Should a high-voltage power line run through California's largest state park? Critics are furious - BERITAJA

BORREGO SPRINGS, Calif. — A planned high-voltage powerfulness statement successful the San Diego County godforsaken has sparked outrage complete its projected way done the bosom of California’s largest authorities park.

At about 650,000 acres, Anza-Borrego Desert State Park is known for its sprawling solitude: miles of lunar stone faces and sandy washes framework spindly Ocotillo stands, wildflower superblooms and designated acheronian skies. But the projected Golden Pacific Powerlink from San Diego Gas & Electric could soon alteration that, opponents say.

The 500-kilovolt transmission statement would tally immoderate 140 miles from an important substation successful southeastern Imperial County, adjacent the Mexican border, to a caller 1 connected the separator of Orange and San Diego counties adjacent the Pacific Ocean — carving a steel-towered way done Anza-Borrego to get there.

The estimated $2.3-billion powerlink is among the largest and about costly projects successful California’s transmission plan, and would link 1 of the state’s awesome coastal organization centers to 1 of its richest renewable power zones. The Imperial Valley is simply a cardinal interconnection constituent for location solar, geothermal and artillery retention projects.

Both the San Diego inferior and the state’s grid manager, the California Independent System Operator (CAISO), opportunity the task is basal for gathering eager c simplification goals and alleviating constraint connected powerfulness lines successful Southern California during precocious demand.

“This would supply a captious pathway to unlock the further procreation that we cognize will beryllium necessary, that will beryllium portion of the request that’s forecasted to summation successful the future,” said Erica Martin, the project’s head of improvement pinch SDG&E. Construction would statesman toward successful 2029 to spell online successful 2032.

The conflict reflects a broader situation successful California: really to move progressively cleanable powerfulness crossed the Golden State while simultaneously preserving the deserts, wildlife habitats and nationalist lands that specify it.

There is nary charismatic tally of really galore different authorities parks person high-voltage transmission lines moving done them, though it is clear Anza-Borrego would not beryllium the first. In 2010, Southern California Edison removed about 40 high-voltage transmission towers from Chino Hills State Park aft years of nationalist opposition.

It’s besides not the first clip this thought has been contested. In 2008, the arguable Sunrise Powerlink faced fierce guidance from biology groups complete its planned way done Anza-Borrego, and yet had to tally beneath it. The way was akin to the 1 projected today, but it was rejected by the California Public Utilities Commission arsenic “environmentally unacceptable and infeasible” because it would consequence successful much than 50 important and unavoidable impacts to the park.

SDG&E maintains that this way is preferable for a number of reasons, including that it would let them to “co-locate” the powerlink pinch the only different energy infrastructure successful the area: a 69-kilovolt statement making love to the 1930s, earlier the parkland was established, which rests connected 50-foot-tall woody poles.

Opponents opportunity the 2 are not comparable. While the weathered woody poles mostly blend into the landscape, the Golden Pacific Powerlink would require a 200-foot right-of-way for its X- aliases Y-shaped alloy lattice towers arsenic gangly arsenic 200 feet, which whitethorn require blinking information lights astatine the top.

“There’s not very galore of these places near wherever you could spell and person axenic wilderness,” said Bri Fordem, executive head of the nonprofit Anza-Borrego Foundation and 1 of the powerlink’s about vocal critics.

The scheme would disrupt the habitats and migration patterns of galore of the park’s 1,500 type of plants and animals, including endangered Peninsular bighorn sheep that are already being hemmed successful by the U.S. separator wall, Fordem said connected a caller hike about the area. It would besides require a uncommon enactment of “un-designating” immoderate of the park’s protected wilderness areas.

Studies person recovered that high-voltage transmission lines could impact wildlife and ecosystems. A 2018 insubstantial published successful the diary Environmental Impact Assessment Review recovered astatine slightest 28 chopped impacts connected biologic diversity, including vertebrate collisions pinch wires, residence fragmentation and loss, and behavioral avoidance by birds, mammals and amphibians. Most of the impacts look successful the early stages of a project, during transmission statement construction, but immoderate persist during operation, the researchers found.

Fordem said she isn’t concerned only about the transmission statement but pinch everything other that could travel pinch it, specified arsenic entree roads, switchyards and different business markers wrong the park. Horizon West, the institution that has been contracted to build the caller substation connected the coast, has already proposed “double-stringing” the line, aliases installing a 2nd group of 500-kilovolt cables to summation the corridor’s power-carrying capacity — a move that could thief meet higher demand.

The task would besides impact recreation, tourism and delicate taste sites, Fordem said, since portion of the statement would beryllium visible from the Tamarisk Grove Campground wrong the park, and different portion would tally on the Angelina Spring Cultural Preserve, a historical archaeological tract tied to the Kumeyaay and different section tribes.

Martin, of San Diego Gas & Electric, said the inferior is weighing each of these factors arsenic it moves forward, and is gathering nationalist feedback earlier filing its general exertion pinch the authorities by the extremity of this year. More than 900 group signed up for virtual nationalist meetings about the task conducted by the inferior earlier this month. The task would besides acquisition authorities and national biology reviews.

Utilities specified arsenic SDG&E make money by building projects specified arsenic transmission lines, which gain regulated returns connected investment.

The costs of the powerlink will beryllium passed on to ratepayers, but it’s excessively early to opportunity really overmuch people’s bills would increase, Martin said. However, she said the magnitude of the statement is the “largest costs driver for the project,” and cutting done the parkland would beryllium overmuch shorter than going about it.

“Regardless of the imaginable merits of caller transmission, routing it done the bosom of California’s largest authorities parkland makes nary sense,” said Brendan Cummings, conservation head pinch the nonprofit Center for Biological Diversity. “If it is yet built astatine all, it perfectly should not beryllium constructed done Anza-Borrego Desert State Park.”

While the inferior primitively touted the project arsenic helping to “integrate much cleanable energy,” that connection has mostly vanished from its nationalist materials. Asked about that, Martin pointed backmost to CAISO, which identified this task on pinch 44 others successful its 2022-2023 transmission plan arsenic basal to thief support the system’s reliability and “unlock entree to renewable procreation resources to meet authorities power needs.”

“All of the electrons that travel crossed the transmission strategy successful California could travel connected this line,” Martin said.

The powerlink has garnered support from members of the San Diego Taxpayers Assn., the Orange County Business Council and the section electrical workers’ union, IBEW 47. Chris Cate, president and main executive of the San Diego Regional Chamber of Commerce, said the task is going done the group’s reappraisal process but it has supported it frankincense far.

“In position of our rationale, it’s successful portion because the authorities has identified this arsenic a must-complete task for helping California meet its ambiance and power goals,” Cate said. “In addition, this task will thief fortify our location and authorities electrical grid capacity and forestall the kinds of rolling blackouts that we’ve seen successful past years and that person negatively impacted businesses and residents.”

Some experts agreed caller transmission projects are important.

“Southern California has a precocious organization density pinch a precocious energy demand, which is projected to proceed increasing substantially,” said Patricia Hidalgo-Gonzalez, head of the Renewable Energy and Advanced Mathematics laboratory astatine UC San Diego.

However, she said location are different cost-effective ways to meet increasing demand, specified arsenic utility-scale and distributed star powerfulness and long-duration power storage.

Hidalgo-Gonzalez said she hasn’t studied SDG&E’s preferred pathway done Anza-Borrego capable to remark connected it. “However, successful principle, and moreover arsenic a powerfulness systems engineer, I judge it is important to prioritize our cultural, ecological and biology assets.”

Others questioned why the San Diego inferior believes the scheme will activity now erstwhile the Sunrise Powerlink was recovered to beryllium environmentally unfeasible successful 2008.

“We already went done this pinch Sunrise, and now they want to do it again,” said Charlie Van Tassel, a Poway resident who besides has a location successful Borrego Springs. Van Tassel was successful the parkland photographing a group of long-eared owls perched successful the trees supra Tamarisk Grove connected a caller weekday morning.

Danny McCamish, elder biology intelligence for the Colorado Desert District of California State Parks, said about of the problems identified backmost past haven’t changed, including impacts to show lines, soundscapes, animal migration patterns and hunting and nesting areas.

“The infrastructure that goes successful ever comes pinch much disturbance,” McCamish said from 1 of the park’s vistas adjacent the Pacific Crest Trail. “We want a complete ecosystem without interruption, and the much we statesman to part and put roads in, and build barriers, and put successful caller pylons and roads about those pylons, the much ‘island’ effect we present.”

McCamish pointed to a adjacent guidelines of cottonwood trees rustling successful the wind.

“We don’t build things that are taller than the autochthonal vegetation,” he said. “And this would break that.”
