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) - At the end of the week, many federal government employees may find themselves in a financial bind as they arrive at their first pay period of the shutdown without a paycheck. Enrique, a federal contractor who did not want to use his last name, created a GoFundMe campaign to cope with the lack of funds. He asked for ,000 to cover his salary gap, posting a picture of his family to encourage donations. “This shutdown really affects me because once the shutdown ends I will not get back pay as a contractor,” Enrique said. Christian Rodriquez is a corrections officer at Metropolitan Correctional Center detention facility in downtown San Diego. His work is deemed essential, so he is working without pay."I'm going to have to borrow from family and friends to pay my mortgage, or get a loan," said Rodriguez.Some institutions, including Navy Federal Credit Union (NFCU), are offering no-interest loans to help workers through the crisis. Other banks, including Chase and Wells Fargo, encouraged affected customers to reach out for assistance.While some loans may have fair terms, government employees are warned to beware of so-called predatory lenders during the shutdown. The California Department of Business Oversight (CDBO) has established guidelines to protect borrowers from illegal and improper lending practices. The agency is warning government workers against excessively high fees and commissions, high interest rates, high-cost credit insurance, and refinancing with higher fees, known as “loan flipping”. CDBO experts have tips for anyone seeking a loan.Shop around: Compare interest rates and total costs of loans by several banks and credit unionsUse caution: Be wary of lenders who contact you first, or offers “only good for a short time”Ask questions: You have a legal right to know the total cost of the loan, the APR, monthly payments, and how long you have to pay it backThink before you sign: Make sure you understand all documents, and consider having someone else check them 2031

There, canine agents made a positive detection and the port's imaging system discovered anomalies inside the vehicles flooring.Agents uncovered 40 packages of methamphetamine hidden in the vehicle.The same day, a tractor-trailer was stopped at the Otay Mesa Port of Entry, arriving from Mexico with a shipment listed as "watermelons and cactus." An officer referred the driver to a secondary inspection, where a canine officer alerted agents to a positive detection in pallets of watermelons.Agents found 311 packages of marijuana, worth an estimated ,557,000, intermixed with the fruit.During another incident on June 16, agents at the San Ysidro Port of Entry stopped a 35-year-old man where a secondary inspection revealed 86 packages of methamphetamine, with a street value of 3,700.All drivers were turned over to Homeland Security agents for processing and all vehicles and narcotics were seized by CBP. 1494

SAN DIEGO (KGTV) - Cathedral Catholic High School students took part in a protest Tuesday against a ban on skirts as uniform options for girls. Officials at the Carmel Valley school changed the dress code Friday for the 2019-2020 school year. CCHS said it would ban the uniform skirts, citing multiple detentions based on enforcement. Female students will have the option to wear pants, capri pants, or Bermuda shorts, the school said. “By removing the option for girls to wear skirts at a Catholic school not only demeans me as a female, but makes me wonder if we are moving towards a gender neutral society. I believe this is sexist, patriarchal and sexualizes the female students unnecessarily,” said freshman student Rachel Donaldson. RELATED: Cathedral Catholic High School girls protest 'sexist' ban on skirtsDonaldson also cited an email about the dress code change she said was sent from Principal Kevin Calkins to parents and students Friday, calling it “disturbing.” “The most disturbing: ‘Male faculty feel uncomfortable addressing female students about the length of their skirts.’ If a male teacher has a problem addressing student's skirt lengths, then they have no business being anywhere near a high school or a female minor. They are there to educate and guide- this is a simple task,” wrote Donaldson. A student created a petition on Change.org to keep skirts as part of the uniform option. By Tuesday afternoon, about 3,000 people had signed online. “It’s not practical to make girls go out and buy new uniforms when they’ve already paid hundreds for the ones they currently wear, our parents are already investing enough money on our education,” said commenter Mia M. on the Change.org petition. “Females should be able to choose what they feel comfortable in and not have their sense of elegance and femininity taken away from them. Making the switch to shorts is no way a practical or ethical solution.” 1933
