Please review Section 5 for information about interconnection requests submitted prior to the effectiveness of these new procedures.

The new procedures are posted under ANPP Valley Transmission System in the Large Generator Interconnection folder to the left.

October 2, 2009

On October 1, 2009 SRP increased the TTC on the Coronado to Silverking 500 kV line from 1133MW to 1382 MW. The increase in TTC is a result of transmission upgrades in anticipation of SRP’s construction of Springerville 4. The upgrades include shunt capacitors in the valley and series compensation on the Coronado to Silverking 500kV line.

NEW SUGARLOAF TRANSMISSION

On July 20, 2009 the new SRP Sugarloaf 500kV Substation was energized to the APS 69kV system. The Sugarloaf Substation bifurcates the SRP Cholla to Coronado 500kV line. As a result of the bifurcation and the tie into the APS system, studies were performed to determine the bidirectional TTC ratings of the new Cholla-Sugarloaf and Sugarloaf- Coronado 500kV lines.

Cholla-Sugarloaf 496 MW

Sugarloaf-Coronado 477 MW

Coronado-Sugarloaf 171 MW

Sugarloaf-Cholla 110 MW

No later than 1600 MST on July 31, 2009 SRP will adjust existing paths to include Sugarloaf as well as post new paths that use Sugarloaf as a POR or POD. None of these changes will have any impact on customers holding reservations across the Cholla to Coronado 500 kV line or the Coronado to Cholla 500 kV line.

ELDORADO SYSTEM: MEAD 230-ELD230-ELD500-MOH500 TRANSMISSION AVAILABILITY

SRP is offering 158 MW bidirectional Point-To-Point Transmission Service on the Eldorado System, which is comprised of Mead 230-Eldorado 230-Eldorado 500-Mohave 500 paths, each of which can be a Point of Receipt and/or a Point of Delivery.

SRP will sell up to 158 MW on the Eldorado System in monthly and yearly increments beginning on July 1, 2009, through regular OASIS postings and procedures. SRP will accept Transmission Service Requests for service for September 2009 through July 2010.

Transmission Customers may directly contact Mike Pfeister at 602-236-3970 for service requests for July and August 2009.

SRP will soon post a Business Practice for use of the SRP transmission rights on Eldorado System.

SRP advises potential transmission customers that all use of SRP transmission rights on the Eldorado System are subject to certain California Independent System Operator (CAISO) tariff charges and requirements, as follow:

1.) Charges: An SRP transmission customer using SRP transmission rights on the Eldorado System may be directly billed by the CAISO for certain CAISO tariff charges, including Grid Management Charges, Ancillary Services 1 and 2, and losses, among others. If any of the CAISO charges billed to the customer are duplicative of SRP regular tariff charges associated with use of SRP Point-to-Point transmission service, such as Ancillary Services 1 and 2, and losses, SRP will forebear from assessing such charges to SRP customers so that such customers are not charged twice for the same services. All CAISO charges that are unique to the CAISO, such as the Grid Management Charge, are the sole responsibility of the SRP customer, and SRP will not undertake any responsibility in any way for such charges, such as an involvement with invoicing or payment or disputes. Any regular SRP tariff charges that are not duplicative of CAISO charges, including applicable SRP charges set out in the SRP tariff schedules 7 and 8, will be assessed by SRP in accordance with its then current OASIS rates.

2.) Scheduling: An SRP transmission customer using SRP transmission rights on the Eldorado System must be a registered CAISO Scheduling Coordinator (SC) and conduct scheduling of such Eldorado System transmission rights in accordance with CAISO SC requirements. SRP takes no responsibility for any aspect of such scheduling.

3.) Electronic Tagging: Upon receipt of a Customer Confirmation of an SRP acceptance of a Transmission Service Request for purchase of SRP transmission rights on the Eldorado System, SRP will supply customer a “Contract Reference Number” (as provided by the CAISO) that such customer can use for electronic tagging of related transmission schedules with the CAISO. SRP takes no responsibility for any aspect of any such electronic tagging with the CAISO.

On June 2, 2009, the rating on the Mead-Perkins-Westwing 500kV Transmission Line was increased from 1300 MW to 1923 MW in both directions due to series capacitor upgrades and the permanent bypass of the Perkins phase shifters. All participants have increased their TTC in OASIS to reflect the rating change. SRP TTC has increased from 236MW to 349MW.

May 27, 2009

On June 2, 2009, the rating on the Mead-Perkins-Westwing 500kV Transmission Line will be increased from 1300 MW to 1923 MW in both directions. The rating increase is due to upgrades to the Mead-Perkins series capacitors as well as the permanent bypass of the Perkins phase shifters. Participants of this line will appropriately adjust their individual TTC values no later than June 1, 2009 to become effective on June 2, 2009.

SRP PROPOSES TO IMPLEMENT UNRESERVED USE BUSINESS PRACTICE

When its current OATT became effective on March 31, 2008, SRP specifically deferred implementation of unreserved use charges until a business procedure was developed. SRP is considering a business procedure based on those presently used by other western utilities. The resulting business practice is posted on the SRP OASIS homepage under the ‘Draft for Customer Review’ subfolder of the ‘Business Practices’ folder. SRP would initiate any such billing for unreserved use of the transmission system (overrun charges) concurrently with the effective date set by the SRP Board of Directors for a new OATT with modifications as proposed below.

SRP invites email comments on the draft business practice on unreserved use. Please send all email comments to: SRPT@srpnet.com. E-mail comments should contain the words “Business Practice Comment” in the subject line and must be received by May 22, 2009.

May 6, 2009

SRP PROPOSES TO MODIFY OATT

SRP is preparing modifications to the current SRP OATT to correct non-substantive typographic errors, clarify certain provisions and add new provisions consistent with industry changes and the FERC pro forma OATT. While SRP has not completed its review, the major changes identified to date include clarification of SRP Network Integrated Transmission Service facilities, elimination of language inconsistent with the provision of intra-hour reserving and scheduling of transmission service and modification of Attachment K: Transmission Planning Process, consistent with FERC and industry modifications.

A table of proposed changes and the red-lined SRP Comparability OATT showing the proposed changes is posted in the ‘Tariff’ folder on the SRP OASIS homepage.

SRP invites email comments on the proposed changes to the SRP OATT. Please send all email comments on the OATT to: Margaret.Rostker@srpnet.com. Email comments should contain the words “OATT Comments” in the subject line and must be received by May 22, 2009.

NEW POTENTIAL RESTRICTIONS ON ROLL OVER RIGHTS

Current and pending North America Electric Reliability Corporation Reliability Standards may require SRP to recalculate total transfer capability (TTC) and available transmission capability (ATC) for SRP transmission lines.  In the future, if and when SRP is obligated to change TTC and/or ATC values, SRP may also be required to restrict eligibility for rollover rights in transmission service agreements to ensure SRP retains sufficient transmission for service to SRP retail loads.    

SRP invites its transmission customers and other interested parties to provide comments and suggestions on this matter.  Please direct all comments to Mike Pfeister: 602-236-3970, Mike.Pfeister@srpnet.com

Comments are due by 12/25/2008
