World’s Largest Floating Solar Plant Planned for Japan

AI Summary

Japan’s Kyocera Corporation has already leveraged the power of open water with shoreline solar installations like the fixed Kagoshima Nanatsujima plant, pictured above. The new project, however, will be built around 50,000 solar collection modules actually afloat on the Yakamura Dam reservoir.


The modules will cover a water surface area of around 180,000 square meters. Engineers estimate the plant will generate more than 15.6 megawatt hours (MWh) per year. That’s enough to power approximately 4,700 average households.

More numbers: According to the company’s projections, the floating power plant will gather enough solar power from the surface of the dam to offset about 7,800 tons of carbon dioxide emissions annually. The facility will also include an education center adjacent to the plant, to provide classes for local students on environmental issues

Power generation is moving faster than most forecasts predicted. The professionals who see it clearly aren’t guessing — they’re reading closer. They’re reading the right things.
