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) — County health officials say with the summer months well underway, they've seen an uptick in the number of children that have needed to be rescued from private pools after nearly drowning.Officials say there have been 49 rescues in private pools, beaches, and bays from March through July, compared to 37 in the same period in 2019 and 33 in 2018. Nearly all of those rescued this year have needed to be taken to the hospital for treatment.Of those 49 that occurred this year, 28 were in pools and 14 were in the ocean, lakes, or bays. The rest did not report a specific body of water. Many public pools have been closed since March due to the pandemic."Parents and guardians must take the necessary precautions to keep these incidents from happening," said Wilma Wooten, county public health officer, said. "Children who swim in pools at home are at higher risk of drowning, especially as parents struggle to supervise their children while continuing to work at home through the summer months because of the novel coronavirus."The county says it's important to teach children to swim, never leave a child unsupervised in or near water, avoid alcohol if you're swimming, and learn CPR.At home, the county recommends installing a fence around the pool and hot tub, installing pool alarms, and keeping an eye on drains and pool toys that could be a tripping hazard. 1389

SAN DIEGO (KGTV) - Clothing retailer Forever 21 announced Tuesday it may close three stores in San Diego County as part of its Chapter 11 bankruptcy restructuring. The affected locations, which include Fashion Valley, University Towne Center, and Parkway Plaza in El Cajon, could be shut down "pending the outcome of continued conversations with landlords,” according to court documents. Attorneys also said the list of store closures could change pending restructuring efforts.Forever 21 has 800 stores worldwide and plans to close almost 200. "We do however expect a significant number of these stores will remain open and operate as usual, and we do not expect to exit any major markets in the US," the company said. The chain was founded in 1984 in a small Los Angeles store by South Korean immigrants Do Won Chang and his wife, Jin Sook. The chain expanded quickly in suburban malls, and catering to young girls and women with a mix of inexpensive basics. The company perfected the fast-fashion model, drawing in customers with its frequently updated mix of clothes than what was offered at department stores or single brands.CNN contributed to this story. 1169

SAN DIEGO (KGTV) - Concerns continue to grow amid reports that President Trump may allow border officials to ban US citizens suspected of having coronavirus from re-entering the country.Five years ago, Les and Marilyn Widd retired and made a big move, buying an oceanfront home in Rosarito, Mexico. That dream retirement has suddenly been marred by worries about COVID-19 and a possible presidential action. According to published reports, President Trump is weighing rules to allow border officials to temporarily block an American citizen or legal permanent resident from entering, if there is reason to believe the person has coronavirus."Absolutely upsetting, absolutely upsetting," said Les Widd, 70.Details about the possible plan are unknown, but Widd has heard enough."It's violating your constitutional rights to receive treatment in your own country," said Widd.Widd says if either of them were to develop symptoms, they would have few options. Their hospital in Rosarito isn't accepting COVID-19 patients."In Tijuana hospitals, they are absorbing everything from surrounding towns. They're at the limit. Difficult to get a bed there," said Widd.Both the Widds have go-to hospitals in San Diego where they've received past treatments. Both are covered under Medicare, and they say they have a right to use it, especially during a pandemic."We worked all of our lives and paid into it. We should be able to use our Medicare," said Widd.He also questions how effective a border ban would be."If push comes to shove, I will try any way possible to get over the border ... People will lie about their condition to get across the border," said Widd.Various estimates place the number of Americans living in Rosarito between 12,000 and 15,000 people. 1762
