Joint Greenhouse Gas Allowance Auctions

On January 1, 2014, the California Cap-and-Trade Program and Québec Cap-and-Trade System officially linked, which enabled the mutual acceptance of compliance instruments issued by each jurisdiction, and the jurisdictions to hold joint auctions of GHG allowances.  As part of California’s Cap-and-Trade Program and the Québec Cap-and-Trade System, ARB and Québec’s Ministry of Sustainable Development, Environment and the Fight against Climate Change (MDDELCC) will hold joint GHG allowance auctions to allow market participants to acquire GHG allowances.  

Auction notices are posted to the jurisdiction webpages sixty (60) days prior to each auction, as called for in the California Cap-and-Trade Program Regulation (California Regulation) and the Government of Québec Regulation respecting a cap-and-trade system for greenhouse gas emission allowances (Québec Regulation).  The Auction Notice provides information about eligibility, auction format, and greenhouse gas (GHG) allowances to be auctioned.

Auction Guidance Documents 

Guidance for Allowance Consignment to Auction

The Cap-and-Trade Regulation provides that allowances are allocated annually to each eligible electrical distribution utility or natural gas supplier (consigning entity).  Each calendar year, a consigning entity must offer for sale at auction all allowances that have been placed in the Limited Use Holding Account (LUHA) that were issued from the budget year that corresponds to the current calendar year.  Additional information on allowance consignment requirements, consignment transfers in the Compliance Instrument Tracking System Service (CITSS), and auction consignment and participation is available.

Auction Forms

Auction Bid Advisor Form

Section 95914 of the Cap-and-Trade Regulation (Regulation) requires that any entity participating in an auction that has retained the services of a Cap-and-Trade Consultant or Advisor regarding auction bidding strategy must ensure the following:

  • The entity must ensure against the Consultant or Advisor transferring information to other auction participants or coordinating the bidding strategy among participants;

  • The entity will inform the Consultant or Advisor of the prohibition of sharing information to other auction participants and ensure the Consultant or Advisor has read and acknowledged the prohibition under penalty of perjury; and

  • The Consultant or Advisor must provide the Executive Officer the following information:

    • Names of the entities participating in the Cap-and-Trade Program that are being advised;

    • Description of advisory services being performed; and

    • Assurance under penalty of perjury that advisor is not transferring to or otherwise sharing information with other auction participants.

The Consultant or Advisor providing services related to bid strategy must submit this information on the Auction Bid Advisor Form to ARB at the address on the form no later than fifteen (15) days prior to the next quarterly auction at which the Consultant or Advisor’s services will be employed.

Auction Application Attestation Disclosure Form  

Section 95912(d)(4)(E) of the Cap-and-Trade Regulation requires that each auction application include an attestation disclosing the existence and status of any ongoing investigation or an investigation that has occurred within the last ten years with respect to any alleged violation of any rule, regulation, or law associated with any commodity, securities, environmental, or financial market for the entity participating in the auction, and all other entities with whom the entity has a corporate association, direct corporate association, or indirect corporate association pursuant to section 95833 that participate in a carbon, fuel, or electricity market.  Further, the attestation must be updated before each auction to reflect any change in the status of an investigation that has occurred since the most recent auction application attestation was submitted.  Please refer to the Auction Application Attestation Guidancepdf for additional information.

An auction applicant may use the Auction Application Attestation Disclosure Form (revised December 2014) to submit the required attestation disclosure and updates to previously submitted attestations by completing the form and submitting an original to ARB at the address on the back of this form at least 30 days prior to an auction in which it intends to participate.

Cap-and-Trade Utility Disclosure Form 

Section 95914(c)(1) of the Cap-and-Trade Regulation prohibits the disclosure of information related to an entity’s auction participation.  Section 95914(c)(2) provides a list of limited exceptions to the prohibition.  One of the exceptions allows disclosure by privately-owned utilities that are required to do so by a regulatory agency (section 95914(c)(2)(D)), and requires those utilities to report to the Executive Officer within 10 business days of making the disclosure.  Entities qualifying for the exception in section 95914(c)(2)(D) may complete this form and return it to the Executive Officer within 10 business days of making the disclosure to satisfy the reporting requirement.

Example Letter of Credit 

An example letter of credit format for California auction or reserve sale applicants is provided below and is meant a guide only for entities that intend to submit a letter of credit as their form of bid guarantee for an auction or reserve sale.  Auction or reserve sale applicants will need to work with their financial institutions to ensure all requirements are met, as described in Attachment A to the Auction or Reserve Sale Notice posted for each auction or reserve sale, prior to submitting any bid guarantee documents to the Financial Services Administrator.  ARB encourages entities to submit draft letter of credit bid guarantees to the Financial Services Administrator for review prior to the auction or reserve sale bid guarantee deadline.  All physical bid guarantee instruments must be received by the Financial Services Administrator in final form by the deadline date and time as listed in the Auction or Reserve Sale Schedule provided in the Auction or Reserve Sale Notice, or the entity's auction application will be rejected.
