Water power uses no fuel in the generation of electricity, making for very low operating costs. Duke Energy operates two pumped-storage plants – Jocassee and Bad Creek.
Mt Rawdon Pumped Hydro Energy Storage
Our client and the mine owner collaborated to investigate the site''s potential for a pumped hydro energy storage (PHES) facility. One of the benefits? The opportunity to restore the areas of the mine to a safe, stable, and self-sustaining condition—reducing the environmental impacts of mining and changing the legacy of the site.
Understanding Pumped Hydro Storage as a Renewable Energy
Unlike battery storage, pumped hydro storage uses water as a fluid instead of chemicals and metals, reducing its environmental impact. Hydro plants may last 50 years or longer compared to 8 to 15 years for batteries. Also, pumped hydro storage plants don''t often need their water levels topped up as rainfall usually exceeds evaporation.
