Orange County sees past Poseidon’s efforts to buy support for its desalination boondoggle. Why can’t Gov. Newsom? Poseidon Water, a large water development company, has been pushing to build a $1.4-billion water desalination plant in Huntington Beach. Like Poseidon’s underperforming, high-cost plant in Carlsbad, the plant and its inflated water would be paid for by ratepayers.
One of the most vocal critics of a controversial seawater desalting plant, proposed for the Huntington Beach coastline, will no longer be on the state’s local water board when it votes to approve the project later this year.
Poseidon Water’s long, winding road to building a desalination plant in Huntington Beach could face its biggest obstacle yet if opponents prevail in the upcoming election.
If there were any doubts remaining about whether California is getting hotter and drier, this summer has settled them. We’ve seen record-breaking temperatures and historic wildfires across the state.
The clock is ticking away this week on the reappointment of a key state regional water board member and vocal critic of a controversial, pending proposal for a seawater desalting plant in Huntington Beach.
There are mounting questions over whether Gov. Gavin Newsom will replace William von Blasingame — an Irvine resident first appointed to the regulatory seat in 2013 by former governor Jerry Brown — when his current term expires Sept. 30, ahead of his panel’s vote on the Poseidon Water Co.’s desalination proposal.
The port city of Tianjin is in desperate need of water. The surface and groundwater supplies of this sprawling northeast Chinese metropolis have shrunk to dangerously low levels due to decades of reduced rainfall and overexploitation of the Hai River that flows through the city. According to the Tianjin Environmental Protection Bureau, the city’s per capita water resources are one-twentieth of China’s national average, far below the UN benchmark for a water-stressed region. Despite promoting water conservation and metering among residential and industrial users, Tianjin still faces shortages that drive its reliance on large-scale water-supply infrastructure like the South-North Water Transfer Project and seawater desalination.
In the United States, a similar situation is unfolding. After a prolonged drought between 2011-2015, California’s investment in desalination solutions to supply fresh water to the state’s dry south grew exponentially. While most American desalination plants are used to purify less-saline “brackish water” from rivers and bays, large-scale seawater operations have begun to proliferate in California, as well as Florida and Texas. California alone has 11 municipal seawater desalination plants, with 10 more proposed. Southern California-based Poseidon Water LLC opened America’s largest desalination facility in Carlsbad in 2015, which currently meets about 10 percent of San Diego’s water demand. With the capacity to produce 54 million gallons of water a day, this new desalination plant, as well as another one currently in the works at Huntington Beach, could ensure water security in Southern California.
Along a Huntington Beach coastline dotted with oil rigs and a power plant, one of California’s largest remaining saltwater marshes has been a source of pride for local environmentalists.
But the marsh, known as the Bolsa Chica Wetlands, is endangered despite a years-long struggle to pull together sufficient public funding for its upkeep.
Nearby, the Poseidon Water Co., which has been in a decades-long, controversial fight to build a seawater desalination plant next to the AES energy station at the south end of the city, has justified its project partly with a promise to finance the wetlands’ conservation.
Water agencies across San Diego County are doing their part to stabilize the state’s power grid during this week’s heatwave by generating hydropower and altering operations to trim electricity demands – and they are offering long-term solutions to reduce future energy shortages.
The California Independent System Operator issued a statewide Flex Alert from Sunday through Wednesday, calling for reduced electricity use in the afternoon and evening to limit power outages. Blackouts could affect hundreds of thousands of San Diego County residents, if extreme heat persists.
At Lake Hodges, the Water Authority is running its pumped energy storage facility to meet peak demands. As water flows down the pipeline from Olivenhain Reservoir into Lake Hodges, it generates up to 40 megawatts of energy on demand, helping to manage temporary peak electrical demands or unplanned outages. Then, the water is pumped back to Olivenhain Reservoir when power demands are low to restart the cycle.
In addition, water agencies are taking numerous actions to conserve energy. For the Water Authority, the strategy includes temporarily reducing drinking water production at the Claude “Bud” Lewis Carlsbad Desalination Plant in collaboration with Poseidon Water.
The Carlsbad Desalination Plant is the largest, most technologically advanced and energy-efficient desalination plant in the nation, and it has produced more than 62 billion gallons of drinking water for San Diego County since it began operations in December 2015.
Starting Monday, the plant ramped down operations, making an additional 8 megawatts of power available for other uses. If more load reductions are necessary over the next several days, additional curtailment may be considered at the plant. The power provided by the plant could help offset current energy shortages.
“This partnership by the Water Authority and Poseidon is another reminder of the value of the cutting-edge technology and local control at the Carlsbad plant,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “Operations are flexible and the technology is nimble, so production can be ramped up and down in response to local needs.”
In addition, local and regional water agencies are temporarily shutting down or reducing flows at pump stations and turning off HVAC systems in the afternoons. Some agencies also have the ability to convert to less energy-intensive treatment, for instance, by replacing ozone with chlorine.
Local water agencies also are tapping their significant backup power generation capacity – at their own expense – to ease the strain on the energy grid, following Governor Newsom’s executive order that suspends some regulatory requirements for those units during this emergency event. Local agencies are also looking to work with the administration to ensure that their backup generation capacity can be used proactively to help avoid future energy shortages.
Pumped energy storage facilities are part of an integrated and sustainable energy system that
includes the production, storage and distribution of clean energy.
Beyond the immediate concerns, this week’s heat wave has highlighted the need to increase large-scale energy storage as the state moves toward a goal of 100% renewable energy by 2045. Put simply, the sun doesn’t always shine and the wind doesn’t always blow enough to meet demands, so the state needs more capacity to store peak renewable energy production for peak demand periods.
The Water Authority has proposed building a large-scale pumped storage project at the San Vicente Reservoir near Lakeside. Pumped energy storage projects are designed to store excess renewable energy from solar and wind when it’s available, and then discharge that energy when energy demands increase and renewable energy is scarce.
A 2019 white paper highlighted the importance of pumped energy storage to California’s future.
“Our current situation is the direct result insufficient planning; the state clearly needs additional energy storage now and will need much more in the future,” said Gary Bousquet, energy program manager for the Water Authority. “Environmentally friendly pumped storage projects should be started immediately to address this shortfall, or power reliability will get significantly worse. The San Vicente project can be started now at no cost to taxpayers – users only pay when the project comes online.”
Carlsbad, Calif. (August 18, 2020) –To support statewide emergency energy conservation efforts, Poseidon Water and the San Diego County Water Authority are temporarily reducing water production at the Claude “Bud” Lewis Carlsbad Desalination Plant.
While the plant uses less than 1% of peak energy demand in San Diego Gas & Electric’s service territory, Poseidon and the Water Authority are committed to supporting electrical reliability while ensuring continued delivery of safe and reliable water supplies.
After years of bureaucratic hurdles and increasing regulatory requirements, Poseidon Water was dealt yet another delay Friday, Aug. 7, in its pursuit of a controversial desalination plant in Huntington Beach. The Regional Water Quality Control Board concluded three days of hearings on the project’s next permit by telling Poseidon it must return with a more robust, more detailed mitigation plan to offset the environmental damage the project will cause.
