750 MW
Posted: Wed May 13, 2020 9:01 am
Can anyone explain in very simple terms what this looks like? For instance, how many homes a power station (gas fired) this size could supply etc?

Kind of depends where in the world you are as power consumption per home can vary a lot, but you would expect somewhere between 350,000 and 600,000 homes

So pretty chunky then?
I have some follow up questions if you, or anyone else, knows about these things....
What kind of size would that power station be? Say in terms of rugby pitches?
Any ideas of costs of decommissioning, moving (overseas) and putting back together again - appreciate this would be very, very rough.
Well, Didcot B is around 1400 MW and takes something like 15 rugby pitches; but the design of these things can and will vary a lot. I would be extremely surprised if decommisioning, shipping, and reassembly was commercially viableslick wrote:I did, thanks.Saint wrote:I presume you mean MW - Megawatt? rather than mW

My own company looked at the possibility of selling one of our CCGTs and some ground work was done looking at what was required to disassemble it and ship it.
Slick - footprint will depend on the type of plant. CCGT are nice and compact nowadays. If you googled one and looked it up on google maps you might be able to get a rough idea how big they are.
I looked at one in Dublin - two turbines with a combined capacity of approx 750MW - total area of the site (excluding car park) is approx 64,400 square metres.

Wtf? You even read the first few posts ?!Nolanator wrote:You won't be powering many homes with 750 mW.

Yeeb, fix your units, it hurts my head. 1 MW = 1,000,000,000 mW
mW is milliwatts. MW is megawatts. Important distinction.backrow wrote:Wtf? You even read the first few posts ?!Nolanator wrote:You won't be powering many homes with 750 mW.
Whatever X is, it will be in the hundreds of thousands of average 3 bed houses in the western world.

I swithered over that and chose right it seems!Nolanator wrote:Misuse of units triggers me.
I do appreciate Slick putting a space between the value and the unit, though. Proper order.

Gas CCGT: 80MW/acre
Nuclear: 30MW/acre
Coal: 10MW/acre
Wind/Solar: <1MW/acre
Obviously some generalizations in these numbers and modern H technology CCGT plants would be higher than the 80MW/acre
As for plant relocations, this makes some sense for stranded low operating hours gas turbine assets (we used to do quite a lot of these but this market has dried up due to the reduced price of new gas turbines), but the economics don't really work for coal, as it's difficult to relocate the boilers, fuel handling etc. There are too many variables to give a meaningful cost estimate.

16 stones and above means you are a unit

Uk is a hybrid of both units , and laugh at foreigners downing their puny 500ml’s

In the UK, spacecraft crash because we don't have enough money to put fuel in or because we make people pilots because they are thoroughly, bloody nice blokes and their father was Wing Commander Smyth-Smedley-Smyth.

I agree - though I wouldn't use "awful" so much as "overly complex" - even if there is a "naturalness" to many of the relationships.Nolanator wrote:Imperial measurements are often quite accessible and ready to relate to. Inches, feet. Presumably they came to be used because they were in convenient sizes.
Fractions of the units are hideous, though. 7/16" ply? Fück off. The relationships between one unit and the next one up if generally awful as well.
