The big problem that people seem to be having is understanding that "averages" mean nothing with electricity. It's all instantaneous. This was a demand-driven crisis, and nobody seems to be focusing on that. If you can't produce exactly the power that you need right now, then the system is going to trip offline. So you need excess capacity to keep that from happening. Wind and solar can't provide that, because if it happens at night when the wind is not blowing, or when windmills are frozen and seized up, as happened here, then they contribute virtually nothing to the solution at the exact moment you need it.
What needs to be done is to create more reserve capacity, together with the ability to turn it on in a hurry in times like these. A situation that requires a written request to, and approval from, FERC or EPA or whomever, is simply unacceptable. What Texas and ERCOT need are:
1) Much, much more battery capacity, to store excess power for times like this
2) More natural gas storage, instead of production simply being sent out of state
3) More wind and solar, with the understanding that they are not reliable for peak (or even base) loads, but can supplement whenever available
4) More natural gas and nuke, which are generally available for base load, and generally can be turned up to meet peaks
5) Probably not decommissioning any coal plants until the nuke/gas/renewable supply is adequate to provide sufficient cushion for events like this
6) Improvements to the transmission and distribution grid
7) Operating rules that allow judgmental spinning of generators of any sort in any location to meet needs like this one
What is not needed is connection to the national eastern or western grids. I am on Entergy, which is part of the Louisiana grid, not connected to ERCOT. I've been through two hurricanes where I wish I had been on ERCOT. I also wish I were on ERCOT so I could have Green Mountain (100% renewables) as a provider, although I am not sure whether Green Mountain can survive this spike. I can honestly say that this is the first time in 17 years that I was glad to be on Entergy instead of ERCOT.
I disagree with the bolded. Everyone can point to bad experiences with the energy utility, but most do their jobs well. But this cold snap proved to be one of those rare events where grid integration would have provided the reserve capacity Texas needed. Now, you mentioned building new plants, winterizing and keeping more production capacity in state, which would allow for ERCOT to maintain its independence. The question will the rate payers accept the increase cost? Would grid merger prove to be a cheaper option?
As I said, I am not on ERCOT. I'm on Entergy, which is part of the eastern national grid. Overall, looking back over 17 years, I'd much rather have been on ERCOT for the entirety of that time. I'd say this is the isolated experience for ERCOT, whereas there have been multiple failures of the national grid in that time frame. If ERCOT learns from this and makes the necessary changes, as I think they will, I don't see anything to be gained from joining the national grid. Given the nature of the problem, I'm not sure the national grid could have supplied very much help. Everybody around us was dealing from the same issues, so I'm not sure there was much slack anywhere in the system. And a lot of the distribution issues were internal, which a national grid interconnect would have done nothing about.
That's true, but there will be a price. I'm fine with the new units of nuclear power and converting all the coal plant to NATGAS in Georgia, but there is an associated rate hike that residents aren't thrilled about.
As far as experiences, I've only been up and down the east coast. But what I can say is that the U.S. need way more (non-renewable) generation along with major investments in burying transmission lines.
Absolutely agree. My only point is that I don't see where it really helps ERCOT, which has been relatively problem-free during hurricanes and other cold snaps, to hook it up to a national grid that has far more problems. The big problem in Texas is that the shift to wind has been accompanied by a reduction in firm and reserve capacity as fossil plants have been decommissioned. Bring some of them back, if we can, to add to the reserve capacity, add nuke capacity (that goes for everywhere, not just Texas), improve the transmission and distribution grid, add some battery storage and also some natural gas storage, weatherize everything, and we should be good to go.
All the arguing about wether gas or wind production declined the most overlooks the essential fact that this was primarily a demand issue, and when you get that big a demand spike, with that little reserve capacity, you need all hand on deck and wind was a no-show. Reserve capacity, transmission, and storage are the solutions.
