By Advice Letter 3740-E, filed October 12, 2010.

__________________________________________________________

SUMMARY

PG&E's Advice Letter 3740-E, proposing to permanently close its Humboldt Bay Power Plant (HBPP) Units 1, 2, MEPP3, and MEPP 4, is approved. Any issues that the Commission must address relating to ratemaking, decommissioning, or disposition of the plant and related assets shall be addressed by separate Commission orders.

BACKGROUND

By Advice Letter 3740-E, PG&E announces its intent to retire Humboldt Bay Power Plant ("HBPP") Units 1 and 2. PG&E also plans to shut down Mobile Emergency Power Plant (MEPP) Units 3 and 4 at HBPP.¹ The Advice Letter does not discuss the 65 megawatt (MW) nuclear unit at the same site, which is already in decommissioning status.

The retiring HBPP includes two fossil-fueled boiler steam turbine generator units of 50 MWs each (Units 1 and 2), and two simple cycle gas turbine generators of 15 MWs each (MEPPs 3 and 4), with a total capacity of 130 MWs. In D.06-11-048, the Commission previously approved the new Humboldt Bay Generating Station ("HBGS" or "replacement units"), which consists of ten diesel engine-powered units with a combined capacity of 165 MWs. PG&E will fuel the replacement units with natural gas as the primary fuel and diesel fuel (distillate) as a backup. HBGS became commercially operational as of September 30, 2010.

In General Order 167, the Commission adopted Operation Standards for Power Plants. Operation Standard 24 requires Generating Asset Owners (GAO's) covered by GO 167 to obtain an affirmative declaration from the Commission prior to closing a generating facility or making any long-term changes in operating status.² The GAO must also confirm with the Control Area Operator that a generation facility is no longer needed for reliability.

On June 2, 2010, PG&E sent a letter notifying Commission Executive Director Paul Clanon of PG&E's intent to permanently shut down all remaining units at HBPP in the third quarter of 2010. PG&E states that the HBPP closure coincides with the estimated commercial operation date of the new HBGS. PG&E's letter states that HBPP is no longer needed to meet demand in PG&E's service territory, as the HBGS replacement units will perform the same functions as the retiring HBPP.

In D. 06-11-048, Opinion Approving Results of Long-Term Request for Offers (PG&E's Long Term RFO), the Commission granted PG&E's unopposed request for a Certificate of Public Convenience and Necessity (CPCN), a power purchase agreement and a construction contract for the new HBGS facility, to replace the existing HBPP units, now at the end of their useful life³. In September 2008, the California Energy Commission (CEC) approved PG&E's Application and Certificate to construct and operate the new HBGS. ⁴

On October 12, 2010, PG&E filed Advice Letter 3740-E, which proposes to permanently shut down the retiring HBPP units. The Advice Letter affirms that PG&E's resource planning process has already factored in the closure of HBPP. PG&E also provided correspondence between the utility, the California Independent System Operator (CAISO) and the Federal Energy Regulatory Commission (FERC) regarding the retirement of HBPP. PG&E's June 18, 2010 letter to the CAISO proposes to transfer two agreements, the Interim Dual Fuel Agreement and the Interim Black Start Agreement, from the retiring HBPP to the new HBGS within a late September-early October timeframe. On July 29, 2010, PG&E filed the proposed Agreements with FERC. FERC accepted the revised agreements on September 9, 2010. The CAISO's October 1, 2010 Decision on Conditional Approval to Extend Existing RMR Contracts for 2011 extends the black start and duel fuel contracts to the replacement units, conditional upon the operational start of the replacement units, and the subsequent retirement of the existing units.

Finally, PG&E states that the Commission need not address any Section 851 issues to approve the HBPP closure, as PG&E retains ownership of the land, and the Commission will address the decommissioning and salvage value in other ratemaking proceedings.⁵

NOTICE

Notice of AL 3740-E was made by publication in the Commission's Daily Calendar. PG&E states that a copy of the Advice Letter was mailed and distributed in accordance with Section III-G of General Order 96-A. PG&E also served the advice letter to all parties in the G.O. 96-B advice letter service list.

PROTESTS

No protests were filed.

DISCUSSION

By this resolution we authorize PG&E to permanently close the HBPP. In so doing, we note that PG&E is a Generating Asset Owner (GAO) as defined in GO 167, and the filing of this advice letter by PG&E is appropriate in order to ensure compliance with Operation Standard 24, which requires Commission approval before a GAO makes a long term change in the status of HBPP.⁶ PG&E has provided the requisite notice to the Commission, and taken appropriate steps to consult with the California Independent System Operator (CAISO) regarding the need determination, as set forth in PG&E's Advice Letter and its June 2, 2010 letter to Executive Director Paul Clanon. PG&E's proposed closure of HBPP is also supported by the following actions:

In D. 06-11-048, the Commission granted PG&E's request for a CPCN, approved PG&E's PPA to construct the new HBGS, and acknowledged that "The facility will replace the existing power plant at Humboldt Bay, which is at the end of its useful life."⁷ The CEC's approval of the HBGS in September 2008 also affirmed that the new Humboldt Bay units were built to replace the old HBPP. ⁸

The new Humboldt Bay Plant began commercial operation September 30, 2010. PG&E confirms that it no longer relies on the retiring HBPP to meet resource planning needs in its service territory, as the new replacement plant will provide for the same approximate capacity, and therefore fulfills the same reliability functions as the retiring HBPP.

In addition, both the FERC⁹ and the CAISO¹⁰ have reviewed and approved PG&E's request to revise existing contract provisions applicable to HBPP concerning interim blackstart and dual fuel capabilities, such that these provisions would be applicable to HBGS once HBPP retires. Thus, the CAISO has been notified and consulted regarding PG&E's plans to close HBPP and open HBGS. Both CAISO and FERC have approved of the transfer of contract conditions to HBGS. Therefore, it is reasonable for the Commission to conclude that HBPP is no longer needed for reliability once the HBGS is operational.

In its advice letter, PG&E states that it does not contemplate a need for the Commission to address any asset disposition matters pursuant to Public Utilities Code Section (Section) 851. PG&E states that assets that remain useful will be redeployed by PG&E in other areas, and that any remaining assets that are no longer necessary or useful will be disposed of as salvage.

We agree that ratemaking matters associated with closure of HBPP, if any, shall be addressed by the Commission in other appropriate proceedings. By authorizing PG&E to close the HBPP we do not prejudge any ratemaking or decommissioning issues related to the plant. We also do not prejudge any issue associated with disposition of plant assets, including matters addressed pursuant to Section 851. Those issues will be addressed in separate Commission proceedings.

COMMENTS

Public Utilities Code section 311(g) (1) requires that draft resolutions be served on all parties and subject to at least 30 days public review and comment prior to a vote of the Commission. Section 311(g)(2) provides that this 30-day period may be reduced or waived upon the stipulation of all parties in the proceeding.

The 30-day comment period for the draft of this resolution was neither waived nor reduced. Accordingly, this draft resolution was mailed to parties for comments, and will be placed on the Commission's agenda on December 16, 2010.

FINDINGS AND CONCLUSIONS

1. Operation Standard 24 of GO 167 requires PG&E to seek Commission approval before retiring HBPP.

2. PG&E filed AL 3740-E on October 12, 2010, proposing to permanently shut down HBPP.

3. In D.06-11-048 Commission stated its approval of PG&E's CPCN for the new Humboldt Bay Power Plant. The Commission stated in granting approval of the CPCN for the replacement Humboldt Project, that the new plant will replace the existing HBPP, which is at the end of its useful life.

4. In CAISO's October 1, 2010 Decision on Conditional Approval to Extend Existing RMR Contracts for 2011, the CAISO extended the Interim Blackstart and Interim Dual Fuel capability contracts to HBPP and provided for the substitution of the soon-to-be retired HBPP units with the new replacement Humboldt Bay Generating Station in those agreements.

5. FERC approved PG&E's requests to revise its Interim Dual Fuel Agreement and Interim Black Start Agreement with the CAISO to account for the replacement of the old HBPP with the new replacement Humboldt Bay Generating units.

6. PG&E sought and obtained CAISO and FERC approval to modify its CAISO dual-fuel and blackstart contracts, to provide for the substitution of the retiring HBPP with the new replacement Humboldt Bay units.

7. With the completion and commercial operation of the new replacement Humboldt Bay Power Plant, and the agreement of the CAISO, it is reasonable for the Commission to conclude that HBPP is no longer needed for reliability purposes.

8. Any issues related to the shut-down of the HPPP site involving plant and related asset disposition, including matters that the Commission must address pursuant to Section 851, should be considered in separate Commission proceedings.

9. Issues related to ratemaking and decommissioning of the HPPP should be addressed by the Commission in separate orders in other appropriate proceedings.

THEREFORE IT IS ORDERED THAT:

1. PG&E is authorized to permanently close the Humboldt Bay Power Plant (HBPP).

2. This Resolution does not resolve any issues related to the shut-down of the HBPP site that involve plant and related asset disposition, including matters that the Commission must address pursuant to Section 851. Those issues shall be addressed in separate Commission orders.

3. This Resolution does not resolve any issues related to ratemaking and decommissioning of the HBPP. Those issues shall be addressed by the Commission in separate orders in the appropriate proceedings.

This Resolution is effective today.

I certify that the foregoing resolution was duly introduced, passed and adopted at a conference of the Public Utilities Commission of the State of California held on December 16, 2010, the following Commissioners voting favorably thereon:

¹ PG&E's June 2, 2010 letter to the Executive Director.

² Operating Standard 24 reads as follows: OS 24 - Approval of changes in Long-Term Status of a Unit. The GAO maintains a unit in readiness for service in conformance with Standard 22 unless the Commission, after consultation with the Control Area Operator, affirmatively declares that a generation facility is unneeded during a specified period of time. This standard is applicable only to the extent that the regulatory body with relevant ratemaking authority has instituted a mechanism to compensate the GAO for readiness services provided.
