XD Consulting on District Heating Study Tour in Denmark



Xavier Dubuisson from XD Sustainable Energy Consulting visited Kolding, Billund, Aarhus and Aalborg to learn from EU district heating experts and work with his SmartReFlex partners on Irish district heating projects. The study trip also included a visit to the Legoland solar district heating system in Billund.

Xavier attended the 4th International Solar District Heating  Conference which took place in Billund where he represented the EU SmartReFlex project which aims at supporting the development of 100% renewable district heating in emerging market, such as Ireland.

He then met with his SmartReFlex colleagues at the Danish District Heating Association and PlanEnergi in Kolding and Aarhus respectively, to review the case studies and feasibility studies undertaken by XD Consulting on district heating projects in Co. Kerry, Ireland.

Finally, he presented some of the heat mapping work recently completed as part of SmartReflex project at the 2nd International Conference on Smart Energy Systems and 4th Generation District Heating Conference  which was held in Aalborg on 22nd and 23rd September.

Xavier’s study visit to Denmark in the framework of SmartReFlex was a unique opportunity to get an insight into state-of-the-art smart, renewable district heating systems, and the huge contribution they make towards the decarbonisation of the energy system in Denmark. He is also very grateful to his SmartReFlex colleagues and other international experts he met along the way, for their welcome and generous sharing of expertise and know-how.

The Chisinau Sustainable Energy Information Centre, housed in the Moldovan Agency of Energy Efficiency, will serve as a hub for a number of initiatives by NGOs, businesses and education institutes, aiming to inform and educate citizens. The centre’s staff will focus on outreach activities and will be equipped with interactive exhibits, demos of sustainable energy products, and lots of information material. They will work closely with the hub members and run regular roadshows to local communities to promote country-wide awareness on energy efficiency. A strong emphasis is also given to the use of social media and digital communication to engage with younger audiences.

During the ceremony, the participants had the opportunity to interact with interactive displays and exhibits prepared for the Sustainable Energy Information Centre and to collect information materials. XD Consulting, together with local partners, provided advice and technical assistance to the Agency for Energy Efficiency to establish the centre, as part of a EU-funded project under the INOGATE programme for energy policy co-operation in Eastern Europe, the Caucasus and Central Asia.


XD Consulting promotes sustainable energy information centres in INOGATE partner countries

Xavier Dubuisson, XD Consulting’s managing director, was invited to present at a recent conference of the INOGATE programme in Moldova on 19 March 2014. The INOGATE programme is an international energy co-operation programme between the European Union and the Partner Countries of Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Tajikistan, Turkmenistan, Ukraine and Uzbekistan.

Xavier’s presentation communicated the role of Sustainable Energy Information Centres in the deployment of energy efficiency and renewable energy technologies across Europe, and reflected on his experience as technical manager of the Renewable Energy Information Office of the Sustainable Energy Authority of Ireland (SEAI). The REIO was awarded ‘Best National Renewable Energy   Partnership’ in 2004 as part of the EU Campaign for Take-Off Award. A copy of Xavier’s presentation is available here.

Solar Energy for Community Development

Xavier Dubuisson, MD of XD Consulting, was invited to give a presentation at the Solar Energy Workshop “Reviewing the status and strategy of Ireland’s Solar Industry” organised by the Tyndall National Institute in Cork last week. This event was organised by Tyndall in conjunction with the International Energy Research Centre (IERC) and supported by Enterprise Ireland through the ENIAC  FP7 project ERG (www.eniac-erg.org). The grathering and presentations demonstrated the vibrancy and quality of the research activity undertaken by Irish academic institutions and industry, and the linkage it has at international level. There was also a robust debate about the need for solar technology, in particular PV, to come out of the woods in Ireland and to be given an integral and significant part in the sustainable energy policy agenda here.

In his talk, Xavier gave an overview of XD Consulting’s work with Sustainable Energy Communities and the initial results of our Renewable Energy Roadmap project with Transition Kerry and Kerry County Council. He emphasized the rationale for solar photovoltaic energy to play a central role in community-based green energy initiatives and discussed his most recent findings on the economics of PV in Ireland – showing return on investment of at least 8% (IRR) in commercial-scale projects with conservative assumptions. With all the talk in town being about grid-parity of PV in sunnier climates (Eddie O’Connor states in his last blog that new solar PV and new coal are almost at the same price in South Africa and New Zealand), we are not far off PV becoming competitve in Ireland. Do not hesitate to contact us for details on our analysis and the services we provide in the area of solar technologies.
