HOT|COOL NO. 2/2019 - "Smart Heating System Integration"

P12

CONSTRUCTION WORK STARTED A public tender has been produced for four separate components: the district heating and cooling network, the building construction, the steel tank and the heat pump installation. The offers have been within the estimated budget, and the construction work started on 16th of May 2019. CONCLUSION This project demonstrates the benefits of local democratic ownership of all assets for energy and environment in the local community. This ownership serving the interest of all inhabitants and companies in the municipality opens for co-operation –

• The system has been prepared for additional capacity in a flexible and cost-effective way, by increasing peak from the storage tank, by investing in ground source cooling and by preparing the system for a mobile temporary chiller. • To avoid digging in an important road, a 160 m trench in DN300 for the cooling pipe and DN200 for the heating pipes was constructed with the nodig trench method as an alternative to a longer route. (See picture above.) • How to connect to the power grid: TF could buy low voltage power from a transformer, but TF decided to be owner of the new transformer and buy electricity directly from the high voltage grid.

the so-called “collective impact” – and transparent exchange of information and data among all stakeholders. Thereby it has been possible to identify the important economy of scale factors, synergies and local resources to optimize this smart integration to the benefit of the consumers. Since TF really started this journey in 1985, we have used digital simulation models and data, which have been necessary for optimal planning and operation, but this has just been tools. The important thing is the open cross-sector co- operation, which has enabled Taarnby Municipality to implement smart solutions, as if the local community was one large campus. We hope this project will inspire ministries, cities, utilities and large energy consumers in Denmark and internationally.
