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

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.

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.

Water Authority Wins Four Awards for Outstanding Projects

/in , /by

The American Public Works Association and American Society of Civil Engineers recently presented the San Diego County Water Authority with four awards for construction projects that exemplified outstanding skill, dedication and collaboration from staff in many departments. All of the projects were underway or completed during the COVID-19 pandemic, and project teams navigated shutdowns, adapted to health and safety restrictions, and overcame many other uncertainties – in addition to typical challenges encountered during construction projects.

1) APWA Project of the Year: Northern First Aqueduct Structures and Lining Rehabilitation

With extensive coordination between the Water Authority’s Asset Management, Operations, Maintenance, Right of Way, Water Resources, Engineering and Public Affairs teams, the First Aqueduct rehabilitation project was completed in early 2021. Significant work had not been performed on the First Aqueduct since the completion of Pipeline 1 in 1947 and Pipeline 2 in 1954. The Operations and Maintenance Teams worked closely with multiple member agencies to ensure no impacts to water deliveries over the extended shutdowns required to reline both Pipelines. These extended shutdowns allowed the Asset Management team to inspect 27 miles of pipeline along the aqueduct using innovative technologies – the first time this had been done in nearly 75 years.

“Since the project included more than 35 work sites spread out over 15 miles, many in rural areas of the county, we collaborated closely between different departments and member agencies to ensure that water service was not disrupted,” said Emma Ward-McNally, Water Authority engineer.

2) APWA Honor Award: Vallecitos 11/Vista Irrigation 12 Flow Control Facility

This new facility replaced the existing Vallecitos 2/Vista Irrigation 1 facility that was built in 1954. The Water Authority’s Operations and Maintenance team worked closely with the Engineering team to develop a construction sequence to build the new facility while maintaining water service to member agencies.

“A meticulous level of detail in the design process allowed for the project to be completed with minimal changes during construction,” said Jim Zhou, Water Authority senior engineer.

3) APWA Honor Award: San Diego 28 Flow Control Facility

The new flow control facility replaced the San Diego 12 flow control facility. The Water Authority’s Right of Way team worked closely with the City of San Diego to acquire property rights for the facility. During construction, electrical and rotating technicians from Operations and Maintenance provided support to ensure that the facility was constructed correctly and that electrical relay protection was coordinated when connecting to San Diego Gas & Electric.

“The new facility repurposed an existing building at the site, but it was forward-looking – the project included the installation of a second pipe train for a future inline hydroelectric turbine,” said Aaron Trimm, Water Authority senior engineer.

4) ASCE Award of Excellence: Pipeline 5 Emergency Repair

After nearby Pipeline 4 was repaired in late 2019, the Asset Management team inspected Pipeline 5 in early 2020, and found it needed repairs as well. Multiple Water Authority departments and teams collaborated to launch the emergency repairs on Pipeline 5, despite the uncertainty of the growing pandemic. The Engineering Contracts group executed five contracts and task authorizations for design, construction and inspection within a few weeks to make the project happen, and the work was completed in April 2020.

“The project was a true team effort that required collaboration from multiple departments to ensure that the emergency repair could be completed even as the region was shutting down due to the pandemic,” said Colin Kemper, Water Authority senior engineer.

Water Usage Down Sharply in San Diego, Shrinking City’s Reliance on Expensive Imported Supplies

/in , , /by /The San Diego Union-Tribuneby David Garrick Mentioned: San Diego County Water Authority

San Diego’s vulnerability to water shortages and drought is shrinking significantly because residents and businesses are using less water and city officials are boosting the local supply.

A new city analysis shows local water use dropped sharply from 81.5 billion gallons in 2007 to about 57 billion gallons in 2020, even though the city’s population has grown about 1 percent per year over that time.
