Hydropower is reliable

Remember the sweeping North East blackout in 2003? What could have been a manageable local event tuned into a massive grid stressor that effected more than 45 million people in eight states of the United States. What you may not have known is that hydropower plants in western New York were able to restart quickly and help stabilize the grid because hydropower is the sole generation type that can resume operations without relying on a kick start from an outside power source. Imagine how much more resilient and secure the nation’s power grid could be if more hydropower was added to the mix!

Hydropower functions like a battery

Pumped-storage hydropower (PSH) is the largest form of utility-scale electricity storage in the USA. PSH works like a big battery and effectively safeguards our nation’s energy supply by pumping water between lower and higher-elevated reservoirs. During periods of high electrical demand, water is released from the uppeservoir and rushes to its starting point.

Hydropower is flexible

Hydropower is an extremely flexible resource. It can supply electricity or store it to meet real-time energy needs. In short, hydropower is the ultimate grid stabilizer — it quickly delivers power after an outage, addresses peak demands and maintains proper voltage levels and frequency across the grid. How’s that for being flexible?

Hydropower supports the intergration of other energy sources

Because hydropower is flexible and can store energy, it’s complementary to other forms of generation. Traditionally, PSH stored excess electricity from base-load sources such as coal or nuclear. Now, with more form of variable generation like wind a solar coming online, hydropower can make sure power supplies stay constant — even when the sun isn’t shining or the wind isn’t blowing.

By contributing to a diverse energy mix, hydropower mix, hydropower protects our energy independence and reduces America’s reliance on imported fossil fuels.
