Also in the foregoing Hydro One's LTC application (EB-2021-0136), the OEB considered a request from the IESO (an intervenor) to file a reply submission to address concerns raised by APPrO (another intervenor) regarding the IESO's needs assessment process. The OEB denied the IESO's request and explained that only the applicant, Hydro One, was permitted to file reply submissions and that Hydro One was free to consider the submissions or perspectives of any of the parties in any reply submissions that it may choose to file.
