Land constraints are the main driver for this growing market. China may not be short of land overall, but near cities, which require the most electricity, there is a shortage of suitable space for solar installations. A solar plant needs roughly 2 hectares (5 acres) of land to generate a megawatt of power, so generating substantial power requires a lot of space. And China is the world’s biggest farmer of fish, according to the Food and Agriculture Organization of the United Nations, with a lot of facilities located close to major cities.

To see where these fish farm power plants are, type “maps” in the command line of a Bloomberg terminal screen and hit . Click on Datasets and type “power” into the amber box. Tick the box next to pwr_plants Global Power Plants near the bottom of the search results and click the Open in Map button.
