High political responsibility
Government
• Energy policy• CHP strategy• Legislation• Taxation• Subsidies
Municipalities
• Heat planning• Implementation
of projects• Compulsory

Legal framework for DH in Denmark
• Monopoly business – no competition
• Non profit business• Well-defined delimitation to
natural gas• Municipal possibility for forced
connection of users to DH• Prices from CHP shall be
reasonable

Heat Plan Greater CopenhagenPurpose of Project
• To secure a reasonable development in heat priceand energy efficiency on the long run and at the same time maintain security of supply.
• To put focus on the role of DH when talking about CO2 reduction and renewable energy in the local society.
• To evaluate consequence on economic and macro economic issues on short and long run
• To generate interest for the development of the DH system in the Greater Copenhagen Area.
• To propagate the role of the DH companies.
• Is it realistic to reach 70 % RE in the DH system before 2025
![Page 18: Copenhagen Energy Summit Energy Tour - lsta.lt tours/1_District... · Copenhagen Energy Summit Energy Tour District Heating in Denmark Mr Jan Elleriis, Vice President, Metropolitan](https://reader034.vdocument.in/reader034/viewer/2022050119/5f50012b834ab936fe0cd232/html5/thumbnails/18.jpg)
Four Scenarios
• Reference (existing plants and technology)
• Distributed and savings (reduced heat demand
and local production of heat)
• Increased heat marked (conversion of natural
gas to DH)
• RE, savings and conversion (combination with
energy savings and conversion of natural gas)
