November 26, 2020	The OEB has issued two letters providing guidance to distributors to support the efficient and timely connection of customers with Distributed Energy Resources (DER) projects. The letters reflect recommendations and advice from the DER Connections Review Working Group. One of the letters provides clarity on the information that should be exchanged between DER proponents and distributors at the preliminary consultation stage of a DER connection project. This information will assist proponents in determining if it is feasible to proceed to the connection impact assessment stage of their project. The second letter provides information for distributors to aid discussions with prospective DER proponents in relation to a sample protection philosophy for use with connection projects intended for self-supply that use non-exporting, inverter-based technologies.
