On September 28, 2017, the Ontario Energy Board (OEB) released
its Decision on Hydro One's transmission
revenue requirement for 2017 and 2018. For the most part, the OEB
accepted Hydro One's forecasts and requests, although there are
a number of areas where there are differences.
Background
Hydro One is the largest electricity transmitter in Ontario (by
far), and its OEB-approved costs account for the large majority of
the amounts recovered in the OEB-approved "Uniform Transmission Rate." In May 2016,
Hydro One applied for approval of its transmission revenue
requirement for 2017 and 2018, on a cost-of-service basis. All
aspects of the case were addressed through a lengthy discovery,
oral hearing and argument process. The OEB's findings and
determinations are set out in a 118 page Decision addressing each of the issues raised
during the proceeding. While the precise impacts of the OEB's
determinations will not be known until a Rate Order is approved, it
is clear
