summary
Summary
  • Ludington Plant Overview
  • Operational Characteristics
  • Past & Current Use
  • Impacts of increasing wind generation
ludington pumped storage plant1
Ludington Pumped Storage Plant
  • In operation since 1973
  • Jointly owned by Consumers Energy and The Detroit Edison Company
  • Pond is 2.5 miles x 1 mile
  • Six reversible pump – turbines
  • 360 feet from Lake Michigan to full pond level
  • 27 billion gallons H2O
lps key operating parameters
LPS Key Operating Parameters
  • 1872 MW Generating capacity
  • 1960 MW Pumping
  • 15000+ MWh generation storage
  • 70% cycle efficiency
  • Generators quick start & regulation capable
  • Pumps quickly interruptible
historic and current operational uses
Historic and Current Operational Uses
  • Economic alternative to more expensive generation to meet load
    • If value of generation > 1.4 times cost of pumping
  • Ancillary Services & flexible response to operational uncertainties
managing stored energy is important
Managing Stored Energy is Important
  • Predictability of Cost & Value
  • Strategy for economic value, with room for contingencies
potential impacts of increased wind energy
Potential Impacts of Increased Wind Energy
  • Reduced predictability
  • Increased variation in supply-demand balance
    • Other resources required to compensate for longer duration variations (10’s of minutes to hours)
    • Potential for increased need for ramping capacity & intermediate term reserves capacity
storage technologies have a role
Storage Technologies Have a Role
  • For short term replacement and balancing, pumped storage can fill in
    • rapid response for ramping and contingencies
    • economic generation to buy time for longer lead time units to come on line
    • absorb excess generation
additional considerations
Additional Considerations
  • Reliance on accurate wind generation forecasts
    • Storage Management
    • Overall system optimization
  • Optimum storage management changes
    • May require decreasing daily budget of energy available to day ahead market
  • Limits on ability to cycle pumped storage units to compensate for variations.
  • Pump mode startup is limited
