Denmark: Shows Yields of More Than 40 Solar District Heating Plants

Submitted by Baerbel Epp on September 3, 2014
solvarmedata mapThe interactive map on, a website operated by agency Easynet, shows yield information entered by more than 40 solar district heating companies. The data also includes the irradiation figures and for most plants, even the hourly results of past years. The website was the brainchild of Per Kristensen, who came up with the idea when he was director of Braedstrup Fjernvarme. The screenshot shows the website’s first page.

Denmark: 23 MWth Cover 55 % of Heat Demand of 1,500 Households

Submitted by Baerbel Epp on July 28, 2014
MarstalThe new seasonal pit heat storage Sunstore 4 is at the heart of Marstal´s extended solar district heating network. The town on the Danish island of Aeroe receives 55 % of its heat from the 33,000 m² of solar collectors. The pit heat storage installation, the first of its kind, was a difficult undertaking - the team had to cope with heavy rainfalls in the summer and a thick layer of ice in the winter of 2012, when the underground storage was still not covered. June 2014 was the official end of EU project Sunstore4, which contributed EUR 6.1 million to the extension and the monitoring of Marstal´s district heating plant, but work will go on. Marstal Fjernvarme now hopes to receive support from the Danish government.

Denmark: From Sunmark to Sunmark Solutions

SunmarkBecause of a lack of turnover, Danish collector manufacturer and turnkey solar thermal system supplier Sunmark had to file for bankruptcy on 10 February 2014. “We had had a hard time with the competition during public tenders, but also some difficulties with bad quality products from Danish and Swedish subcontractors, which had created some huge costs to Sunmark,” Hans Grydehøj, CEO, co-founder and one of the two shareholders of Sunmark, explains. “In the end, it was not possible to come to an agreement with the bank, and filing for bankruptcy was the only solution.” The photo shows a district heating plant installed in the Danish town of Oksbøl in 2010.

Chile: President Inaugurates Solar Field with 27.5 MWth

Submitted by Baerbel Epp on November 13, 2013

In the middle of October, Chile´s President Sebastián Piñera inaugurated the currently world´s largest solar thermal field with 27.5 MWth (39,300 m² of collector area). The system supplies heat to the Gaby copper mine of state-owned mining company Codelco. It is located in the high central desert, 100 km south of the town of Calama, in a region where it hardly ever rains. The mining installation’s size surpasses the 36,000 m² plant in Riyadh, Saudi Arabia, which was finished at the end of 2011. “The solar field will replace underground fuel sources which pollute the environment and are expensive compared to a source that is abundant, clean and guaranteed,” Piñera said at the inauguration according to an article in the Latin American Herald Tribune from 15 October 2013. Codelco profited from fixed energy prices, so the company could plan ahead without having to worry about market fluctuations, the president added.

Europe: Grid Integration Poses Challenge for Solar District Heating

Submitted by Baerbel Epp on May 16, 2013

The first conference “Solar District Heating – Technical solutions, urban planning and business models” took place in the Swedish town of Malmö on 9 and 10 April 2013. It brought together 120 participants from 19 countries: manufacturers, district heating companies, scientists and industry associations. Examples from Sweden made clear that it is not easy to integrate solar heat into a system which has not been designed for it. The main topics in the presentations from Sweden were operation issues and the question what is a fair price for solar heat. But an ongoing discussion in Germany illustrates that the integration of solar into district heating networks also has strong economic and political elements. The photo shows the conference participants visiting a solar plant operated by E.ON Sweden in the Western Harbour of Malmö.

Norway: Solar Collectors Support District Heating

Submitted by Baerbel Epp on February 11, 2013

In November 2012, the Norwegian power supplier Akershus Energi celebrated the inauguration of its new 13,000 m² solar district heating plant in the town of Lillestrøm close to Oslo. Built by Danish company Sunmark, it is the largest solar thermal plant in Norway to date. The plant is to deliver 20 to 30 % of the heat required by the district heating network during the summer time. All year round, it is to produce 4.2 GWh of solar heat (323 kWh/m² of collector area), which equals little more than 3 % of the network’s total heat supply.
