Hydropower’s Role in the Electricity Grid
Hydropower plays a vital role in the electricity grid as the largest source of clean, renewable electricity in the United States. Accounting for approximately 7% of the nation’s total electricity generation, hydropower contributes significantly to the country’s clean energy goals. Through its reliance on the natural power of running water, hydropower generation minimizes greenhouse gas emissions and reduces dependence on fossil fuels.
Existing hydropower facilities utilize the electricity grid to distribute clean energy to homes, businesses, and industries across the nation. This integration helps to meet the increasing demand for electricity while reducing the environmental impact associated with traditional power sources.
One key aspect of hydropower’s role in the electricity grid is its ability to offer flexibility and reliability through pumped-storage hydropower. This technology allows excess electricity generated during times of low demand to be used to pump water uphill to a reservoir. When demand for electricity is high, water is released from the reservoir, flowing downhill and driving turbines to generate electricity. This stored energy can be quickly and efficiently released to meet peak demand, stabilizing the grid and ensuring a reliable supply of electricity.
The U.S. Department of Energy’s Hydropower Vision report outlines the potential growth of hydropower in the coming years. The report projects an increase in hydropower generating and storage capacity from 101 GW in 2015 to nearly 150 GW by 2050. This growth is essential for meeting the country’s clean energy goals and ensuring a sustainable future.
To provide a better understanding, the table below highlights the current hydropower generation capacity in the United States:
| Renewable Energy Source | Installed Capacity (GW) |
