A power plant that uses more power than it generates

Click For Summary
SUMMARY

The Yards Creek Pumped Storage Electric Generating Station is designed to meet peak electricity demands by utilizing off-peak power to pump water from a lower reservoir to an upper reservoir. This facility has a rated electrical capacity of 330,000 kilowatts and operates with reversible pump turbines and motor-generators. Due to energy losses, it requires 3 kilowatt-hours to generate 2 kilowatt-hours, resulting in a storage efficiency of approximately 67%. The economic viability of this system relies on the cost difference between off-peak and on-peak electricity rates.

PREREQUISITES
  • Understanding of pumped storage hydroelectricity
  • Knowledge of electrical generation and peak demand management
  • Familiarity with energy efficiency metrics
  • Basic concepts of reactive energy in electrical systems
NEXT STEPS
  • Research the efficiency of pumped storage systems compared to other energy storage technologies
  • Explore the role of reactive energy in electrical grids
  • Investigate the economic implications of off-peak and on-peak electricity pricing
  • Learn about advancements in capacitor networks for energy storage

They sure are available, not in the power density i previously listed (from MIT), but they sure ARE available..

and you are correct ultracapacitors at this time , make an excellent complement with batteries..
Because they can absorb the energy from regenerative braking , very quickly..Much more quickly than a battery can..
