Drought: Marin Vets Options for Desalination, Water Pipeline

/in , , /by /Marin Independent Journalby Will Houston

Marin Municipal Water District announced Friday that it has found a potential vendor for temporary desalination plants and four Central Valley water suppliers that could transfer water to the county through a pipeline across the Richmond-San Rafael Bridge.

The emergency water projects are being explored based on forecasts that the majority of Marin residents could run out of water by July 2022 if the upcoming winter is as dry as last year’s. The district serves about two-thirds of the county including 191,000 residents in central and southern Marin.

San Vicente Dam-Fill Chute-Energy Storage Project

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

/in , /by

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.

San Diego County is Not Being Asked to Reduce Water Usage. Why?

/in , , /by /KUSI-TVby Logan Byrnes Quoted: San Diego County Water Authority

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.

Opinion: State Should Help Fund Local Water Resilience Projects

/in , , /by /CalMattersby Gary Croucher and Sean Bigley

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.

Bill Aims to Spend Billions to Fix Nation’s Aging Dams

/in , /by /AP Newsby Michael Casey

Lawmakers in Congress on Friday introduced a bill that would pump tens of billions of dollars into fixing and upgrading the country’s dams.

The Twenty-First Century Dams Act, introduced by Democratic U.S. Rep. Annie Kuster of New Hampshire, proposes to spend nearly $26 billion to make the repairs that would enhance safety and increase the power generation capacity of the country’s 90,000 dams. It also calls for removing any dams that have outlived their usefulness.

Opinion: California Isn’t Running Out of Water; it’s Running Out of Cheap Water

/in , , /by /California WaterBlogby Wyatt Arnold

A California water myth which becomes especially pernicious in droughts is that California is “running out of water” (Hanak et al. 2009). Viewing California’s supply and demand pressures in terms of fixed water requirements perpetuates this myth and invariably places undue attention on building additional supply infrastructure. Instead, managing water as a scarce resource suggests a balanced portfolio of water trading, investments in conveyance, smart groundwater replenishment, and demand management. With such a balanced portfolio, 1) California’s water supply situation is not broadly dire, and 2) California’s vast and interconnected water infrastructure and groundwater resources can minimize most problems from the state’s highly variable climate.

Water Authority General Manager Issues Statement on Governor Newsom’s Expanded Drought Proclamation

/in , /by

July 8, 2021 – Sandra L. Kerl, general manager of the San Diego County Water Authority, issued the following statement on today’s expanded drought declaration and proclamation of a state emergency by Gov. Gavin Newsom and his call for Californians to voluntarily reduce water use by 15%:

“While the San Diego region is thankfully drought-safe this summer due to sound planning and decades-long ratepayer investments in new water supplies and storage and adoption of water conservation as a way of life, we must also be part of the statewide movement now underway to address water supply challenges created by drought and climate change in other parts of California.

“The Water Authority strongly supports the governor’s call for the public to voluntarily cutback water use by 15% in order to allow local, regional and state water agencies to plan and take the steps necessary under these changed conditions to maximize the availability of limited water supplies going forward, through the investment of state funding and implementation of other provisions of the Governor’s Proclamation of a State Emergency and Executive Order N-10-21 calling for water conservation.

“The Water Authority will be working closely with our member agencies and with the Metropolitan Water District of Southern California over the next several days, weeks and months, to design and implement strategies to maximize water supply development in collaboration with Governor Newsom and state agencies, in order to protect California.”

Opinion: Water Act Would Keep Water Clean and Affordable

/in , , /by /CalMattersby Alexandra Nagy

California has a long history of treating public water as a commodity instead of a human right and entrusting it to industries that fail to manage it responsibly. Water is a public trust resource that needs protection. The federal Water Affordability, Transparency, Equity and Reliability (WATER) Act would put water systems back in the hands of the people who depend on it for life and livelihood.
