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.

City of Oakland Celebrates Reopening of Main Library

“Libraries are such critical facilities for all Oaklanders, whether it’s children coming to story-time, adults reading the newspapers or borrowing the latest novels, and people engaging with a range of services and programs that the library hosts,” said Council President and District 2 Councilmember Nikki Fortunato Bas. “Such library services and programs are only possible when the facility’s electricity, heating, roof, and lighting are fixed and running efficiently. I’m proud to join this re-opening of our Main Public Library.”

The branch had been closed since May for critical infrastructure upgrades

Special to the Post

The City of Oakland leadership and community partners gathered to celebrate the reopening of the Main Library after completion of critical infrastructure upgrades to enhance the library’s facilities and provide a better experience for patrons.

Renovations include new roof installation, skylight repair, critical electrical system upgrades, new boiler control system installation, auditorium heating and cooling system installation, and improvements to lighting, flooring and ceilings throughout the building.

“This is truly something to celebrate, the reopening of our wonderful Main Library! I congratulate the staff and our partners for this important project to make the Main Library a more comfortable place for everyone for years to come, said Oakland Mayor Sheng Thao. “Thank you to Oakland voters and the California State Library for making these crucial improvements possible.”

“Libraries are such critical facilities for all Oaklanders, whether it’s children coming to story-time, adults reading the newspapers or borrowing the latest novels, and people engaging with a range of services and programs that the library hosts,” said Council President and District 2 Councilmember Nikki Fortunato Bas. “Such library services and programs are only possible when the facility’s electricity, heating, roof, and lighting are fixed and running efficiently. I’m proud to join this re-opening of our Main Public Library.”

“Public libraries are a wonderful resource for our residents, offering a safe space for learning and being,” said District 3 Councilmember Carroll Fife. “It is critical to improve and modernize our libraries so more members of our community can utilize and enjoy them. I’m excited that the necessary renovations to the Main Library have been completed successfully and thank everyone involved, particularly the City team, who helped secured the necessary grant funds for this work.”

“I am proud of the City staff and project partners who kept this important project on schedule and under budget,” said Assistant City Administrator G. Harold Duffey. “The library is an incredibly important resource for our community members, and this project is an investment into the library’s future.”

“December 2nd was a momentous occasion for Oakland Public Library as we proudly reopened the doors of the Main Library following extensive infrastructure repairs,” said Director of Library Services Jamie Turbak. “Closing the Main Library for six months was no easy decision, as it serves as the central hub for our library system and is truly the heart of Oakland. Yet, this renovation was essential, representing more than just physical upgrades—it reflects our ongoing commitment to creating a safe, welcoming space for everyone.”

The City Administrator Jestin Johnson also attended the press conference and signalled his support for the completion of the record-setting completion of the renovations. Gay Plair Cobb, a newly appointed Library Commissioner said the Library represents the soul and brains of our community.

The Oakland Public Library secured funding for these crititcal repairs through a variety of sources. The California State Library’s Building Forward Library Facilities Improvement Program awarded the Main Branch $4.2 million. To comply with the grant terms, the City of Oakland provided matching funds through Measures KK, as approved by the Oakland City Council in October 2023.

The Main Library will host an Open House to celebrate the reopening on February 22, 2025, 10 a.m. – 5:00 p.m.

Biden’s Legacy Secured with Record-Setting Black Judicial Appointments

His record surpasses previous efforts by his predecessors. President Jimmy Carter appointed 37 Black judges, including seven Black women. In stark contrast, Donald Trump’s first term resulted in only two Black women appointed out of 234 lifetime judicial nominations. The White House said Biden’s efforts show a broader commitment to racial equity and justice.

President Joe Biden’s commitment to diversifying the federal judiciary has culminated in a historic achievement: appointing 40 Black women to lifetime judgeships, the most of any president in U.S. history.

Biden has appointed 62 Black judges, cementing his presidency as one focused on promoting equity and representation on the federal bench.

His record surpasses previous efforts by his predecessors. President Jimmy Carter appointed 37 Black judges, including seven Black women. In stark contrast, Donald Trump’s first term resulted in only two Black women appointed out of 234 lifetime judicial nominations.

The White House said Biden’s efforts show a broader commitment to racial equity and justice.

Meanwhile, Trump has vowed to dismantle key civil rights protections, including the Justice Department’s Civil Rights Division.

“Having the Black woman’s experience on the federal bench is extremely important because there is a different kind of voice that can come from the Black female from the bench,” Delores Jones-Brown, professor emeritus at John Jay College of Criminal Justice, told reporters.

Lena Zwarensteyn of the Leadership Conference on Civil and Human Rights told reporters that these district court judges are often the first and sometimes the final arbiters in cases affecting healthcare access, education equity, fair hiring practices, and voting rights.

“Those decisions are often the very final decisions because very few cases actually get heard by the U.S. Supreme Court,” Zwarensteyn explained.

Biden’s nomination of Justice Ketanji Brown Jackson to the Supreme Court further reflects his commitment to judicial diversity. Jackson became the first Black woman to serve on the nation’s highest court.

Patrick McNeil, spokesperson for the Leadership Conference, pointed out that over half of Biden’s Black female judicial appointees have backgrounds as civil rights attorneys and public defenders, experience advocates consider essential for a balanced judiciary.

Meanwhile, Congress remains divided over the expansion of federal judgeships. Legislation to add 66 new judgeships—approved unanimously by the Senate in August—stalled in the GOP-controlled House until after the election. House Republicans proposed distributing the new judgeships over the next decade, giving three administrations a say in appointments. President Biden, however, signaled he would veto the bill if it reached his desk.

Rep. Jerry Nadler, D-N.Y., argued the delay was a strategic move to benefit Trump’s potential return to office. “Donald Trump has made clear that he intends to expand the power of the presidency and giving him 25 new judges to appoint gives him one more tool at his disposal,” Nadler said.
