Texas 2017 Rate Case [Table Text Block]

The following table summarizes SPS’ rate increase request:

Revenue Request (Millions of Dollars)
Incremental revenue request	$	69
TCRF revenue conversion to base rates (a)	(14		)
Net revenue increase request	$	55

^(a)  The roll-in of the TCRF rider revenue into base rates will not have an impact on customer bills or revenue as these costs are already being recovered through the rider. SPS can request another TCRF rider after the conclusion of this rate case to recover transmission investments subsequent to June 30, 2017.
