LIP A Data Request 13
IIPA Data Request 13
Please provide a copy or copies of the Company's Jursdictional Allocation
Model (in a maner similar to that of Exhbit 2 Tabs 1,2 and 10) stating the Idao
Jursdiction without Monsanto and the Monsanto load as two separate
jursdictions.
Response to lIP A Data Request 13
The Company has not performed the requested analysis. The Jursdictional
Allocation Model was designed to allocate costs to states based on allocation
factors derived from jursdictiona load. By simply isolating Monsanto's load,
system-allocated costs would be broken out between all other Idao customers
and Monsanto. The Jursdictional Allocation Model canot split Idaho situ costs
(such as curent and deferred taes, and general plant related costs) and assign the
appropriate share to Monsanto as occurs in the cost of service study. The
information contaned in the cost of service model is at a lower level of detal to
appropriately split these costs between customer classes with Idaho.
