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) - Anyone touched by Alzheimer's knows how painful the disease is. "It's affected my family. It's affected most families. It's such a prevalent disease. As people get older, it becomes quite likely this will become an issue," said Paul Aisen, director of USC's Alzheimer's Therapeutic Research Clinic (ACTC).Aisen's team began their research in San Diego many years ago and teamed up with USC about four years ago. He's spent over 30 years trying to solve Alzheimer's mysteries and is leading the upcoming clinical trial.Aisen says the large-scale study is the culmination of decades of work from scientists worldwide."Our focus lately has been trying to alter the disease, prevent it, or significantly slow its progression. How should we do that? We think attacking amyloid early is the most promising approach," said Aisen. Researchers believe sticky amyloid deposits, which form on the brain later in life, start the Alzheimer's process. Aging, genetics, and lifestyle factors can all contribute to amyloid build-up.The worldwide clinical trial aims to target amyloid. A drug called BAN2401 will be delivered intravenously, designed to bind to the sticky amyloid. The binding neutralizes beta amyloid and helps "tag" it, so the immune system can recognize it and clear it from the brain. A previous phase 2 study showed that BAN2401 removes brain amyloid and possibly slows cognitive decline.They're seeking participants over 50 who are not yet showing symptoms of Alzheimer's but do have elevated amounts of amyloid on their brain. Researchers can determine that through a PET scan or spinal tap. "We think that the most promising approach of all is to take a vigorous attack on amyloid while the brain is still functioning normally. And we can see amyloid in people many years before they develop the symptoms of Alzheimer's."Investigators hope that by treating a patient with BAN2401 very early in the disease, before symptoms occur, it will significantly slow disease progression. "If we're successful, it will have a huge impact on human health," said Aisen. There will be 100 sites worldwide for the study, including major cities like San Diego and Los Angeles. Study participants will receive treatment for four years, given either the drug or a placebo. Results are expected in seven years, Aisen says.

SAN DIEGO (KGTV) - Approximately 900,000 San Diegans who pay for sewer services may have had their rights violated.It’s part of what being alleged in a massive new class action lawsuit against the City of San Diego, its Public Utilities Department and the San Diego City Council.The suit calls it an “illegal financing scheme”. Attorneys who brought the suit claim the issue surrounds the city’s million smart water meter system and how it was paid for.  The lawsuit alleges the city knowingly used about million from the city's sewer fund instead of the city's water fund to help pay for that meter system.Subsequently, hundreds of thousands of San Diego sewer ratepayers were allegedly misinformed about what their money was being used for. Attorneys argue sewer ratepayers were quite possibly paying for a system that they did not necessarily benefit from- the smart water meter system. It’s still unknown whether there were any rate hikes directly tied to this.The suit claims the situation was an unconstitutional grab of million in funds.The San Diego City Attorney’s Office is reviewing the complaint and will respond through the court. 1183

SAN DIEGO (KGTV) -- As apprehensions rise to new levels, U.S. Customs and Border Protection says the U.S.-Mexico border has reached a breaking point.At the San Diego sector alone, the apprehension of unaccompanied minors rose by 80 percent from fiscal year 2018 to fiscal year 2019. Most of the minors made their way to the U.S. from Guatemala and Honduras. The number of families detained in San Diego saw the largest increase. RELATED: Nearly 300 families may have been separated before 'zero tolerance' took effect, admin saysDuring fiscal year 2018, 1,032 families were apprehended at San Diego’s border. That figure rose sharply to 8,217 so far in fiscal year 2019, an increase of nearly 700 percent. Most families also came from Guatemala and Honduras. The agency says it’s also facing more large groups. So far this fiscal year, CBP reports 70 large groups of 100 or more compared to just 13 large groups in 2018. Border Patrol Chief Brian Hastings said during Tuesday's news conference that they've seen about 2,400 fraudulent family claims from April last year to February, with some migrants falsely claiming they are under 18-years-old or saying they are family members when in reality, they are not. RELATED: Secondary border wall construction startsCBP Commissioner Kevin McAleenan released a statement following the release of the report saying in part, "We are currently facing a humanitarian and national security crisis along our southwest border."
