PhD defence: Chapter 1 A of the Heat Supply Act and its Impact upon Municipal Engagemetn in Strategic Energy Planning

Thursday 28th September, 2017 Michael Herborn, from the Department of Law of University of Southern Denmark, successfully defended his PhD thesis entitled: “Chapter 1a of the Heat Supply Act and its Impact Upon Municipal Engagement in Strategic Energy Planning".

His thesis examines the impact of the codification of municipal engagement in the heat supply market upon the ability of municipalities to engage in strategic energy planning in pursuit of transitioning the Danish energy sector to one based entirely upon renewable energy by the year 2050. 

According to Michael Herborn, there is perhaps cause for re-evaluating of the basic principles, particularly given that the availability of other technologies for individual heat supply are on the increase. This would though constitute a significant alteration of the policy behind the Heat Supply Act and the laws that are set out in Chapter 4 of the Act in particular, though also planning powers under Chapters 2 and 3. By placing the development of heat planning laws in the context of the series of major statutory interventions that took place in the energy sector in the years following the energy crises of the 1970s, not least the 1979 Heat Supply Act, it can be seen that Denmark locked-in certain technological solutions for the energy sector. Doing so was a conscious planning decision based around the rollout of two particular technologies – district heating and natural gas. Similarly, the promotion of CHP plants, following the 1990 Heat Supply Act, was a conscious policy decision. The same cannot be said of the technological limitations placed upon municipal engagement in the heat sector following the introduction of Chapter 1a. Planning takes place in a continuum and the technologies locked in in the 1970s, 1980s and 1990s were locked in as part of a plan. Given the importance of the transition to a carbon-free energy sector, the time is now ripe to re-evaluate heat supply law in a manner that reflects the changed technologies.

Substation with electrical booster lowers DH temperature to 40°C

4DH partner Danfoss and the consortium of partners in this project developed and tested a concept of ultra-low-temperature district heating with the supply temperature as low as 40°C combined with instantaneous electric heater topping up the last few degrees of domestic hot water heating. The project was supported by Danish research program EUDP.

Large potential to heat existing buildings with 4GDH

4DH PhD Fellow Dorte Skaarup Østergaard investigates how to heat existing buildings with low-temperature district heating. Through detailed simulation calculations of the typical buildings, she calculates the realistic dynamic heating load and compares it to the heating power of the existing heating elements with a low supply temperature.

Smart metering provides the transparency required for high energy efficiency

4DH partner Kamstrup works according to the principle that you cannot optimise what you do not measure. With innovative and intelligent metering solutions they help utilities optimise their efficiency while meeting regulatory objectives and directives.

Through the 4DH project, Kamstrup has been able to further explore the key role that data plays in achieving higher energy efficiency. This has contributed to the identification and testing of specific application areas where frequent data from smart meters are crucial elements of energy optimisation in an integrated energy system.

Software simulates district heating networks

4DH PhD Fellow, Soma Mohammadi, has developed a tool in MATLAB for thermal-dynamic modeling of district heating networks.

The tool can be applied for modeling the operational performance of district heating networks, furthermore as an assessment tool to evaluate the feasibility of implementing alternative design concepts and strategies in the move towards low-temperature district heating.
