Greater wildfire risks prompt growth of electrical ‘microgrids’ to rely less on PG&E
In his standard blue jeans and unbuttoned flannel shirt, David Liebman could blend in with many of the young students walking to and from classes at Santa Rosa Junior College.
But Liebman, manager of energy and sustainability for the college district, has something bigger on his mind than class assignments and midterm projects.
Liebman, 27, is heading a $5 million electrical infrastructure project that addresses climate change and fundamentally will transform the way energy is distributed and used on campus.
Using the new solar arrays at the Santa Rosa campus, Liebman is coordinating the development of an electrical microgrid that could operate independently of PG&E during nearby wildfires, or when the escalating threats of fires in the age of climate change prompt the utility to temporarily turn off power.
“Unless we change the infrastructure that runs our society, we’re going to be in a lot of trouble because we won’t be able to adapt to the significant changes that are happening to both the environment and technology in general,” Liebman said.
Fueled by solar energy and equipped with battery storage and a complex control system, the SRJC project is a small part of a much larger movement environmental experts say could fundamentally flip the paradigm on energy usage here and across the country. Before, massive power plants were turned on to meet demand for electricity; now, microgrids could help do that with available renewable energy such as solar, wind and geothermal.
