That the assumptions used in developing projected input data and the models used in the integrated resource planning process should be identified and well-documented. Utility-specific data should be used whenever possible (e.g., unit performance data, end-use load research data, market research data, etc.). In cases where utility-specific data are not available, the assumptions must be clearly defined;\n\n2. That historic data, if available, should be assessed in developing projected data. Significant departures from historic trends should be explained;\n\n3. That each projected data series should represent the Company's most current forecast;\n\n4. That computer modeling techniques should be used in the development of an integrated resource plan;\n\n5. That estimates of the capital and O\u0026M (operation and maintenance) costs of supply-side options should include realistic projections of the costs of compliance with all promulgated environmental regulations or enacted legislation from which environmental regulations will be promulgated;\n\n6. That each assumption and/or projected data series should be consistent with all other assumptions and/or projections. Consistency of data should be maintained between all models used within the integrated resource planning process; and\n\n7. That alternative projections to determine sensitivity to input assumptions should be developed. These alternative projections should be used to perform cost/benefit analysis.\n\nWaiver of strict adherence to these guidelines for small utilities or those in unusual circumstances may be granted by order of the Commission.","path":["Title 20.
