About Power Grid
Power Grid puts children in charge of a town's electricity for a whole day. People need the most power in the evening, solar only works while the sun is up, wind comes and goes, hydro and nuclear are steady, and batteries store spare power for later. Gas and coal can turn on whenever they are needed, but they burn fuel and make carbon dioxide.
After building, Run the day draws every hour from midnight to midnight as a stacked bar chart against the town's need, with blackouts shown in red. One star means no blackouts within budget, two stars also meets the CO₂ goal, and three stars uses half the goal or less with money to spare.
Eight towns each teach something new: batteries in a sunny village, a windy island, a river town with a dam, a desert city with afternoon air conditioning, a cloudy valley, a big city, a dark winter town, and finally a city powered with zero CO₂. A robot checked every plan for every town.
Best for ages 9+
