Export Transmission Service Tariff Study (SE-94)

The Ontario Energy Board (OEB) has concluded that there is a pressing need for a comprehensive Export Transmission Service (ETS) tariff study as part of their decision on Hydro One�s 2011 and 2012 transmission rates review (EB-2010-0002). The IESO is undertaking this new study which will identify a range of proposed export tariff designs and rate scenarios, and examine the pros and cons of each scenario for analysis.

The Export Transmission Service (ETS) tariff is a charge applied to each Megawatt-hour (MWh) of electricity exports to recover the costs of transmission.

The results of the study will permit the OEB to carry out an informed review and assessment of the market and operational benefits attributed to different ETS tariff options and values.

This initiative may be of interest to all wholesale market participants and stakeholder groups; in particular, transmission customers, generators and wholesale consumers directly involved in performing export, import and wheel-through transactions. We encourage all stakeholders, or their representatives, with an interest in this matter to participate in the process, including OEB staff.
