Transcription

1 A clean power vision for the Greek islands INTERNATIONAL MEETING FOR SUSTAINABLE ISLANDS Athens, September 9th 2006 Elena Franzen - Solon Laboratories AG, Berlin

2 Overview of the presentation Presentation of Solon AG Solon Laboratories Island Project Case Study for a Greek Island 2

3 Overview part I Presentation of Solon AG Solon Laboratories Island Project Case Study for a Greek Island The Photovoltaic Industry The Company: Solon AG 3

4 The photovoltaic cell is the ideal energy conversion system... direct conversion of the most abundant source of energy to the most valuable form of energy (sunshine to electricity) technology with the lowest environmental impact very long system lifetimes very low maintenance modular: from mw to MW genuine economical benefit: no high (and unpredictable) running costs 4

5 ...and the photovoltaic (PV) industry is taking off worldwide. global PV production [MWp] 1,500 1, CAGR [ ]: 39% main growth drivers: feed-in laws rising and volatile fuel prices source: PV News, solarbuzz 5

6 Solon AG is a pioneer in solar energy... Key company facts Company founded in 1996 Largest producer of solar panels in Germany Headquarter in Berlin, Germany 540 employees (2006) Sales in 2005: 201.2M (+94%) First PV company to go public (1998) 2006 promoted to TecDAX Market capitalization (August 2006): 275M 6

7 ...and has a long and prominent track record - Parliamentary building, Berlin Zara fashion store, Cologne Audi AG, Ingolstadt Examples: installation of 70% of the solar systems of the Federal Government of Germany in Berlin construction of large PV power plants in Germany 15+ power plant projects currently under development in Spain and Italy 7

8 including world-leading projects: 12 MW tracked solar power plant Gut Erlasee 8

9 The company has set up a structure and alliances... Company Structure Strategic Alliances 9

10 profitability...that allow to focus on the attractive downstream market. Silicon Wafers Solar Cells Modules Movers Power plants strategic alliances joint ventures 10

11 Overview part II Presentation of Solon AG Solon Laboratories Island Project Case Study for a Greek Island Solon Laboratories AG Goals and approach of the island project 11

12 Solon Laboratories AG further extends Solon AG s scope... SOLON LABORATORIES AG is a separate company for advanced energy projects. SOLON LABORATORIES AG focuses on autonomous power systems combining different renewable sources (wind, solar,...) and large-scale energy storage solutions. SOLON LABORATORIES AG has strong private financial backing for investments in emerging technologies and a young and motivated team to push the frontiers for renewable energy. 12

13 ...to integrative renewable energy systems for islands... Island power grids often depend completely on fuel imports Electricity costs and system vulnerability very high Islands experience future threats to power grids already TODAY " " Islands often offer a great potential for renewable energies Tourism is the main industry on many islands EU promotes renewable energy Small islands have the great opportunity to develop today the power supply scenario of TOMORROW 13

14 incorporating new large-scale energy storage technologies. PV Wind Backup (e.g. biodiesel) Load Storage RE: from fuel savers to base power plants New technologies for large-scale energy storage can overcome the limitations of traditional storage technologies " 14

15 Suitable NaS batteries are now commercially available... (source: NGK Insulators, Japan) 10 modules Peak power: 500 kw Capacity: 3,6 MWh 500 kw unit, NGK, Japan 15

16 and a low-cost thermal storage solution is developed by Solon Labs partners. Graphite Block Generator Turbine electricity heat 2MWhth unit, LES, Australia Operation of prototype Lloyd Energy Systems (LES) in Cooma, Australia Patents and Licences acquired by SOLON Labs in 07/2006 First Prototype in Europe to be build in Austria by Solon Labs 16

17 Solon Labs has the means to make a difference.! We don t have all the knowledge either!!! but we can bring together the right people: Research facilities with experience in island grids Manufacturers of interesting storage technologies Wind generator manufacturers Biomass plant constructors Investors in renewable energy (venture capital) Local utilities and other stakeholders 17

18 Overview part III Presentation of Solon AG Solon Laboratories Island Project Case Study for a Greek Island Energy system simulation Results and recommendation 18

19 A simulation for a Greek Island... Solar Technical data Interest rate Investment costs O&M costs Wind Load Load Constraints... HOMER (NREL) Hybrid system hour-by-hour simulation and optimization Component sizes System performance Initial capital needs Cost of Electricity 19

20 ...with the following assumptions... Total consumption/peak power 6 GWh / 2.2 MW Renewable energy fraction (target setting) 95 % PV: min. 15% Life-time 20 years Interest rate (nominal) 7 % PV Wind generator Biomass generator Battery (NaS) 6 /kw 1400 /kw 780 /kw 390 /kwh /kw Additional O/H investment Fuel costs Additional O&M costs 0,8 /l /a 20

21 ...yields an optimized hybrid system 70 x 10 kw 4 x 800 kw 8 x 350 kw 2200 kw 6000 MWh Load Storage 1300 kw 9400 kwh NaS option 21

22 based almost completely (95%) on wind and solar energy. Electricity production Average wind speed: ~9 m/s Average solar radiation: ~5 kwh / day 22

23 This is more than just a fuel saver Generator output Power station operation: 730 h/year (8% of year) On average, two of eight 350 kw units are running Maximum output far below capacity security reserve Annual (bio)fuel needs: < l 23

24 this could be an economic and sustainable solution. Cost of electricity production 0,28 /kwh (for the next 20 years*) * in constant (2006) euros 24

25 Prices are stable for different scenarios... reference wind sun 90% 110% 90% 110% battery* 10 years 20 years interest rate 8% 6% fuel price 200% 50% *service life optimistic case pessimistic case 25

26 and below the current cost for electricity production. Electricity Production Costs for Medium Scale Islands (2005) * Production Costs / 0,6 0,5 0,4 0,3 0,2 0, * Pre-feasibility study for a 100% RES micro grid in a Greek island, CRES, 2006 peak demand / kw Our Goal: a business model for a renewable energy supply system for an entire island (group) 26

27 Overview of the presentation Presentation of Solon AG Solon Laboratories Island Project Case Case Study Study: for a Greek xxx Island Conclusion 27

28 The greek islands offer a big potential for a pioneering renewable energy project. Chances & benefits stable cost of electricity for the Greek islands increased political & economical independence gain of local expertise & know how raised image (globally) tourism economical benefits (jobs,...) Solon Laboratories AG would be an ideal partner technical expertise in renewable energy systems financial strength / established business network determination to make a difference 28

29 There is still much to do... Consider all legal and economic issues Consider all technical issues Set up cooperation with local stakeholders 29

30 let s do it! " " - Thank you - 30
