Lake Elsinore Advanced Pump Storage (LEAPS)and Talega-Escondido / Valley-Serrano(TE/VS)Transmission Line Project

Presentation to the San Jacinto Watershed Council October 7, 2004

pump storage project description
Pump Storage Project Description
  • Nominal 500 MW power project utilizing pump turbine machines
  • Upper reservoir in Morrell Canyon of the Cleveland National Forest
  • Lake Elsinore to be the lower reservoir with penstock tunnels for inlet/outfall
  • Power plant ~ 240 ft below the surface of Lake Elsinore
  • Advanced pump storage plant:
    • Pump lower reservoir water to upper reservoir during off peak energy periods
    • Return water through the turbines and generate power during peak energy periods
  • Will be one of the most efficient pump storage plants in the world

Morrell Canyon

talega escondido valley serrano transmission line project description
Talega-Escondido / Valley-Serrano Transmission Line Project Description
  • 28.5 mile 500 kV transmission line
  • 1,600 MW design capacity
  • Most of the line runs through National Forest land
  • Application for line accepted by the US Forest Service
  • Language in current Energy Bill in Congress directs USFS and BLM to facilitate routing
  • USFS has agreed to work with FERC to permit both projects under FERC direction
  • This is the wires and non–wires solution to one of the most congested region in California
lake elsinore facts
Lake Elsinore Facts
  • Largest natural lake in Southern California  3,000 surface acres
  • Located 80 miles to Los Angeles & 40 miles to San Diego
  • State transferred ownership of lake to the City in 1993
  • Project to improve inflow and outflow and lake health
  • Water improvement works completed in 1995:
    • Freshwater wells
    • 17,800 ft. earthen levee
    • 350 acres of wetland habitant
lake management history
Lake Management History
  • Until 1995, Lake Elsinore is part of California Park System. The State attempts to offset the Lake’s evaporation losses and control flooding for several decades with little or no success
  • In 1988 Lake Elsinore Management Authority (LEMA) was created to design a project to maintain lake levels and prevent future flooding
  • In 1993, a Bureau of Reclamation Loan of $26 million and local contributions of $13 million LEMA constructed the Lake Management project
  • 1995 State deeded the Lake over to EVMWD and the land under the Lake to the City of Lake Elsinore
  • 2000 State Proposition 13 passes creating the Lake Elsinore San Jacinto Watershed Authority (LESJWA) and appropriating $15 million for watershed cleanup in the Lake Elsinore San Jacinto Watershed
leaps project history
LEAPS Project History
  • Elsinore Valley Municipal Water District “District” applied to FERC 3/92
  • Application was pre-empted by adjoining cities of Anaheim, Azusa, Banning, Colton & Riverside
    • Agreement that District develop project
  • The Hydro Company agreed to develop project for District in 1997
  • Enron North America was briefly involved, but no agreements were ever signed
    • Following a company directive to no longer develop assets and stating a lack of resources, they withdrew in March, 2001.
  • Supported by local Federal and State representatives
technology equipment
  • 2-Voith Siemens pump turbines
  • Each unit will pump water or generate power
  • When coupled with a 337,500 HP generator, each pump turbine produces 250 MW
  • 2 - Penstocks, each 18 ft. diameter
  • Power plant:
    • Total head at turbines » 1640 ft.
    • Lake will fluctuate 18” max. (over 16 hour period)
  • Water system flow:
    • Head Lake, Morrell is at 2,880 ft. elevation and will hold » 5,500 acre feet
    • Lower reservoir, Lake Elsinore at 1,240 ft. elevation, contains » 68,000 acre feet

Turbine Wheel

easy leaps performance facts
Easy LEAPS Performance Facts
  • 83.3% wire–to–wire efficiency for electricity storage
  • Pump for 1 hour (@ 600 MW) allows generation for 1 hour (@ 500 MW)
  • Daily maximums:
    • Generation: 12 hours at 500 MW
    • Storage: 12 hours at 600 MW
    • Nominal Storage: 6,000 MW Hours
  • Fully dispatchable in 15 seconds
  • Can operate for up to 18 continuous hours in emergency
  • Lake will fluxuate  6 inches to a maximum 18 inches
costs to evmwd for maintaining lake elsinore
Costs to EVMWD for Maintaining Lake Elsinore
  • Current projects
    • $15 million from LESJWA
  • Future projects
    • Initial capital from $11 million to $22 million
    • Annual operating costs from $2 million to $5 million
    • Costs depend on standards set by the Regional Water Quality Control Board
  • LEAPS is designed to substantially offset future expenses for Lake Management and provide a stable lake level
permitting history
Permitting History
  • 9/15/00 - Submitted preliminary application to FERC
  • 12/01/00 - Selected equipment supplier
  • 2/21/01 - FERC issued preliminary permit PN11858-000
  • 4/23/01 - Initial consultation package to all agencies
  • 6/12/01 - Joint public meeting @ EVMVD
  • 9/09/03 - Draft FERC application distributed to 140 agencies and interested parties
  • 2/2/2004 - License Application filed with FERC
  • 9/9/2004 - FERC environmental scoping meetings @ EVMWD Headquarters
licensing schedule
Licensing Schedule*

If Federal Energy Bill passes, requires decision on transmission corridor (at least) in 1 year max

FERC license application submitted February 2004


FERC anticipates 6-12 months to receive FERC license and joint state environmental permits (USFS Cooperating Agency)

Permits for Line and LEAPS may be issued concurrently or not

Optimally, line operational around early-2007 Leaps Unit 1 on line late-2007 Leaps Unit 2 on line late-2008
