Increasing flexibility is inevitable in power systems with high shares of wind and solar energy. The key is to choose the optimal sources of flexibility. The winning technology is cost-effective and able to cover long periods of low wind and solar output.

In the first part of this article, we described the urgent need for a new approach in the design and operation of power systems. We showed that flexibility is a fundamental contributor in finding a harmony between the three cornerstones of Smart Power Systems – reliability, affordability and sustainability. In many markets, the need for increased flexibility is created by rapidly growing shares of renewable generation (RES). In this second part we use recent publications of the International Energy Agency (IEA) to compare costs and the technical potential of different sources of flexibility.
