# §905.33. Extension formula.

- (a) The amount of power to be extended to an existing customer shall be determined according to this formula:

  Customer Contract Rate of Delivery (CROD) today/total project CROD under contract today × project-specific percentage × marketable resource determined to be available at the time future resource extensions begin = CROD extended.

- (b) Where contract rates of delivery vary by season, the formula shall be used on a seasonal basis to determine the extended power resource. A similar pro rata approach shall be used for energy extensions.
- (c) Determination of the amount of resource available after existing contracts expire, if significantly different from existing resource commitments, shall take place only after an appropriate public process.
- (d) The formula set forth in [paragraph (a)](#a) of this section also should be used to determine the amounts of firm power subject to withdrawal at 5-year intervals after the effective date of the extension to existing customers, except that the percentage used would be up to 1 percent for each of the two withdrawal opportunities, and the formula would use the customer CROD, project CROD and the resource under contract at the time.
