Energy storage project registration and approval process

What is a standalone energy storage project?

A standalone energy storage project is an independent utility-scale installation that uses battery arrays to provide various services, such as ancillary services, to the system operator or network owner. This type of project enables the deferral of network reinforcement works or supports islanded networks.

Does energy storage need a regulatory framework?

Currently, no jurisdiction provides a comprehensive regulatory framework for energy storage. Instead, most jurisdictions define storage as 'generation' for licensing and other regulatory purposes.

What are the different types of energy storage projects?

Energy storage can be used in three main project types: standalone, co-located, and behind-the-meter projects. Standalone energy storage projects are increasingly utility-scale installations, such as battery arrays that provide ancillary services to the system operator or network owner.

Are there legal issues relating to energy storage?

As set out above, there are a wide variety of energy storage technologies and applications available. As a result, there are a number of legal issues to consider when it comes to energy storage projects. The relative importance of such issues will be informed by the specific project design and revenue stream requirements, such as double circuit connection.

What types of energy storage projects has CMS advised on?

CMS has been deeply involved in the development of energy storage – including advising on pumped hydro and battery standalone storage, co-located energy storage and generation developments and behind-the-meter projects.

Which energy storage technologies are being installed?

As is evident from our survey, a range of energy storage projects have been installed or are due to be deployed in the majority of jurisdictions. While battery technologies are currently receiving the most attention, a range of technologies have been, and are due to be, installed, with pumped hydro storage being a notable example.
