NAC704.922. Technical appendix to resource plan.

     1. A utility’s resource plan must include a technical appendix. The appendix must contain sufficient detail to enable a technically proficient reader to understand how the resource plan and its forecasts were prepared and to evaluate the validity of the assumptions and the accuracy of the data used, including, without limitation, a list of the major assumptions used, a description of the forecasting methods employed and a description of the software utilized.

     2. The appendix must contain sufficient information to enable a technically proficient reader to reproduce the results from the computations shown, including, without limitation:

     (a) Citations to the sources of all significant information used in the resource plan.

     (b) Descriptions of all data inputs to the models used in developing the resource plan accompanied by an explanation of any modifications made to the data.

     (c) Characteristics of the generation operation of the utility, including the:

          (1) Rates of forced outages;

          (2) Rates of scheduled outages;

          (3) Heat rates;

          (4) Rates at which pollutants are emitted;

          (5) Controls required to mitigate pollution at planned facilities and estimates of the costs of those controls; and

          (6) Projections for the availability and price of fuels.

     (d) Output characteristics or profiles of renewable resources for each type of renewable resource that is being considered as a resource option or that is currently owned or under contract with the utility.

     (e) A summary of the impact of intermittent energy resources on the electric system of the utility.

     (f) The final results derived from the models.

     (g) Documentation of all models and formulas used consistent with any proprietary requirements imposed upon the utility by outside suppliers of the models.

     (h) Such other information as is necessary to enable an informed reader to examine the resource plan and verify the adequacy and accuracy of the data, assumptions and methods used in developing the resource plan.
