Today’s Objective

• Deep dive on an event to make sure that we have all the information that we need to evaluate the Hourly Firm product.

• This will be an active, collaborative session with BPA and the customers that is focused on the first objective.

• We will leave with a shared understanding of any additional information that may need to be developed and reviewed at future meetings.
