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, pp. 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.

TURN and UCS state that they argued for positions in this proceeding intended to reduce the total cost of RPS compliance by ensuring the development of an efficient and cost-effective renewable development market. Since no rate issues were specifically involved in these decisions, TURN and UCS argue that it would not be reasonable to require a more detailed demonstration of specific monetary benefits. We agree that to the extent an efficient renewable market lowers compliance costs, ratepayers benefit monetarily from TURN's and UCS's positions. Thus, we find that TURN's and UCS's efforts have been productive.
