After the Global Atlas (continued by IRENA), capacity building and econValue projects» successful completion in 2014, the Working Group now focusses on auctioning systems» increasing role for cost - efficient deployment of renewable energy technologies and market and system integration of rising shares of electricity
from variable renewable energy sources.
Jenkins and Trembath propose a «rule of thumb»: «It is increasingly difficult for the market share of
variable renewable energy sources at the system - wide level to exceed the capacity factor of the energy source.»
This page provides resources on topics such as operating practices, renewable energy forecasting and system dispatching that can used to understand opportunities to modify system operations to better
incorporate variable renewable energy sources and inform policy decisions.
Although variable renewable energy sources were critical to European society for some 500 years before fossil fuels took over, there were no chemical batteries, no electric transmission lines, and no balancing capacity of fossil fuel power plants to deal with the variable energy output of wind and water power.
«The growing share of
variable renewable energy sources in the electricity mix requires stable backup from flexible and sustainable energy sources, and flexible technologies such as storage and demand - response,» the ITRE said in the report.
In its current project phase, the Working Group is focusing on the increasing role of auctioning systems for the cost - efficient deployment of renewable energy technologies, as well as on market and system integration of the rising shares of electricity
from variable renewable energy sources.
Policy measures have not yet caught up with rapid deployment of electric vehicles and their possible role as an enabler for better integration
of variable renewable energy sources.
