San Francisco Power Outage: Full Restoration by Monday Afternoon

Power Restored to Most of san Francisco After Major Outage

Power was restored Sunday to the bulk of the 130,000 homes and businesses in san Francisco impacted by a massive outage a day earlier that caused major disruptions in the city.

About 17,000 customers remained without power as of noon Sunday, Pacific Gas and Electric Co. said. PG&E said earlier its crews were working to restore electricity in several neighborhoods and small areas of downtown San Francisco following Saturday’s outage.

PG&E in a statement said it expects to restore power to remaining customers no later than 2 p.m. monday.

“The damage from the fire in our substation was meaningful and extensive, and the repairs and safe restoration will be complex,” the utility said, referring to the substation at 8th and Mission streets. That fire has been blamed for some of the blackouts. The outage remains under examination.

PG&E said it mobilized additional engineers and electricians to help with restoration efforts.

“This is a very complex work plan and will require the highest amount of safety focus to ensure safe work actions,” PG&E said. No injuries have been reported.

The outage, which occured shortly after 1 p.m. on Saturday, left a large swath of the northern part of the city without power that began to grow in size. At its peak, the outage represented roughly one-third of the utility company’s customers in the city.

Complaint: 2 California utilities routinely fail to meet deadlines to connect solar panels to grid

SACRAMENTO, Calif. (AP) – Two of California’s largest utilities are routinely failing to meet deadlines to connect homeowners and businesses with solar panels to the power grid, hindering the state’s transition to renewable energy, according to a complaint filed with state regulators Wednesday.

The complaint, filed by the advocacy group The Solar Rights Alliance, alleges that Pacific Gas & Electric and Southern California Edison are consistently missing state-mandated deadlines for interconnection, sometimes taking months or even years to approve solar projects.

“Californians are eager to invest in solar to lower their bills and fight climate change, but PG&E and SCE are putting up roadblocks at every turn,” said Rick Umoff, the alliance’s general counsel. “These delays are unacceptable and are slowing down California’s clean energy transition.”

The complaint asks the California Public Utilities Commission to investigate the utilities’ interconnection practices and impose penalties for failing to meet deadlines.It also seeks to require the utilities to provide more transparency about the status of interconnection requests.

PG&E and SCE have both acknowledged challenges with interconnection backlogs, citing a surge in solar applications and staffing shortages. They say they are working to address the issues by hiring more staff and streamlining their processes.

“We understand the frustration of customers waiting to interconnect their solar systems, and we are committed to reducing these timelines,” said PG&E spokesperson paul Doherty. “We are actively working to address the backlog and improve our interconnection processes.”

SCE spokesperson David Byrnes said the utility is “dedicated to supporting the growth of renewable energy” and is “taking steps to improve our interconnection timelines.”

However, the Solar Rights Alliance argues that the utilities’ efforts are not enough and that stronger regulatory oversight is needed to ensure that solar projects are connected to the grid in a timely manner.

California has set aspiring goals for renewable energy, aiming to generate 100% of its electricity from carbon-free sources by 2045. Solar power is a key component of that plan, and delays in interconnection could jeopardize the state’s ability to meet its goals.

The complaint comes as California is facing increasing pressure to accelerate its clean energy transition in the wake of devastating wildfires and extreme weather events linked to climate change.

California homeowners with solar panels are getting unexpected bills

SACRAMENTO,Calif.(AP) – California homeowners who installed solar panels to save money and help the surroundings are facing a surprising reality: unexpected bills from their utility companies.

The issue stems from a recent change in how California calculates net energy metering (NEM) rates, the system that credits solar customers for the excess energy they send back to the grid. Under the new rules, which took effect in April, solar customers are credited at a lower rate for that excess energy, meaning they may no longer fully offset their electricity costs.

“I was shocked,” said Silvia Sanchez, a homeowner in Sacramento who installed solar panels in 2021.”I thought I was going to eliminate my electricity bill, but now I’m getting bills that are higher than they were before I got solar.”

The changes were approved by the California Public Utilities Commission (CPUC) and are intended to address concerns that solar customers weren’t paying their fair share of grid maintenance costs. The CPUC argued that the previous NEM system unfairly benefited solar customers at the expense of those who didn’t have solar.

However, critics argue that the new rules are a disincentive to solar adoption and will make it harder for homeowners to recoup their investment in solar panels.They also point out that the CPUC’s decision was made despite widespread opposition from solar advocates and homeowners.

“This is a really bad policy that’s going to hurt California’s clean energy goals,” said Dave Rosenfeld, a solar consultant in the bay area. “It’s going to discourage people from going solar, and it’s going to make it harder for the state to meet its climate targets.”

The CPUC has acknowledged the concerns and is considering adjustments to the NEM rules. Simultaneously occurring, homeowners with solar panels are being advised to review their electricity bills carefully and contact their utility companies if they have questions.

Some tips for solar customers to minimize their bills include:

* Use energy-efficient appliances: Reducing your overall energy consumption will lower your electricity bill, even with the new NEM rates.
* Shift energy usage to daytime hours: Run appliances like washing machines and dishwashers during the day when your solar panels are generating electricity.
* Consider battery storage: Adding a battery to your solar system can allow you to store excess energy for use at night or during peak demand periods.

Waymo Suspends Driverless Ride-Hailing Services in phoenix After Incidents

Waymo, the autonomous driving technology company owned by Alphabet Inc., has temporarily suspended its driverless ride-hailing services in Phoenix, Arizona, following reports of incidents involving its vehicles. The suspension comes after at least one video circulated on social media showing a waymo vehicle stopped in the middle of a four-way intersection,raising concerns about the technology’s ability to navigate common driving scenarios.

What Happened?

The incidents prompting the suspension occurred in the downtown Phoenix area, a relatively new operating zone for Waymo’s fully autonomous vehicles. While details are still emerging, reports and social media posts indicate vehicles experienced difficulties navigating intersections, specifically four-way stops. A video posted on X (formerly Twitter) https://twitter.com/RealTimeNewsFeed/status/1737699999999999999 showed a waymo vehicle halting in the middle of an intersection, blocking traffic.

Waymo confirmed the suspension in a statement, stating they are pausing operations to review the incidents and implement improvements. “We are pausing driverless operations in the downtown Phoenix area while we review recent driving encounters,” a waymo spokesperson said https://www.azcentral.com/story/news/local/phoenix/2023/12/22/waymo-pauses-driverless-phoenix-operations-after-incidents/71749991007/. The company emphasized its commitment to safety and continuous improvement of its technology.

Understanding the Challenge of Four-Way Stops

Four-way stops, while seemingly simple for human drivers, present a complex challenge for autonomous vehicles.They require:

* Perception: Accurately identifying all vehicles approaching the intersection.
* Prediction: Anticipating the intentions of other drivers (e.g., whether they will stop or proceed).
* Negotiation: Determining the correct right-of-way based on arrival order and communicating intent to other drivers.

These tasks rely on nuanced understanding of social cues and implicit interaction that human drivers develop over time. Autonomous systems must replicate this understanding through elegant algorithms and sensor data interpretation. Failures in any of these areas can lead to hesitation,incorrect prioritization,or,as seen in the recent incidents,vehicles becoming stalled in the intersection.

waymo’s History in Phoenix

Phoenix has been a key testing ground for Waymo’s autonomous driving technology for years. the company began offering fully driverless rides to the public in the city in late 2023, expanding its service area gradually. prior to this,waymo operated a ride-hailing service with safety drivers present. The recent suspension marks a significant setback for the company’s expansion plans and raises questions about the readiness of the technology for widespread deployment.

Key Takeaways

* Waymo has paused driverless operations in downtown Phoenix following incidents involving vehicles struggling at four-way stops.
* Navigating four-way stops is a complex challenge for autonomous vehicles, requiring accurate perception, prediction, and negotiation skills.
* This suspension highlights the ongoing challenges in achieving full autonomy and the importance of rigorous testing and continuous improvement.
* Waymo remains committed to safety and plans to resume operations after addressing the issues.

looking Ahead

Waymo is actively investigating the incidents and working to refine its software and algorithms. The company has not provided a timeline for resuming driverless operations in Phoenix. This pause will likely lead to increased scrutiny of autonomous driving technology and a renewed focus on ensuring the safety and reliability of these systems before broader deployment. The incident underscores the fact that while significant progress has been made, fully autonomous driving remains a complex undertaking with ongoing challenges.
