Lessons need to be considered to make the German ‚Energiewende‘ a role model for Asia Issues with German Energy Transition Lessons learnt for Asia Overinvestment in Renewables through feed-in tariffs imposed long-term burdens for subsidies on electricity consumers Secure affordability of energy/electricity prices through optimized energy mix and proper market regulation Surge of electricity prices due to high Renewables subsidies and grid expansion Energy policy needs to create market mechanisms to foster investment in reliable low-carbon back up capacities Collapse of CO2 price pushed power generation to Coal again resulting in increasing CO2 emission Insufficient revenues from power-only market for conventional power plants lack of investment in reliable power generation capacity Missing incentives for required flexible gas-fired power plants for stabilization of power system Integration of record level of Renewables would require expansion of transmission grid capacity Stabilize power system through sufficient investment motivation in flexible gas-fired power plant capacity Provide adequate power transmission capacity fast enough to link renewables resources and consumer areas Coal-to-gas shift to be promoted as a huge lever for reduction of CO2 emissions (economics stimulated by a stable CO2 price) © Siemens AG 2014 All rights reserved.
