Rick, your request motivated me to finally dig through CFE's very confusing rate pages. (http://www.cfe.gob.mx/casa/ConocerTarifa/Paginas/Conocetutarifa.aspx) I've been meaing to do this for a while. Thanks! Here's what I found: 1. These rate pages don't display correctly in Internet Exporer 8, so I tried Firefox 8. Still not right, but at least when I got to the page that was clipped off (requiring endless scrolling back and forth to read each line), I could right click inside the problem area and select "this frame" then "open frame in new tab" or "open frame in new window" (your choice.) Finally I could see all the text. 2. If you are a residence in our summer-temperature region you are in the "tarif 1B" rate category. As far as I can see, your rate isn't affected by how many phases you have (single-phase 120V, or two-phase 240V.) I guess your meter just converts it all to kilowatt-hours (kwh). 3. Watch out: all these rates are monthly, but our bills come bimonthly so the kwh consumption you see on the bill is for TWO months. 4. WINTER rate structure (for December 2011): a. For monthly consumption totalling less than 175 kwh: Your 1st 75 kwh costs 0.733 pesos/kwh (consumo basico). The rest of your consumption costs 0.888 pesos/kwh (consumo intermedio). b. For monthly consumption totalling more than 175 kwh: Your 1st 75 kwh costs 0.733 pesos/kwh(consumo basico). Your 2nd 75 kwh costs 1.229 pesos/kwh (consumo intermedio). The rest of your consumption costs 2.593 pesos/kwh(consumo excedente). 5. SUMMER rate structure (for July 2011): (Changed breakpoints are in bold.) a. For monthly consumption totalling less than 225 kwh: Your 1st 125 kwh costs 0.643 pesos/kwh (consumo basico). The rest of your consumption costs 0.744 pesos/kwh (consumo intermedio). b. For monthly consumption totalling more than 225 kwh: Your 1st 125 kwh costs 0.643 pesos/kwh(consumo basico). Your 2nd 75 kwh costs 0.965 pesos/kwh (consumo intermedio). The rest of your consumption costs 2.553 pesos/kwh(consumo excedente). c. I believe summer rates are in effect from May-Oct, but it might be a different 6-month period. Notice that the kwh costs go down in the summer for every tier except "excedente", which goes up a little. Also, most of the breakpoints go up. So our rates are lowered in two ways during the summer. I always thought the rates would go up in summer to reflect the higher production costs. Instead they must be trying to subsidize the rates even more then to keep most people's total bills from fluctuating too greatly throughout the year. 6. If you ever have any running 12-month period when your AVERAGE monthly consumption exceeds 400 kwh, then you will be placed into a whole new rate tarif called DAC (Domesticos de Alto Consumo). Is this the "nosebleed" rate you mentioned, Rick? I didn't research these rates since this breakpoint is about 3 times higher than my average useage. 7. Rate increases: a. CFE increases every rate by a small amount every month. For 2011, the 5 rates shown above gradually increased by about 3.1% to 3.9% for the year. During 2010, they went up 3.5%-4.4%. During 2009 it was 3.6%-4.6%. b. It doesn't look like the rate "breakpoints" (175kwh, 225kwh, 400kwh) changed since 2001, but I'm not absolutely sure of this. 8. For comparison, the basico rate is quite a bit lower than in Arizona where I come from, but if you use 200-300 kwh/month down here the total rate can go up somewhat higher than in AZ. But not 2X or anything like that. Hope this is clear enough. CFE sure doesn't make it simple!
