4. Contributions of Other Parties

Section 1801.3(f) requires an intervenor to avoid participation that duplicates that of similar interests otherwise adequately represented by another party, or participation unnecessary for a fair determination of the proceeding. Section 1802.5, however, allows an intervenor to be eligible for full compensation where its participation materially supplements, complements, or contributes to the presentation of another party if that participation makes a substantial contribution to the Commission order.

CARE intervened because of its concerns with environmental and economic impacts that the power plant will have on the community and argues that its participation was unique and was not duplicated by other parties' efforts. We affirm that CARE did not duplicate the efforts of other parties'.

After we have determined the scope of a customer's substantial contribution, we then look at whether the amount of the compensation request is reasonable.
