Damn Good Idea: Using a Lake as a Battery

Using the Hoover Dam as a battery by pumping water upstream during the day, thus reducing electricity generation.

I had heard about this idea before, and think it requires further study. The problem is that we cannot easily store electricity. Any electricity generated needs to be used immediately, or we risk blackouts.

California has a lot of wind and solar power generation, but also has hydroelectric power generation from the colossal Hoover Dam. If operated at the same time there might be too much power during the day, when wind and solar contribute, and not enough power at night, when wind and solar do not generate electricity. Excess generated electricity cannot be stored.
