED Task 2.3 the use of distributed energy sources and the possibilities for integration and control in district heating systems are presented along with legal and practical barriers and solutions as well as [...]

The business case for ULTDH using the RELaTED concept – Residential & commercial customers, and heat producers

The use of ULTDH network in combination with CHP, reversible heat pumps for heating & cooling, solar systems, and waste heat increases the energy performance in every case. Photo by jiawei cui from Pexels The RELaTED project assessed the business case for ULTDH using a decentralized approach to heat production, i.e. heat can be collected from multiple points within the district heating (DH) network, not just one location. This assessment was applied to the DH customer case for residential and non-residential buildings, and heat producers (DH company). For DH customers, the use of building integrated solar panels, heat pumps, and triple function substations were applied to the DH networks of Belgrade, Serbia, and Tartu, Estonia. For Heat producers, [...]

District heating cost modelling

The district heating (DH) cost modelling assessment addresses the long-term energy planning of DHs, considering the evolution of systems towards greater efficiency, lower distribution temperatures, greater shares of renewable energy and the incorporation of distributed renewables in the context of an increase of nearly zero energy efficient buildings (NZEBs). Foto de Magda Ehlers en Pexels. The cost modelling is one of the topics included in the report D4.6 (download report D4.6 here >>). The RELaTED project has addressed this issue in WP4 – Economic feasibility & business analysis. The report, D4.6, serves as a summary of the main findings for this WP as it relates to the profitable operation of the RELaTED DH networks. Heat production costs The [...]

Abstract Tartu DH network (Estonia), with the demo area highlighted in blue. District heating networks are considered to be a key element for the decarbonization of Europe. The RELaTED project seeks to contribute to the decarbonization of these infrastructures with the demonstration of low temperature district heating networks. One of the demonstration sites consists of more than 50 substations within a subsection of a larger network in the city of Tartu (Estonia), where the [...]

“RELaTED project has proven that de-carbonised and efficient district heating can be achieved”

Roberto Garay, RELaTED Project Coordinator RELaTED has been active since 2017. At that time, we envisioned a future where de-carbonised and efficient district heating could be achieved. We have actually done so. By the end of 2021, we have proven the feasibility of our concept. Furthermore, we have applied it in several networks representative of the diverse District Heating context in Europe. With progressive distribution temperature reductions, our experience in the Tarkon area is now extended over the full DH network in Tartu. Together with our local partner GREN, RELaTED has already tested the capacity to reduce distribution network loss by ca 5%. Belgrade has seen the renovation of the DH network in Vinogradski Venac. With this modernization, [...]
