Title: Flexibility in 21st Century Power Systems (Fact Sheet)

Flexibility of operation--the ability of a power system to respond to change in demand and supply--is a characteristic of all power systems. Flexibility is especially prized in twenty-first century power systems, with higher levels of grid-connected variable renewable energy (primarily, wind and solar). Sources of flexibility exist--and can be enhanced--across all of the physical and institutional elements of the power system, including system operations and markets, demand side resources and storage; generation; and transmission networks. Accessing flexibility requires significant planning to optimize investments and ensure that both short- and long-time power system requirements are met.
