Case 3:07-cv-04936-CRB

Action Plan to Release Hunters Point and Potrero from their RMR Agreements

--

Document 42-2

An Action Plan acceptable to the ISO for release of the existing generation at Hunters Point and Potrero from RMR contracts involves successful completion of a total of 12 transmission projects by PG&E, four peaking power plants by the City, and the Mirant retrofit of Potrero 3 with emissions control technology for its temporary operation.

Filed 03/03/2008

The ISO does not control the dates of completion of these projects, nor does it control the permanent shutdown of the Hunters Point and Potrero generation.
