CONTRACT FOR 40,000 SQFT/ 3.800 m² PLANT  IN GRAZ, AUSTRIA

http://www.grazag.at/de/wasser/AndritzNEU.html


We are pleased to announce the closing of contracts for a solar plant which will supply energy to Graz District Heating  and will provide space heating for the buildings occupied by the water agency of Graz AG. 

The plant will include 40,000 square feet (3,800 square meters) of collector area.  The collectors will be mounted on the ground in an area that is used for water runoff.  Installation will begin in March, 2009 with scheduled completion in April, 2009

When the new plant comes on-line, Graz District Heating will have a total of 6.5 MW of solar thermal energy to help meet the demand in the summer months.   There is a total summer demand of 14 MW.  The current plan is to develop sufficient solar thermal capacity, which when combined with waste heat from industry and an existing small cogeneration plant, will displace all use of natural gas  boilers during the summer months.

Solar radiation during the winter months in Graz sometimes is not sufficient to produce the temperature needed for space heating.  The space heating system will include a heat pump that will allow the production of the required temperature.   The combination of a heat pump with solar thermal  for a large, commercial application is unique.  Detailed monitoring will help determine the effectiveness of the combined solar/heat pump system.

SOLID will serve as the prime contractor and will use OKotech HT collectors.  The HT collectors are specially developed to produce high temperatures (over 190 F (85C)) and will achieve better performance that most vacuum tube collectors on clear days.    The contract value is 1.5 Mio Euro.

This project was developed in partnership with the city of Graz supported both by the Mayor Siegfried Nagl and Vice Mayor Lisa Rücker, by the city owned Graz AG and the utility Energie Graz GmbH& CoKG. Attached articel shows Mr. Nagl and Mrs. Rücker in front of the latest solar plant Graz/Puchstraße.

The utility pays the same rate for solar thermal energy as it does for the energy produced by the gas boilers.   The investment is supported by the Austrian Climate Fund.   The major Styrian news paper „Kleine Zeitung" published attached report.
