Renewables drive transformation of power system
The system should be transformed completely if it is going to work, says IEA
Integrating large amounts of variable renewable energy into the energy mix is really about transforming the world’s power systems, the International Energy Agency (IEA) has said. “Integration is not simply about adding wind and solar on top of business as usual. We need to transform the system as a whole to do this cost-effectively,” the agency’s executive director Maria Van der Hoeven said at the launch of the IEA’s latest report. In The Power of Transformation – Wind, Sun and the Economics of Flexible Power Systems, the agency says that integrating high shares – more than 30% of yearly electricity production - of wind and solar photvoltaics (PV) in power systems can come at little addition
