3 Swiss Energy Strategy History 11 March 2011 Fukushima Daiichi nuclear disaster in Japan 14 March 2011 Swiss Government stops permission procedures for new nuclear power stations 25 May 2011 Swiss Government decides to move out of nuclear energy by September 2013 Energy Strategy

4 Swiss Energy Strategy Electricity 2010: Domestic electric energy consumption: 60 TWh Domestic production & consumption balanced over the year. Domestic production: 56.5% hydro 34 TWh 38.1% nuclear 23 TWh 5.4% other 3 TWh 2050-horizon assumptions: If no changes in the consumption profile: 84 TWh Economies: 24 TWh in the consumption 60 TWh (as in 2010 but with 9M) Hydro: 36 TWh New renewable energies: 24 TWh (predominantly PV and wind)

5 Electricity in Switzerland 2050 Hydro: 36 TWh (60%); other RE: 24 TWh (40%) Consumption 5000 GWh TWh (in 2050: 100% RES) Nuclear Without nuclear Hydro (dam) J F M A M J J A S O N D Hydro (flow) Other thermal Status in 2011 for non-hydro renewables: biomass =0.67% (in 2015: +) solar PV =0.24% (in 2015: ca. 2% -> factor of 10 until 2050) wind=0.11% (in 2015: +)

12 Contributions from the PV LAB at BFH Electric energy production meets consumption - Seasonal: winter electricity (from alpine PV installations) - Diurnal: morning / evening electricity (from PVOB)

13 Seasonal (winter) electric energy from Alpine PV Jungfraujoch (3 454 m asl) Installation: Burgdorf (540 m asl) Installation:

14 Alpine PV installation at Jungfraujoch, Switzerland m asl cold temperatures (mean: -7.9 C) -> solar cells work more efficiently high solar radiation high albedo (due to glacier / permanent snow) -> offer additional convertible sunlight to the solar cells

15 Diurnal electric energy (morning, evening) from PVOB Sihlweid near Zürich, Switzerland - two 60 m high tower buildings - retrofit with > 100 kwp thin film modules - on all 4 sides of the buildings - «PVOB Guidelines» (in prep.)

16 Quality control (PV modules) IR-multicopter drone BSc research thesis of Manual Lanz (2014) What? Remote-controlled inspection of PV modules - 15 min. to IR map a 560 kw PV facility Thermal imaging (thermography) - camera records infrared video at 30 frames per second / live videostream to pilot Detection of power losses / avoid fire hazards - deterioration (recognizable as hot spots)

17 Quality control (data) Swiss Energy Strategy 2050 PV is most important new electricity energy source in 2050 (12 TWh) = 20% of total electricity consumption in 2050 Swiss network of 30 PV installations operated by the PV LAB at BFH since 1990s reliability of PV installations (long-term) ageing / degradation issues cost / production ratio production meets consumption

18 Summary - Swiss Government decided on Energy Strategy 2050 (2011) - 100% renewable electricity by 2050 /60% hydro, 40% other RE - Among other RE, photovoltaics most important source (20%) - Eight Swiss Competence Centers for Energy Research (2014+) - Capacity building of new energy experts (next generation) - PV LAB at BFH Switzerland: winter electricity from alpine PV - Swiss Government: re-direction of funds towards 100% renewable energy -> leave nuclear to minimise risks -> reduce dependancy (fossil fuel) in the long term
