I just got off the phone with Gexa and here is what they are quoting today for 77469 Zip:

Standard residential program:

• Cost/kWh = .0874
• Billing fee = $4.79
• Meter reading fee = $4.30
• Tax = 8.25%
• Cancellation fee = $15

CO Onepass program:

• Cost/kWh = .9450
• Billing fee = $4.79
• Tax = 8.25%
• No meter reading fee or cancellation fee

I am currently a TXU customer. My most recent bill, meter reading 8/10/04, was for 3246 kWh used with a net billing of $337.83. I ran the numbers against Gexa for both programs and came up with the following:

• Standard residential program = $316.95
• CO Onepass program = $337.24

Net results:

• Using the Gexa CO program rate would be a breakeven.
• Using the Gexa standard residential program would save $20.29 or 6.0%

My 2003 expense with TXU was $2,228.37. If I switched to the Gexa Residential program at a 6% savings then my savings would have been:

• $2,228.37 x 6% = $133.70

Cost of OPM's would be:

• $2,228.37 x 2 = 4456 opm's
• $133.70 / 4456 opm = $.03/opm

INMHO $.03 is too high a price for OPM so I will be switching to the Gexa Residential account for the convenience of using my credit card to pay and receive miles or points depending on which card I decide to use.

BTW, the "up to 15% savings" are calculated against the local "Affiliated Retail Electricity Provider" which in my case is CenterPoint (Reliant), not TXU as others have posted.
