SIG – Geneva District Heating – visit to DBDH

1. February 2018 - 2. February 2018

Geneva District Heating (SIG) will visit DBDH on 1-2 February, 2018

DBDH Members,

Yet another members only event! This time we have the pleasure to introduce you to a delegation from SIG – the Geneva District Heating Company. They will visit Copenhagen for 2 days to be introduced to the way we do DH in Denmark and not least to be inspired by new innovations and developments. SIG has a significant DH system today as well as long term plans – as can be seen from this presentation. I just picked a few numbers: 60.000 customers, 500 GWH supplied heat, 23 GWH cooling….. Below you find a short introduction to SIG including titles of the participants.

There are 2 ways to take part in this program – both are free of charge:

  • Participate in the afternoon workshop Thursday February 1st at DBDH with a presentation and the possibility to network and inspire
  • Suggest a site visit in Copenhagen you would like the delegation to experience – and demonstrate first-hand how we do things

Actually, there is a 3rd option – participate in the dinner Thursday evening – at a minimal fee. Take a look at this first draft – plenty of time to present your solution.

Now, what are SIG interested in?

  • How to ensure quality control of the network pipe in order to have a long lifespan for the owner ?
  • How the business model of District Heating & Cooling is established in Denmark and how the government ensure that all DH&C companies have a similar accounting model ?
  • How to control and decrease return temperature of DH ? Thanks to a lower return temperature, which new applications are possible ?
  • Which solutions are used for leakage detection ? How to ensure a performant leak detection system ?
  • How hydraulic balancing is realized on district heating networks ?
  • Heat storage : what are the rules, the good practices to take into account ?
  • What are the latest innovative solutions from manufacturer ?
  • How to take into account end-user satisfaction ?
  • How to use new technology like IoT (Internet of Things) ?

And, what would SIG like to see:

  • Prefabricated substations working
  • Network chamber
  • Leak detection system running
  • Construction site of new pipe (in progress) to see how the work is done
  • Network distribution : pumping
  • Expert system (decision support system)
  • Hydraulic balancing system ?

Take a look at the different aspects SIG are interested in – or suggest your own! And then sign up as soon as possible by writing to Morten Duedahl – deadline January 3rd.

Participants from SIG are:

  • Thermal & Hydraulic Competence Manager
  • Thermal & Hydraulic Unit Senior Manager
  • DH&C Operations Manager
  • Asset Manager
  • Project Management Engineer
  • Industrial Computing and Automation Unit Manager
  • Automation Manager
  • Project Engineer Senior Manager
  • Thermal Engineer & Project assistant
  • Head of DH&C division
  • Thermal & Hydraulic Engineer

Background information from SIG
SIG is an autonomous public utility company which provides drinking water, electricity, natural gas, FTTH, district heating and cooling all over the canton of Geneva. The company is also handling the incineration of household waste and the treatment of waste water.

The thermal division is in charge of the district and cooling network. This division is split in 2 parts: the operation unit which is in charge of operating the networks, maintenance and asset management; and the development unit that is in charge of developing new energy network, new thermal solution and new renewable sources.

Today, our district heating cover 10% of the heat demand of the canton of Geneva which represents an annual demand of more than 500 GWh of heat. Half of this energy comes from waste energy. Our goal is to reach 30% of the heat demand in 2035 with at least 60% from renewable and waste energies.
