May 15, 2026 (San Diego County) — Four virtual open house meetings about the Golden Pacific Powerlink  provided hundreds of online attendees insight on the proposed grid that will bring a 500-kilovolt transmission line project of around 150 miles, spanning from outside of El Centro to San Onofre.

The new energy line has been in the plans for several years, with California energy leaders projecting a significant surge in electricity needs through 2045. The Powerlink is planned as a way to meet that demand for reliable electricity for homes, transportation, businesses and industry in the state.


The Powerlink is a massive 500 kV (carrying 500,000 volts) transmission project that is intended to stabilize California’s aging and congested power grid, and part of the state’s vision since 2023 for strengthening the statewide grid.


The proposed 145-mile line of towers would connect the renewable energy hub of Imperial Valley to a new substation on the border of San Diego and Orange counties — a geographic area known as “North of SONGS,” referencing its proximity to the decommissioned San Onofre Nuclear Generating Station.

On May 14, the final two of four virtual open houses held this past week offered an overview of the project. With a host and six panelists connected to the project, the meetings, spearheaded by San Diego Gas & Electric, drew hundreds of online attendees.


After a half hour explainer, the open houses allowed for a Q&A that went over concerns like costs (estimated at $2.3 billion to start) and electromagnetic fields (downplayed by the panel), as well as fire safety concerns and its current route that enters and exits in part of the Anza-Borrego Desert State Park (see below for more comprehensive coverage).


Additional open houses are expected to come in the coming months, with environmental studies and permitting approvals to follow, but current plans show a projected timeline of construction to begin in fall of 2029.


Myles Still, principal engineer assigned to the project, told listeners at the open house that the structure heights anticipated as part of the project show a range of 125 feet to 190 feet “at this point in time.” He said the span of lengths of the distance between structures “would be approximately 1,400 feet to 1,800 feet.”

Still said that part of what drives the span lengths and the heights of the towers include topography, water crossings, environmental resources and cultural resources.


Wildfires and electrical transmission


Locals for more than a decade raised concerns about the Sunrise Powerlink, the nearly 120-mile long transmission line finished in 2012 that stretches from the Imperial Valley to the Sycamore Canyon and Peñasquitos substations.


While operating the transmission line has thus far not sparked any major wildfires, several small construction-related fires were sparked during its building phase in 2011.


According to the Western Fire Chiefs Association, between 2016 and 2020, electrical power networks caused 19 percent of the wildfires that occurred in those five years. With the growing risk of wildfires amid climate change, there is heightened concern about electrical power conductors igniting wildfires.

Power lines can ignite wildfires in several ways — from downed lines to vegetation contact — but which can largely be prevented through proper mitigation tactics.


Regarding wildfire concerns and mitigation shared by several at the open house, Melinda Keesee, manager of major construction for the project, said that wildfire prevention and SDG&E’s resiliency measures “will be fully integrated into the design, construction, and ultimately operations and maintenance.”


Keesee added that “Wildfire risk, and more specifically public safety shutdowns in high fire threat areas, really is an important reason why the route is in a new corridor and not in an existing corridor with some of our other major transmission lines.”


Background and costs


While SDG&E is the current developer, the utility did not originally propose the Powerlink.

The project originated through the California Independent System Operator as part of a state-mandated planning process. CAISO, whose board is appointed by the governor and confirmed by the California State Senate, identified the need in its 2022–23 Transmission Plan to address renewable energy integration and future demand growth.


The project was initially awarded to Horizon West Transmission, a subsidiary of NextEra Energy, via competitive bidding.


In August 2025, responsibility for the transmission line was assigned to SDG&E under CAISO tariff rules, while Horizon West retained responsibility for the North of SONGS substation.


Much of the current preliminary route design originated from the original Horizon West proposal.

The costs are not necessarily going to stay at the $2.3 billion mark.


Erica Martin, director of project development, said “because we are in a very preliminary phase of project development we do not have a current cost estimate to provide, but we are actively working to develop that.”

Martin said that will be a necessary part of its application to the California Public Utilities Commission. She said more information on costs will be provided “by the end of Q2 this year.”


She said that while they will be able to share a “very preliminary cost estimate… folks will also have to keep in mind that the one of the key drivers of cost for this project is the route. Where is it going to be? How long is the route? That length of the route is a key maybe the biggest driver of the bottom line for the project.”


Martin noted that construction costs and the procurement of materials “is the biggest needle mover in terms of increasing or decreasing cost, so determining where the route is and how long it is will ultimately impact that number.”


Whatever the cost, Martin said SDG&E is keeping affordability for ratepayers as one of its top concerns. And those ratepayers extend beyond San Diego County.


“Because this is project that is part of our statewide transmission system under CAISO’s jurisdiction, the costs of the project are shared across all customers in CAISO’s jurisdiction, so not just SDG&E customers or (Southern California) Edison customers, but all of the investor-owned utilities… share of the cost for this project.”


Anza-Borrego Desert State Park in a quandary


Already it appears that the most complex segment of plan involves Anza-Borrego Desert State Park — California’s largest state park. It presents a significant obstacle for any line heading west from the Imperial Valley.


For many East County residents, the proposed route evokes immediate memories of the Sunrise Powerlink, the last major 500 kV transmission line SDG&E built.


Gerard Ellison, senior environmental project manager for the Golden Pacific Powerlink, acknowledged that “there were lessons learned from Sunrise” and the successful mitigation of existing right-of-ways.


The Sunrise project sparked years of fierce environmental and community opposition before it was ultimately carved through Anza-Borrego and energized roughly 13 years ago. During the public meetings, residents were quick to draw comparisons, questioning why another massive line was needed through the protected park.

On the Anza Borrego Park Foundation’s website, the nonprofit wrote:

“The Golden Pacific Powerlink is one of the largest and most expensive transmission projects in California’s current grid planning — estimated to cost ratepayers $2.3 billion. It was identified in CAISO’s 2022–2023 Transmission Plan as essential for grid reliability, clean energy integration, and reducing congestion across Southern California’s electrical system. 


“In practical terms, a 500 kV line is the highest-voltage class of transmission infrastructure built in California. The towers required to carry these lines can stand 150 to 200 feet tall, the height of a 15- to 20-story building with a cleared right-of-way stretching hundreds of feet wide. For context, the only existing transmission line within the Park today is a 69 kV line on modest wooden poles, barely visible against the landscape. That line was constructed before the Park was established in 1933 and before the California Environmental Quality Act (CEQA) existed (1970) — it would not be permitted today.”


SDG&E officials acknowledged the history but stressed that the political and environmental landscape is “literally and figuratively different” than it was two decades ago when Sunrise was planned. With California’s aggressive new decarbonization mandates, the state must now transport significantly larger amounts of clean energy generated in the east to coastal population centers.


“There is no silver bullet route that allows us to avoid all impacts,” Martin said.


Officials explained that the park extends almost to the international border, making it “infeasible” to bypass it to the south without hitting existing, highly congested infrastructure.


Instead, the preliminary route roughly follows the highway corridor and existing infrastructure through the park, running south of the Borrego Springs community, to minimize its footprint on untouched desert land. The utility also noted it plans to apply mitigation lessons learned from the Sunrise project, such as utilizing off-site habitat enhancements to protect local pollinators and sensitive desert wildlife.


North County and Temecula impact


After leaving the desert near Grapevine Canyon, the route turns northwest, following the Highway 79 corridor. The line is slated to pass through Warner Springs and east of Palomar Mountain before entering the Temecula area.


Residents raised concerns about visual impacts and local recreation. One person asked in the chatroom about the region’s popular hot air balloon industry.


Ellison noted that the team is “approaching this with eyes wide open” regarding aviation flyways and sensitive habitats like Temecula Creek. He emphasized that “micro-siting” — adjusting tower placements by small margins — will be used to mitigate impacts on cultural sites and rare species.


SDG&E maintains the new corridor is vital for wildfire resiliency. By placing the Powerlink in a geographically distinct location from existing 500 kV lines, the grid can remain operational even if one corridor is shut down for public safety or emergency events.


The project is currently in the data-gathering and public outreach phase. SDG&E anticipates submitting a formal application to the California Public Utilities Commission in 2026. If the multi-year review process is successful, construction could begin in 2029, with a target service start date of 2032, according to SDG&E.


Undergrounding lines


A recurring question from the public, at all the open houses, has been whether or not the high-voltage lines could be placed underground.


State officials have said that burying neighborhood distribution lines costs between $1.8 million and $6.1 million per mile and that undergrounding high-voltage 500 kV lines can cost 30 to 50 times the cost of an equivalent overhead line.


Keesee said that underground transmission lines are going to be evaluated as part of the early project planning but acknowledged that “for a project of this size, a line of this size, the voltage, it presents significant challenges.”


“Given this is a high-voltage transmission line that would span long distances, across varied terrain, very much including remote and environmentally sensitive areas, undergrounding construction is dramatically more expensive than overhead construction and can be significantly more complex to just build, operate and then ultimately maintain in those areas,” she said.


She said undergrounding wires “would require extensive excavation and construction activity across the entire corridor — versus a smaller footprint of tower locations, which can increase environmental and community impacts rather than reduce them, which is often the goal.”


She reiterated that high-voltage transmission lines are typically built overhead for all those reasons, but said undergrounding “will continue to be evaluated as the project moves through the permitting process.”

There are photographers who chase spectacle, and there are photographers who quietly ask people to slow down and look more carefully. The work of Brice Weaver belongs firmly in the latter. Through film photography, remote landscapes, abandoned spaces, layered histories, and reflective atmosphere, Weaver explores ideas surrounding memory, impermanence, and the traces humanity leaves behind. His images often feel suspended somewhere between documentary observation and emotional archaeology, asking viewers not simply to look at a place, but to consider who stood there before, what remains after time passes, and how photography itself becomes evidence that something briefly existed. From trekking to Everest Base Camp carrying the cremated remains of a fallen Marine Corps brother, to diving with great white sharks in fulfillment of a childhood dream inspired by Jacques Cousteau, Weaver’s photographic journey is deeply tied to exploration, personal reflection, and the emotional relationship between people and place. We spoke with Weaver about photography, memory, travel, film, and the evolving body of work he calls Evidence. Photography & Creative Beginnings “My interest in photography really began long before I ever owned a serious camera,” Weaver says. “Growing up around Washington D.C., some of my earliest school field trips were to places like the Smithsonian and the National Gallery of Art.” Those early experiences left a lasting impression. “I still vividly remember standing in front of the massive Megalodon jaws at the Smithsonian as a kid, completely in awe, and thinking, ‘That’s what I want to do someday.’ At the time, I was obsessed with the expeditions of Jacques Cousteau and dreamed about exploring the ocean and diving with sharks myself one day.” He also recalls standing in front of paintings such as Daniel in the Lions’ Den at the National Gallery and being struck by the emotional atmosphere they carried. “At home, I would spend hours in my grandparents’ basement reading old National Geographic magazines and musty volumes of Encyclopaedia Britannica, completely fascinated by exploration, history, wildlife, and distant places.” Photography eventually entered his life during a period of uncertainty. “At the time, I was working on an ambulance and had taken time off to hike the Pacific Crest Trail. Around mile 250, an old hip injury from the Marines resurfaced badly enough that I eventually needed surgery. Suddenly I went from constantly moving and working in high-intensity environments to being laid up in bed wondering what came next.” During recovery, he reflected on the photographs he had casually taken during his travels. “People had responded well to photos I was taking on my phone and GoPro, and eventually I thought, why not actually buy a real camera and take it seriously?” What began as a creative outlet quickly became something deeper. “I realized the camera was changing the way I observed the world. I became less interested in simply documenting places and more interested in atmosphere, memory, light, and the emotional weight certain environments carry.” Exploration, Travel & Perspective For Weaver, travel has always represented more than movement. “A lot of my creative influences came less from photography specifically and more from exploration, atmosphere, and visual storytelling,” he explains. “There was always this sense of discovery, history, and wonder tied to imagery for me.” That fascination eventually took him across environments ranging from the Amazon and Peru to Nepal and Patagonia. One journey in particular remains deeply personal. “Trekking to Everest Base Camp was deeply meaningful for me,” he says. “One of my closest friends from the Marine Corps, someone I served with in Iraq and who was like a brother to me, and I used to talk about making that journey someday.” After his friend was murdered unexpectedly, Weaver decided to carry some of his cremated remains with him to Everest Base Camp. “So the trek became much more than just travel or adventure. There were moments on that mountain where I found myself thinking about friendship, mortality, memory, and how small we really are within landscapes that have existed for thousands of years.” Those experiences altered not only his worldview, but the way he approaches photography itself. “The more I’ve explored the world, the more I’ve realized how small we are within the larger scope of history, nature, and time. I think that perspective has shaped not only the way I photograph, but the way I move through life in general.” Travel, he says, has also taught him adaptability. “Travel places you into unfamiliar environments constantly, different cultures, languages, conditions, and situations where you have to learn to navigate uncertainty and trust yourself. There have been moments ranging from communication barriers in remote places to genuinely dangerous situations, including one experience in Nepal that almost resulted in me being kidnapped, which is probably a story for another day.” A Full Circle Beneath the Surface One of the most unforgettable moments of Weaver’s career came underwater at Guadalupe Island. “Growing up, I had spent countless hours fascinated by sharks, ocean exploration, and the expeditions of Jacques Cousteau ever since I was a kid standing in awe beneath the Megalodon jaws at the Smithsonian,” he says. Years later, that childhood fascination came full circle while photographing great white sharks. “One experience I’ll never forget was diving with great white sharks and photographing the image that later became known as Great Bite . What stayed with me most was the sense of respect and presence you feel underwater with an animal like that. There’s an intensity to it, but also an incredible calm. Everything becomes very quiet and focused.” The photograph would later receive international recognition and become one of his most widely known images. “Looking back, I think that photograph became meaningful to me not just because of the recognition it later received, but because it represented the realization of something that had lived in my imagination since childhood.” Atmosphere, Memory & Evidence Much of Weaver’s work focuses on subtle details, quiet environments, and traces of human presence. “What usually stops me first is light, specifically the way it interacts with a subject or environment and creates atmosphere,” he explains. “But beyond that, I’m often drawn to places because of the sense of history and human presence they carry.” He recalls sitting on a hillside overlooking the Acropolis in Greece and imagining the continuity of human experience across centuries. “I found myself thinking that I could quite literally be standing in the same place where someone like Socrates once stood thousands of years ago. Moments like that change the way you experience a landscape. It stops feeling like scenery and starts feeling connected to memory, history, and human continuity.” That fascination with traces of existence has become central to his evolving body of work. “I think I’m often responding to evidence of people more than the places themselves. When I encounter an abandoned building, a quiet landscape, or subtle traces left behind, I find myself wondering who those people were, what their lives were like, and what that place felt like in its prime.” For Weaver, photography exists in a complicated relationship with time. “Memory plays a significant role in my work because I think photography exists in this strange space between preservation and impermanence. On one hand, a photograph acts as evidence that something existed, a place, a moment, a specific atmosphere in time. But at the same time, even the things we photograph remain vulnerable to change, decay, and disappearance.” He points to his award-winning photograph Deserted Refuel as an example. “I recently went back to that location after the image had already received recognition. Part of the building had burned down, and even the graffiti on the gas station canopy had completely changed from what appears in the photograph. It was a reminder that the image had already become a document of something that no longer fully exists in the same way.” That realization helped shape the conceptual direction of his broader body of work, Evidence . “If I had to summarize my work philosophically, I think it revolves around evidence of existence and the fleeting nature of time. We are only here for an incredibly brief moment within a much larger continuum of history and existence, and photographs become small records of those moments before they disappear or change.” Film, Presence & Intentionality Although Weaver works across both film and digital formats, analog photography remains deeply important to his process. “What keeps me connected to analog film photography is the level of presence and intentionality it requires,” he says. “With film, every frame matters. When I press the shutter, I’ve consciously decided that particular moment is worth preserving.” For him, film photography changes not only the image, but the photographer. “With digital, there’s often an element of instant gratification, you can immediately review images, adjust, and continue shooting. Film removes that safety net entirely.” The uncertainty, he says, is part of the emotional connection. “With film, there’s always a degree of trust involved. So many factors exist outside your control, from how the film was stored, to lab processing, to whether airport security refuses to hand check it and sends it through scanners. You don’t fully know what you captured until much later.” Oddly enough, that unpredictability has become part of the appeal. “Getting scans back from a roll of film almost feels like opening a Christmas present because there’s still an element of discovery involved. Sometimes imperfections or unexpected moments become part of what gives the image character and emotional weight.” Recognition & Creative Growth Recognition arrived relatively quickly after Weaver first picked up a camera. “Not long after buying my first DSLR, I was already being published in places like Backpacker Magazine, and then receiving recognition such as the International Photography Awards Honorable Mention for Great Bite in 2019.” One moment still stands out vividly. “I remember attending the IPA gala in New York City wearing a black tie tuxedo and suddenly finding myself standing next to Annie Leibovitz. It was one of those moments where I had to pause and think about how unexpected the entire journey had been.” Despite the accolades, Weaver says recognition has not fundamentally changed his creative direction. “I still create the work I feel personally drawn to and photograph environments the way I naturally see and experience them. I think if you start chasing recognition too heavily, it can pull you away from authenticity and toward trying to predict what other people want to see.” The greater challenge, he says, has been visibility. “One of the biggest challenges in growing as a photographer has been simply being seen in an environment where attention moves incredibly fast. Social media algorithms tend to reward constant output, speed, and short attention spans, while a lot of the work I’m interested in creating is slower, more reflective, and asks people to spend time with an image.” Reflection & What Comes Next When asked what he hopes viewers experience through his work, Weaver’s answer is simple. “Curiosity and reflection.” “I’m more interested in creating images that invite people to slow down, look more carefully, and spend time thinking about what they’re seeing.” As for inspiration, he still returns to the same sources that shaped him early on. “I think staying creatively inspired starts with staying true to yourself and remaining curious about the world around you. For me, inspiration often comes less from social media and more from physically experiencing places, museums, galleries, history, travel, and simply paying attention.” And his advice to younger photographers? “Don’t become overly consumed with gear or the idea that equipment alone creates meaningful work. Far more important is developing your eye, learning how to observe, recognize atmosphere and emotion, and tell a story through an image.” Looking ahead, Weaver is preparing for the next chapter of his creative journey. “Right now, one of the things I’m most looking forward to is attending Les Rencontres d’Arles in France. It’s an opportunity to immerse myself in a space centered around photography, conversation, and creative exchange at an international level.” He also plans to continue expanding Evidence , the interconnected body of work exploring memory, atmosphere, and human presence through film photography. “I’m increasingly interested in creating work that feels interconnected conceptually rather than just individual images,” he says. And perhaps no place reflects those ideas more naturally than the desert community he now calls home. “What I love about Borrego Springs is the silence, the space, the light, and the sense of time that exists there. It’s an environment that constantly reminds you how temporary we are compared to the landscapes around us. I think that perspective inevitably finds its way into my work.” Learn more about Brice Weaver here: briceweaverphotography.com
