Approval 1,200 MW
Proposed Alternative
Repowering 840 MW
1,800 MW (1202 MW) 600 MW

• Proposal reduces overall GHG by ~83%
• LADWP > 500% increase in transmission for renewables
Today’s Consideration
2015 Board and Council Approved IPP Contracts
All 36 Participants Approved – Binding Contract
Contract allows “Alternate Repowering” (AR)
AR is NOT a Contract Amendment
AR is NOT a new contract to “buy” a plant
Requires a 35 Participant Vote
Board approval required before LADWP staff can vote yes on AR reduction from
1200MW to 840MW.

Reduction saves ~$400 million
Key Points
This is NOT a New Contract
LADWP is NOT buying a new gas plant
Proposing to Reduce the approved 1200 MW gas plant to AR of 840 MW
360 MW - more transmission for renewables
LADWP - Five fold increase in transmission for renewables
~$400 million project savings
Not approved—project remains at 1200 MW
What is our “Ask”?
Permission from the Board to vote at the IPP
Coordinating Committee to reduce the size of the
IPP repowering from 1,200 MW to 840 MW
A “No” vote results in ~$400 M higher costs and the
construction of 1,200 MW gas plant approved in
2015
