PG&E offers new details on proposed power shutoff; small area of Lake County could be impacted starting Wednesday afternoon
LAKE COUNTY, Calif. – Pacific Gas and Electric on Monday evening offered additional details about a potential public safety power shutoff that could come midweek and impact a portion of Lake County.
PG&E is once again considering the measure due to a strong wind event the National Weather Service is forecasting will move into interior Northern California.
The company said it anticipates the shutoff could begin Wednesday afternoon and impact 209,000 customer accounts across 16 counties. That’s about a third of the customers whose power was cut earlier this month across 35 counties.
Unlike the last shutoff, which covered all of Lake County and 37,400 customer accounts, the one that’s proposed for this week is expected to impact approximately 1,895 customers in Cobb, Kelseyville, Loch Lomond, Middletown and Upper Lake, including 65 baseline customers, according to PG&E.
A detailed map of the shutoff area can be found here or viewed above.
In addition to Lake, the impacted counties and the number of customers are: Alpine, 200; Amador, 13,131; Butte, 23,452; Calaveras, 14,586; El Dorado, 39,786; Mendocino, 862; Napa, 9,623; Nevada, 37,098; Placer, 18,773; Plumas, 785; San Mateo, 6,462; Sierra, 1,160; Sonoma, 33,613; Sutter, 229; and Yuba, 7,474.
PG&E President and Chief Executive Officer Bill Johnson told reporters in a Monday evening briefing that the company hadn’t yet decided on whether or not it would cut the power. That decision, Johnson said, is expected on Wednesday.
If the company moves forward with another shutoff, company officials said they will make notifications eight to 12 hours ahead of cutting power.
In the case of the North Bay, power could be cut starting at 2 p.m. Wednesday in order for deenergization to be complete by 5 p.m., the time the wind event is forecast to peak, company officials said.
PG&E said it activated its San Francisco-based emergency operations center on Sunday evening to monitor the weather event.
The forecast is showing the potential for strong and dry offshore wind gusts that may exceed 55 miles per hour late Wednesday evening through Thursday afternoon for portions of the Sierra Foothills, and gusts of 35 to 45 miles per hour for some North Bay counties, with some localized areas expected to experience 55 mile per hour gusts.
The wind event this week is forecast to be much smaller than the one two weeks ago, in which PG&E said it has identified more than 100 instances of serious damage and hazard on its distribution and transmission lines .
On Monday afternoon, the company said it began a 48-hour advance notification to customers who may be impacted by a shutoff beginning late Wednesday evening.
Michael Lewis, senior vice president of PG&E Electric Operations, emphasized that shutoffs are a safety measure.
“The sole purpose of PSPS is to significantly reduce catastrophic wildfire risk to our customers and communities. We know that sustained winds above 45 mph are known to cause damage to the lower-voltage distribution system and winds above 50 mph are known to cause damage to higher-voltage transmission equipment,” Lewis said in a written statement released by the company.
Two weeks ago, PG&E’s Web site sustained traffic at approximately 250 times its previous peak load, company officials told the California Public Utilities Commission at a special Friday afternoon hearing in San Francisco.
As a result, PG&E said it has created a new Web site to take on higher traffic volumes. It will provide address lookup for affected customers, community resource center locations as they become available and other PSPS event-related information. Online services such as energy bill payment, will be unavailable until after power has been restored.
The company said it also has strengthened its contact call center to better handle phone calls, will open community resource centers in affected counties on Wednesday and is working to strengthen its coordination with government agencies, in particular counties, cities and tribal governments in its service area.
