This Standard specifies the technical requirements for the interconnection of distributed energy resources (DER) and distribution systems up to 50 kV line to line at the point of common coupling (PCC).

1.2

This Standard does not define the maximum DER capacity or the upper voltage limit for installations that are interconnected with a single PCC or connected to a given feeder.

1.3

The objective of this Standard is to specify minimum requirements for the

(a)   safety of persons;

(b)   continuity of service; and

(c)   protection of property.

(f)    interconnection of distributed energy resources and distribution systems that are not ultimately connected to a province-wide or regional electricity grid (i.e., remote locations). The wires owner of the remote grid may apply the standard in part or whole, where appropriate for the remote grid.

1.5

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the Standard.
