Utility companies in the United States could double electric transmission capacity by 2035 by replacing existing transmission lines with those made from advanced materials, according to a new study published Monday in the Proceedings of the National Academy of Sciences.

Led by Duncan Callaway, professor and chair of the Energy and Resources Group (ERG), and Amol Phadke, an affiliate and senior scientist at the Goldman School of Public Policy, the first-of-its-kind study details a faster and more cost-effective way to expand the grid and connect the more than 1,200 gigawatts of renewable energy projects awaiting approval. The analysis was first published last December as a working paper by the Energy Institute at Haas and has been covered by the New York Times, the Washington PostHeatmap News, and other news outlets.

“Expanding transmission capacity is critical to decarbonization, and we sought to study ways to build it faster and cheaper,” said Callaway.

It currently takes 10 to 15 years to build a new power line and the U.S. is building transmission lines at a lower rate than it was in the past decade. Without sufficient capacity, renewable energy projects often sit in limbo for years as transmission operators study what upgrades—if any—are needed to accommodate the increased loads.

The authors modeled various scenarios to determine if replacing existing transmission conductors with those made with advanced composite-core materials—a process known as reconductoring—could provide a pathway to faster grid expansion. 

Several reconductoring projects have been initiated in Belgium and the Netherlands, and utility companies in the U.S. have used the material to string transmission lines across wide spans like river crossings. That technology, however, has not made its way to the majority of overhead power lines that feed residential and commercial customers.

“As we learned more about the technology, we realized that no one had done the detailed modeling needed to understand the technology’s potential for large-scale transmission capacity increases,” said Phadke.

Based on the authors’ projections, it is cheaper—and quicker—for utility companies to replace the 53,000 existing transmission lines with advanced composite-core materials than it is to build entirely new transmission lines.

They assert that doing so would reduce wholesale electricity costs by 3% to 4% on average—translating to $85 billion in system cost savings by 2035 and $180 billion by 2050.

“The level of interest we’ve received from federal and state agencies, transmission companies and utilities is extremely encouraging, and since our initial report, the Department of Energy has committed hundreds of millions of dollars to reconductoring projects,” said co-author Emilia Chojkiewicz, a PhD student in ERG and an affiliate of the Goldman School of Public Policy. “We are looking forward to learning about these projects as they unfold.”

Additional co-authors include Nikit Abhyankar and Umed Paliwal, affiliates at the Goldman School of Public Policy; and Casey Baker and Ric O’Connell of GridLab, a nonprofit that provides comprehensive technical grid expertise to policy makers and advocates.

UPDATE: PepsiCo Meets with Sharpton Over DEI Rollbacks, Future Action Pending

BLACKPRESSUSA NEWSWIRE — The more than hour-long meeting included PepsiCo Chairman Ramon Laguarta and Steven Williams, CEO of PepsiCo North America, and was held within the 21-day window Sharpton had given the company to respond.

Rev. Al Sharpton met Tuesday morning with PepsiCo leadership at the company’s global headquarters in Purchase, New York, following sharp criticism of the food and beverage giant’s decision to scale back nearly $500 million in diversity, equity, and inclusion (DEI) initiatives. The more than hour-long meeting included PepsiCo Chairman Ramon Laguarta and Steven Williams, CEO of PepsiCo North America, and was held within the 21-day window Sharpton had given the company to respond. Sharpton was joined by members of the National Action Network (NAN), the civil rights organization he founded and leads. “It was a constructive conversation,” Sharpton said after the meeting. “We agreed to follow up meetings within the next few days. After that continued dialogue, NAN Chairman Dr. W. Franklyn Richardson and I, both former members of the company’s African American Advisory Board, will make a final determination and recommendation to the organization on what we will do around PepsiCo moving forward, as we continue to deal with a broader swath of corporations with whom we will either boycott or buy-cott.”

Sharpton initially raised concerns in an April 4 letter to Laguarta, accusing the company of abandoning its equity commitments and threatening a boycott if PepsiCo did not meet within three weeks. PepsiCo announced in February that it would no longer maintain specific goals for minority representation in its management or among its suppliers — a move that drew criticism from civil rights advocates. “You have walked away from equity,” Sharpton wrote at the time, pointing to the dismantling of hiring goals and community partnerships as clear signs that “political pressure has outweighed principle.” PepsiCo did not issue a statement following Tuesday’s meeting. The company joins a growing list of major corporations — including Walmart and Target — that have scaled back internal DEI efforts since President Donald Trump returned to office. Trump has eliminated DEI programs from the federal government and warned public schools to do the same or risk losing federal funding. Sharpton has vowed to hold companies accountable. In January, he led a “buy-cott” at Costco to applaud the retailer’s ongoing DEI efforts and announced that NAN would identify two corporations to boycott within 90 days if they failed to uphold equity commitments. “That is the only viable tool that I see at this time, which is why we’ve rewarded those that stood with us,” Sharpton said.

Target Reels from Boycotts, Employee Revolt, and Massive Losses as Activists Plot Next Moves

BLACKPRESSUSA NEWSWIRE — Target is spiraling as consumer boycotts intensify, workers push to unionize, and the company faces mounting financial losses following its rollback of diversity, equity, and inclusion (DEI) initiatives.

Target is spiraling as consumer boycotts intensify, workers push to unionize, and the company faces mounting financial losses following its rollback of diversity, equity, and inclusion (DEI) initiatives. With foot traffic plummeting, stock prices at a five-year low, and employee discontent boiling over, national civil rights leaders and grassroots organizers are vowing to escalate pressure in the weeks ahead. Led by Georgia pastor Rev. Jamal Bryant, a 40-day “Targetfast” aligned with the Lenten season continues to gain traction. “This is about holding companies accountable for abandoning progress,” Bryant said, as the campaign encourages consumers to shop elsewhere. Groups like the NAACP, the National Newspaper Publishers Association, and The People’s Union USA are amplifying the effort, organizing mass boycotts and strategic buying initiatives to target what they call corporate surrender to bigotry.

Meanwhile, Target’s workforce is in an open revolt. On Reddit, self-identified employees described mass resignations, frustration with meager pay raises, and growing calls to unionize. “We’ve had six people give their two-week notices,” one worker wrote. “A rogue team member gathered us in the back room and started talking about forming a union.” Others echoed the sentiment, with users posting messages like, “We’ve been talking about forming a union at my store too,” and “Good on them for trying to organize—it needs to happen.” Target’s problems aren’t just anecdotal. The numbers reflect a company in crisis. The retail giant has logged 10 straight weeks of falling in-store traffic. In February, foot traffic dropped 9% year-over-year, including a 9.5% plunge on February 28 during the 24-hour “economic blackout” boycott organized by The People’s Union USA. March saw a 6.5% decline compared to the previous year. Operating income fell 21% in the most recent quarter, and the company’s stock (TGT) opened at just $94 on April 14, down from $142 in January before the DEI cuts and subsequent backlash. The economic backlash is growing louder online, too.

“We are still boycotting Target due to them bending to bigotry by eroding their DEI programs,” posted the activist group We Are Somebody on April 14. “Target stock has gone down, and their projections remain flat. DEI was good for business. Do the right thing.” Former congresswoman Nina Turner, a senior fellow at The New School’s Institute on Race, Power and Political Economy, wrote, “Boycotts are effective. Boycotts must have a demand. We will continue to boycott until our demands are met.” More action is on the horizon. Another Target boycott is scheduled for June 3–9, part of a broader campaign targeting corporations that have abandoned DEI initiatives under pressure from right-wing politics and recent executive orders by President Donald Trump. The People’s Union USA, which led the February 28 boycott, has already launched similar weeklong actions against Walmart and announced upcoming boycotts of Amazon (May 6–12), Walmart again (May 20–26), and McDonald’s (June 24–30). The organization’s founder, John Schwarz, said the goal is nothing short of shifting the economic power balance.

“We are going to remind them who has the power,” Schwarz said. “For one day, we turn it off. For one day, we shut it down. For one day, we remind them that this country does not belong to the elite, it belongs to the people.” As for Target, its top executives continue to downplay the damage. During a recent earnings call, Chief Financial Officer Jim Lee described the outlook for 2025 as uncertain, citing the “ripple” effects of tariffs and a wide range of possible outcomes. “We’re going to be focusing on controlling what we can control,” Lee said. But discontent is spreading internally. A Reddit post from a worker claimed, “The HR rep is doing his best to stop the bleeding, but all he did was put a Bluey band-aid on what is essentially a severed limb.”

Several employees criticized the company’s internal rewards system, “Bullseye Bucks,” for offering what amounts to play money. “Can’t pay rent or buy food with Bullseye Bucks,” one wrote. Others urged their colleagues to join unionizing efforts. “Imagine how much Target would lose their mind if they were under a union contract,” one team leader wrote. “It needs to happen at this point.” One former manager said they left the company after an insulting raise. “Quit last year when they gave me a 28-cent raise. Best decision I’ve ever made.” From store floors to boardrooms, the pressure is growing on Target. And as calls for justice, equity, and worker rights get louder, one worker put it plainly: “We’re all screwed—unless we fight back.”
