How this ranking works
Prices are a full year at McKinney's usage shape, from the ERCOT load profile for the North Central weather zone: 13,800 kWh a year, peaking near 1,882 in August and dropping to about 741 in March. Ranking on the year instead of the advertised 1,000 kWh moves any plan whose price depends on where monthly usage lands. It moves them here: Simple Saver 3 wins at 1,000 kWh and is not the cheapest once a full McKinney year is priced.
"Effective rate" is the yearly total divided by the year's kWh. Your home isn't the state-average home, so enter your real usage and every plan re-ranks against your own bills.
These are residential plans. Business and commercial supply in McKinney is quoted per site rather than published as a rate, so none of it appears here and a residential rate is not what a business would pay.
