Stadtwerke Sondershausen
6,086 m2 solar field; 4 MWth
Stadtwerke Sondershausen
69 to 93ᣞC
Energy Utility
3 GWhth/y (492 kWh/y/m2)
District Heating
368,000 m3/y of natural gas
EPC subcontractor (engaged by the contractor Aalborg CSP)
732 ton/y of CO2
Challenge
A German energy utility, is required by law to decarbonize its local district heat network operations, while significantly reducing import of natural gas. Solar thermal is required to have a significant load coverage even in winter with poor irradiance and sub-zero climate.
Solution
TVP to deliver 12 months per year consistent heat above 80ᣞC, integrating a 1,000 m3 stratified thermal storage tank to extend energy release throughout the day. TVP integrates under the SCADA an innovative HTF anti-freeze control system, to avoid the use of glycol.
