TASK AUTHORIZATION <br />d. Name of generation resource and purchase power contracts, unit ratings, full <br />load heat rates, forced outage rates, fuel types, and emission rates for SOz, <br />NOx and COz <br />e. Monthly average fuel prices by fuel type in $/mmBtu & monthly average <br />emission rates for SO2, NOx and COz in $/ton <br />f Hourly market prices for the study period <br />g. Existing and future annual interest and debt rates <br />h. Most recent balance sheet <br />i. Latest Integrated Resource Plan <br />j. Projected monthly demand and energy rates and projected Client billing <br />demand and energy determinants <br />k Copy of the existing contract or tariff between GRE and the Client <br />I. Annual projection of transmission services and ancillary charges on a per unit <br />basis <br />m. Projection and explanation of transmission congestion charges over the study <br />period <br />3. The Consultant will review the data, model, and projections provided by Connexus and GRE. <br />Based on assumptions provided to GRE by the Client, GRE will prepare projections of power <br />costs for the Client. <br />4. The Consultant will prepare a list of the principal considerations and assumptions for the <br />Client's review and approval. <br />5. The Consultant will prepare a 10-year independent projection of the Connexus and GRE <br />system power supply costs using a model prepared by the Consultant. <br />6. The Consultant will prepare a 10-year projection of the Client's costs of purchase power for <br />(i) a base case that will assume the Client continues to purchase power from its existing <br />supplier and (ii) up to three (3) alternative power supply portfolios based on information that <br />the Client obtains from CMMPA. It is assumed that the information from CMMPA will be <br />complete and include basic projected power supply planning rates for each resource in the <br />portfolios on a fixed ($/KW-mo.) and variable basis ($/MWh). The projections provided by <br />CMMPA will include the cost of transmission services and CMMPA's explanation the <br />congestion pricing included for each resource/portfolio. <br />7. The Consultant will prepare a 10-year projection of the Client's costs of purchase power <br />from Connexus/GRE and the CMMPA proposals. The Consultant will prepare a comparison <br />of the projected costs for purchase power including the cost of transmission services on a <br />nominal and net present value basis. This comparison of projected costs will be documented <br />in a brief letter report that will include a list of the principal consideration and assumptions. <br />RiverlTA-ELKRIVER071111.DOCx page2 <br />
