Pasadena Water and Power
GLENARM POWER PLANT
REPOWERING PROJECT WORKSHOP
Pasadena City Council
February 4, 2013
Item 13
Glenarm Repowering Project
Pasadena Water and Power
• Build a new combined cycle electric generation unit (68 MW net, 71 MW gross)
• Decommission existing B3 electric generation unit (65 MW net, 71 MW gross)
• Close State Street cul-de-sac off of Fair Oaks Avenue
• Construct control room, instrument shop and offices
• Modify existing Pump Building as Maintenance shop

Why Repower ?
Pasadena Water and Power
City’s Electrical System Must Stay Reliable
• Need dependable local generation to back up single energy import location
• B3 can’t be depended on for too long …47 years old, spare parts problems
• Other alternatives (i.e. another import connection) not feasible
• Reduced operations cost
• New efficient unit is necessary to reduce dependence on coal
• Flexible generation with quick start enables wind and solar power integration
• Approximately same cost over 20 years to maintain B3 vs. new unit
The City Council approved 2009 Energy IRP on 3/16/2009
•
Replace existing B3 unit with equivalent size combined cycle unit by 2015

CEQA / EIR- Major Focus Areas
Pasadena Water and Power
• Significantly high greenhouse gas emissions
CEQA compares emissions from new unit operating entire year at full capacity with
B3’s actual recent operation i.e. 4% of full capacity
On MWh basis new unit emits ≈30% less
•

•
Exemption for height of structures…125 ft. stack
Cultural Resources – Historical resources (Glenarm Building)
Land Use and Planning – Consistency with South Fair Oaks Specific Plan
Noise – Noise Element of General Plan & Noise Ordinance
Project Labor Agreement…. Discussion with CURE underway, emphasis on local
hiring and apprenticeship
Substantial comments received on draft EIR

•
•
$100 million of tax exempt revenue bonds
Estimated pricing date June 1, 2013
30 year, level debt service, estimated 4.0% true interest cost
Annual debt service approximately $7 million
$100 Million Tax-Exempt Financing
Aggregate Debt Service
$25
($Millions)
$20
$15
$10
$5
$0
Existing Debt Service
•
Series 2013
Impact of additional debt service may be reduced by offsetting revenues from ancillary
services, wholesale energy transactions and reduced operating expenses due to
increased efficiencies
