WAC 194-37-100   Additional documentation of improved efficiency from production facilities.  (1) A utility will measure production efficiency improvements as the fraction of fuel savings achieved by the utility. The percentage reduction in fuel use per kilowatt-hour will be applied to the annual generation to determine the amount that is to be reported as conservation.

     (2) A utility that includes production efficiency improvements in its annual report pursuant to RCW 19.285.070 shall document the electricity savings for each generating unit with the following information certified by a registered professional engineer licensed by the Washington state department of licensing:

     (a) The first twelve-month electricity savings that the utility is counting towards its biennial target;

     (b) A description of the efficiency improvements made to the generating unit;

     (c) Annual fuel use for three preceding years, in quantity units and million British thermal units;

     (d) Annual electrical output for three preceding years, in kilowatt-hours;

     (e) The amount of capital investment and/or annual operating expenditure associated with the efficiency improvements;

     (f) The cost-effectiveness analysis prepared by the utility in planning the efficiency improvement(s);

     (g) Any post-retrofit analysis prepared by the utility in evaluating the performance and/or cost-effectiveness of the efficiency improvement(s);

     (h) A simple calculation showing the fuel use per kilowatt-hour before the efficiency improvement, the fuel use per kilowatt-hour after the efficiency improvement, and the amount of energy conservation being reported as the product of the percentage improvement in fuel use per kilowatt-hour and the number of kilowatt-hours generated; and

     (i) If efficiency improvements are installed at the same time as pollution control equipment that may itself affect efficiency, the utility may provide documentation of the effect of the efficiency improvements alone on the fuel consumption per kilowatt-hour of the production facility. In this situation, the utility shall provide a description of the changes made, the capital cost expended for both efficiency changes and pollution control equipment, and an analysis of the impact of each on the fuel use per kilowatt-hour of the production facility.

     (3) Improvements that are included in the list of measures approved by the regional technical forum and listed on the planning, tracking and reporting web site need not carry the certification of a professional engineer and may instead use the savings deemed by the regional technical forum.

     (4) A utility shall not count towards its biennial conservation target the results from efficiency improvements made to hydropower facilities that are qualified incremental hydropower efficiency improvements and are counted towards any utility's renewable energy targets under RCW 19.285.040 or 19.285.050.
