The Hawaiian Island of Kauai plans to generate 70 percent of its power from renewable sources by 2030 and to completely wean itself from fossil-generated electricity by 2045.
Currently, Kauai burns millions of gallons of fossil fuels annually to produce energy at night. Until now.
In its biggest project yet, since the company acquired the solar cell giant SolarCity, Tesla just built a 13-megawatt solar power station on the island. The installation consists of 54,978 solar panels covering 44 acres (18 hectares).
The solar cells will charge a 52-megawatt hour Tesla Powerpack battery station storing the solar energy produced during the day and deliver it to the grid during the evening hours to reduce the amount of fossil fuels needed to meet energy demand.
For some background info, Kauai, is an island in the Central Pacific, part of the Hawaiian archipelago. It’s nicknamed “the Garden Isle” thanks to the tropical rain forest covering much of its surface.
The dramatic cliffs and pinnacles of its Na Pali Coast have served as a backdrop for major Hollywood films, while 10-mile-long Waimea Canyon and the Nounou Trails traversing the Sleeping Giant mountain ridge are hiking destinations.
52-megawatts hour storage?
I think the correct phrasing would be “storage of 52 Megawatt-hours”, or 52 MWh.
It was fantastic project and will be furue energy , could you share the cost of project since the storage cost still a problem . What’s the business model PPA or others model .
