Purpose

We invite stakeholders to provide their feedback on the Transmission Reinforcement Payment (TRP) and Amendments for the Connection Process (ACP) proposed ISO tariff Terms and Conditions revisions via the following stakeholder feedback form by end of day September 4. 

Feedback is limited to ensuring we have accurately reflected the design and changes we have previously engaged on. Thank you for your input.
