San Vicente Energy Storage Facility Powers Ahead with $18M Boost

/in , /by

July 16, 2021 – 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

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.

Energy for 135,000 households

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.

Construction jobs

“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.”

Environmental reviews, licensing

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.”

Pumped energy storage

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.

Energy Storage Process-San Vicente-Pumped Hydro-Energy

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.

Free fall. That’s how people are describing California’s economy as the coronavirus ravages on.

Virtually overnight, one in five Californian’s became – and unfortunately remain – unemployed. In Los Angeles, the unemployment rate is tracking with the peak of the Great Depression. In other parts of the state, the jobless rate is projected to climb as high as 40%. As former Gov. Gray Davis said about today’s challenges, “There’s no playbook. There’s no precedent.”

Water suppliers in San Diego County say future COVID-19 federal and state stimulus packages should include funding for shovel-ready projects that would create jobs in the region.

In a letter to members of California’s congressional delegation, a group of 13 agencies, including the San Diego County Water Authority and 10 of its member agencies, and the cities of Del Mar, Oceanside and Poway, say the region’s water utilities have dozens of infrastructure projects that could be launched with an infusion of state and federal stimulus funding.

Stimulus Funds Would Create Regional Jobs, Enhance Water Reliability

/in , /by

Water suppliers in San Diego County say future COVID-19 federal and state stimulus packages should include funding for shovel-ready projects that would create jobs in the region.

In a letter to members of California’s congressional delegation, a group of 13 agencies, including the San Diego County Water Authority and 10 of its member agencies, and the cities of Del Mar, Oceanside and Poway, say the region’s water utilities have dozens of infrastructure projects that could be launched with an infusion of state and federal stimulus funding.

“As the water suppliers throughout San Diego County, across the state, and around the nation are confronting the unprecedented impacts of the COVID-19 pandemic, there are several actions that the federal government could take to provide some much-needed relief,” according to the letter dated May 31.

From replacing valves in pipelines to building water purification facilities, to developing a major pumped hydropower energy storage project for the region, the funding boost would advance efforts to enhance water reliability and increase jobs across San Diego County.

Financial stress, economic fallout from pandemic

The letter requests the following action items be supported as Congress discusses additional legislative relief packages:

  • Allow for use of federal funds to backfill for lost revenue: The largest issues that water suppliers are currently facing are the immediate budgetary impacts and the ongoing effects of lost revenues. Allowing water systems to use federal funds to fill the gap being created by lost revenue would provide significant assistance to prevent layoffs or furloughs, minimize project deferrals or delays, and help avoid other associated impacts that may have a lingering negative effect on regional economies. An analysis produced last month by the Association of American Metropolitan Water Agencies and the American Water Works Association estimated that drinking water utilities throughout the county are facing an annualized revenue loss of approximately $13.9 billion as a result of the pandemic – a sum equal to nearly 17% of the sector’s annual revenue.  We strongly encourage Congress to set aside robust funding for water utilities to help offset these fiscal losses. Otherwise, ratepayers will face escalating costs and reduced economic activity related to delayed capital investments, which will only further hinder the nation’s, state’s, and region’s economic recovery. 
  • Extend the Emergency Payroll Tax Credit to Public Entities: The “Families First Coronavirus Response Act” required public employers to provide paid sick and family leave, yet the law excludes these same employers from receiving payroll tax credits made available to private employers. Extending this tax credit to local governments would help cover the costs associated with these programs.
  • Restore advance refunding for tax-exempt bonds: This action would allow flexibility for local government entities to access billions of dollars to reallocate and spend on other projects and priorities, which would be much needed during this time.
  • Aid to low-income ratepayers: COVID-19 response legislation should also include a separate component to ensure that low-income customers are able to afford to keep up with their utility bills throughout the pandemic. Without federal assistance targeted at these customers, some low-income households will fall even further behind on their bills, making it that much more difficult for them to catch up with their payments once the crisis ends.

San Vicente Energy Storage Facility

Pumped Energy Storage-WNN-June 2020-graphic

Pumped energy storage facilities are part of an integrated and sustainable energy system that includes the production, storage and distribution of clean energy.

Regional energy project needs regulatory path

One of those shovel-ready projects does not require any state investment or financial assistance to generate economic stimulus. But it needs a regulatory path forward, which could come in the form of state legislation or decisions by the California Public Utilities Commission.

The Water Authority and the City of San Diego have been working on the San Vicente Energy Storage Facility project for several years. All equity and debt financing would be provided by a private investor.

Generating renewable energy and jobs

The project would create a small upper reservoir above the existing San Vicente Reservoir, along with a tunnel system and an underground powerhouse to connect the two water bodies. The powerhouse would contain up to 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 energy. During peak energy use, the system would create clean energy as water from the upper reservoir flows downhill through the turbines.

“Our developer estimates the project could generate more than 50,000 hours of preconstruction work, followed by more than 1,000 jobs during a four-year construction period,” said Gary Bousquet, with the San Diego County Water Authority. “When it’s completed, the facility could store huge volumes of renewable energy and then use that energy when renewables are not available, such as nighttime.”

Bousquet said the project, when completed, would also generate additional revenue to offset water agency costs and help stabilize water rates.
