The Blue Lake Rancheria microgrid powers a number of buildings on the reservation and helped provide energy when California’s Pacific Gas and Electric shut off power during wildfires.
In the following story, disempowered people lacking reliable services not only took action to help themselves but were generous to more-privileged neighbors who suddenly learned what it’s like not to have services.
This is a story about two kinds of power.
Erik Neumann reports at National Public Radio (NPR), “California’s largest electric utility took the unprecedented step of shutting off power to millions of customers beginning last October. The decision was meant to prevent power equipment from sparking catastrophic wildfires.
“Now a renewable energy microgrid on a tiny California Native American reservation is proving to be one solution to this ongoing problem. The Blue Lake Rancheria is located just north of Eureka, Calif. On the 100-acre campus, just behind the casino and hotel, Jana Ganion opens a chain-link fence. …
“Inside, in an area half the size of a football field, are more than 1,500 solar panels, slanted toward the noonday sun. Ganion is the sustainability director with the Blue Lake Rancheria, which includes about 50 members.
[Ganion] helped build this solar microgrid as part of the tribe’s goal to develop climate-resilient infrastructure and to be ready for earthquakes and tsunamis. But then beginning in October, it became useful in a whole new way. …
“As one of the only gas stations in the county with power, the reservation provided diesel to United Indian Health Services to refrigerate their medications and to the Mad River Fish Hatchery to keep their fish alive. The local newspaper used a hotel conference room to put out the next day’s paper. Area residents stopped by to charge their cell phones.
“Ganion estimates that on that day more than 10,000 nearby residents came to the reservation for gas and supplies.
“County officials had been warned about the utility shutoffs, but they didn’t know they were happening until that day, says Ryan Derby, emergency services manager for Humboldt County, where Blue Lake Rancheria is located.
” ‘Our entire planning model for the last 18 months got thrown out the window,’ Derby says. … ‘Humboldt County prides itself on being resilient,’ Derby says, ‘But I think in light of these public safety power shutoffs we realized how dependent we really are on electricity.’
“The county focused on residents who relied on medical devices like respirators or oxygen tanks. At the Blue Lake Rancheria, Anita Huff was directing emergency services for people with critical medical needs.
” ‘We had eight people here who could not have lived without electricity,’ Huff says. ‘So, we saved eight lives.’ …
” ‘Microgrids are very complex. In some ways they’re kind of like snowflakes where no two of them are the same because it depends on where you are on the grid and what your facility is,’ says Dave Carter, the managing research engineer at the Schatz Energy Research Center and the lead technical engineer on the [Blue Lake] project.
“Microgrids keep the electricity flowing to customers even after disconnecting from the overall power grid. During an outage, the Blue Lake microgrid goes into ‘island mode’ and a large Tesla battery system stores extra power and balances the energy supply and demand.
“By comparison, Carter says, conventional solar arrays have to automatically shut down during outages for safety so they don’t electrocute powerline maintenance workers or people who could come in contact with a downed line.
“Microgrids do come at a price. The Blue Lake installation cost $6.3 million. Five million dollars came from a California Energy Commission grant, and the tribe helped raise the rest. …
“Carter’s lab at the Schatz Energy Research Center is looking for ways to lower the cost of microgrids. In spite of the upfront price, he says, communities should consider what it’s worth to stay in control during a natural disaster. …
“Jana Ganion, with the Blue Lake Rancheria, says with future electricity shutoffs, rural communities, and Native American reservations in particular, need to be especially resilient.
” ‘Many, many tribal nations are located at the end of the line in terms of the electricity grid,’ Ganion says. ‘They may have no power. They may have poor quality power. Microgrids are just a way to do an end-run around all of that.’ ”
