This report has been established within the Flexiheat project. Flexiheat has focused on increasing flexibility in district heating systems. The intelligent district heating network is a dynamic network: an open network where different waste heat and renewable energy sources are connected, that has multiple producers and groups of consumers and facilitates the connection between different energy infrastructures (gas, heat and electricity). Eventually this will lead to an optimal deployment of the available heat sources and an increased cost-efficiency of district heating. Flexiheat aims to develop new concepts for these intelligent, flexible district heating networks. One of the strategies is to allow third party access to the network. A smart control system is developed to manage the heat flows across the network. This system makes use of dynamic pricing. In this exploration the concept of third party access in relation to the Flexiheat project will be discussed. The development of new business and price models based on the Flexiheat approach has led to an analysis of possible alternative price models for consumers.

The sustainable energy transition asks for new and innovative solutions in the way society, government, energy market and clients (end users) approach energy distribution and consumption. The energy transition provides great opportunity to develop innovative solutions where in the dense built environment district heating and cooling are being strongly advocated.Traditionally, the energy systems in urban districts have been regulated by a top-down approach. With the rise of local and distributed sustainable sources for urban heating and cooling, the complexity of the heat/cold chain is increasing. Therefore, an organic and bottom-up approach is being requested, where the public authorities have a facilitating and/or directive role. There is a need for a new and open framework for collaboration between stakeholders. A framework that provides insight into the integral consideration of heating and cooling solutions on district level in terms of: organisation, technology and economy (OTE). This research therefore focuses on developing this integral framework towards widely supported heating and cooling solutions among district stakeholders.Through in-depth interviews, workshops and focus groups discussions, relevant stakeholders in local district heating/cooling of varying backgrounds and expertise have been consulted. This has led to two pillars in a framework. Firstly the definition of Key Success Factors and Key Performance Indicators to evaluate technical solutions in light of the respective context. Secondly, an iterative decision making process among district stakeholders where technical scenarios, respective financial business cases and market organisation are being negotiated. Fundamental proposition of the framework is the recurrent interaction between OTE factors throughout the entire decision making process. In order to constantly assure broad-based support, the underlying nature of possible barriers for collaboration are identified in a stakeholder matrix, informing a stakeholder strategy. It reveals an open insight of the interests, concerns, and barriers among all stakeholders, where solutions can be developed effectively.

Lessons learned on the progress towards 4th generation district heating (4DHC) are presented from 6 pilot implementation projects in the UK, Ireland, Belgium, France, and the Netherlands (HeatNet project). The pilots have implemented the infrastructure for district heating from various (waste) heat and renewable sources to reduce CO2 emissions. With the development of long term road maps, progress is made towards the role out of 4DHC in the regions. The pilots have a different level of experience with district heating and transnational learning is specifically addressed. Purpose of the evaluation of the pilots is to give local authorities insight into barriers and solutions and the way they are closely linked to stakeholders in their geographical, politicaland cultural context in NWE. To do this, the financial, regulatory and organisational barriers the pilots face and possible solutions that were shared between the pilots are analysed in the context of system innovation. Differences in national and regional contexts have been analysed to be able to generalise solutions to a level they can be used in a different context. We will confront the pilot’s development with best and worst practice from literature and score Key Success Factors.

The key societal problem addressed by the EmPowerED consortium is the urgent need to accelerate and scale up the development of Positive Energy Districts (PEDs). Carbon neutral heating and cooling is a core element of the design of Positive Energy Districts (PEDS). However, many Dutch heat transition projects run behind schedule and are not compatible with this future vision of PEDs, making the heat transition a key factor in PED realization and upscaling. In this heat transition and the transition to PEDs, citizen engagement and support is a key societal factor and citizens need to be an integral part of the decision-making process on the realization of PEDs. Furthermore, technical, regulatory and financial uncertainties hamper the ability of decision makers to create PED system designs that have citizen support. Such system designs require a deep understanding of the relevant social, spatial, governance, legal, financial, and technical factors, and their interactions in PED system designs.
