Rate Competitiveness

Tacoma Power and Tacoma Water conducted comparative rate analyses for commercial and industrial rates against those of Tacoma’s peer port cities.

The analyses were extremely complex and time consuming for both Power and Water because rate classes between utilities are different. Therefore, direct comparison is extremely difficult, so our analyses looked at system averages and other criteria to best levelize the rate structures and fees.

The good news is that both Tacoma Power and Tacoma Water are competitively priced relative to their peer port city utilities.
