For each generating unit, please explain how the heat rate data submitted to the CAISO was derived.

a)  Were careful measurements made at each reported generation level using special instrumentation?

b)  Were measurements made at each reported generation level using the regular station instrumentation?

c)  Where polynomial or exponential heat rate curves developed for the unit and the heat rate data submitted to the CAISO obtained from those equations?

Staff/GEN-33

a)  For each generating unit for which the heat rate data submitted to the CAISO was obtained from the unit's RMR contract, please provide a copy of the heat rate pages of the RMR contact from which the heat rate data was obtained. 

b)  If a generating unit's heat rate data was obtained from its RMR contract and was modified in any way, please explain the basis for the modification.

c)  If in accordance with the heat rate methodology in the RMR pro-forma contract, the heat rates submitted to the CAISO were inflated by 2%, please explain why it is reasonable to use inflated heat rates to calculate MMCPs in this proceeding. 

Staff/GEN-34

If only one set of heat rate data was supplied to the CAISO for a unit, please explain why that data gives reasonable results throughout the year, i.e., why were seasonal heat rate data not supplied?.

Staff/GENS-35

a)  For each generating unit, please provide the heat rate data submitted to EPA as part of the CEMS program and describe how the data were derived .

b)  If the heat rate data submitted to the EPA differs from what has been provided to the CAISO, please explain why.

c)  Is the heat rate data provided to the EPA available to the public on the EPA's web site?  If so, please provide the web address.
