The grid today
Utilities committed to proving safe, reliable
power.
Must provide quality service with an aging
infrastructure
Supplying energy in a carbon constrained world
Working with non

Energy Storage
Scenario:
Wind energy is stored in a
battery for use when needed.
Consumers can use wind power when they
want
—
not just when the wind is blowing.
Energy storage devices can be tapped
whenever demand is high.
16
Smart Substation
Scenario:
Digital intelligence gives substation
operators remote control of facilities
.
Allows faster adjustments to conditions
Prevents blackouts, makes for faster
recovery
More flexibility to re
-
route power
Monitors help keep facilities and sites
secure
17
Smart Distribution Assets
Scenario:
A smart meter detects an isolated outage in
a residential neighborhood.
The utility pings the meter and is able to
send the right crew, with the right tools, to
the right location to turn power back on
quickly, OR
Can remotely re
-
connect power
Faster restoration time and fewer outage
minutes
18
Smart Outage Management
Scenario:
A customer’s power goes out at their
home; but they don’t need to call the utility.
Its already located the cause of the outage.
Sensors & monitors embedded throughout
the grid detect abnormalities/disruptions
Real
-
time data leads to rapid diagnosis and
correction
19
Smart House
Scenario:
Home appliances contain onboard
intelligence that receives signals from Xcel
Energy and can reduce demand when the
grid is under stress.
Consumers automatically pre
-
program
appliances to turn on when prices are
lower.
Creates options for managing bills and
energy consumption habits

in Hybrid EVs (PHEV)
Scenario
:
A PHEV is capable of both charging from
and
discharging power to the grid.
Utilities may pay consumers to “borrow”
PHEV energy storage in times of need
PHEVs can also serve as back
-
up
generation for homeowners
Utilities can offer incentives to motivate
charging strategies with environmental
benefits
22
The Smart Grid offers multiple benefits for
consumers, environmentalists, and the
energy industry as a whole…

Investment
Approximately $60 to $100 million
Cost is offset by joint funding from
partners and contributions of:
Utility hardware
IT hardware
Software
Labor resources

Timeline
26
In Conclusion
It won’t happen all at once:
Smart Grid will be an evolution with long
-
term
implications.
Next steps: collaborate with customers,
shareholders and regulators to put scope and final
designs in place.
Start up costs involved; but savings expected in
the long run.
Solid focus will remain on customer choice.
