During her remarks, Harris touted the so-called Puerto Rico Energy Resilience Fund, a $1 billion fund managed by the Department of Energy and designed by Democrats in 2022 to quickly address Puerto Rico's electrical grid vulnerabilities via the installation of tens of thousands of rooftop solar and battery storage systems across the island. That fund has taken a central role in the administration's plans to, as President Biden said in October 2022, "transform the entire" Puerto Rican grid.

While the Department of Energy declined to tell the Free Beacon how many solar panels have been installed using program funds, Sunnova Energy—one of two U.S. solar firms awarded funding to oversee implementation of the program—acknowledged that just "a small, initial batch" of installations have been completed across the entire island so far. The other firm, Generac Holdings, declined to comment.
