I'm interested in the wind farms near Albuquerque and have contacted them for data. No response so far.

So far as the state is concerned, as I have already said the lion's share of the state resource are in the east and southEast parts of the state. I'm confident in saying that the wind resource in the SE is very similar to W. Texas. For now it is way under-developed due to a transmission bottle-neck. PNM says that wind is as developed as it can be for now, but they plan to build more transmission capacity by 2022 and then the wind resource will be developed further. Look at the ERCOT generation data I posted above. On-shore wind+PV is an outstanding combination for fly-over country, and I know that both NM and Texas have thought about complementing California PV in a regional alliance but that will take political will the current bozos in the federal government do not have.

PNM's infrastructure plans reflect their desire to utilize their fossil and nuclear assets either for as long as they can or until contracts expire. Neither are the cheapest for the consumer or the community even before externalized costs are considered, but are the most profitable for PNM.

Tres Amigas http://www.tresamigasllc.com/ was supposed to provide an interconnect for all three regional grids in 2016, but is running very late and has been downsized if not completely ended:

I can't find any news about it after 2017. IIRR they were originally claiming they could ultimately move 20GW.

The website says 750 MW planned in 2016 but they are now talking about a 200 MW pipe-let.

I don't think there is much doubt that large scale regional sharing is key to replacing fossils with clean energy.
Unfortunately, a forward thinking government is needed.

Of course. I keep telling you to look at your PNM bill and to read the PNM IRP.
You do neither, and instead spout BS and FUD.

I tell you to learn about your NM wind resource, and in reply you quote a single day from California -- itself a refutation of your earlier BS that wind+solar only cover 8 hours of energy use a day.

Reference NM wind data or STFU.
Reference West Texas wind data* or STFU
Reference the PNM IRP or STFU
Reference the PNM consumer bill or STFU

*Why ? Because Eastern NM and West Texas are linked. I leave it to you to understand the ways that it matters to your ignorant thread.

Do you know how I can pull the trend data off their closed scata system with out working there at the wind farm?
Because that's what I was using.
I already know know NM and pan handle of Texas are on the same power grid. Remember I have actually been formally educated on the power grid here. I know where it is, where it goes, it's weaknesses, what and how most of the substation are linked.

You linking weather reports to "prove me wrong" is cute. Looks like you are grabbing for anything to try to make your point, what ever that is supposed to be.
The wind for cast you linked for April 17 is a typical day for this part of newmexico, the wind starts off easy in the morning, builds most of the day then dies off in the evening. This is exactly what I have been saying the wind does. So thanks for providing me right.

According to AP NM struggles to produce 20% of electricity with renewables. Our utility announced they will be raising rates to add solar capacity.

I guess 1 in 4 people struggling to keep up with their electricity bill isn't enough.

We don't need tresamigas.
The existing high voltage lines were upgraded to handle all the wind power coming on line.
From what I heard upgrading the existing high voltage AC lines only cost tens of millions of dollars. And tresamigas wanted 200 million for the small version, over a billion for the full version? No thank.
The texas and south west grid don't really need to be linked. This part of the south west grid just needed to be able to get all its wind power further west.
There really isn't any point in doing TA without texas. Once texas builds a huge surplus of wind power they will want to sell that surplus electricity and then TA or something will TA like be built.
I'm actually glad tresamigas isn't being built because then we would be forced to buy wind power from the texas interconnect exchange.
At least we will be forced to build our own, which is the lesser of 2 evils to me.

No, but the wind resource data itself is available. Since you refuse to reference data to back up your drivel I posted ERCOT and NM wind data (in the NREL link) in an earlier post to show just how wrong your statements are.

I posted the weather link to give you an idea how to collect data but other sources are available.

Go ahead -- look at the 2017 ERCOT wind generation graph posted in this thread. What is the range of average hourly capacity factor through the night ?
When during the 24 hour cycle is the nadir ?

This is the graph. Do you understand it ?

I believe the strategy New Mexico is using to achieve their renewable mandate is to develop various ways to store renewable energy so it can be used when needed, not when available. You can get a glimpse at what they are doing in this website.

The proposed DCHV line was never about NM per se, but a proposal to link the wind resources in West Texas and Eastern NM with the
California market.

It will happen because it makes a LOT of sense, saves money, and allows the clean energy economy to blossom. We just have to get rid of the monkeys in the White House.

Sort of, but at a 1 - 4 hour time scale. Battery is too expensive by far to cover larger windows of variability. For that, regional sharing is key in addition to demand response.

It is interesting to note that overall, about half of residential energy use is in the home and half is for transport. Electric vehicles are central to high penetration of clean energy because they insert much needed demand flexibility.
