(1) The goals of these default supply resource planning and procurement guidelines are to:

(a) facilitate a DSU's provision of adequate and reliable default electricity supply services, stably and reasonably priced, at the lowest long-term total cost;

(b) promote economic efficiency and environmental responsibility;

(c) facilitate a DSU's on-going financial health;

(d) facilitate a process through which a DSU identifies and cost-effectively manages and mitigates risks related to its obligation to provide default supply service in a retail choice environment;

(e) foster an environment in which meaningful retail customer choice and workable competition can develop, where feasible; and

(f) build on the fundamental rate making relationship between the commission and the DSU to advance these goals.
