Introduction: The Project will adapt and significantly expand existing energy storage models so that they reflect data, inputs and assumptions that are relevant to the GB grid, and on the basis of this to model certain potential uses of energy storage on the GB grid. Specifically, the focus will be on:

• Energy storage used as a source for certain Balancing Services needed for grid stabilization, such as STOR, fast reserves and frequency response

• Energy storage used to reduce future needs for such Balancing Services by shaping wind power so that it presents less of a threat to grid stability, i.e. directly addresses wind power intermittency by “shaping” wind power production into flat blocks of power thereby reducing some of the grid’s need for these Balancing Services.

Objectives: The aim of the Project will be to provide useful and potentially important operational and financial insights with respect to these uses of energy storage and with respect to whether these uses of energy storage could be effective and economical as ways to address some of the key challenges that the GB grid is expected to face in the future.
