Entergy Texas Inc. filed a rate case with state regulators that includes a plan to pass along to customers savings from federal corporate tax reform and invest in new infrastructure.

Under the Entergy Corp. subsidiary's proposal, base and rider rates would collect a total nonfuel retail amount of approximately $926 million per year, an increase of $16.7 million, or 1.84% on average across all customer classes, according to a filing with the Public Utility Commission of Texas.

A rider reflecting savings from the federal tax overhaul would return approximately $201.7 million of excess accumulated deferred income taxes over a period of two years, resulting in the average residential customer seeing a monthly increase of $2.36.

Without regard for any other changes that may occur during that period, after the first two years the proposed change in the nonfuel retail amount would be 12.92% or $117.5 million, which would be an 8.18% increase were included, according to the filing.

Additionally, Entergy Texas plans to invest nearly $2 billion over the next three years, including construction of the Montgomery County Power Station (MCPS), three new transmission projects, and the upgrading or replacement of outdated infrastructure with new technologies.

The application is based on a 12-month test year ending December 31, 2017. The company expects a final order by Nov. 16.
