Smart Heating and Cooling in the EU
November 2016

This is the year of delivery:
Director General highlights CELSIUS

The Euroheat & Power District Energy Days in Brussels is a high level forum for policy makers, industry and civil society. The topic: how thermal networks can advance a smoother energy transition in Europe. CELSIUS was pointed out as a leading player in the keynote speech.

The subject of the conference is urgent; the Commission Vice President has described 2016 as the year of delivery for the Energy Union. Meeting its objectives will require a major contribution from district energy.
Keynote speaker was Dominique Ristori, the EU Commission Director General for Energy, who stressed the need to make serious progress in the coming years in replacing current heating systems with new, efficient solutions. In his speech, CELSIUS was highlighted as a leading player in this development.
“Modern district energy has the key characteristics to make heating and cooling efficient, sustainable and smart, especially in highly dense cities. Many of our cities have taken a leading role in this movement, such as the CELSIUS cities. They are developing and building the next generation of district energy systems, as part of a sustainable energy plan.
We will continue the journey to fulfil the potential of district energy. Utilizing the momentum we have built the last couple of years, 2016 will be the year of delivery for the Energy Union.”

CELSIUS opens up to more than cities

CELSIUS is now broadening the network and welcoming other district energy players to join by becoming CELSIUS City Supporters. Many have expressed interest and so far, nine of them have already joined.

The supporters can be private companies, civil society actors, professional associations, research institutions, or other EU projects who share CELSIUS’ commitment to sustainable energy use.
”We want to expand the network, this is a very important part of our work right now. In order to make the expansion of district heating and cooling happen, we need more players supporting the cities. Here their interests can be connected and the parties brought closer to each other”, says Helena Nordström, CELSIUS head of communication and market outreach.
The supporters sign a letter of intent where they specify their contribution to supporting CELSIUS Member Cities: via the CELSIUS Toolbox, in workshops or webinars. 

Oslo: abandoning oil for green energy

The capital of an oil-producing nation is now working intensely to replace oil-based heating systems with green district heating. In order to avoid unnecessary mistakes on the way, Oslo joined CELSIUS.

Even though the Norwegian capital has provided its citizens with district heating since the 1950s, the city of Oslo still feels the need for exchanging knowledge and experiences with other cities. That was the reason for joining CELSIUS.
The DH system has been extensively expanded during the last 30 years. In 2015 the Oslo energy utility Hafslund produced 1,6 TWh heat which corresponds to about 20 per cent of the city’s heat demand. About 880 apartment buildings, 3300 houses and 1100 commercial buildings are connected to the district heating network.
Even bigger plans are underway.
- The Oslo municipality and Hafslund Heat are now cooperating to convert the remaining oil based heating systems to green district heating, says Anders Westin, business developer at Hafslund.
What is your vision for district energy in the future?
- Our goal is to produce 2 TWh heat in 2020. The city of Oslo also wishes to facilitate a widespread deployment of low temperature grids in interaction with the existing high temperature grids.
District cooling though, poses a challenge. Hafslund have been losing customers lately because they do not provide district cooling.

Making the necessary investments to install district cooling in the centre of Oslo will be very expensive and the temperature of the water varies too much in the summer, the closest stable sea temperatures are 4 kilometres away. But Hafslund still aims to become the preferred producer and distributor of cooling.
In your opinion, what makes district energy a good solution?
- It has the advantage of being able to use energy that would otherwise be lost. It also offers flexibility to energy systems. A large district system for heating and cooling ensures the availability of energy in large quantities, thereby enhancing the security of delivery, says Anders Westin.

New: CELSIUS City talks

Speaking about Olso: it is one of the first cities to be featured in a CELSIUS City Talk. This new type of webinar focuses on present challenges faced by particular cities.

“This is a new approach that we have developed. In order to address the city’s needs we invite experts to an open discussion, approaching a solution together. It becomes more concrete than when just posing a general question", says Helena Nordström, CELSIUS head of communication and market outreach.
The first CELSIUS City Talk was held together with Ljubljana in September on end-user acceptance and substation optimization. Oslo was next, discussing solutions for their cooling dilemma, see article above. Next in line is Lille on November 23.
“We think highlighting the situation of one city makes our webinars even more pertinent. At the same time, we obviously believe that other cities with similar challenges can make use of the information”, says Helena Nordström.

Upcoming webinars

16 November:
CELSIUS Talk: IT Solutions for Demand Side Management

23 November: 
CELSIUS City Talk: Lille

Webinars are by invitation only and priority will be given to CELSIUS member cities.
Get the talk going on LinkedIn

CELSIUS now has a LinkedIn group where cities and supporters can discuss topics concerning the expansion of district heating systems, get advice or form new partnerships.

On LinkedIn, representatives from CELSIUS Member Cities and CELSIUS City Supporters can pose questions or start discussions and anyone with relevant expertise or experience can reply.

Ask for access to the group here.


To increase energy efficiency in the EU, CELSIUS helps cities across Europe to develop secure, affordable and low carbon district heating and cooling solutions that form part of the city's wider energy system. The focus is on maximising the use of waste heat or secondary heat within a city by capturing and using it in the heating system.

This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no 314441.
