TVA is asking all residential, commercial and industrial customers to voluntarily reduce their use of electricity until Friday afternoon.
They report that all available generating resources are being used to meet the peak power demand and that conservation efforts will help avoid power interruptions.
"When it's below 20 degrees, each time the temperature drops one degree another 400 megawatts of electricity is needed," according to Tim Ponseti, vice president of TVA Transmission Operations and Power Supply. That's almost the output of a large hydroelectric dam, he said.
Today's peak power demand is expected to occur tonight when temperatures drop into single digits. Demand could exceed 31,000 megawatts. Another peak demand will occur Friday morning with peak loads around 33,000 megawatts. The peak demand during the earlier cold wave was just below 32,500 megawatts on Jan. 7th.
TVA suggests the following:
• Turning down the thermostat. Lowering the temperature just one degree can result in a savings of up to 3 percent.
• Postpone using electric appliances, such as dishwashers, dryers and cooking equipment.
• Turn off nonessential lights, appliances, electronics and other electrical equipment.
TVA is again operating under a "Conservative Operation Alert" which curtails maintenance activities that could disrupt power supplies, and a "Power Supply Alert" meaning an unexpected shutdown of a large generating or transmission facility could reduce TVA's power supply reserves.

I would turn my thermostat
I would turn my thermostat down if it wasn't turned off. I do have the luxury of living in the country and having a catalytic wood stove for our main heat, with propane for times when we can't tote wood.
Remember when TVA used to promote insulating and heating efficiency back when it served the people instead of the energy cartels.
Didn't I see a headline a few
Didn't I see a headline a few weeks ago saying TVA might be hurting financially because of reduced demand!? Which is it? Can't they handle increased demand? A few days like this shouldn't be that big a deal.
TVA Cuts
(in reply to Anonymous1)
I thought I saw the same thing. I seem to remember something about cutting jobs because of low demand (emphasis mine).
Take from that what you will, but, when you've already cut 700 jobs and are trying to cut more jobs, you won't have the workforce needed to cover an increased demand. (Not including the plants that have closed/being closed)
Sorry, I don't plan to give
Sorry, I don't plan to give up "cooking equipment" for the duration. Maybe I make up for it by setting my thermostat at 67 during the day and 64 at night every winter.
Thermostat settings
(in reply to Rachel)
I installed one of those programmable thermostats several years ago. The presets, for the heat, are set to 55 degs at night. While I like the cooler temps, I would not subject my parrots to that (even though they would adapt one is a special needs bird and I won't put added stress on her), so I have night temps at 60. Now I heat up the house from 6-8am up to 68, then from 8am-4pm, it's usually set at 65. Then warms up from 4-10 pm to 68 again. I'm not sure that I save a whole lot doing that, I wonder if I save more just having 2 settings (one for day one for night). Less stress on the system and energy usage by keeping day temps at one setting instead of heating up then cooling down then heating up again.
Seriously, I was sort of astonished to see cooking equipment on their list.
Yes, they are cutting staff
Yes, they are cutting staff because of a "lack of demand". The have also been bragging about cutting executive pay, all while the CEO makes exactly double his predecessor.
Heat Pump
My solution is to keep one little room toasty warm for me ant the ancient dog. There is a radiant under floor heat pad under the desk and that is a bonus.
If you peruse the tiny house blog you'll see examples of entire homes that are 120 sf. Having a warm room that size doesn't feel like a burden. I can heat up the kitchen pretty quickly with the stove if I need to do kitchen-y things.
That way the heat pump can take a rest. No way is it going to pump heat out of this frigid air anyway.
We have natural gas heat and
We have natural gas heat and it is keeping up. It doesn't even run continuously. Guess we have adequate insulation. I'm still not looking forward to the bill.
We also have a programmable thermostat but we've been manually overriding it to lower the temp.
Thankfully no busted pipes so far, knock on wood.
Don't know what we'd do if there was an extended power outage. We have a gas fireplace in the living room that would still work, but I've read they can actually draw heat out of the room. We have south-facing windows that can warm up the living room by a few degrees when we open the blinds in the afternoon, but it wouldn't be enough.
Guess we would head south and look for a hotel.
Not sure what they mean by "cooking equipment." I assumed they meant non-essential stuff like crock pots?
Cooking equipment
(in reply to R. Neal)
I don't know, Randy, if I'm using my crock pot it's because I'm preparing dinner during a busy day. I can't imagine it would draw that much energy. Along those lines, what about coffee pots that stay on for 2+ hours to keep the coffee warm? Toasters aren't on that long, either, when in use. Or, waffle irons. These are items that are on for a limited period of time (other than crock-pots). Or do people keep these items plugged in all the time?
Listing cooking equipment was just weird, IMHO.
Contest
Do I win the cold house contest? I just noticed frost on the INSIDE of the windows in my BR and back office. And they are double pane windows. Now I love the view back there but Brrrrr. In a few weeks the windows will start to get good afternoon sun and that will be a compensating factor.
The problem with central heat is it blows air in to the center from any outlying cold zones. My next heat system will be a mini-split in the center of the house and I will just open the doors to the rooms i want to heat.
I'm calling for a
I'm calling for a Congressional investigation into this artificially created energy shortage just before TVA starts aggressively making the public case for small nukes.
Answer
I called TVA public relations to ask about "cooking equipment" and spoke with Travis, who said that they indeed meant your stove/oven and suggested using a microwave instead because it uses a lot less power. I asked about crock pots, toaster ovens and the like, and he said they, too, would use less power.
He also noted that the advisory has been lifted for now, but they are preparing for another round next week. I asked him why they didn't do something about that because I'm tired of this cold weather. He laughed and said he wished they could, and that they are keeping their thermostats low in their building and his office is cold.
Anyway, here's a link to the latest status update...
Hmmm Interesting
(in reply to R. Neal)
Glad I have a gas range! I can cook to my hearts content should I so desire!
I only use other kitchen appliances when needed, except for the coffee pot (which is plugged in all the time since it has a clock and auto start), and the refrigerator.
When I lived in NYS, I had one of the smallest electric companies, with one of the highest rates in the nation (at the time). I was pretty well trained to not keeping things plugged in/running, or using things like the dishwasher late at night when energy rates were cheaper. And yes, that company gave you a magnet that had all their rates listed for the different times of day. Sure saved a lot to run the dishwasher after 11 pm at 3cents per kwh than at 7 pm at 11 cents per kwh (at that time). I'm talking nearly 25 years ago now. Always bugged me that KUB didn't give customers a clear run-down of their rates during different times of day, unless they only have one rate.
You would think that...
...a giant electric utility like TVA would have a grasp on a simple concept like oscillation in a control system, and how this relates to having a certain amount of resources on hand (labor and power capacity) to deal with peaks and troughs.
