I'd like to take a few minutes to illustrate, using a real-life example with images, why it's extremely important to use your past 12 months of usage when you shop for electricity!  To do this topic justice requires a pretty lengthy article, so bear with me, please.
I'll compare the results you would get as a subscriber to today -August 10, 2017- for a typical apartment vs. a larger house.
First, I used GeekYourRate to simulate the monthly usage for a 700 square foot apartment in the Oncor transmission and distribution territory (Dallas/Fort Worth, Midland, Tyler, and Waco).
NOTE: The results are similar for those living in the slightly more expensive Centerpoint transmission and distribution territory (Houston, Galveston, Corpus Christi).
Entering your zip code into my website will automatically determine which of the two companies distributes your power.
Then, I did the same for a 3,000 square foot house. Of course, the monthly kWh (kilowatt-hour) usage came out much higher in all 12 months, for the house vs. the apartment.
I then shopped for electricity for the apartment and the house on GeekYourRate.com
The cheapest 12-month plan that came up for the apartment was an Infuse Energy plan (plan name removed) that averaged just 4.54 cents/kWh including all Oncor charges!  Yes, that's correct.  The average resident of Texas pays nearly three times this much!
The cheapest 12-month plan that came up for the 3,000 square foot house was a Discount Power plan (plan name removed) that averaged 6.24 cents/kWh including all Oncor charges.
But here's the important part, folks:
The exact same Infuse Energy plan that was 4.54 cents/kWh for the apartment, would be 9.82 cents/kWh for the house!  That's a rate more than twice as high for the house as for the apartment, for the same electric provider and plan!  Also, it shows up on GeekYourRate as the 105th cheapest plan for the house, while it's the 1st cheapest for the apartment. The annual cost with this plan for a house would be $732 more than the very cheapest plan for the house.
Likewise, the exact same Discount Power plan that was 6.24 cents/kWh for the house, would be 11.62 cents/kWh for the apartment.  That's a rate nearly twice as high for an apartment as the same plan would cost for the house.  Also, it shows up on GeekYourRate as the 111th cheapest plan for the apartment, with an estimated annual cost of $637 more than the 1st cheapest plan for the apartment.
The lesson here, is this:
The rate (cost/kWh) you end up paying per month under ANY electric plan is highly dependent on that month's usage!  Trying to pick the lowest cost plan for your home is nearly impossible using PowerToChoose.org, because the providers "game" the pricing structures to their advantage.  PowerToChoose is not capable of dealing with these rate structures, because it only displays your cost at one of three EXACT usage levels: 500 kWh, 1000 kWh, and 2000 kWh.  Nobody's home uses power every month at exactly those levels.
Powertochoose.org performs ZERO calculations, and therefore cannot sort by lowest cost to you.  You might say that Powertochoose lets you sort plans by a "range" of either 500, 1000, or 2000 kWh.  My house uses power in all three of those ranges, so that doesn't help.  It's likely that yours does also, in at least two of them.
GeekYourRate.com performs over 5,000 calculations every time you view the results for your home.  Calculations are done for every month of your usage, and for every one of the 350+ electric plans available to you.  Calculations are also done to find out what happens with a given plan if you go from, for example, 1,000 kWh to 1,001 kWh or more. This is where the credits or extra charges often come into play.
To do these calculations requires that 350+ unique formulas, representing each of the 350+ electric plans, be developed, stored, and most importantly -- updated daily, in GeekYourRate's database.  The daily updates are time consuming and are the reason we must charge for this service.  But your cost to find the lowest-priced plan for your home is only $9.95, total.  A single $9.95 charge to access the results, not a monthly charge like some other shopping sites.  That's just $9.95 to save you at least $100 per year, or even $1,000 - as some larger-use customers have saved.
Any electricity shopping service or website that does not charge a fee to use it, is either:
a) Performing ZERO calculations;
b) Getting "referral fees" from the providers you sign up with, and almost without exception, limiting your available plans to those that make them money, or;
c) Funded by a non-profit entity such as the State of Texas (like powertochoose.org) and unable to find you the true lowest-cost plan for your usage.
So, Embrace Your Inner Geek and save big bucks on your electricity!
Thank you very much for taking the time to read this.
