2. Hydropower’s staying power
Hydropower is among the most reliable forms of renewable energy, and while capacity has remained constant, innovations suggest we could tap more resources in the coming years.
What’s clear: Currently, we have about 102 GW of hydropower and pumped storage capacity, or enough to power more than 75 million homes in the United States. DOE’s HydroVision predicts the U.S. could add 50 GW of hydropower through 2050, including:
- 4.8 GW in retrofitting existing dams for hydropower
- 6.3 GW in upgrades on existing hydropower
- 35.5 GW of pumped storage hydropower
Plug in: In 2023, Duke Energy will upgrade its Bad Creek Hydro Station in Salem, South Carolina, adding 280 megawatts by implementing advancements in hydraulic design to increase the capacity of existing units without building new dams, reservoirs, or powerhouses.
