RE needn't break networks – IEA

The study calculates that power prices on the German network could be cut by 2.2%

Wind and solar generation can be integrated into power networks at minimal cost – provided that systems are sufficiently flexible and the process is properly planned, according to a new study from the International Energy Agency (IEA).

The Paris-based body said rapidly-growing deployment of variable renewables has inevitably asked questions of existing power systems, and their ability to adapt and operate cost-effectively.

Its new study The Power of Transformation - Wind, Sun and the Economics of Flexible Power Systems concludes that integrating the first 5-10% of variable renewable energy (VRE) generation poses no technical or economic challenges, as long as conditions such as uncontrolled local “hot spots” of renewable deployment are avoided.

And it confirms that integrating high shares – 30% of annual electricity production or more – of wind and PV can come at little additional long-term cost.
