Agenda

• Who is Silicon Valley Power?• Energy Efficiency Program value

– To our customers

– To our utility

– To our community

• What we can bring to the table• Case study

– Owens Corning

4

Silicon Valley Power

• City of Santa Clara’s municipal electric utility• Located 50 miles south of San Francisco• System Statistics:

– ~500 MW peak– ~3000 GWh sales (70% load factor)– 90% of sales are commercial and industrial– $0.089 system average rate– Diverse resources throughout Western USA

• 28.5 % eligible renewable resources (Geothermal, wind, small hydro)• 50% including large hydro

5

Type of Customers

• High tech headquarters and R&D– Intel, Sun Micro Systems, Applied Materials, National

Semiconductor, etc.

• Datacenters • Manufacturing

– Solar and semiconductor

– Paperboard mills

– Fiberglass insulation

6

Energy Efficiency Programsare Good for Business

• Helping customers use our product more efficiently– Helps facilities compete and keeps them open

• Retains jobs, load, etc.

– Attracts new business to community• Benefits other customers by spreading fixed costs

– Frees up resources to serve others

– Reduces carbon footprint

• Provides contact with customers– Leads to communications on many issues

7

What our customers want

• Customers’ primary energy concerns– High reliability– Environmental accountability– Stable, competitive prices– Speed to market

8

SVP Industrial Energy Efficiency Programs

• Free Energy Audits – Limited scope due to resources and expertise

• Lighting, HVAC, Motor & VFD Rebates• Customer Directed Rebates• Compressed Air Management Program (CAMP)• Keep Your Cool – Gasket Replacement• Retrocommissioning

9

DOE Save Energy Now Program

• Reduce industrial energy use by 25% over 10 years• Provides technical expertise

– No cost energy assessments

– Focus on energy-intensive systems such as: • Process heating

• Steam

• Pumps

• Fans

• Compressed air

10

Case Study

• Owens Corning – DOE’s “Save Energy Now” program

– SVP’s Compressed Air Management Program

– Multiple energy saving projects identified

11

Owens Corning

12

Owens Corning

• Fiberglass insulation manufacturing facility – Major industrial customer since 1949

– Provides employment and customer diversity

– Plant competes with other manufacturers and other Owens Corning plants

13

DOE Save Energy Now Program (Owens Corning cont’d)

• Participated in Save Energy Now at corporate level• At Santa Clara facility

– Fan Assessments

– Pump Assessment

– Compressed air and Other Assessments

14

Fan Assessments(Owens Corning cont’d)

• DOE Save Energy Now Program– Trained Owens Corning employees to perform

assessments

• In Santa Clara: – 2 fan assessments in 2007

– 1 assessment in 2008

– 2 additional assessments planned

15

Fan Assessments (Owens Corning cont’d)

• 2007 Fan assessments resulted in 3 projects: – VFD to Penclone (M – Line)

• 361,000 kWh savings annually

– VFD to Penclone (O – Line)• 361,000 kWh savings annually

– Oven Fan VFD• 398,000 kWh savings annually

– Projects will be complete in Fall 2008

• Additional Project considered for 2009– Forming Fan Optimization VFD

• Potential savings of 2,296,000 kWh annually

16

Pump Assessment (Owens Corning cont’d)

• Pump Assessment performed in 2007• Resulted in review of treated water flows

– Installation of VFDs

• Project completed in June 2008• Annual savings of 263,000 kWh

17

Compressed Air and Other Assessments

(Owens Corning cont’d)

• Compressed Air– SVP’s Compressed Air Management Program (CAMP)

• Same consultant as DOE Save Energy Now Program

• Compressed Air system improvements– 3,064,000 kWh savings annually

• Project to be complete in Fall 2008

– Process Heat Assessment• DOE PHAST tool was not applicable to the glass industry

18

Owens Corning cont’d• DOE Save Energy Now Program Provided

– Technical expertise and assessments– Training of Owens Corning personnel

• SVP will provide– Over $400,000 in rebates

• SVP and City benefits– Retained a major industrial load

• Diverse from many loads in our territory– Retained jobs
