The Incheon Tidal Power Station is a proposed tidal barrage power station in Incheon Bay, just outside the capital city of South Korea. The barrage would have 44 turbines, each with a power rating of 30 megawatts. What would the installed capacity of the Incheon Power Station be if it is built?

Okay, so this proposed tidal barrage power station would convert the energy that’s in water that moves according to the tides into useful electrical energy. This conversion happens when water moves through turbines, causing them to rotate, leading to the production of electrical energy in generators.

We’re told that this proposed power station has 44 turbines. And each of them produces up to 30 million watts or 30 megawatts of power. So then there are 44 of these rotating turbines. And each turbine-and-generator system produces 30 million watts of power.

So if one turbine is capable of producing 30 million watts, this means the total installed capacity of the power station would be this amount of power multiplied by the number of turbines in the station. 44 multiplied by 30 million watts is equal to 1320 megawatts. If this power station is built, then this is the installed capacity of the station.
