⚡ Keep the Town Powered
A growing town needs electricity. Build power near the houses to light them up: a lit home pays you for its power every second — a home in the dark pays nothing. Keeping the lights on as the town spreads is how you earn and afford to grow.
🔨 Build Power Sources
By default your cursor just explores — hover a house, plant, or line to inspect it. To build, pick a power source: press its number key 1–5 or click it in the build guide on the right, then click a tile near homes to place it (each source only powers houses in range — the green lines). You can build on open ground only — water, houses, and roads are blocked. Press Esc or right-click to stop building and go back to exploring.
📊 Watch the Dashboard
The bottom strip is your control room. Keep your colored supply above the white demand line — any red gap means homes go dark. The forecast shows solar fading into the evening peak — and wind sags then too — so plan ahead with batteries or gas. And demand keeps rising as the town grows and homes electrify, so a grid that's enough today won't be enough next week — keep expanding.
🏭 Two Ways to Lose
Pollution: gas is cheap and runs anytime, but it pollutes — lean on it too hard and emissions hit the cap → game over. Bankruptcy: every plant costs upkeep for as long as it stands, so an overbuilt grid bleeds cash even when idle — let your balance sit in the red and it's over too. Grow fast, but don't choke the town or overbuild.
🏆 How to Win: Sustainable City

- 50 homes powered (fewer on Relaxed)
- grid kept ~fully supplied — no brownouts
- no gas burning — sun, wind, nuclear & batteries only
