The San Vicente reservoir in San Diego County stores water from as far away as the Colorado River. Pumping water into a smaller reservoir in the surrounding mountains could store excess solar power until it's needed, when the sun sets.The San Vicente reservoir in San Diego County stores water from as far away as the Colorado River.

It's a way to store the electricity. When the sun goes down and solar power disappears, operators would open a valve and the force of 8 million tons of water, falling back downhill through those same pipes, would drive turbines capable of generating 500 megawatts of electricity for up to eight hours. That's enough to power 130,000 typical homes.
Yet earlier on that same day, there was so much solar power available that the grid couldn't take it all. Grid operators"curtailed," or turned away, more than 2000 megawatt hours of electricity that solar generators could have delivered, enough to power a small city. That electricity was wasted, and there was no way to store it for later, when grid operators desperately needed it.
tidal dam might work
renewable energy is poopoo
PinkPeonies2014 One word: science.
Finally a solution that doesn't require more pollutants to balance the infrequency of Solar or Wind. Without solutions like this CO2 emissions would rise as places go to Solar over Nuclear.

We still need water! 😬
Shouldnt they finish that train rail before they waste more money on shit that will never happen
What water?
Non-chemical batteries are so cheap it is the best solution. We need this everywhere
Fascinating. Fox News will never tell you that CA had more energy than it could handle because of solar. Once storage gets better thru this or batteries, the last coal plants will die a quick death.
Oldest battery technology but yay San Diego!!
Great solution that should have been much more widely used before now. However, fresh water being more scarce a commodity, especially in the southwestern US, makes this another competitor, so less useful long term.
Not sure if they still do, but Luxembourg earned a tidy sum pumping water uphill at night when it was cheap, and selling it to the industrial Ruhr Valley during the day.
And what happens when we run out of gravity?
Great solution that is already used in Scotland. A battery is anything that can store potential energy. Water batteries are mostly environment friendly, as long as mitigations are in place for fish and other wild life.
Unless you need the water for another purpose.
