Cost Allocation and Rate Pool Revenue Requirement
Hydro One filed evidence on the Export Transmission Service (ETS) rate in its application for electricity transmission and distribution rates and other charges for the period from January 1, 2023, to December 31, 2027.
Many intervenors argued for a substantial increase in the ETS. Mr. Chapman was the lead IESO witness to provide market pricing and system impacts of changes to the ETS and recommended no increase to the ETS. As a result of evidence provided by Mr. Chapman and IESO staff to intervenors and the OEB, the commissioners decided to (slightly) reduce the ETS rate, ensuring that the charge would not result in any unnecessary reliability and system costs.
* This work was done prior to Mr. Chapman’s role at Brattle.
