A large-scale renewable energy project proposed jointly by the City of San Diego and the San Diego County Water Authority received $18 million in the state budget signed this week by Gov. Gavin Newsom, enough to advance the San Vicente Energy Storage Facility through initial design, environmental reviews, and the federal licensing process.
The San Vicente energy project is one of the most promising pumped energy storage solutions in California and it would be a major asset to help avoid rolling blackouts through on-demand energy production while helping to meet state climate goals. It also could mitigate costs for water ratepayers across the San Diego region by generating additional revenue to help offset the cost of water purchases, storage, and treatment. The City and the Water Authority are developing the project together, just like they did to raise the height of the city-owned San Vicente Dam 117 feet in the 2010s.
Upon completion, the San Vicente energy project would provide up to 500 megawatts of long-duration stored energy, which will assist in meeting peak electrical demand periods throughout Southern California and help meet the goals of Senate Bill 100, which requires 60% renewable energy by 2030 and 100% zero-carbon energy resources statewide by 2045. The project will provide enough energy for about 135,000 households when operating.
“I want to thank Governor Newsom, Senate President pro Tempore Toni G. Atkins, Assembly Speaker Anthony Rendon and all the members of the Legislature for funding a vital San Diego project that will help us provide reliable, clean energy,” said San Diego Mayor Todd Gloria. “This innovative partnership with the San Diego County Water Authority will help our City meet its climate goals while building sustainable infrastructure and supporting good-paying local jobs.”
Water Authority Board Chair Gary Croucher also highlighted the work of state leaders and staff at both agencies who have been collaborating on project plans for years.
“The San Vicente Energy Storage Facility will reduce the chances for rolling blackouts by storing renewable energy for use when it’s needed most,” Croucher said. “We owe a debt of gratitude to Gov. Gavin Newsom and Senate President pro Tempore Toni G. Atkins for ensuring funding for this critical infrastructure project, which will create more than 1,000 construction-related jobs in addition to its other benefits.”
With state funding in place, the Water Authority and the City are preparing to launch federal and state environmental reviews, seek a project license from the Federal Energy Regulatory Commission, and issue a Request for Proposals for a full-service private partner to help develop the project. Those complex components are expected to take at least four years, with construction completion forecast for 2030.
“California has a proud history of adopting forward-thinking solutions to our biggest challenges, and the San Vicente Energy Storage Project is no exception,” said Sen. Atkins of San Diego. “This may well be a pivotal moment in our statewide efforts to meet peak power needs and maximize our use of renewable energy.”
California sources nearly one-third of its power from renewables, mainly solar and wind. The target for renewable energy in California is 60% by 2030. Such a major shift to renewables will require new kinds of investments, markets, and business practices. Electric grids need to be more flexible; new kinds of power supplies will help deliver energy flexibility when needed; and new pricing systems are needed to send clear signals to developers and financial markets that these projects need to move forward.
Pumped energy storage projects are a major piece of the solution. They are designed to store excess renewable energy from solar and wind during the day, and then discharge that energy when energy use increases in the evening and renewable energy is not available.
The San Diego County Water Authority and the City of San Diego are partners in developing the San Vicente Energy Storage Facility. The pumped storage energy project at San Vicente Reservoir could store 4,000 megawatt-hours per day of energy, or 500 megawatts of capacity for eight hours.
The San Vicente project would create a small upper reservoir above the existing San Vicente Reservoir in Lakeside, along with a tunnel system and an underground powerhouse to connect the two reservoirs. The powerhouse would contain four reversible pump turbines.
During off-peak periods – when power is inexpensive and renewable supplies from wind and solar facilities exceed demand – turbines would pump water to the upper reservoir where it would act as a battery of stored potential energy. During high energy use, the system would discharge water from the upper reservoir downhill through the turbines, producing energy. The exchange between the two reservoirs would not consume water.
San Vicente Reservoir is near major electricity transmission interconnection facilities, which would allow the project to play a central role in integrating solar and wind energy from across the Southwest for use in San Diego County. The San Vicente project is largely immune to the challenges faced by some conventional hydropower facilities because it is a closed-loop system that mainly holds imported water and is not reliant on runoff that can fluctuate significantly from year to year and hamper power production.

With 500,000 acres of farmland in the Imperial Valley, agriculture continues to not only be vital to the economy of the region, but now perhaps more than ever the crops grown on that land are critical to the entire country and a world that is recovering from the COVID-19 pandemic.
Considering just how essential Imperial Valley agriculture is, strong voices ready to advocate on behalf of the farming community are pivotal — especially considering the ongoing challenges farmers face, like increasing costs of production and an ongoing need to protect the Valley’s water rights during this time of drought, as they work to get their crops from the fields to dinner tables.
When the San Diego County Water Authority adopted the Permanent Special Agricultural Water Rate, the SDCWA also adopted eligibility criteria but allowed previous Temporary Special Agricultural Water Rate customers a six-month grace period to establish eligibility. The CWA extended that transitional eligibility period by an additional two months June 24. The unanimous CWA board vote extends the temporary eligibility period to Aug. 31. Although the six CWA member agencies who requested an extension of the eligibility period sought a six-month extension, the CWA’s Financial Strategy Working Group recommended the two-month extension which was approved by the CWA board.
Sandra Kerl talks about how the San Diego County Water Authority is adapting and innovating for this year’s drought and beyond, while continuing to provide reliable service to customers and reshaping the Water Authority’s internal processes, values and structure.
As California continues to face a drought brought on by record-breaking temperatures, Gov. Gavin Newsom is asking residents to reduce their water usage by 15%. However, this request does not apply to San Diego County.
Sandra Kerl, General Manager at the San Diego County Water Authority, joined KUSI’s Logan Byrnes on Good Evening San Diego to discuss what “America’s Finest City” is doing right.
Kerl explained that due to a “portfolio” of different water supplies and long-term conservation efforts, the city has enough water supply for now, despite the state’s drought.
On July 8, Gov. Gavin Newsom expanded two earlier drought emergency declarations to cover 50 of the state’s 58 counties. In May, he directed state agencies to consider easing requirements for reservoir releases to conserve water upstream, and to make water transfers easier. Both are needed.
Notably, the governor’s emergency proclamation did not impose water conservation mandates. Instead, Gov. Newsom is leaving water conservation to each region — a smart and necessary approach that incentivizes regional investments in water supply.
Emergency conservation orders address short-term water shortages, but don’t move us toward the long-term goal of drought resilience. That requires strategic investments in local drought-resilient water supply projects, costs mostly borne at the local level.
The state recently took a step in the right direction by approving $3.5 billion in budgeted funds for water projects, but the details of how that money will be used are still being worked out. It is important that funds are directed to local drought-resilience projects. That would go a long way toward accelerating the 21st-century water solutions we need.
Consider our two regions: Sacramento and San Diego. We both have dry summers, but our water supplies are very different.
San Diego’s water comes from locally developed and imported water sources. Sacramento’s supplies come from nearby rivers fed by snowmelt and groundwater. That’s why we’ve chosen to solve our water supply challenges very differently.
Gov. Gavin Newsom called on residents to voluntarily cut back on their water consumption by 15% as California continues to face unseasonably high summer temperatures. Plus, more than a year into the COVID-19 crisis, seven million tenants across the country are behind on rent and many small landlords are struggling to pay their bills as well. And this weekend in the arts: the culmination of a pandemic-era program from the city’s Commission for Arts and Culture, live performances of a haunting dance production, an outdoor music, art and food festival in Oceanside and it’s the closing weekend of a very timely virtual play.
Gov. Gavin Newsom’s call for all Californians to reduce their water use by 15 percent amid a severe drought across most of the state won’t be met with the same urgency in San Diego County as elsewhere because of a decades-old effort to diversify water supplies here and because of a new court order.
Last month, the U.S. Supreme Court unanimously declined a legal challenge by Imperial Valley farmers that had the potential to threaten the San Diego County Water Authority’s access to Colorado River supplies. This is why San Diego County is being asked to conserve but is not one of 50 counties in the state subject to Newsom’s stricter drought decrees.
El Cajon homeowner Christine Laframboise’s water-saving landscape design trading turf for a less thirsty approach was named the Otay Water District’s 2021 WaterSmart Landscape Contest winner.
The annual contest is held by water agencies throughout San Diego County to award one resident from their respective service area for their water-saving landscape. Otay selected Laframboise for her well-thought-out design, plant selection, maintenance, and methods for efficient irrigation.

Equipped with a new landscape plan, Laframboise enlisted the help of her husband and son to remove all the grass responsibly. She installed water-wise features such as mulch, stone, and low-water-use plants.
Her landscape now includes a drip-irrigation system, rotating nozzles, and a smart irrigation controller to schedule efficient water use. The El Cajon homeowner decreased her overall water use by an average of 42%. She waters only two or three times a week and especially enjoys the pollinators attracted to her new yard. She can maintain it on her own and no longer needs a lawnmower.
Laframboise’s project qualified for a $2,140 rebate from the Water Authority’s WaterSmart Turf Replacement Program.

“My yard evolves as I learn more about different plants and where I live locally. I recently replaced dyed wood chips for shredded redwood bark. It is safer for pets, children, and wildlife,” said Laframboise. “I also plan to add more natives to attract more wildlife and further reduce my water use.”
The Otay Water District Board of Directors recognized Laframboise at its July 7 meeting with a certificate, a gift certificate to a local nursery of her choice, an “Award-Winner” yard sign to display, and other promotional items.
(Editor’s note: The Otay Water District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
