Our review demonstrates that no jurisdiction currently provides a comprehensive regulatory framework for energy storage, with the majority of jurisdictions currently allowing storage to be defined as “generation” for the purposes of licensing and other regulatory requirements.
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; and whilst battery technologies are receiving the bulk of industry attention at present, a range of technologies have been, and are due to be, installed, pumped hydro storage in particular.
Energy storage may be used in a range of project types, including standalone, co-located, and behind-the-meter projects. Standalone energy storage projects are increasingly utility-scale installations. For example, a battery array can provide a range of services, including ancillary services, to the system operator or network owner.
The majority of energy storage devices employ a direct current (DC) interface. Therefore, a PCS is required to integrate with the alternating current (AC) power grid. The purpose of the PCS is to provide bi-directional conversion and electrical isolation.
In these projects, the energy storage technology will be developed alongside a generation facility. An example of a co-located project could be a solar park developed alongside a battery; in times of high generation or low energy prices, the battery can store the solar-generated power, to be exported later, at the evening peak.
