100 Billion Gallons-Carlsbad Desalination Plant-Water Supply

Carlsbad Desalination Plant Celebrates 100 Billion Gallons Served

The Claude “Bud” Lewis Carlsbad Desalination Plant has served more than 100 billion gallons of high-quality, locally controlled water over the past seven years – a milestone passed in late October, as California entered a fourth consecutive year of severe drought.

The plant produces an average of more than 50 million gallons of high-quality, locally controlled water every day. It’s a foundational water supply for the San Diego region that minimizes vulnerability to drought and other water supply emergencies. The facility is the largest, most technologically advanced and energy-efficient desalination plant in the nation, and it has provided a sustainable water supply to residents and businesses in San Diego County since December 2015.

Core water resource

“As we mark this achievement, water from the seawater desalination plant continues to reduce our dependence on imported water sources, which has the effect of making more water available for drought-stricken communities elsewhere,” said Mel Katz, Board chair for the San Diego County Water Authority. “Since coming online in 2015, the Carlsbad Desalination Plant has met nearly 10% of the region’s water demand, and it will be a core water resource for decades to come.”

“Reaching 100 billion gallons demonstrates the value, effectiveness, and reliability of the desalination plant, as it produces high-quality water to help meet the needs of the region’s residents and businesses,” said Channelside President, Sachin Chawla.

The desalination plant is a key piece of the region’s multi-decade strategy to diversify its water supply portfolio. A 30-year Water Purchase Agreement between Poseidon (Channelside) LP and the Water Authority allows for the production of up to 56,000 acre-feet of water per year, enough to meet the needs of approximately 400,000 people.

Reverse osmosis is the heart of the Carlsbad Desalination Plant. During this process, dissolved salt and other minerals are separated from the water, making it fit for consumption. This reverse osmosis building contains more than 2,000 pressure vessels housing more than 16,000 reverse osmosis membranes. Photo: San Diego County Water Authority

Reverse osmosis technology

Desalination uses reverse osmosis technology to remove water molecules from seawater. Water from the ocean is forced through tightly-wrapped, semipermeable membranes under very high pressure. The membranes allow the smaller water molecules to pass through, leaving salt and other impurities to be discharged from the facility.

Carlsbad Desalination Plant Hits Milestone 100 Billion Gallons Served

The Claude “Bud” Lewis Carlsbad Desalination Plant has served more than 100 billion gallons of water over the past seven years — a milestone reached in late October, the San Diego County Water Authority and plant owners announced Tuesday.

The plant, which produces 50 million gallons of drinking water daily, enough for 400,000 homes meeting 10% of San Diego County’s water demand, is the largest in the United States.

Poseidon, U.S. Fish & Wildlife Launch Wetlands Restoration in South Bay

Partners in a plan to restore 125 acres of degraded coastal wetlands as a mitigation project for the Carlsbad seawater desalination plant celebrated the start of construction Friday morning in Imperial Beach.

The Otay River Estuary Restoration Project in South San Diego Bay is a joint effort by the desalination plant operator Poseidon Resources, the U.S. Fish and Wildlife Service and other agencies to improve the habitat for native fish, plants and birds, particularly migratory shorebirds and other salt marsh-dependent species.

Carlsbad Desalination Plant Cuts Energy Demand to Help Avoid Blackouts

Poseidon Resources (Channelside) LP and the San Diego County Water Authority are temporarily reducing water production at the Claude “Bud” Lewis Carlsbad Desalination Plant to support statewide emergency energy conservation efforts during the extreme heat wave.

While the plant accounts for less than 1% of peak energy demand in San Diego Gas & Electric’s service territory, Channelside and the Water Authority are committed to supporting electrical reliability while ensuring continued delivery of safe and reliable water supplies. The partners reduced water production at the plant by about 20% for three days over the Labor day holiday weekend. Regular water deliveries were made from other sources. The reduced production helps decrease energy demand during the statewide emergency.

“The partnership by the Water Authority and Channelside is another reminder of the value our investments in cutting-edge technology and water supply reliability,” said Sandra L. Kerl, general manager of the Water Authority.  “Desal plant operations are nimble, so production can be ramped up and down in response to local needs. This flexibility underscores the value of regional water supply planning, which allows us to activate solutions during challenging times.”

The Carlsbad Desalination Plant is the largest, most technologically advanced and energy-efficient desalination plant in the nation. The plant has produced more than 90 billion gallons of drinking water for San Diego County since operations began in December 2015. Starting Sunday, Sept. 4, the plant ramped down operations, making an additional 9 megawatts of power available for other uses.

Pumped energy storage

In addition, the Water Authority and the City of San Diego are collaboratively advancing the proposed San Vicente Energy Storage Facility in East County, one of the most promising pumped energy storage solutions in California. Pumped energy storage projects are designed to store excess renewable energy from solar and wind during the day, and then discharge that energy when energy use spikes or renewable energy is not available. As proposed, the project could store 4,000 megawatt-hours per day of energy (500 megawatts of capacity for eight hours), which is enough energy to provide approximately 135,000 homes with power.

Energy reliability, water reliability

The Carlsbad Desalination Plant eliminates the need to transport water from Northern California to the San Diego region, offsetting approximately 190,000 megawatt-hours of electricity and 68,000 tons of carbon emissions each year. The plant also uses energy recovery devices that save an estimated 146 million kilowatt-hours and reduce carbon emissions by 42,000 metric tons every year.

“This is an example of how desalination plants can help contribute to energy reliability, in addition to water reliability, by taking appropriate action to increase the available energy capacity during the extreme heat event,” said Channelside President, Sachin Chawla. “We’re proud to do whatever we can to help our region address the current energy shortage.”

California’s Grid Holds Up Another Night and Avoids Rolling Blackouts Here

California came within a hair’s breadth of experiencing rolling blackouts Tuesday night, but the system operator that manages the grid for about 80% of the Golden State continued to keep the lights on.

The California Independent System Operator at 5:17 p.m. issued a stage 3 Energy Emergency Alert, a measure that warns energy users that rotating outages may be imminent due to sustained electricity demand eating into reserve margins.

State Warns of Possible Rolling Blackouts Amid Scorching Heat Wave

The operator of the state’s power grid warned residents Tuesday to prepare for possible rolling blackouts, as a drawn-out heat wave reaches its peak and drives electricity demand to an anticipated record level.

 

VIDEO: The heat wave is stretching into the seventh day and relief is not expected anytime soon which means the demand for energy is straining the grid. The California Independent System Operator has issued a Flex Alert asking residents to conserve energy during peak use but as KPBS reporter Alexander Nguyen shows us it is also tapping other sources for energy.

A Salty Dispute: California Coastal Commission Unanimously Rejects Desalination Plant

The California Coastal Commission tonight rejected the proposed construction of a desalination plant in Huntington Beach, sealing the controversial project’s fate after more than 20 years of debate.

The unanimous decision about the $1.4-billion plant in Huntington Beach is pivotal because it sets a high bar for the future of turning seawater into drinking water in California, which can help buffer its vulnerable water supply against drought.
