Yes, I stand corrected....in the coldest climes, heat will often make the relative humidity even less, so humidifying might be required over de-humidifying. It would probably be best to regulate both temps and humidity to stay in a certain range....that's the best way of saying it. Ideally, nothing colder than about 2 deg C, as in a cold fridge, and nothing hotter than about 30 deg C. Even so, the relative humidity should remain within a range of between 45-65% ideally.
It should be noted, as I have taken pains to explain here and there previously, that temperature is not the real enemy over a wide range...it is the humidity that changes the dimensions of more critical elements. For Example, wood can expand along the grain by 5%, and that is enough to split it or buckle it. But it's what it does to close rail joints that is the problem. One-hundred feet (32 meters) of Code 100 nickel-silver track will lengthen by a whopping 5 mm (0.25") over a change of 30 deg Celsius. That's nothing if you have six joints free to slide that are nominally 1/31" wide. But if you have tight joints and the space between them shrinks along a 30 meter length by 5%......!!!!! And that is what a change in humidity will do...if it reduces substantially, if shrinks the wood linearly so much that rails running atop the wood will also be compressed.
How is it going with your Modesto (beard) module building?

Excellent work. Just goes to show that you don't need a layout to enjoy model railroading.

Power Plant Scene
A coal fired power plant with coal piles outside. Maybe a newer style turbine addition being added to one section. Across the river a newer nuclear plant under construction with all the attendant construction cranes and flatcar loads of transformers, etc. Plus bridges over the river, and spur tracks, etc.
I know this is a late response to a very old post, but I just read it and it reminded me of an old Revell kit that I had seen a while back on E-bay.
I was thinking it would be a great start for this kind of diorama.
...until I actually found one on e-bay again and saw the price of nearly $1900.00!!!!
but I did see one that sold on E-bay for $600.00.
(this one says its 1/16 scale, but that is obviously very very wrong (at that scale it would be as big as a house).
The other ad says its HO scale.)
...and Con Cor made an N Scale Three Mile Island kit.

If someone wanted to model a powerhouse, coal or nuclear, you could save space by locating the structure near a river or lake. That would eliminate needing to include a cooling tower or two.
Actually, a nuke, whether a BWR or a PWR, would be very easy to represent in a compressed format. All that would be needed would be a large warehouse type building about 150 scale feet in height and made to appear built from concrete, windows optional. Just use one end or side of the building at the far edge of the layout and a great deal of it could even be painted on a backdrop. Along with several smaller buildings of sheet metal and an office building with a guard house and a guard tower or two and an electrified, double chain link fence (wonder if a DCC unit has a code for that?) topped with razor wire surrounding the whole complex. Now you would have an excuse to have armed guards (m-16's) on the scene. Makes the occasional RR detective seem kind of meek.
Not all nukes use a dome for the containment building, although that is part of what gives them some of their mystique. Also would give a destination for a Schnabel car with a transformer, turbine or steam generator load.
Now all of this has gotten me to doing some serious thinking, especially if I model in N scale!
I was going to do it on a river so you could have some bridges as well...perhaps the old coal plant on one side of the river and the nuke on the other.

Just added another good photo of one of those liquid air/oxygen cars back on posting #25
