750 MW

Post by slick »

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?

I presume you mean MW - Megawatt? rather than mW

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

Interesting question Slick. First google response is 1MEGAWAT (just to be clear to pedants) powers 650 homes, so 750 x 650 = 487500 homes a year, which equates to 13,499 dead aunts

I did, thanks.

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.

Battersea power station was 500mw on a 15 acre site
22.5 acre site needed for 750mw, and it’s about an acre per pitch once you include the areas around it for the bag of oranges & magic sponge

No idea re cost, depends on whether it’s on a treadmill or not

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 viable

Thanks again.

I think the relocation thing has been done a few times before - going to lower income countries rather than building them from scratch, but you may well be right!

It seems reassembly might be a thing:
  • Tas Government flags partial sale of gas-fired Tamar Valley power station

    By Stephen Smiley
    Posted 4 December 2014

    The Tasmanian Government is looking to sell most of the Tamar Valley power station, which was forced on Hydro Tasmania. State-owned Hydro was forced to acquire the station at Bell Bay last year by the previous government.

    Energy Minister Matthew Groom has told a parliamentary hearing that Hydro paid $360 million for the asset that was only worth $200 million. ... Mr Groom said selling off the plant's main turbine - a combined cycle gas unit - was a serious option.

    "One of the potential options is the sale of the Tamar Valley power station combined cycle unit."

    It is understood a potential buyer could dismantle the turbine and reassemble it elsewhere.

    Hydro Tasmania and the Government have both stressed there are no plans to sell the plant's four open cycle units which would be retained to run during times of peak energy demand.

    https://www.abc.net.au/news/2014-12-04/ ... le/5940042
Although in this case I think they ended up recommissioning the plant in situ.

It actually can be commercially viable.
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.

Kogan Creek PS is 740MW, so close enough. It’s a single coal-fired unit.

Slick already confirmed it’s Megawats, which is normal parlance of measuring power station outputs. If ye going all pedantic on my lack of capitals , then I merely reposte that whatever X number of homes is, it will be X more than you own :P

Typical power densities of various types of power plants are:

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.

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.

But I guess in an alternative world, you would measure it in BTU per hour per hectare.

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.

I agree - though I wouldn't use "awful" so much as "overly complex" - even if there is a "naturalness" to many of the relationships.

I can't imagine doing complex calculations in imperial units, but I suppose not only did people do that, they did it manually, so I wonder if the fact that the relationships are generally based around numbers with a lot of divisors makes it easier than one would expect?

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
I did, thanks.

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.
Typical power densities of various types of power plants are:

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.
Am I the only person who loves the mixing of SI and imperial units in this way?
30 metres of 4 inch pipe okay for you luv?

Thanks. Put it over there with the 8' x 4' 18mm ply and 3.6m 2x4s.
