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) - As the country celebrates the 50th anniversary of the Apollo 11 moon landing, people in San Diego are looking back at how companies in this city helped NASA achieve the historic flight.You could argue that, if not for San Diego, the moon landing would never have gotten off the ground, or landed safely on the moon.Ryan Aeronautical Company built the lunar radar system that helped guide the lunar lander as it touched down on the moon's surface.General Dynamics built the Atlas Rockets that took some of the flights into outer-space."They didn't take them all the way up to the moon with the Atlas, but they helped set the stage to move forward to doing it," says San Diego Air and Space Museum Marketing Director David Neville.The museum has an Atlas Rocket on display at Gillespie Field, towering above the skyline. It also has the Apollo 9 capsule at Balboa Park.One of the docents at the museum worked on the antennaes that helped the capsules stay in constant contact with mission control."I can bring people over here and point to it and say that's what I did," says Ronald Pitcher, who volunteers at the museum and was an engineer working on the Mercury capusule, the Gemini and the Apollo spacecrafts. "It's a proud moment to be able to do that."Pitcher says he feels privileged to have played a small role in landing a man on the moon. He wishes the US had sent more people up."There's no question in my mind that we should go back," he says. "We should have done it when we had the technology and the poeple and experience and facilities in place."Saturday night, on the 50th anniversary of the landing, the Air and Space Museum will host a party to celebrate. They have family activities planned, including a special documentary screening.For more details on the party, click here. 1820

SAN DIEGO (KGTV) - Behind every mammogram Dr. Lisa Watanabe looks at is a woman waiting, and hoping, for good news. Dr. Watanbe is a radiologist, and the Chief Medical Officer for CureMetrix, an artificial intelligence (AI) technology company focused on early breast cancer detection.Their FDA-cleared software is able to learn, using millions of mammograms, to identify, mark, and score anomalies. "Cancers that were missed by a radiologist were detected by the machine, some of them weren't even small, sometimes they were just obscured by dense tissue," said Dr. Watanabe.She says the technology has found breast cancer up to five years earlier than it was found by the human radiologist. "It may detect features on mammograms the human eye can't detect," said Watanabe.The technology is already being used by doctors around the world and is also available to anyone with internet access.Women can pay 9 to get their own CureMetrix second opinion by uploading their mammogram to the online portal DocPanel.Dr. Watanabe says the software is not meant to replace humans but rather help them do their job better.San Diego resident Amanda Caniglia says the technology gave her peace of mind. "As a woman and going for my first mammogram and knowing the family history, there is a lot of anxiety going into it, you don't know what to expect," said Caniglia.While Caniglia's initial mammogram results came back normal, she wanted a second opinion because of her family history of cysts, tumors, and cancer. When the CureMetrix results also came back as normal, it was a huge relief. "it really lowered my anxiety and gave me peace of mind because I was able to know I'm good to go, I'm cancer-free."The technology is lowering the number of false positives and catching cancer earlier, giving more women the chance to find a cure in time. 1846

SAN DIEGO (KGTV) - Community leaders are reacting to this week's move by state lawmakers to let voters decide in November whether to reinstate affirmative action.“It’s been a long, hard road and now we can actually see some light at the end of the tunnel,” said San Diego NAACP President Francine Maxwell on Thursday afternoon. It follows Wednesday's news that California lawmakers approved a proposal to repeal the 25-year-old law that bans looking at race, sex, ethnicity, color or national origin in college admissions, contracting and public employment.“The NAACP San Diego branch is elated that it was a 30-10 vote. Two-thirds majority said that things have to change and we're headed to November,” she added.Assemblymember Shirley Weber (D-San Diego) authored the bill and asked for support on ACA 5, which lets voters decide whether to reinstate affirmative action by repealing Prop 209.“The ongoing pandemic as well as recent tragedies of police violence is forcing Californians to acknowledge the deep-seated inequality and far-reaching institutional failures that show that race and gender still matters,” she told her colleagues this week.“African Americans have been at the bottom for over 401 years. Affirmative action was an opportunity so they could open the door to walk into colleges, to [have] the opportunity of economics, to change the narrative of their family,” Maxwell told ABC10 News.Republican Assembly candidate June Cutter from San Diego opposes the return of affirmative action. Thursday, she told ABC10 News, “It is a band-aid put at the end of the problem rather than trying to find a solution to the disparity that I absolutely acknowledge exists and instead of trying to fix it at the starting line we're trying to fix it at the finish line and that's what I have a real problem with.”Cutter said she believes real change needs to happen earlier through the course of opportunities in K -12 education within under-served and under-privileged communities.Assemblymember Weber was unavailable for an interview on Thursday but her office sent ABC10 News the following statement.“The fate of Prop. 209 will now be in the hands of voters on November 3rd. While it was sold as a civil rights law when it passed in 1996, Proposition 209 has cost women- and minority-owned businesses .1 billion each year, perpetuated a wage gap wherein women make 80 cents on every dollar made by men, and allowed discriminatory hiring and contracting practices to continue unhindered. Far from being colorblind, the bill has set up barriers to women and minorities to share in the economic life of California. Proposition 209 has hindered public policy, thwarted opportunity and maintained economic disparity long enough. It’s time to give voters a chance to right this wrong.” 2796

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
