Solar Energy Possibilities Begin to Take Root in Puerto Rico

That could help raise the island’s renewable energy portfolio, which is currently only at 2 percent, and make it more resilient to future storms.The interest from private companies is already there. Solar companies like Sonnen and Sunrun are partnering with local nonprofits to provide battery and solar supplies. Tesla has been among the most ambitious with its efforts: in late September, Bloomberg reported the company was shipping hundreds of Powerwalls―its home batteries that can store energy from rooftop solar―to the island. Musk has been in talks with Gov. Ricardo Rossello to scale up the effort by sending Powerpacks―giant battery packages equal to 16 Powerwall batteries―to bring hospitals and city centers back online.That battery technology “could be used effectively to restore electricity to rural and isolated communities first, where they could provide electricity well ahead of when grid rebuilding efforts are likely to reach those communities,” said Clark Miller, associate director of the School for the Future of Innovation in Society at Arizona State University, which partners with the University of Puerto Rico’s National Institute of Energy and Sustainability.The new microgrids could work in tandem with the fossil fuel-powered centralized electricity grid, particularly in future storms like Maria, energy experts say.“These can provide individual pockets of power that would be hugely supportive to emergency relief and communications, to light and power tools for rebuilding, for the cleaning and distribution of water next time,” said Roy Torbert, principal on the Islands Energy Program at the Rocky Mountain Institute.More: Puerto Rico’s Solar Future Takes Shape at Children’s Hospital, with Tesla Batterieslast_img
