On July 22, 2011, the PUC issued an interim D&O granting HECO a net increase of $38.2 million in annual revenues, or 2.2%, net of the revenues currently being recovered through the decoupling Revenue Adjustment Mechanism (RAM), effective July 26, 2011. Including the RAM revenues, the total annual interim increase is $53.2 million, or 3.1%. If the interim rate increase exceeds the amount of the increase ultimately approved in the final D&O, then the excess would be refunded to HECO’s customers, with interest.
