Dublin District Heating System (DDHS)
What is District Heating?
District Heating (DH) are thermal energy networks that distributes hot water through insulated dual (supply and return) pipe lines to homes and business for space heating, hot water and industrial purposes. DH systems allow heat energy as distinguished from fuel to be bought and sold as a commodity.
DH systems offer advantages in terms of higher energy efficiencies and reduced consumption of energy resources. They are fully compatible with European and National policies and objectives for carbon dioxide (CO2) reduction, energy efficiency, security of energy supply, sustainability and competitiveness. DH can also offer capital cost savings and reduced operating and maintenance costs to customers.
Dublin City Council District Heating Corporate Policy
Dublin City Council has previously committed to progressing a Dublin District Heating System (DDHS), focusing on the general area of the Dublin Docklands and Poolbeg Peninsula (link to map) in numerous plans and reports.
- National Development Plan 2018 - 2027
- Dublin City Development Plan 2016 – 2022
- North Lotts and Grand Canal Dock Strategic Development Zone (SDZ) Planning Scheme 2014
- Poolbeg West Strategic Development Zone (SDZ) Planning Scheme 2019
- Dublin City Council Climate Change Action Plan 2019-2024
Reports on District Heating for Dublin
In 2006 and 2007, engineering consultants carried out a feasibility study for the development of a Dublin District Heating System. This feasibility study was partly funded by the Sustainable Energy Authority of Ireland (SEAI) and is called “District heating for Dublin Feasibility Study July 2008”.
A brochure for the “Dublin District Heating System” was published by Codema (Dublin’s Energy Agency) and gives a clear outline of what District Heating is and how it works.
“Dublin City Spatial Energy Demand Analysis – June 2015”, prepared by Codema, shows that DH feasibility is not confined to the Docklands area of Dublin city and that in fact 75% of Dublin City has heat demands suitable for DH. This is important as heat-demand mapping is always the first step and best practice in planning for DH and is recommended by all EU/UNEP guides to DH. It also shows that DH feasibility is not confined to the Docklands.
DCC engaged the services of a Danish district heating consultant who prepared the following two reports for the project;
Building on information gathered, DCC advertised on e-tenders a ‘Market Soundings’ document to solicit market feedback in order to define various aspects of the project and understand the role external parties could have. Following this exercise, and an analysis of options, it was decided to progress with a Joint Venture (JV) procurement option to assist DCC with the delivery of the project.
There are a number of reports presented to Dublin City Council’s Environmental Strategic Policy Committee (currently call the Climate Action, Environment and Energy SPC), links to the most recent reports are below;
Climate Action Fund
The Irish Government mentioned the DDHS project in the National Development Plan 2040 which was published in February 2018, included in that Plan was the establishment of the Climate Action Fund (CAF). In November 2018 it was announced that the Project was successful in achieving an allocation of up to €20 million for the DDHS. We are currently working through the validation stage of this process with the Department on a number of items.
Investment to date
DCC has already invested in elements of a district heating network in Dublin in a number of locations. (see photos)
- Under the river Liffey
- Under the LUAS on Mayor Street Upper
- Under the road beside the 3 Arena (Point Theatre) off North Wall Quay
Where do we go from here?
The National Development Finance Agency (NDFA), Codema, and recently engaged Legal Advisors are supporting the project team with preparation of documents for the procurement of a JV project partner. A Technical Advisor is being procured to support DCC with this procurement, and with the completion of the planning and licensing for the project as well as providing technical district heating and design services.
Current on-going works
Preliminary design is currently being carried out on the district heating network, building on this detailed design is also being carried out for the ‘Irish Glass Bottle’ and ‘Fabrizia’ sites within the Poolbeg West Strategic Development Zone, to help ensure these sites are district heating ready.
In order to inform this design some Site Investigation (SI) is to be carried out in the area, to provide suitable geotechnical data and specific information on items such as the location of existing underground services. Below is a report presented to the South East Area Committee on the 11th of May 2020 with maps of their locations.
Technical Details for Developers
This document outlines technical specifications which can be used as a basis for compliance with the planning condition for district heating-enablement. These specifications provide a guide to the installation requirements of all developments, including the particular standards to be adhered to.
