  • Distributed PV reaching “grid parity” in some markets Economics of distributed PV for self-consumption improving rapidly Difficult to quantify deployment – further monitoring needed Residential solar PV LCOE vs. average retail power prices (variable tariff) USD/MW USD/MWh 450 400 350 300 250 200 150 100 50 Average residential electricity price (variable tarif f ) 0 2010 Residential solar PV, LCOE estimates: 2011 Germany 2012 Italy 2013 California Examples correspond to Southern Germany, Southern California and Southern Italy. LCOEs use average residential system costs (include VAT and sales tax in California and Italy where they are applicable) and do not include financial incentives; ranges represent differences in financing costs and full load hours. The variable component of residential electricity prices calculated from average annual household electricity prices and estimation of fixed and variable components as reflected on a household electricity bill. In Germany and Italy, variable component is estimated at 91% while in California variable tariffs account for 99% of the bill. 2012 electricity prices are taken as proxy for 2013 in Germany and Italy where data not yet available. 2013 prices in California based onOECD/IEA 2013 1Q2013. ©

Assuming efficiency improvements and further electrification of buildings, industry and transport Not always least cost, but affordable options Footprint, variability and convenience issues Three broad categories of situations: Sunny and dry climates, where CSP dominates Sunny and wet climates, with PV backed by hydro Temperate climates, with wind power and PV backed by hydro, pumped-hydro and H2-NG plants © OECD/IEA 2010
