Power Outage Intended to Prevent Wildfires Will Affect Millions of Californians Who Use PG&E
The outage will impact 800,000 customers in Northern and Central California, and could last through Tuesday of next week. Because a customer could mean a business or residence that includes multiple people, the total number of people affected could reach the millions. It is the largest preventative power shutoff in state history, according to The Associated Press.
To reduce wildfire risk during the forecasted severe wind event, PG&E will implement a Public Safety Power Shutoff (#PSPS) in parts of northern, central and coastal counties. PG&E expects to begin turning off power later tonight, just after midnight. https://t.co/xIT52NtRGE pic.twitter.com/OJduogm3yZ— PG&E (@PGE4Me) October 8, 2019
The outage is an attempt to prevent tree limbs from knocking against power lines and sparking a blaze as strong winds follow a dry period.
"We implement this public safety power shutoff as a last resort," vice president of PG&E's Community Wildfire Safety Program Sumeet Singh said in a statement reported by CNN.
The National Weather Service (NWS) has issued red flag warnings for the North Bay Mountains and Valleys, East Bay Hills and East Bay Valleys starting Wednesday morning, according to CNN. This means that warm weather, low humidity and strong wind combine to increase fire risk.
"This is a recipe for explosive fire growth, if a fire starts," NWS said, as CNN reported. "Have your go back ready."

PG&E's response to these conditions comes after it has been found responsible for 2018's Camp Fire, the deadliest and most destructive fire in the state's history. Even before that determination, PG&E filed for bankruptcy in January because it faced so many lawsuits for wildfire damages.
Survivors of the Camp Fire, which scorched the town of Paradise, were skeptical of PG&E's action now.
"I understand their concerns but in my opinion it's too little too late, we already had our town burned to the ground," Ben Humphries, who lost his Paradise home in the Camp Fire and now lives in Oroville, told The Associated Press.
Another Paradise survivor, Jennifer Siemens, who also now lives in Oroville, questioned whether the shutoff was really the best solution.
"What's wrong with the power lines that they have to do this so much?" she asked The Associated Press. "We don't want any more fires, obviously, but I feel like they are going a little overboard."
Ultimately, the question is whether PG&E is capable of safely delivering power as the climate crisis makes wildfires more likely, The San Francisco Chronicle said.
California Gov. Gavin Newsom said the utility had no choice in this instance, but also needed to upgrade in order to avoid situations like this in the future.
"No one is satisfied with this, no one is happy with this," he said, as The Associated Press reported.
The shutoff will impact 34 counties across the state and eight of nine counties in the Bay Area, according to The San Francisco Chronicle. Only San Francisco County itself will be spared.
So far, nearly 5,000 customers in Solano County have lost power, as have nearly 600 in Marin. The power outages will occur in stages north to south and were not supposed to impact the Bay Area until around noon Wednesday.

At one point, there was concern that the outages would close the Caldecott Tunnel on Highway 24 and the Devil's Slide tunnel on Highway 1 in San Mateo County, but generators were installed to keep them open, The San Francisco Chronicle reported.
The Bay Area Rapid Transit (BART) system said train service would not be impacted by the outages, though some station escalators could lose power, CNN reported.

Select stations reliant on portable generators may face escalator outages.
BART has power redundancies to continue running trains.
The news also sent Californians to the gas pump and the supermarket to stock up.
"We sold out of lanterns this morning. The shelf is completely empty," Howard Gibbs, the manager at an Ace Hardware in Lafayette, 20 miles east of San Francisco, told The Associated Press. "We've got just a few flashlights left, and we're down to our last couple of propane tanks, too."

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
