1 Stable & low heat prices based on 25 years of experience with large scale solar thermal systems Solar process heat for the mashing process of a brewery in Austria and the electro-winning process of a copper mine in Chile Christian Stadler, Arcon-Sunmark SHIP conference in Montpellier, Dronninglund, 26 MW, m² 1

2 Your need are long term safe and reliable energy prices Solar thermal in grids and for industrial processes Invest and cost reliability Easy in operation and maintenance CO2-neutral (lowers the primary energy factor) Heat storage Allow more flexible use of CHP systems (power operated) Ensures temperature stability and accuracy to the process Arcon-Sunmark 65 large plants between 1 and 50 MW operating in Denmark for up to 27 years Arcon and Sunmark are supplying solar thermal systems for more than 40 years in more than 10 countries and we grew with our customers demand. Over time we installed 560 MW ( m²). Grenaa, 8,8 MW, m²

3 The current world biggest system is supplying half of the heat demand of Vojens, DK. Vojens, DK: Solar system: 49 MW, m² aperture area Storage: m³ water pit storage with 50/70 cm of floating insulation as cover. Storage temp. at end of summer: 90 C Annual yield: MWh Heat cost: 42 /MWh (2% Zins, 25a, no subsidy) CO2-saving: ton/year Power driven operation of CHP 3

4 Arcon-Sunmark is part of the global VKR group The yearly turnover in 2014 was 2.2 bln VKR Holding is a limited holding and investment company whose objective is to create value through capital investments and company ownership. In total, VKR Holding's companies employ some 13,500 people in more than 40 countries. VKR Holding owns companies which bring daylight, fresh air and a better environment into people's everyday lives. VKR Holding is a company in family trust ownership with the foundation VILLUM FONDEN as its majority shareholder. 4

5 Solar thermal provides security! 25 years low and stable heat costs Up to 50% solar fraction in district heating Up to 90% is reasonable for industrial processes /MWh is typical heat cost 25 years Arcon-Sunmark experience on large scale plants 5

6 Gösser brewery m² solar plant integration 6

7 Gösser brewery in Austria Successful integration of a solar thermal plant into the process Installation & performance data Collectors area: m² gross area 100 panels of 15 m² each Solar thermal storage tank: 200 m³ Key figures Integration into mashing process. Share in annual heat demand: 30%. Operation temperature C Start-up: June

8 Process & scheme Heat supply into the mashing process was changed from steam to hot water heating New heat exchangers necessary (picture) Therefore lower temperature demand and good opportunity for solar integration Process is running 3-4 days a week 200 m³ tank can just take 2 days solar prod. Additional demand added to use that energy (heating the water inlet for the biomass plant) 8

9 Summary and lessons learned The energy production is significantly higher than expected Customer is very satisfied with the solar yield The performance of the solar system is higher than calculated Some points have been learned while doing it. Custo er has today i tegrated the solar syste i to its daily life They are currently installing a brewer grain biogas system. Because of that the whole heat process is currently under redesign and will integrate the solar energy even more in the future. 9

10 Why solar is a good fit for mines: Pampa Elvira Solar project - Codelco 10

11 Local partner Develop, implement and operate energy projects. Executive team with vast experience in energy projects development and operation. Chilean investors with successful track record on several industries: Owners of largest Coca-Cola s bottler in South America. Investments in Finance industry, Health, Construction, Shopping malls, Telecom, Hotels, Energy, among others. 11

12 Local partner Guayacan Power Station 12 MW, run-of-river Operating since 10/2010 Registered on CDM 12

13 CODELCO Main copper producer in the world Controls around 10% of the world reserves. More than US$30 billions in assets. In 2012, produced 1.75 million metric tons of refined copper (10% of world production). 8 operations throughout Chile. Gabriela Mistral Division of Codelco bidded for solar heat to EW process. 13

14 The mine Ga riela Mistral 120 km from nearesty city and 2,660 m.a.s.l metrics tons of copper produced in First operation using only autonomous trucks to haul mineral. Gabriela Mistral Women account for 23% of the staff (Mining industry average: 6%). 14

15 Very harsh weather conditions at site Desert conditions. 140 km/h (87 mph) - Swirling winds. Dust. Hails / Snow. Extreme night/day temp variations: -15 C 30 C (5 F / 86 F). Earthquakes. No water. 15
