• Climate change is real & action needed

• Mandatory reductions needed

• Flexible ways to reach goals: “harness market forces”

• Recognize cost to inaction

City Light’s carbon reduction path

Conservation: Almost a silver bullet

667 Mayors in US / 28 in WA Support Mayor Nickels’ Climate Protection agreement

Step 1: Conservation: 580,000 tons avoided annually

Step 2: Divest of Centralia coal plant: 611,000 tons eliminated

Step 3: Purchased new renewables (Wind) 230,000 tons avoided annually

Step 4: Purchase Offsets: 200,000 tons annually

Success! 2005 / 2006 Seattle City Carbon Neutral – First and only in US

Wall Street’s Favor: Moody’s improved recommendation for SCL bonds based upon low carbon emission profile

First-mover advantage: Locked in long term wind before west coast mandates = higher costs

Cost effective for customers: Conservation = lowers bills / Offsets cost less than $1 per year for residential customers

• Catalyst for Change: Biofuels / Port Electrification

SURE! If all utilities reduced carbon emissions 10% (proxy for City Light’s program) CO2 would be reduced 250 million tons

= 46 million cars!

Characteristics of NW Power

• WA Over 70% hydro

• Large Role of Public Power & BPA

• Conservation achieved 40% load growth

• Major investments in new renewables

• Diminished reliance on coal

• “Coal generation has diminished in utility IRPs to the point where only one utility has a coal plant in its plan.” - IRP Status Memo, Michael Schilmoeller, Power Division, NW Power and Conservation Council, July 31, 2007

• I 937 & HB 6001 along w/ similar standards in CA & OR, favor renewables, conservation & natural gas over coal

• Allocation Matters! Historic Emissions penalize the NW more than any region in US

• R&D money must focus equally on non coal technologies to better fit NW planning

• Encourage (or don’t penalize) conservation

• When CA Sneezes, NW catches cold

• Hydro most vulnerable power system from unchecked climate change

• Wall Street beginning to see financial value of utilities w/ low carbon emissions

• Time for mandatory action & regulatory certainty
