Tesla has completed a massive, 55,000-panel solar farm on the Hawaiian island of Kauai that will allow them to experiment with medium-term energy storage at a utility scale. Hooked up to the farm are 272 of the company’s lithium Powerpacks, which are capable of storing of combined 52 megawatt-hours of power.
The project is the largest of its kind installed by Tesla since its acquisition of panel installer SolarCity Corp. The Tesla facility is estimated to cut the Kauai’s diesel and petroleum consumption by about 1.6 million gallons per year. As a result, approximately 44% of the island’s energy will now come from renewable sources. The Powerpack system will also be the first solar operation to reliably supply power 24/7.
Elon Musk, Founder, Tesla has claimed that the entire United States could potentially be powered by another 160 or so of these plants.
