Whenever the commission, after a hearing upon its own motion or upon complaint, finds that the rates, tolls, fares, rentals, charges, or classifications demanded, observed, charged, or collected by any public utility for any service, product, or commodity, or in connection therewith, including the rates or fares for excursion or commutation tickets, or that the rules, regulations, practices, or contracts affecting such rates, fares, tolls, rentals, charges, or classifications are unjust, unreasonable, discriminatory, or preferential, or in any way violate any provision of law, or that such rates, fares, tolls, rentals, charges, or classifications are insufficient, the commission shall determine the just, reasonable, or sufficient rates, fares, tolls, rentals, charges, rules, regulations, practices, or contracts to be thereafter observed and in force and shall fix the same by order. In making such determination, the commission may consider current, future, or past test periods or any reasonable combination thereof and any other factors which may affect the sufficiency or insufficiency of such rates, fares, tolls, rentals, charges, or classifications during the period the same may be in effect, and may consider any factors which influence an adequate supply of energy, encourage energy conservation, or encourage renewable energy development.

(b)
If the commission considers factors which encourage renewable energy development, it shall also make findings and give due consideration to the effect of such factors on the utility's ability to recover its capital and operating costs.
(2)
(a)
The commission has the power, after a hearing upon its own motion or upon complaint, to investigate a single rate, fare, toll, rental, charge, classification, rule, contract, or practice, or the entire schedule of rates, fares, tolls, rentals, charges, classifications, rules, contracts, and practices of any public utility; and to establish new rates, fares, tolls, rentals, charges, classifications, rules, contracts, practices, or schedules, in lieu thereof.

As part of any inquiry or investigation into rate structures of regulated electric utilities undertaken on or before July 1, 2009, the commission shall consider whether to adopt retail rate structures that enable the use of solar or other renewable energy resources in agricultural applications, including, but not limited to, irrigation pumping.
