energy awareness
Energy Awareness
  • Global demand for all energy sources forecast to grow 57% over next 25 years
  • U.S. demand for all types of energy expected to increase 31% within 25 years
  • By 2030, Asia will use 56% of the world’s energy
  • U.S. electricity demand will grow by at least 40% by 2032.
  • New power generation equal to nearly 300 power plants (1,000MW) will be needed to meet electricity demand by 2030.
  • Currently, 50% of U.S. electrical generation relies on coal (fossil fuel) while 85% of U.S. greenhouse gas emissions result from energy-consuming activities supported by fossil fuels.

california energy efficiency strategic plan 2008
California Energy Efficiency Strategic Plan (2008)

“The goal is for California’s energy to be adequate,

affordable, technologically advanced, and

environmentally-sound…Cost effective energy

efficiency is the resource of first choice for meeting

California’s energy needs. Energy efficiency is the

least cost, most reliable, and most environmentally sensitive

resource, and minimizes our contribution to climate change.”

sce mission
SCE Mission

Comprehensive HVACA vision for an integrated HVAC portfolio driving market transformation

SCE Comprehensive HVAC exists to:

  • support the HVAC goals of the CPUC
  • provide a catalyst for continuous improvement
  • demonstrate fiduciary responsibility to SCE customers
  • Starting with packaged AC equipment
background
Background
  • Among Southern California businesses, HVAC is typically the largest consumer of energy, the single largest contributor to peak demand and the highest operating expense.
  • An optimized HVAC system reduces energy consumption, saves money, and prevents costly system breakdown.
  • Improved HVAC operation is a leading opportunity for improved energy efficiency, reduced peak power demand, and cost savings.
  • CPUC directed implementation new HVAC program amongst IOU’s to support California’s contractors
sce trial overview
SCE Trial Overview
  • Upgrade existing and “to code” Units when premium HVAC equipment cannot be installed
  • Installation of Enhanced Ventilation Measure first opportunity

  • Replacement incentives: $200-$500 per ton
  • Additional Incentives for enhanced technologies
scienergy mesa
SCIenergy MESA

MESA benefits relative to the three alternatives.

  • No debt: the services agreement is an operating expense under current and forthcoming accounting rules.
  • Potential for endowment to invest and earn its targeted returns.
  • No savings guarantee enforcement concerns.
  • Development flexibility: utilize in-house resources, leverage previous investments; vendor neutral, consultant neutral.

evaporcool
EvaporCool

Hot outside air is cooled as it passes through the EZ-Frame, before it reaches the condenser coils.

This allows the system to operate as though it were cooler outside than it actually is.

On recent 100 degree days (73 wet bulb), in a humid Southeastern U.S. climate, the leaving air temperature of the EvaporCool system entering the condenser is 79.2 degrees!

79.2°F

what is demand response
What is Demand Response?
  • Mechanisms used to encourage consumers to reduce electricity during times of peak demand; high wholesale prices, or grid emergencies
    • Customers temporarily shed or shift loads in response to a request made by utility
    • Useful in controlling overall energy procurement costs and avoiding emergencies (blackouts)
    • Different than energy efficiency measures
      • Energy efficiency – customers find ways to do the same thing with less power
      • DR – customers go above and beyond EE measures to temporarily curtail or shift load to different times
eventconnect share the power what makes a good customer
“EventConnect–Share The Power”: What Makes a Good Customer
  • Flexibility to shift or shed load
    • Peak load greater than 200kW - willing to sustain a load drop up to 4 hours event
  • Existing building automation system or controls infrastructure
  • Most industrial loads can be simple and easy
    • Stone crushing, recycling, cold storage, and public water agencies are always reliable loads
  • Mid to large size office campuses work very well (5 –10MW+ peak)
    • 5% of peak load is quite easy
    • 10% of peak load is comfortable
    • 20% of peak load is being achieved by many accounts
