Energy Storage Systems for Ancillary Services

Stationary energy storage will have a large role to play in the electricity grid of the future. Demand is being driven by several key trends, including the proliferation of intermittent renewable energy sources such as wind power and solar energy, the onset of the smart grid concept and a shift to plug-in hybrid and electric vehicles.

Energy storage systems (ESS) are being developed by technology providers in a wide range of solutions, from batteries, flywheels and mechanical storage. One key emerging area within the ESS market is the Ancillary Services sector, which includes applications such as frequency regulation, spinning reserve, voltage control, and other fast response services.

ESS systems providing ancillary services offer sustained energy requirements of typically less than one hour, and often minutes or seconds, and a response time that is often near-instantaneous. The technologies best suited to provide ancillary services are lithium ion (Li-ion) batteries and flywheels, although Pike Research anticipates that a range of technologies and configurations will compete in this market.

This Pike Research report provides an in-depth analysis of the global market opportunity for ESS-based ancillary services. It includes a detailed assessment of various energy storage technologies, their strengths and weaknesses, performance capabilities, and economics. The report also examines the commercialization path for ancillary services, including market drivers and barriers, policy and regulatory factors, and investment dynamics. It includes profiles of key market players along with detailed market forecasts, segmented by technology and world region, through 2019.
