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)

“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 and CPUC

(Coming soon to all IOUs)

SCE Mission

SCE Comprehensive HVAC exists to:


support the HVAC goals of the CPUC


p
rovide a catalyst for continuous improvement


demonstrate fiduciary responsibility to SCE customers


Starting with packaged AC equipment

Comprehensive HVAC

A vision for an integrated HVAC portfolio driving

market transformation

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


Upgrade existing and “to code” Units when premium
HVAC equipment cannot be installed


Installation of Enhanced Ventilation Measure first

Combined Installation of both Technologies third
opportunity


Both technologies provide ADR potential

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!

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



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
