BajaNomad - CFE classification

CFE classification

elfbrewery - 4-23-2020 at 03:24 PM

I was reading about CFE rates, but I could not understand the 1A, 1B, ... classification. Is it by region or zoning? How do I know where I am in this (besides asking a neighbor)?
Thanks for your info.

Alm - 4-23-2020 at 03:36 PM

It's location letter. Baja has all 7 types from 1 through 1F.

current rates...

We are indeed tarifa 1 and it does show green on the map. Who knew!

pacificobob - 4-24-2020 at 06:46 AM

I have several questions about my CFE account. Why are some billed monthly, and others bimonthly?

pacificobob - 4-24-2020 at 07:23 AM

My bill shows GDMTH as the tarifa. Any ideas of what that means?

elfbrewery - 4-24-2020 at 10:49 AM

I just plunked in our location, Mulege, Baja California Sur, and it came back as GDMTH for the entire area of northern BCS. However, the dotted map shows that it should be more like 1A or 1B. Maybe I do need to ask someone nearby...

elfbrewery - 4-24-2020 at 11:58 AM

I don't have a bill. I was just trying to understand what the rates would be like in different areas of Baja or Mexico. Sorry....

why its clear as mud to me!

Maybe this is like (recently abolished) Mexican "Presunto Culpable" system - guilty until proven innocent? Tariff to be adjusted downwards later, if customer insists

. Good documentary, btw.

When we first had electrical services installed we were the first inthe area to get it. For reasons i don't remember, the transformer and pole were things i had to buy. If a fuse on the transformer blows, i have to pay to fix it. The guy who built the first casita and contracted to bring in the power made a series of decisions while i was absent regarding the cfe. I have little doubt his choices were driven by expedience rether than cost. We do use quite a few KWH for various pumps.

GDMTH is not about KWH of energy used over some period of time. Input from transformer to the only consumer must allow 100 KW draw. This is a big transformer, huge. Many transformers hanging on the poles are 25-30KW, this is enough for 4 or 6 average casas. Yours could power a couple of blocks

25KW transformer costs ~$US 1,500. Can't say about 100KW, not a common thing in my area.

When other people want to hook up, they share the cost of transformer with whoever bought it.

Yes. Baja.

What i need to do is find a way to get counseled on my options. Previous attempts to have it explained have been disappointing. When the plague eases up i should go to the la paz CFE world HQ, find someone to break it down for me.

How much did that pole and transformer cost?

Does that mean you personally own those things?

I'm really curious how that works if you get neighbors who want to hook up.

As far as I'm aware, if there are no poles and cables, or a transformer, close enough to your house to hook up to, you pay for those things yourself. If anyone else wants to hook up to that equipment, they have to share the cost of what you paid. However, that is only in effect for the first year. After one year, the equipment becomes CFE property, and others can hook into it without paying anything to the homeowner who originally paid for it. At that point, CFE is responsible for maintaining the equipment, so if a fuse blows, they have to fix it at their expense.
The exception to this is if the transformer is actually on your property. In that case, it remains private, and any neighbors who want to hook up to it could only do so wit your permission and by sharing in the cost.
Here is what happened in my area- it was a sparsely populated area, so I paid for one pole and cable, as well as paying something to the landowner who had had the transformer installed (not on his private property). Others who were in the process of building (the area is far more populated now) waited out the 1 year, so that they didn't have to pay the original landowner for the transformer, nor pay me a share for the pole and cables I paid for and which they then piggybacked off of.

What's your designation/classification (1,1A,1B...) now?

Alm - 4-27-2020 at 04:26 PM

There is also such thing as a camp - property with multiple tenants and existing power service to the camp. Everybody pays camp owner for the privilege to connect. Whoever buys the transformer, owns it. Those who join later, pay both the camp owner and the transformer owner. Cables and labor from transformer to casa everybody buys for himself, and poles too, if necessary.

pacificobob - 4-27-2020 at 04:29 PM

The way i remember it...the +/-100m of wire, pole,transformer, and 120 meters of underground conduit and wire was around $15k.
This happened in 2006, so the numbers could be wrong. Since then i have on 3 occasions had a fuse toast...always on my dime. When the nearby lots were developed i remember someone asking if they could tap into my transformer. I answered yes, for some sort of cost that was never mentioned. For reasons i don't know, CFE ran a different line to serve those lots. I need some knowledgeable council on options. Btw, thanks to all for contributing your thoughts.

elfbrewery - 4-27-2020 at 07:23 PM

Very interesting. I'm living in a place that could (but is going solar) go the camp route that Alm mentions. I bet the transformer would have to be one of bigguns. Thanks.

pacificobob - 4-28-2020 at 09:50 AM

That would work.

Alm - 4-28-2020 at 10:39 AM

GDMTH requires minimum 100KW draw, you can't draw 100 if transformer is smaller than 100. They determine KW by dividing your monthly consumption into months, days and hours.

CFE have price-list for aerial transformers, they don't even list anything over 75KVA there, must be too heavy to hang on the pole. Those mounted on the foundation can be bigger, but they shouldn't have installed anything even close to 100KVA on residential property without your consent. 5-10KVA is enough for most casas.

The consumer determines how much he needs when ordering CFE, and requests >100KVA or <100KVA service, accordingly. When your demand is below 100KW for 12 consecutive months, you may request to downgrade GDMTH to regular tariff even if your transformer is >100KVA.

Bajazly - 4-28-2020 at 11:17 AM

I'm installing a 150Kva on my property and according to CFE, my rate will be .67p per KWH across the board. Hope that actually come to pass.

pacificobob - 4-29-2020 at 07:34 AM

I forgot to mention my transformer is 25kva..
Alm, where could i petition to downgrade the
Gdmth? You are clearly knowledgeable on this stuff. Engineer?

Alm - 4-29-2020 at 11:10 AM

Pacificobob, this is what I saw on CFE website - you may request to downgrade after 12 months of low draw. I don't know the procedure, sorry.
