6. Productivity

D.98-04-059 directed customers to demonstrate productivity by assigning a reasonable dollar value to the benefits of their participation to ratepayers.
(D.98-04-059 at 34-35.) The costs of a customer's participation should bear a reasonable relationship to the benefits realized through its participation. This showing assists us in determining the overall reasonableness of the request.

IAG submits that its participation resulted in a $2.4 million capital reduction which was the amount requested for the one aspect of the Lundy Project. IAG also alleges that its participation resulted in protecting ratepayers from paying for consequential costs flowing from the project.

After the reductions and adjustments we have listed above, the remainder of IAG's efforts has been productive, will most likely result in future cost-savings benefits to ratepayers and should be compensated.
