Flexibility options in electricity systems

Published: 22/05/2014

It is widely recognised that increasing flexibility is key for the reliable operation of future power systems with very high penetration levels of variable renewable energy sources (VRES). The starting point of this report is the understanding of the flexibility requirements for enabling the transition to such power systems. Furthermore, this report aims in providing a comprehensive assessment of the complete spectrum of flexibility options (instead of focusing on specific ones) and to identify key barriers for their deployment.

Power systems should deploy the most economic resources for provision of energy and operational flexibility. New flexibility resources will compete with flexibility capabilities of the existing system, such as network expansion, existing supply flexibility. In this report for Leonardo ENERGY, a detailed analysis of the characteristics of the key flexibility options is presented. Ecofys analyses 16 options covering five key categories of flexibility provision, i.e. supply, demand, energy storage, network and system.
