Question: what can 1 gw power?
Answer: A gigawatt of power will provide enough energy for about 700,000 homes. Assumptions: A typical home uses about 11,000 kWh per year. A baseline 1 gigawatt power plant with an uptime of 88% (typical for coal plants) will provide 1 GW x 365 x 24 x 0.88 = 7,700 gWh of energy over the year.
