Snow Conn Power Outages

Yes I'm familiar with ConEd.

When our company (Not going to say on here you can probably guess) was trying to get approvals to build (or contract the build of) a very large wind farm in Oklahoma, one of the big challenges was getting power to the major city where the energy would be consumed via a large tie line. I don't remember the length but was in the meetings where the engineers expressed this as being one of the things they would have to figure out. Our company is predominately coal and the engineers said that with coal transporting that distance wouldn't be an issue. Don't remember the details of it but perhaps because of the MW out put of wind compared to coal was the difference. It turned out that they didn't get all states to approve the wind farm so it became a moot point. That farm was not built.

They are now building (or Invenergy is) the largest wind farm in North America 1.5MW. Our company has the largest transmission & Distribution network in North America. We are relatively newish to wind/solar but have been doing power for a minute.

Of course I would expect anyone who is working for a Wind/Solar energy company to be pro renewables and so am I to a point. But my concern is there is too much hype about renewables being the savior and people acting like we have the battery and other means of grid reliability figured out when we don't. If we did, you wouldn't see what happened in Texas and what happens in CAL.

Let's not try and paint a rosy picture that doesn't exist, at least not yet. We have battery technology deployed and I've heard it is not going great from the sites we have them in. Though that was three years ago and I realize things are changing rapidly.

Our main supplier of electricity here in MN land, Xcel Energy, AKA NSP, has been pushing to have the users pay for the extra cost of building transmission lines to private builders of some wind farms. I fail to understand why the users should pay to have transmission line set up so that the private company can sell their electricity for a profit without the expense of putting up the lines.

So far, the MN PUC has blocked this attempt, but I'm sure that in the future, it will happen.

It isn't unusual for an energy company to do what they call normal rate recovery on major capital expenses and infrastructure. I could see why it would bother a fellow if the wind farms were something that wasn't even wanted or needed by the consumer in the first place. It would bother me too.

Again, the hype of renewables saving the planet puts pressure on everyone to make things like that happen. Some people are bought in and will sign up for energy that is produced by renewable energy and will pay the extra $$. Others are like, just give me the cheapest utility rates I can get. Those are the people who hate the wind farm being forced down their throat and being forced to pay extra for it.

I'm not against alternative sources but this country under this so called leadership is cutting it's face to spite the nose.

We are not ready to go green. Pretty dam sad when we are having rolling black outs in this great country when the solution is right in front of us.

About the grid using batteries to store the electricity from wind/solar farms, as I understand it, it doesn't matter as to the battery technology, it's all stored as DC. (Actually chemical form which can convert to DC electricity.) The Grid itself is AC. Transformers work well with AC but not with DC. How are the batteries converted to AC (which has to be pure sine wave) in Mega watt quantities?

Big inverters. I've worked on multi MW electic motor drives. Similar thing

I guess I don't see the solution that is "right in front of us". If you mean coal, we tried coal for 100 years - but there was no way to clean up the air. If you are over 70, you remember the way that smog stank and lay as a pall over every city, in every valley, and sometimes whole sections of a state. In fact, it was efforts at smog control that started the whole "green" movement.... we talk about climate change a lot now, but that came into the green movement decades later.

The wasy we got into this divisive mess is one of those recent pieces of history that is so obvious to people who lived at the time that it keeps being overlooked.

As for batteries and storing energy, batteries are only one way to store energy. Not the only way, just the easiest - so its the first thing people think of. The solution is to store it some other say. The way to solve a problem is when something doesn't work; try something else.

We have scrubbers on all of our units now that have all but eliminated a lot of what you describe. But it doesn't matter. The media controls this country now and people will believe what they tell them to believe. Not a lot of folks on this site, but most other people. People do not do their own research or learning any more. Just believe the sound bit.

Listen to this, and send it to everyone you know to watch. This guy WAS an advocate for wind/solar.

If that video was allowed to be shown to High School and college aged kids, we would be living in a much different and much improved world.

Yes! I remember the smokestack "scrubber wars"! In the 70s and 80s I knew people involved with steel production and the scrubbers at Crucible Steel in Syracuse. Another friend ran those plants. That was the era when Crucible Steel was bought out by Colt Industries - a company notorious for taking a hard line on profit.

Crucible had installed modern scrubbers in the Syracuse plant but they didn't work to spec. And when they were scrubbing to spec, the cost of the energy inefficiency ate up the profits.

So everytime I visited, my friends were always in some angry battle with either gov't regulators, their Colt Ind. owners, or the local town people and local officials - all of whom had different ideas about scrubbing.

I got to watch from the sidelines because I didn't have a dog in that fight. And noticed two things:
1. Most of the time the scrubbers were "down" for one reason or another - but the steel production never was.
So the air quality didn't change much.
2. The whole subject of smokestack scrubbing changed from an engineering problem into a political divide that still existed 30 years later. I'm guessing it still does.
