It is the policy of the Efficient Use of Energy Act that public utilities, distribution cooperative utilities and municipal utilities include all cost-effective energy efficiency and load management programs in their energy resource portfolios, that regulatory disincentives to public utility development of cost-effective energy efficiency and load management be removed in a manner that balances the public interest, consumers’ interests and investors’ interests and that the commission provide public utilities an opportunity to earn a profit on cost-effective energy efficiency and load management resources that, with satisfactory program performance, is financially more attractive to the utility than supply-side resources.
