St. Vrain nuclear <br />power generation. <br /> <br />For this study, each utility considered up to three alternatives for future generating <br />units: a base load coal-fired unit, a combined cycle unit, and a combustion turbine <br />(CT) unit. Any unit already planned by a utility was prespec[fied in the expansion plan. <br />The costs for generation resources provided by the individual utilities using 1987 price <br />levels ranged from $1,270 to $1,650 per kW for coal, $297 to $550 per kW for CTs, and <br />$500 to $600 per kW for combined cycle units. <br /> <br />2.2.3 Economic and Financial Parameters <br /> <br />The economic and financial parameters assumed in the study have an important effect <br />on the results. Since the utilities' expansion plans were so sensitive to the price <br />escalation rates used, the Technical Steering Committee (TSC) agreed to use the <br />Data Resources Inc.' escalation rates for coal, gas, and oil, and a general implicit <br /> <br />, Data Resources Inc., The Data Resources U.S. Long-Term Review, Winter 1987-88. <br />2-6 <br />
