Power in Dream City: Diesel vs Solar vs Coal Power Plants

Play free in your browser

Nothing in a new settlement moves until the lights come on. In Omebly Dream City, power is one of the first things you place, and it’s also one of the choices that follows you for the rest of the game. This Dream City power guide compares diesel generators, solar mini-grids and coal power plants, and helps you pick the right one at each stage.

New to the game? Start with the main Dream City guide. If you’ve already read our budget guide, this post goes deeper into the power side of your running costs.

Quick answer: Diesel generators are cheap to build but cost more to run and pollute. Solar mini-grids cost more to build but have very low upkeep and make no pollution. A coal power plant powers three times as many homes but pollutes strongly and is noisy, so keep it far from homes. Start with what you can afford, keep diesel away from homes because pollution drifts with the wind, and move towards solar once your city earns steadily. Check the power group in the Budget to see what you’re paying.

Your power options

Dream City gives you coal power plants, diesel generators and solar mini-grids, and all three are available from the start. For most of the game, your decision comes down to cost, upkeep and pollution.

	Diesel generator	Solar mini-grid	Power plant (coal)
Build cost	Cheaper	Higher	Highest
Running cost	Higher	Very low	High, but powers 3× as many homes
Pollution	Yes, drifts with the wind; also noisy	None	Yes, strong and wide, plus noise

The coal power plant is the third option. It costs about five times as much as a diesel generator to build and powers three times as many homes, but it pollutes more strongly over a wider area and is noisy.

A diesel generator powers about 100 homes. Per home powered, solar is by far the cheapest to run, and a coal plant is a little cheaper to run than diesel.

Diesel generators: fast and cheap to start

Diesel is the quick fix. When you’re in Career mode with only a little money, a diesel generator gets your first homes powered without emptying your account.

The catch

• It costs more to run. That higher running cost comes out of your budget every month, and it adds up as you build more.
• It pollutes and is noisy. Pollution drifts with the wind, so smoke from a generator can end up over your homes.

Diesel placement tips

1. Put it on the edge of town, not in the middle of a housing block.
2. Watch which way pollution drifts before building homes near it.
3. Leave space around it so you can replace it later without tearing up a street.
4. Treat it as temporary. Plan from day one to move away from it.

Solar mini-grids: pay once, save later

Solar costs more up front, which can hurt early in Career mode. In return, it has very low upkeep and makes no pollution at all.

When solar makes sense

• Your city earns steadily. Once the Budget shows a regular profit, the extra build cost is easier to absorb.
• You want clean air near homes. Solar can sit close to neighbourhoods without polluting them.
• You’re planning for the long run. Every month, its very low upkeep saves money compared with diesel.

Solar placement tips

1. Use leftover corners between roads and zones.
2. Place it near the homes it serves since there’s no pollution to worry about.
3. Keep a little room for more solar as the neighbourhood grows.

Power plants: compare before you switch

As your city grows, a power plant becomes worth a look. It’s available from the start, but its size and pollution suit a bigger town with space at the edge. Compare it with what you already run.

How to compare

1. Open the Budget and note what your power group costs each month.
2. Place the power plant far from homes, ideally on the edge of town. Its pollution spreads wider than a diesel generator’s, and it’s noisy.
3. Check the Budget again to see how your monthly costs changed.
4. Watch residents. They speak their mind, and their mood is a good early warning if something near them isn’t working.

A power plan for every stage

Here’s a practical way to think about power as you grow through Settlement, Hamlet (100), Village (500), Town (2,500), City (10,000) and Metropolis (50,000).

Settlement and Hamlet

Money is tight. Asha’s first card tells you to place power along with your first street, homes and water. Pick diesel if that’s all you can afford, solar if you can stretch. Either way, keep it at the edge of your first block.

Village

You should be earning by now. Start adding solar to new neighbourhoods instead of more diesel, and think about where your old generator could be replaced.

Town and beyond

Your city is bigger and wages rise as it grows, so running costs matter more than ever. Lean on low-upkeep options, consider a power plant at the far edge of town, and keep polluting buildings well away from homes.

Reading power costs in the Budget

The Budget is your best friend for power. Monthly costs are grouped by department, and power has its own group. It shows every kind of power building, how many you have and what they cost.

A quick power check

1. Open the Budget and find the power group.
2. Look for the most expensive line.
3. Tap it, and the camera flies to that building.
4. Ask yourself: could this be replaced with something cheaper to run?

Pollution and the wind

Pollution drifts with the wind, which makes placement a real decision. A diesel generator that looks fine on the edge of town may still send pollution over your homes if the wind carries it that way.

• Look before you zone. Watch where pollution goes before laying out new homes nearby.
• Use distance. The further a polluting building is from homes, the better.
• Switch when you can. Solar removes the problem entirely.

Common power mistakes

• Building diesel in the middle of a housing block
• Forgetting that diesel’s higher running cost repeats every month
• Never revisiting early generators once the city is earning
• Ignoring which way pollution drifts
• Not checking the Budget after adding new power

Your power checklist

• Power placed with your first homes
• Diesel kept on the edge of town
• Solar added once income is steady
• Power plant placed far from homes, if you use one
• Power group checked in the Budget regularly
