The present Firm Power Rates became effective on an interim basis on

January 23, 1981 and are currently subject to refund pending the outcome of

proceedings before the FERC. The present Firm Transmission Rate became effec-

tive in 1974, while the present Non-Firm Transmission Rate became effective in

1965. Western expects that the effective date for its proposed CRSP Rates will

be April 1, 1983.

The Rate Brochure states that the "average annual increase in cost in

the current studies as compared to the studies run in support of the existing

rates is about $25.0 million. This increase is shown by Western as follows:
