  1. WELCOME Examples of financing solutions applied to solar heating and cooling A SHE study Brussels - 29 November 2018

  2. Solar thermal business models Ownership continuum Multiparty ownership End-user Third-party ownership ownership 2

  3. Solar thermal business models I. End-user ownership Small to medium installations (>1000 m 2 ) • • Segments: buildings & industry Often public financial assistance • 3

  4. Solar thermal business models Solar process heat for Fleischwaren Berger (Oostenrijk, Austria) 4

  5. Solar thermal business models Solar process heat for Fleischwaren Berger (Oostenrijk, Austria) 1067 m 2 flat plate collectors • 500 MWh/a – 11% solar fraction • • EUR 790 000 (total investment) 30 EUR/MWh (production cost) • 5

  6. Solar thermal business models Solar thermal in buildings (Tilburg, Netherlands) (Peter van den Besselaar) 6

  7. Solar thermal business models Solar thermal in buildings (Tilburg, Netherlands) 354 m 2 flat plate collectors & 9 m 3 thermal • storage tank EUR 272 000 (total investment) • • 162 MWh/a 7

  8. Solar thermal business models Solar thermal in Buildings (Kapfenberg, Austria) (Nussmüller Architekten ZT GmbH, 2014) 8

  9. Solar thermal business models Solar thermal in Buildings (Kapfenberg, Austria) 144 m 2 flat plate collectors & 7 m 3 layered • storage tank 39.5 MWh/a • • Thermal energy savings of 25 734 EUR/a 50 EUR/MWh 9

  10. Solar thermal business models II. Third-party ownership Energy supply contracting • Solar leasing Segments: Buildings, industry & district heating • • Trending due to accessibility to solar thermal Contract lifespan 15-25 years • 10

  11. Solar thermal business models Solar district heating in Büsingen, Germany (Solar Complex, 2012) 11

  12. Solar thermal business models Solar district heating in Büsingen, Germany 1090 m 2 evacuated tube collectors & 100 m 3 • thermal storage tank 520 MWh/a – 13 % solar fraction • 100 % solar fraction in summer 114 EUR/MWh (retail price by SolarComplex) • 12

  13. Solar thermal business models Solar process heat for the Lecta paper mill (Dordogne, France) 13

  14. Solar thermal business models Solar process heat for the Lecta paper mill (Dordogne, France) 4211 m 2 flat plate tracking collectors & 700 m 3 • thermal storage tank • 3900 MWh/a – 1%-2% solar fraction EUR 2.2 million (total investment) • +/- 20 EUR/MWh • 14

  15. Solar thermal business models Solar district heating in Hamburg, Germany (IBA Hamburg GmbH / Bernadette Grimmenstein) 15

  16. Solar thermal business models Solar district heating in Hamburg, Germany 1600 m 2 evacuated tube collectors & 2000 m 3 • thermal storage tank 22.5 GWh/a (total energy prod, w/ other RES) • • EUR 9.8 million (total investment of Hamburg Energie) 16

  17. Solar thermal business models III. Multiparty ownership Cooperatives • Public-private partnerships Segments: Buildings & district heating (& industry) • • Always some form of public entity involvement 17

  18. Solar thermal business models District heating in Marstal, Denmark 18

  19. Solar thermal business models District district heating in Marstal, Denmark 33 300 m 2 flat plate & evacuated tube collectors • 75 000 m 3 seasonal thermal storage 32 000 MWh/a (w/ other RESs) – 55% solar • fraction EUR 6.1 million for 2012-2014 extension • +/-30 EUR/MWh (production cost) • 19

  20. Solar thermal business models Helios thermal storage for solar district heating (Graz, Austria) (Energie Graz) 20

  21. Solar thermal business models Solar thermal business models Helios thermal storage for solar district heating (Graz, Austria) 2000 m 2 flat plate collectors & 2500 m 3 buffer • thermal storage • 1000 MWh/a Storage upfront cost: EUR 750 000 • Total cost: EUR 4.3 million 21

  22. Financing opportunities Main financial barriers to ST • High upfront capital costs (low economies of • scale) Perceived low accessibility to capital •  Develop financing opportunities o Role of public and private investment 22

  23. Financing opportunities Public investment opportunities • Grants • Tradable certificate schemes EU ETS & NER300/NER400 o Loans at reduced rates • Salix Finance o • Feed-in tariffs Council housing in Devon, UK o 23

  24. Financing opportunities Private investment opportunities ESCO financing • Malteries Franco-Suisse (Issoudun, France) o Crowdlending • Mondim de Basto Daycare (via GoParity) o 24
