Rolling blackouts

[clemsonfor]

You figured out the "green" electric car thing. Also the energy used to create those huge battery packs that last 6-10 years have to be replaced again!

Id lov solar myself but did the math and to get enough capacity to power my home id need something like $115K worth of them!!!!!

It takes about $20K -25K to put up a 3000 watt solar system tied into the power grid (no battery backup) around here.

Yea, but just think of the savings. It would easily pay for itself in just a measly 30-40 years.:laughing:

There building 2 new reators (mabe just one, not sure) at plant vogul on the savannah river in augusta. They have been building the site for years. I beleive they are at the preliminary stages of permits or have just about got them not sure? But there will be a new nuke plant in "GA. Those residents will pay for it, but it will sell surplus power to SC, FL , and AL and maybe a few others as well.

The last nuke plant built must of been a generation ago. Power co. Entergy purchased several in the N.East for penny on the 10 dollars after the reactor problem in new york.
Now 2nd or 3rd largest owner of nuke plants in america.
it will be back in favor when the coal/oil/natural gas plants have shut down by the "green" people that don't know how there elec. is generated now.

I like Hydro power, build more lakes so we can fish, store more water and have overpriced lakeside realty!

Texas and ERCOT (Electricity Reliability Council of Texas) tries to maintain a ~12% reserve.

Plant maintenance was schedule well before the 20 year cold snap and had to be approved by ERCOT. Several plants were already down, then 3-4 more tripped off-line due to not being able to run in the cold. Believe it or not, the non-peak season is NOW.

There are 3 power plants being built within a stones throw from here. 2 coal, 1 nuke. Right now they are in the permitting process but they are proceeding. Plus there have been several natural gas fired plants built within the last decade. Probably too many actually, as it drives up the cost of natural gas but since NG burns MUCH cleaner they are way easier to get built.

My belief is that electric cars will have very little effect on the grid because most of them will charge at night while you are sleeping. They will probably be tied into smart chargers that can shut down due to demand, and there is even talk of back-feeding the grid with reserve power stored in the thousands of cars that will be plugged in.

In fact, if you think about it, electric cars will be a boon. Since there is already little demand at night most of the power plants have to cut back to a smaller rate. But if electric cars pick up the demand most of them could sell power that would otherwise not be needed. Electricity replaces gasoline. Sure, a person or two will plug in and charge at work during the day, but I assume that the vast majority will need to wait until they get home to charge. I would buy electric stocks if you believe that electric cars will be the future.

In the end, it was a minor inconvience. Yes, we had rolling blackouts for maybe a day or two. It is a once in a 15 year event here. Better to have this happen now than in June, July, or August. I'm proud to be a Texan and I'm glad we keep our grid separate.

I imagine this would create quite a few upset people who plug their car in to top in off to go to work and find 4-6 hours later that their battery was drained by the grid rather than being charged and they can't get to work.

Which is why I belive the Chevy Volt is going to be the standard electric propulsion system for the next 20 years until battery technology catches up with what we really need.

I think the biggest issue with batteries will be recyclability.

How about power generation plants? Anyone remember when the last one was built in this country?

There have been dozens of natural gas turbine generating plants built in the last decade.

Rolling blackouts??? Come on, get better excuse than that to increase power cost. Everyone knew winter was coming, and this would be a good time to pull maintenence on some of the generators. Excuse me, but I need a better excuse. Maintenence during the main usage part of the season? I doubt any of this was scheduled. We have gotton cold weather here, lot of snow and ice, but nothing to call for rolling blackouts. Just lack of maintenence and another excuse to increase power cost. Fact is Fact. People north of us are laughing about the little dusting and ice. What would we do if we lived there?

Winter is the off season for power usage. The massive AC necessary to make large areas of the US habitable use much more power.

Why? Should not be any different than any other metal/liquid battery.....no mercury either.

Some said this but id hate to go get in my car and it be dead cause they sucked my power on a cold night to use it. They mentioned this on NPR as well. Also around here the cold nights is when the power is used crazy, as were normally electric here in the south. The summer has a lower demand.

As far as the power company taking power from a charging battery,I guarantee, it wouldn't be long before someone would begin to market a device that would interrupt a reverse flow to keep from waking up to a run-down battery. It wouldn't be difficult to do.

Besides that, a battery supplies dc current, so I really doubt that the power company would be interested in converting dc into useable ac.
