A question about power plants...

[FredLC]

In my first game, i didn't know that you can't keep all the power plants of the game and achieve an amazing industrial bonus, so i lost lots of time and shields building and rebuilding replaced ones.

Now i know that we have to replace the old ones in order to get the new, more modern buildings.

However, i'm not entirely sure of the exact benefics of each one over each other, and how many exactly you can keep. Only one? Two?

Can you guys enlighten me in that matter?

Regards .

Only one power plant will actually be active in a city at a time. So if you have "older" ones, you should sell them off.

Coal, Hydro, and Solar all give a 50% bonus to production
Nuclear gives you a 150% bonus to production

Coal has massive pollution, and Nuclear reduces pollution (but can melt down).

Hydro requires a river in the city radius, while Solar comes very late and is very expensive. (But with the Hoover dam, you get the hydro in all cities irregarldess of a river)

Hoover dam is must build for me. That way I don't have to bother with building any of the other power plants, and the hydro plants you get in you cities are maintenance free.

Ditto

Hoover applies only to the cities on that continent (I think). So if you have multiple continents / islands you still have to build some power plants.

Well guys.... coal actually increases factory output by 100%. And nuclear will ONLY melt down if the city with it is in civil disorder. With the hoover dam, you get the effects of 50%+ factory output BUT you can build ANOTHER PLANT IN THAT CITY. So, theoretically, a city can have a 200% increase in factory output. With a manufacturing plant, that goes up to 250%!!!! Hoover Dam is one of the best wonders because of this. In a game I was playing.... my best city had production 250... tactical nuke in 1 turn!!!!!

Just checked the stats in the editor. And coal, hydro, and solar all have the same production bonus value of 2. Nuclear and the Iron Works have a value of 4 and the manufacturing plant a value of 2.

 

[benjdm]

Even though you can build another power plant with Hoover's hydro, the effects are not cumulative. Try a before and after with selling your other plant. If it is a nuclear plant then it does provide more than a hydro, though. But if it is a solar plant you won't see any change.

 

[FredLC]

Hmmm... that raises a new issue...

If i can sell my older plants for the money, it sounds like a pretty good deal and as a good way of raising up my cash, as i won't have to keep paying golds per turn for maintenance...

But, if my citie gets attacked and the newer plant is destroyed, i think that the old one will take over and keep the production, am i right?

So, is it worth to keep "two" plants, one as reserve, in case of an attack, or is it better to sell them and let the cash come?

I didn't know about these differences I guess it is because in CIV 2 there weren't any between them.
All I know is that Solar plant also reduces polution

 

[Catt]

Don't have access to the game and editor at this PC, so somone correct me if I'm wrong, but IIRC:

Coal, Hydro & Solar each boost factory production by 50%.
Nuclear boosts factory production by 100%.

Coal generates pollution.
Hydro, Solar & Nuclear do not generate pollution.
None of them reduce pollution.

[The game manual says that nuclear plants increase production 150% AND reduce pollution, but the manual is wrong]

Hoover gives the effects of a hydro plant in all cities (even those without water). With Hoover you can build other plants and the hydro symbol will still appear in your city display, but you only get the benefit of one plant.

The relative benefits / drawbacks seem to be:

Coal: Available early. Requires "coal" strategic resource. May be built in any city with coal in its strategic resource box. Adds pollution.

Hydro: Available several techs after coal becomes available. Non-polluting, but may be built only in cities with fresh water (rivers only?) within their city radii.

Solar: Available many techs later than hydros. Non-polluting and may be built in any city. No resources or build restrictions.

Nuclear: Available very late in the game. Requires "uranium" strategic resource. May be built in any city with both: (1) fresh water within its city radius; and (2) uranium in its strategic resource box. Non-polluting, but may melt down (50%?) if its city goes into civil disorder.

On nuclear meltdown: It's been a while since I've seen it, but IIRC, some city improvements are destroyed, half the population is killed, and the 8 tiles surrounding the city are polluted BUT, unlike a nuclear bomb, the terrain improvements in the 8 polluted tiles are not destroyed.

 

[Catt]

I played with the editor and also ran some meltdown tests yesterday (after my post above).

A couple of clarifications:

Hydro plants require a river, not just a source of fresh water, within their city radius (unless given free due to Hoover, in which case no water requirements whatsoever). Nuclear plants simply require fresh water (i.e., river or lake) within city radius.

Nuclear meltdown does not destroy city improvements (not even the nuclear plant) and does not harm troops or workers either in the city or in the surrounding tiles. The 8 tiles surrounding the city are polluted, but the underlyiung tile improvements and terrain are not destroyed / degraded (as occurs with a nuclear attack). Half the city's population is killed.

Jeepers, until Catt got here it sounded like everyone was guessing.

From wut others have explained in a previous thread, I thought having a hydro plant, and a solar plant is useless - its either one or the other. And there is no point in selling a hydro and buying a solar since they do the exact same thing. They are exactly the same except you need a river for a hydro plant and it comes a lot earlier than a solar. Nuclear plants are 100% bonus, and a Mfg. plant will stack on them all.

Can you build a Factory, Coal Plant, Hydro plant, Nuclear Plant, and a Mfg. Plant for like 300% bonus?

Sorry if I wasn't clear -- the other posters were certainly correct in that only one plant actually provides a bonus -- if a city already has a coal plant and it builds a hydro plant, the hydro plant does not add any production bonus (and the coal plant disappears). So, say you've decided to replace that polluting coal plant with a clean solar plant now that you have the technology to do so -- sell the coal plant just before the solar plant is produced -- you'll get a few gold for it, and it will simply disappear otherwise.

With respect to the types of power plants, the only differences between coal / hydro / solar are: (1) pollution; (2) resource or terrain requirements; and (3) prerequisite technologies -- as you move up the tech tree you can build power without strategic resources and then without specific terrain features. The nuclear plant is the only "step up" since it gives a 100% bonus versus the others' 50% bonus (but also brings the risk of meltdown and reverts to the "coal" model AND the "hydro" model of requiring a strategic resource and a terrain feature). Thus, moving up the tech tree:

Coal Plant: 50% bonus and requires strategic resource
Hydro Plant: 50% bonus and requires terrain feature
Solar Plant: 50% bonus
Nuclear Plant: 100% bonus and requires both strategic resource and terrain feature

The manufacturing plant is like a modern factory -- it stacks on top of factories -- no power plants required.

Saem with me guys. I alwayz uesd to melt down my nucleer plantz so my favorit supar heero woud appeer RADEOACTIV MAN!!!! I wsa liek "Hey yuo slummy slug!! you are a Lunix usar!"

I thought the city needs to be on a river, not just in the city radius

Okay so lets just get this straight for the record books:

The best you can EVER get in a city is: 1 Factory, 1 Coal/Hydro/Solar Plant, 1 Nuclear Plant & 1 Mfg Plant.

This being a total of 250% bonus resources, can I get a 'hell ya'?

EDIT: Dont forget about the Iron Works Small Wonder, I think thats another 100% bonus.

 

[Catt]

Nuclear plant replaces coal / hydro / solar. So back it down to 200% (300% with Iron Works).

Also, an offshore platform doesn't modify (through a %) base production, but it adds one shield production in each worked coastal, sea and/or ocean tile [I can't remember if it is each of coast, sea and ocean or only a subset]; these tiles normally do not produce shields.

 

[Pygzilla]

With 1.29 at least the coal plant doesn't dissapear when hydro appears. I built hoover and then had to go ta all my producing cities to sell the coal in order to reduce my pollution. It might be a bug because all my hydros came from hoover and I didn't build them. But selling it did not affect production as already stated.
