Solar Energy Resource, Cogeneration and Energy Efficiency Program Development

1
Santa Monica Community Energy Independence
Initiative
Approved March, 2006
2
What is the Community Energy Independence
Initiative?

• A City-wide Program that integrates
• Comprehensive energy efficiency
• Optimal solar potential of rooftops
• Distributed generation where appropriate
  (e.g. microturbines, fuel cells)
• Provides greater consumer and City control over
  costs
• Enhances electric reliability
• Reduces greenhouse gas emissions
• Achieves Sustainable City Plan goals
• Potential to create Net-Zero Energy City

3
Solar Potential Analysis Ensure Roof
Compatibility

• Determine roof type (validated with on-site
  survey)

Examples _ Tile _ Asphalt Shingle _ Composite _
Tar and Gravel
4
Solar Potential Roof Area Determination

• Measure dimensions of roof from aerial

400 2,800 3,200 sf
5
Solar Potential Roof Area Determination

• Measure dimensions of roof from aerial
• Estimate shaded portion ()

Solar Study Results

• 24 million sq.ft. total usable roof area for
  solar
• 103 MW capacity potential from solar
  photovoltaics
• 350,000 sq.ft. of solar thermal for pool heating
  and commercial heating needs
• Ability to estimate any buildings solar potential

9
Solar Survey Results

• Interviewed more than 250 property owners
• Considerable support for investing in
  cost-effective, integrated energy systems
• City should fill the role of program facilitator

10
Energy Efficiency Potential
CEII Program Potential

• Overall savings of 38 in electricity
• Overall savings of 34 in gas consumption

Solar Potential

• 103 MW peak electric (69 of total peak) 350,000
  sq.ft. of solar thermal

Distributed Generation

• 41 MW of DG electric capacity w/ heat recovery

11
Citywide Potential for Reduction in Electricity
Peak Generation Need
In this case all electricity is generated
within the city on a net basis, which means we
will still be using natural gas for distributed
generation.
12
Environmental Benefits of CEII

• Greenhouse gas (CO2) reduction
• Smog (NOX) reduction
• Building Quality Improvements
• Reduced need for centralized power plants

Solar Santa Monica

• 2 year Demonstration Project
• 50 residential, commercial, and municipal
  buildings to be equipped with integrated energy
  efficiency measures, solar photovoltaic systems,
  solar thermal, or distributed generation systems
• 900,000 budget

15
Solar Santa Monica

• Launching January 1, 2007!

16
Goal 50 Buildings
35 residences small businesses 10 commercial
buildings 5 municipal buildings

• Key challenge
• Making solar affordable

18

• Key challenge
• Too many decisions for the resident
• I just dont know where to start!

19
Unique program design concept

• Combining energy efficiency
• and solar
• in one cost-effective package

20
The Package approach

• Easier for customer to make decision.
• Allows for negotiated bulk rates.
• Better overall rate of return on energy
  investment.
