LADWP RPS Master Plan

On December 13, 2005 LADWP management presented to the Board on how
LADWP plan to meet the RPS goal of 20% by 2010

Six general areas that make up the Master Plan

–
Existing resources – Consisting of Aqueduct, Hyperion digestion, Lopez
microturbines, solar rooftops, landfill gas contracts, Wyoming Wind project, and
purchases
–
Planned resources – Consisting of Pine Tree Wind Project, Powerex Small
Hydro, and the ongoing solar rooftops program
–
2004 LADWP RFP – Resource acquisition consisting of originally seven projects
–
2005 SCPPA RFP – Resource acquisition consisting of originally seven projects
and now new 2006 SCPPA RFP that closes October 16th.
–
LADWP Development – Resource development on LADWP owned properties.
–
Transmission Developments – Consisting of the Pine Tree Transmission Line,
new Tehachapi Transmission System, Green Path Project, and Southern
Transmission System upgrade
DSM Assumptions – Use the Maximum Achievable Level

Planned and Developed Renewable Resources

Pine Tree Wind Project (120 MW)
–
Completed draft RFP specification for BOP work.
–
A final draft RFP specification for design build of the 230 kV transmission line is
complete.
–
Barren Ridge switching station under construction.

Waste to Energy Conversion – Proposed four 25 MW (total of 100 MW) Municipal
Solid Waste to energy conversion technology developments with Los Angeles Bureau
of Sanitation. The projects will be located in Los Angeles and the in-service dates are
projects to be 2010 through 2013.

Concentrated Solar Power – Proposing two 125 MW CSPs for development by
LADWP on owned lands with transmission access and tentative in-service dates of
2010.

Geothermal – 50+ MW of geothermal development in the Salton Sea area on owned
land with tentative in-service date of 2012.
