How do I build hydro plants?

[hecose]

I already have the civilization advance (Electronics), and I have already built the Hoover Dam, but when I try to build hydro plants in my cities I can't find the option to do so. Are there certain conditions before I can build a hydro plant? Must I have another city improvement in the city first? Or must my city be on a river square? I have a number of cities next to river squares, but exactly on a river square.

The Hoover Dam acts as a hydro plant in every city on every continent, so you have no need to build any, hence why it has disappeared from your build menu.

Let me make the superstitions on a nation, and I care not who makes its laws.

[hecose]

The ability to build hydro plants didn't appear at all, even before I have finished building the Hoover Dam. So, does it mean if I'm halfway building the Hoover Dam, the option to build hydro plants will already be removed?

So, if I don't have Hoover Dam, can I build a hydro plant in any of my cities? Does the city need to be next to a river? On a river? Or any other criteria?

If you have built the hoover dam, obviously you dont need to worry about building hydro plants, because they're already going to be there. But if you don't have it, or in the process of building it, I believe you have to have a factory in the cities before it can be added to your building options.

The civilopedia is a great resource for questions like this. It will answer all the technical stuff like this.

Have you ever thought about your soul and can it be saved?
Or perhaps you think that when you're dead you just stay in your grave.

I think hydro plants are like Uni's, they cant be built until something else has been built first. Uni's need library, sewer system needs aqueduct, blah blah blah.

Hydro plants probably need at least a factory before they can be built.

[Cunobelin Of Hippo]

Yes,you need a factory to build any form of power producer. I believe you need a river square in your city radius, as well.

Hydro plants can only be built after Power Plants

What the...?

Some stuff I've seen here is accurate. Some of it isn't.

This is what I know:
* Hydro plants can only be built when there is already a factory in the city.
* Hydro plants require a certain type of terrain to be in the vicinity. I believe that either rivers or mountains will work, but I am not certain. I am sure, however, that hydro plants are terrain-dependent.
* You may build hydro plants even if you already have a regular power plant or a nuclear plant. You may not build a hydro plant if you already have a solar plant (because solar power is superior to hydro-power in every way except initial building cost).
* If you already have the Hoover Dam, you may not build a hydro plant.
* If the Hoover Dam is not yet complete, you may still build hydro plants.

I hope this helps...

If you have Hoover Dam, you dont' need to build any type of power plant (hydro, power, nuclear, solar)

You can only build hydro plants in cities near rivers.

My advice: Don't build hydro plants. They are too expensive and hard to build in all your cities. However, DO build the Hoover Dam. You can build it anywhere. And because it replaces all power facilities with hydro power, you get a boost in production, a reduction in pollution, a big economic bonus (since you don't have to pay upkeep on power facilities), and a big savings of industry (since you don't have to waste time building several hydro plants). Later on pollution will occur in your cities despite the presence of hydro power. If so make sure you have a mass transit and/or a solar plant.

Well here's a question then - according to the Civliopaedia, the Hydro plant replaces all previous plants (eg Coal Plants). I have built the Hoover Dam, which has placed a Hydro plant in all my cities. However, those cities where I had a Coal plant still has them (as well as the Hydro plants) - should I sell the Coal plants? I'm presuming yes...

[oryx]

You should sell any power plants, nuclear plants, hydro plants if you have Hoover Dam. These add nothing to production but you still have to pay to maintain them. Solar plants are another matter because they eliminate pollution.

If you don't have Hoover Dam hydro plants can be built only in cities adjacent to a river or mountain.

[BigDog]

You don't want to sell hydro plants if you've built the Hoover Dam - that was the whole point of building it, to put hydro plants in all your cities...
Another thing I've thought of - does the collosseum make the temple obsolete (so you can sell it) and the cathedral make the collosseum obsolete? And the same with Police Station vs Courthouse?

Hoover Dam acts as a hydro plant in all your cities. It doesn' actually build one in each of your cities. So, if you have Hoover Dam and a Hydro Plant (or other type of plant) you can sell the plant to avoid paying the maintinance, but still get the production bonus becasue of Hoover Dam.

No to all. They are cumulative with each other. Michelangelo's Chapel would be another case of looking at selling the cities cathedrals though, since Mike's Chapel acts as a cathedral in each of your cities. Women's Suffrage does the same for Police Stations also.

Ah....after building the Hoover Dam, each of my cities now have a hydro plant in the list of city improvements, even those cities without a factory - doesn't this mean I have an actual Hydro plant in each city? (I could be wrong - I have been known to be, it was around July last year I think...)

[Duke of Marlbrough]

Are you saying that each city can then build a hydro plant, or that each city instantly has a hydro plant built for it? Either way, it shouldn't be the case. You could have a different version of the game also....

When Hoover Dam is built, all your cities act as if they have a Hydro Plant in them. Nothing more. They don't get a free one built in it or anything. Once you build Hoover Dam, you can't even select to build a hydro plant in individual cities.

Post a saved game if you can show something different, but, (assuming you are play MPG on the PC) that is what happens.

[oryx]

Another point about Hoover Dam is that it acts as if you have a hyrdo plant in all of your cities, even if a city could not normally build a hydro plant.

[duke o' york]

Once you have the Electronics advance, the cities you have factories in already will be allowed the hydro plant improvement only if they have a river. If you decide instead to build the Hoover Dam (very wise), then all of your factories will be upgraded to hydro plants regardless of the presence of rivers. So you will initially only get the option of a factory. Once constructed, you can have power plant, nuclear plant, hydro plant, manufacturing plant and solar plant. If you have built the Hoover Dam you will not have the option to build either the power plant or the hydro plant, but will still be allowed to make those considered to be further advanced.
Is this clear? :crazyeyes

[Goatman]

Are you all saying that when you build additional forms of power, the lesser ones become usless? Does this include the manufacturing plant, because it seems to increase the production dispite anything else.

[duke o' york]

Well that's the tactical choice you've got to make.

Your factory will improve the number of shields produced by your city. The power plant will further improve this figure but you will continue to suffer from pollution. The nuclear, hydro and solar plants all allow you added production and reduced pollution but the manufacturing plant will give you hugely improved production but still some pollution. If you need all the extra shields and have spare settlers to clean up then go ahead and build it, but if you are confident that your hydro plants will be able to cope with all your production needs and you have mass transit then you can kiss goodbye to having to clean up pollution, at least around this city. I can't stand pollution so I always go with the latter, but in a one city challenge then I'd probably go with the manufacturing plant if I thought it necessary as you've already got a spare settler to clean up when you need it to. Gotta grab those SS parts!

[Goatman]

That didn't quite answer my question, so I'll rephrase.
Does building additional forms of power (E.g power plant, then Hydro plant) do anything other than reduce pollution.
