It had twice as many attendees as the previous one in Billund, Denmark, in 2016 and attracted representatives from several development banks, such as the German KfW, the London-based European Bank for Reconstruction and Development and the World Bank via its group member International Finance Corporation, or IFC. The photo shows the conference’s supporters and its three organisers, namely Christian Fink (second from left), Austrian research institute AEE INTEC; Thomas Pauschinger (fifth from left in the back), German research institute Solites; and  Werner Lutsch, Managing Director of the German Heat & Power Association, or AGFW for short (second from right).

“Contract market fluctuates from year to year”

Submitted by Baerbel Epp on April 17, 2018
Ole Dalby, CEO of Arcon-Sunmark2017 was a difficult year for solar district heating supplier Arcon-Sunmark based in Denmark. The collector manufacturer’s turnover dropped from Danish Krone (DKK) 457 million, or USD 75 million, to DKK 98 million, or USD 16.2 million, according to a press release published on 21 March 2018. The uncertain country’s energy policy caused a delay in the launch of new SDH projects in the second half of 2016. Consequently, pre-tax profit went from DKK 46 million (USD 7.6 million) in 2016 to minus DKK 99 million (USD 16.3 million) in 2017. “We have made the necessary adjustments. At the same time, we have invested in retaining the clear market leader position that we achieved over the years,” Ole Dalby, CEO of Arcon-Sunmark (see photo), said.

IEA Task 55: Solar District Heating Means Big Business

Submitted by Baerbel Epp on May 23, 2017
Task 55Solar district heating is attractive business. Not only does this become obvious when looking at the 347 MWth of newly installed SDH capacity in Denmark in 2016, but also when one hears about Big Solar, a 250 MWth collector field – with 1.8 million m² of seasonal storage – planned to cover 20 % of the energy demand in the Austrian city of Graz by 2020. It certainly explains the high interest in international research platform Towards the Integration of Large SHC Systems into DHC Networks, or Task 55 of the IEA Solar Heating and Cooling Programme. “We welcomed 33 participants from eight countries during our second project meeting in Aalborg in mid-March, and even had to limit the number of participants per company because of the huge demand,” explained Sabine Putz, Operating Agent of Task 55 and COO and Head of R&D at S.O.L.I.D.

Denmark: New Solar District Heating World Record

Submitted by Baerbel Epp on January 26, 2017
SilkeborgThe Danish town of Silkeborg now holds the record for having the world’s largest solar heating system. The SDH plant of 156,694 m² (110 MWth) came online as scheduled in December 2016 after only seven months of construction. Municipal utility Silkeborg Forsyning intends to use the harnessed solar energy to meet 20 % of the annual heating demand of the 21,000 plant-connected users. The solar field was divided into four subfields to make it possible to set up the installation and hydraulics systems on this irregularly shaped piece of land (see photo). The former record holder is another installation in Denmark, in Vojens, boasting 70,000 m² (48.90 MWth) of installed solar thermal capacity. Both plants were turnkey deliveries from Danish collector manufacturer Arcon-Sunmark.

Gleisdorf Solar 2016“Large-scale solar thermal systems in the GW range – an insignificant niche market or the future for solar thermal?” was the official title of a panel discussion at the Gleisdorf Solar conference in Austria in early May. The most important question was: What will be next for the planned 350 MWth solar district heating system called Big Solar in the Austrian city of Graz? “The challenge was to adapt the Danish district heating solutions to Austrian conditions,” emphasised the project’s initiator, Christian Holter (right), Managing Director of S.O.L.I.D. Meanwhile, Christian Stadler (left), Managing Director of one of Arcon-Sunmark’s subsidiaries, Arcon-Sunmark Germany & Austria, represented the company that has stated his own interest in realising Big Solar.

Austria: Big Solar – EUR 200 Million Investment in Graz

Submitted by Baerbel Epp on April 15, 2016
Kleine ZeitungThe Austrian municipality of Graz is preparing for the post-fossil fuel heating era: On 27 February, the front page of national newspaper Kleine Zeitung (copies sold each day: around 300,000) read “Graz plans largest solar storage worldwide”. According to the news article, regional energy provider Energie Steiermark and Austrian solar thermal system supplier S.O.L.I.D conducted a feasibility study for a huge solar district heating plant called Big Solar – with promising results. The study and the news article both references the world’s largest collector field in Danish Vojens with 70,000 m² (49 MWth) as a successful example of how to undertake such a large project. At the beginning of April, Energie Steiermark confirmed the plans for Big Solar’s realisation in a press release about 2015’s annual financial statement. 

Austria: Up to 500 MWth for District Heating in Graz

Submitted by Baerbel Epp on August 7, 2015

Graz, the capital of one of Austria’s federal states, Styria, and a city with a population of 276,000, is planning to increase the share of solar thermal in its district heating grid by 20 %. The regional utility Energie Steiermark and the Austrian turnkey provider S.O.L.I.D. agreed in June to carry out a feasibility study for a collector field of up to 500 MWth with a matching seasonal storage. The proof-of-concept study will be a joint project of regional energy providers, S.O.L.I.D. and outside specialists. The photo shows the four collector fields with a total of 7,400 m2 partially belonging to the AEVG, the municipal waste disposal company in Graz, operating since 2007, and to Energie Steiermark, operating since 2014.
