SAN DIEGO (KGTV) — As California deals with its worst energy crisis in two decades and the threat of more rolling blackouts, a lot of people are wondering who -- or what -- is to blame.Energy experts say last weekend’s blackouts are raising new questions about the way the state manages its electrical grid. California is the only state in the west that uses an independent system operator, an entity known as Cal ISO.“This is really just a demonstration that the reliability of the grid is less reliable with [Cal ISO] than when we just had regular utilities,” said San Diego-based energy consultant Bill Powers.Cal ISO manages 80 percent of California’s power grid. It manages the flow of electricity for investor-owned utilities like an air traffic controller manages the flow of privately owned airplanes down a runway. City-owned utilities like the Los Angeles Department of Water and Power are not part of the Cal ISO system.Cal ISO, previously known as CAISO, was formed in 1998 after regulatory changes during the Clinton administration that were designed to make the energy market more competitive.Powers said the fundamental idea was simple: “instead of having these monopoly utilities controlling everything, let's open up the transmission systems.”But it didn’t take long for flaws in the system to emerge. In 2001, market manipulation from companies like Enron prompted dozens of rolling blackouts.In other states like Arizona, utilities are responsible for the electrical transmission within their service territory. Those utilities are able to rapidly respond if conditions prompt the need for additional power generation, Powers said.“[It’s] one-stop shopping. Here it’s two-stop shopping,” he said. “You've got another layer of fat in there. And if that layer of fat is playing the game a different way, simply making sure everyone is covered, then you have the potential to have a breakdown. And we're now experiencing a breakdown.”The most recent major breakdown was in 2011, when 1.4 million San Diegans suddenly found themselves in the dark.A federal investigation into the Great Blackout of 2011 cited “inadequate real-time situational awareness” -- basically bad grid management -- and faulted several entities, including Cal ISO.Edward Lopez, the executive director of the Utility Consumers’ Action Network, said last weekend’s rolling blackouts were another example of bad grid management.“This is an indication that, again, this statewide organization needs to be better prepared and ready to jump into action quicker,” he said.Cal ISO blames another state agency for the recent rolling blackouts, the California Public Utilities Commission, along with California’s evolving energy portfolio.About one-third of the energy California now generates in-state is from renewable sources like solar and wind. When clouds roll in and the winds subside, that can be a problem.“Lack of resources, the heat, those go into account,” Lopez said, “but on the other hand, this was not unpredictable.”Even though more Californians have been staying home due to the pandemic, last weekend’s conditions were not particularly remarkable, he said. With the impact of climate change, above normal temperatures are expected to become more common.One solution to California’s renewable energy problem, he said, is to invest in more energy storage.Cal ISO’s own data shows energy demand last weekend was lower than in previous peak years and there were reserves available, Powers said.“Why do we keep reserves if we’re not willing to use those reserves when conditions get tight?” Powers said.City-owned utilities like LADWP that are independent from Cal ISO did not experience rolling blackouts, one reason Powers thinks there’s a problem with California’s energy air traffic controller.“Maybe we need better rules. Maybe we need a different system,” he said. 3871

SAN DIEGO (KGTV) -- Authorities have identified one of the teens killed after he was believed to have mistakenly jumped from a bridge following a crash on a Carmel Valley freeway. According to the medical examiner, 18-year-old Ruben Ortiz Jr., died after jumping from the bridge on State Route 56 near Carmel Valley Road around 11 p.m. Tuesday. The other teen who died after jumping from the bridge was a 17-year-old male California Highway Patrol says was the driver of the vehicle. A family friend says the 17-year-old was Jesse Garcia. A gofundme page has been started for him here. Two teenage girls were also seriously injured. RELATED: 2 dead, 2 teen girls injured after jump from San Diego bridge following car crashAccording to the CHP, a Nissan Altima was traveling on the road when the car spun out for unknown reasons and crashed into a barrier. CHP says when the car came to a stop, it was facing oncoming traffic. Witnesses told CHP that six people got out of the car, running across the freeway lanes toward the right shoulder to avoid oncoming traffic. Four people from the group then jumped over the right shoulder, not realizing they were jumping off the bridge, CHP says. The four fell 50-75 feet from the structure, and CHP officials said two males died at the scene.A 14-year-old girl and 15-year-old girl were taken to Scripps La Jolla Hospital with injuries of unknown severity.The two others from the group, who reportedly fled the scene after the crash, were located by police late Tuesday night, according to CHP. One of the teenagers is 14-years-old while the other is 15. RELATED: Man falls from SR-125 after crashAccording to Escondido police, the vehicle involved in the crash was involved in two separate police chases on July 9. Police say the responded to a crash on Broadway and North Avenue. Although the Altima wasn't involved in that crash, officers reported that they saw people getting into the vehicle who may have been involved in the crash.When officers tried to pull the Altima over, the driver sped away. The second pursuit happened later in the day around 12:30 p.m., police say.Both chases were terminated after police determined speeds were too high. 2204

SAN DIEGO (KGTV) -- At least one person died in a Bay Park crash as rain soaked the roads in San Diego County Sunday morning. According to California Highway Patrol, the crash happened just before 6 a.m. Sunday on northbound Interstate 5 just before Clairemont Drive.

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.
