Energy storage projects include both commercial and demonstration energy storage installations in Canada, and may or may not be supported by an Initiative. The status of being either commercial or demonstration is determined by the nature of the integration of the project (e.g., if procured through or operated under standard market procedures in the region in which it is located), if the project has received financial support through an Initiative (typically characteristic of a demonstration project), and by how the project is communicated by proponents and media (e.g., if it is explicitly labelled a 'demonstration' project). In some cases, the line between commercial and demonstration projects can be blurry, and we welcome input or feedback on any projects you may believe to be improperly characterized.
As detailed in the documentation on Taxonomy, energy storage projects are divided into two main categories: grid-connected and not grid-connected. The purpose of this distinction is essentially to separate projects that are connected to transmission or distribution grids with the primary intention of providing services to the electricity grid, from projects that may or may not be connected to the grid but with the primarily intention of providing services to the owner/operator of the storage facility (e.g., storage installed by a commercial or industry organization). Residential installations of storage are not considered eligible for inclusion unless they are part of a larger microgrid or combined renewable energy - storage project proposed or operated by a non-residential actor (e.g., utility company). We again welcome feedback on any projects you find have been improperly characterized.
We have not set an explicit scale threshold for inclusion of a project in this database. Our intention in cataloguing energy storage projects in Canada is to highlight single-site, grid-connected storage installations, as well as unique and/or innovative energy storage projects with multiple/diffuse sites that may or may not be grid connected. For projects of the latter variety, each individual storage installation will not be catalogued separately, but rather included as a singular project in the database, having one location visible on the overview project map.
