Craig Morris, Petite Planète, www.petiteplanete.orgThe German energy transition, Kiev Solar and PV already close to baseload demand; will cut into baseload within decade when targets are met. Combined installed wind+PV will exceed peak demand by 25%
Craig Morris, Petite Planète, www.petiteplanete.orgThe German energy transition, Kiev Not April Fools: Renewables already increasingly cut into baseload, such as on Sunday, April 1.

Craig Morris, Petite Planète, www.petiteplanete.orgThe German energy transition, Kiev The result was negative prices at 4 pm. Good: firms benefit from low wholesale prices thanks to RE Bad: Investments in dispatchableconventional power less attractive

Craig Morris, Petite Planète, www.petiteplanete.orgThe German energy transition, Kiev Conclusions: If Ukraine has ~22GW summer peak demand, 11 GW of wind and 11 of solar in Ukraine should have similar effect Germany remains power exporter; grid stability best in EU (world?); CO2 emissions dropped again in 2011 despite nuclear phase-out • In mid-2012, Germany had 30 GW of wind and 29 of PV, each roughly equal to 50% of average demand (60-70 GW) • At 50%, RE offsets peak and medium load, lowers wholesale prices • Above that level, RE increasingly cuts into baseload • Increasingly, RE power will have to be stored or lost • PV currently makes up 5.3% of power supply, so 10% is feasible, but more will increasingly require (seasonal) storage • Countries with lots of air-conditioning (USA) have greater summer than winter peaks, so larger share of PV is possible there • Wind now makes up around 8% in Germany, ~20% easily feasible (assuming grid integration)
