San Diego Proposes Water Batteries to Power 135,000 Homes

The San Diego Water Authority wants to light up the city even when the Sun goes down. The plan is to use San Vincent Reservoir to store solar power energy in what is known as water batteries to optimize the city’s potential for renewable energy.

California cities experience warm days in surplus, which tends to provide abundant renewable resources. The recommended project could store 4,000 megawatt-hours of energy each day, which can power 135,000 homes after the Sun drops. The San Diego Water Authority would undoubtedly develop a smaller-sized top reservoir just above the existing San Vicente Storage tank to make this possible. These would certainly be connected by a tunnel system and a below-ground giant. 

The water authority is preparing to use the San Vicente Storage tank to store solar energy in water batteries. The suggested strategy can store 4,000 megawatt-hours of power daily, which might power 135,000 residences. 

The plan would include the San Diego Water Authority creating a smaller top reservoir above the San Vicente Tank linked by a passage system and a below-ground powerhouse. 

According to the San Diego Area Water Authority’s website, wind and solar facilities supplies go beyond demand during the off-peak periods when power is inexpensive and sustainable. The turbines will then pump water to the upper reservoir, acting as a battery of stored potential power. 

When there was high power usage, the system would undoubtedly discharge power stored in the water back down through turbines. So the exchange is a shut loop, so that water will not be consumed while putting energy into the local grid.

Such systems are also called pumped storage hydropower, which is already in operation around the globe. Although it can take a while before this details plan is accepted and applied, it will be a significant landmark once it is.

These power storage initiatives may be eligible for the same 30% tax credit as solar and wind projects, which would encourage investment in more of these projects. Numerous closed-loop energy storage projects, including one in Oregon, are being considered right now. According to the Swan Lake Energy Storage Project’s website, that may be finished by 2040 and provide power for around 125,000 houses in the Pacific Northwest.

Officials in California are struggling to fix the state’s overloaded infrastructure. State residents risk blackouts because of the extreme heat and a historic drought. As a result of the extreme heat and dry conditions, the ability of big water reservoirs in California to produce hydroelectric power has been drastically reduced. The Sacramento data centre for Twitter malfunctioned in September due to the extreme heat.

State officials have pushed even harder for renewable energy resources this year. In April, California’s grid briefly worked on 97.6% renewable resources, breaking a previous record. And also since April. The golden state was also the fourth-largest electricity supplier in the nation. So pumped storage space hydropower tasks might not just reduce exhausts for the state but additionally be a safeguard for communities in jeopardy of power blackouts.
