SAN DIEGO (KGTV) – Another heat wave in the forecast could leave Californians in the dark this weekend. San Diego Gas and Electric is preparing for a hot weekend as high temps are expected to cause more strain on the power grid.Energy officials are hoping to avoid a repeat of last month when rolling blackouts swept through the state for the first time in 11 years.The California Independent System Operator, or CAISO, was forced to order blackouts in response to high demand.“For the grid to operate, demand on the grid needs to be matched evenly with supply,” said Helen Gao with SDG&E.Ahead of the heat this weekend, SDG&E meteorologists are closely monitoring conditions.At this point, CAISO says they haven’t told SDG&E to prepare for rotating outages over the weekend. CAISO says it plans to issue a Flex Alert, which it says is a voluntary call for conservation.CAISO said the recent rotating outages were the result of a number of factors, including generation units being out of service, reduction of the amount of energy California was able to import from other states, and a sudden drop in wind energy.If CAISO issues a flex alert, the power company will activate their demand response programs. It encourages customers to cut back on energy use to reduce strain on the grid. Outages would only be ordered by CAISO as a last resort. On Tuesday, the State Water Resource Control Board took action to prevent more outages in the future. They’re now along four gas power plants to continue operations past 2020. They were set to stop production as California transitions to cleaner energy sources. The extended deadline is expected to ease the strain on current systems while new energy and storage resources are being built.If an outage is planned for a neighborhood, SDG&E says they try to give all customers a heads up before the lights go out.How these rolling outages workRolling outages are a method that CA ISO uses to take the load off of California's power grid. When the state says the grid is under too much stress, each utility in the state has a percentage of electricity that needs to be taken off of the grid to meet whatever wattage CA ISO is aiming for, according to SDG&E. That amount that a utility will be asked to cut during these rolling blackouts is approved with CA ISO regulators every year.SDG&E determines which neighborhoods will be impacted by creating a list of blocks. Each of those blocks accounts for about 25 megawatts of electricity. Once CA ISO tells SDG&E how much power it needs to cut, SDG&E goes down that list from the top, de-energizing blocks until it is told to stop.The next day, the company picks up where it left off on the list, so that the same neighborhoods aren't affected every night. Once SDG&E goes through its entire list, it starts at the top again.Outages can last up to an hour but can also be relatively quick. Saturday, the first block de-energized lasted for about 17 minutes, according to the company.What you can do to helpTo avoid rolling blackouts, officials say the best way is to take energy conservation seriously. Because these outages are issued by the state, conservation is needed by all Californians in these instances.Officials recommend setting the thermostat at 78 degrees, turning off unnecessary lights and electronics, and using appliances before 3 p.m. to help save power.During power shutoffs, SDG&E suggests customers turn off air conditioners, keep refrigerator and freezer doors closed, and reduce their water use due to the need for electricity to pump and process water. For electric vehicle owners, charging should be delayed if possible until after the emergency shutoffs, SDG&E said.SDG&E offers more safety tips to keep in mind during an outage here. 3805

SAN DIEGO (KGTV) — County health officials say 12 new flu-related deaths have been recorded in the last week, as cases also trend upward.The new influenza deaths included a 34-year-old East County woman with an underlying medical condition who died from influenza A, according to the County Health and Human Services Agency. This season, there have been 32 deaths in the county related to the flu, compared to 24 deaths at this time last season.The county says 2,292 local lab-confirmed cases were also reported last week. In comparison, only 487 confirmed cases were reported during the same week last year. This season's to-date total sits at 9,919 cases, passing the 9,655 cases reported all of last season.RELATED: Influenza B causing high number of pediatric flu deaths this season“The number of deaths and cases being reported are a sign that influenza is not easing up,” said Wilma Wooten, county public health officer. “Vaccination is the best defense we have against the flu. People who have not gotten immunized should do it now.”County medical experts recommend residents protect themselves against the virus by frequently washing their hands, cleaning commonly touched surfaces and avoiding contact with sick people.The flu vaccine is available at local doctors' offices, pharmacies, and public health centers. A list of locations offering flu shots can be found on the county's immunization website or by calling 211 for the county's health hotline.Local health officials and the CDC recommends everyone 6 months and older receive a vaccine, especially those at higher risk of complications from the flu such as pregnant women, people with chronic medical conditions, and locals 65 or older. 1712

SAN DIEGO (KGTV) -- County Supervisors Wednesday sent a letter to Governor Gavin Newsom asking him to take a second look at San Diego, potentially allowing shuttered businesses to reopen amid COVID-19. In the letter, Supervisors Kristin Gaspar, Jim Desmond, and Councilmember Chris Cate of the sixth district said Newsom’s “one-size-fits-all approach to closing entire business sectors is misguided as evidenced by the many sectors in San Diego forced to close their doors again despite not having contributed at all to the rise in our local cases.”Supervisors also pushed the governor to give more control to local leaders and health officials. RELATED: San Diego Mayor Kevin Faulconer, other local leaders take action to keep restaurants open“It is time to give local control of this public health emergency to the elected leaders and clinical team closest to the people so that we can begin community specific healing based on local data,” the letter reads.The letter was sent after San Diego was added to the state’s watch list, forcing some businesses to halt indoor operations.Following the new rules, Mayor Kevin Faulconer signed an emergency executive order making it easier for restaurants to operate outdoors.RELATED: San Diego to close some businesses as COVID-19 cases spikeThe Poway City Council also voted to provide picnic tables to local restaurants in an effort to help businesses move outside.Read the full letter below: 1446

SAN DIEGO (KGTV) — At least two teachers are on leave pending investigations at Southwest Middle School in Otay Mesa West. A spokesperson for Sweetwater Union High School District confirms the investigations, saying the teachers are not allowed on campus at the current time.10News uncovered the investigations when a viewer reported that his daughter had been interviewed in the case. He says an assistant principal questioned her about one teacher's behavior, including conduct that could be considered sexually inappropriate.The father, who asked 10News not to use his name, says he's upset that he was not notified by the school before his daughter was brought in for questioning. "I would have preferred my wife to be there, or I could have had the chance to say no, I don't want her interviewed because these are very serious, morbid conversations to have with 12-year-old girls," the father said.He says the only communication he has had from the school is a robocall voicemail the day after the questioning to notify him that it had occurred and suggesting he ask his student about the topics discussed.A district spokesperson says they are limited in what information can be released by privacy and personnel issues. 1233

SAN DIEGO (KGTV) - Commuters trying to avoid traffic along the 56 in Carmel Valley are using side streets, worrying people who live in the Pacific Highlands Ranch neighborhood."It's the worst between 7:30 and 8:30 in the morning," says longtime resident Randy M. She lives in the Portico West part of the development and says she sees cars going 50-60 miles an hour down her block every day."Sometimes, if I'm walking my dog, they'll almost run me over," she says. "So I have to be really careful."The traffic is coming from State Route 56. When that backs up, people will use Carmel Valley Road as an alternative. But that gets jammed as well, leading some drivers to turn into the neighborhood and use side streets and alleys.Making traffic worse, a half dozen schools are in the area (see map above) and all of them start between 8 and 8:40 am."It's a nightmare," says Naz Nahani, who drives her daughter to Pacific Trails Middle School every morning."When you reach this area, you're pretty much at a stand still," she says.The Carmel Valley Planning Board has held a pair of meetings about the issue. Chairman Frisco White says they're trying to find a solution."If the streets are private, we may look into blocking them from traffic during the morning," he says. They've also looked into placing no turn signs on Carmel Valley Road to discourage drivers from entering the neighborhood.Another option that White has heard would be to ask the school districts to further stagger the start times, so the traffic will be spread out over a longer period of the morning.White says the problem may get worse before it gets better, as hundreds of new apartments and homes are being built in the area.Nahani thinks the city should add more lanes to SR-56 and to Carmel Valley Road."We're planning to move closer to the school because of this," she says. 1864
