Summary:The paper presents the initial results of a research project on
the technical and economic feasibility and logistics of installing a
cogeneration plant on the University of Calgary Campus in the light of
the upcoming electricity deregulation at the retail level, mandated by
the provincial government starting 1 January, 2001. Part of the electric
power generated will be used to supply the campus needs and the excess
sold to ENMAX at the prevailing competitive price. The steam byproduct
will be used to satisfy campus hot water needs. A range of sizes for the
cogeneration plant will then be determined so as to maximize return on
invested capital under the retail post-deregulation scenario, using a
range of dollar figures per kWhr above and below the estimated mean
value. The following collateral issues are also addressed: (1) siting of
the cogeneration plant; comparative merits will be evaluated along with
the appropriate recommendation; (2) gas-fired turbine? Contractual
arrangements with a natural gas supplier for protection from gas price
fluctuations are analyzed; logistics of standby diesel fuel in case of
gas supply interruption are explored; (3) relative merits of the
university undertaking this endeavor alone or in collaboration with an
operator such as ENMAX are investigated on a cost and profit-sharing
basis; and (4) contractual arrangements with ENMAX to supply emergency
power, in case of cogeneration unit failure, are also addressed. KWhr
dollar figure estimates are done for the retail post-deregulation
scenario and their impact on cogeneration assessed
