20-7-105. REASONABLE RATES.

Every rate made, demanded, or received by any utility, or by two or more utilities jointly, shall be just and reasonable. Rates shall not be unreasonably preferential, unreasonably prejudicial or discriminatory, but shall be sufficient, equitable and consistent in application to a class of consumers. To the maximum reasonable extent, the Commission shall set rates to encourage energy conservation and renewable energy use. Any data as to reasonableness should be resolved in favor of the consumer.
