Net Revenue Utility Following is an analysis of the change in net revenue comparing 2015 to 2014.
## Table 1 ##
The retail electric price variance is primarily due to: ?
formula rate plan increases at Entergy Louisiana, as approved by the LPSC, effective December 2014 and January 2015; ?
an increase in energy efficiency rider revenue primarily due to increases in the energy efficiency rider at Entergy Arkansas, as approved by the APSC, effective July 2015 and July 2014, and new energy efficiency riders at Entergy Louisiana and Entergy Mississippi that began in the fourth quarter 2014.
Energy efficiency revenues are largely offset by costs included in other operation and maintenance expenses and have a minimal effect on net income; and ?
an annual net rate increase at Entergy Mississippi of $16 million, effective February 2015, as a result of the MPSC order in the June 2014 rate case.
See Note 2 to the financial statements for a discussion of rate and regulatory proceedings.
The volume/weather variance is primarily due to an increase of 1,402 GWh, or 1%, in billed electricity usage, including an increase in industrial usage and the effect of more favorable weather.
The increase in industrial sales was primarily due to expansion in the chemicals industry and the addition of new customers, partially offset by decreased demand primarily due to extended maintenance outages for existing chemicals customers.
The Louisiana business combination customer credits variance is due to a regulatory liability of $107 million recorded by Entergy in October 2015 as a result of the Entergy Gulf States Louisiana and Entergy Louisiana business combination.
Consistent with the terms of an agreement with the LPSC, electric customers of Entergy Louisiana will realize customer credits associated with the business combination; accordingly, in October 2015, Entergy recorded a regulatory liability of $107 million ($66 million net-of-tax).
See Note 2 to the financial statements for further discussion of the business combination and customer credits.
