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

integrated systems and
processes


Smart technologies can provide solutions to
modern grid challenges.

and
greener
.


Support widespread

.


Help customers better
control energy use

in
their homes and businesses.


Achieve lower throughput, thus
lowering prices.


Xcel Energy is setting a Smart Grid benchmark
among North American utilities.

15

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

Smart House

Plug
-

Added green
power sources

Smart thermostats,
appliances and in
-
home
control devices

Real
-

High
-

21

Plug
-
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…

Smart Grid Benefits

24

Investment


Approximately $60 to $100 million



Cost is offset by joint funding from
partners and contributions of:


Utility hardware


IT hardware


Software


Labor resources

25

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.
