California ISO's Electric Tariff Filing to Reflect Market Redesign and Technology Upgrade (MRTU)

The transmittal letter is intended to provide the Commission with an overview of the MRTU market design and the MRTU Tariff. The attached testimony also provides a more detailed discussion of the MRTU market design and the MRTU Tariff. The transmittal letter and testimony should not, however, be relied upon to detail each and every change that is proposed by the CAISO in the instant filing. The attached tariff sheets contain each of the proposed MRTU Tariff changes.
