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.

Moving beyond the traditional…The Smart Grid will: Be more reliable. Be self-healing and self-monitoring. Be more secure. Be cleaner and greener. Support widespread distributed generation. 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.
![Page 16: Smart Grid City: A blueprint for a connected, intelligent grid community](https://reader035.vdocuments.mx/reader035/viewer/2022062217/56649ca75503460f9496957a/html5/thumbnails/16.jpg)

Smart SubstationScenario:
Digital intelligence gives substation operators remote control of facilities.
Allows faster adjustments to conditionsPrevents blackouts, makes for faster
recoveryMore flexibility to re-route powerMonitors help keep facilities and sites
secure
![Page 17: Smart Grid City: A blueprint for a connected, intelligent grid community](https://reader035.vdocuments.mx/reader035/viewer/2022062217/56649ca75503460f9496957a/html5/thumbnails/17.jpg)
17
Smart Distribution AssetsScenario: 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
![Page 19: Smart Grid City: A blueprint for a connected, intelligent grid community](https://reader035.vdocuments.mx/reader035/viewer/2022062217/56649ca75503460f9496957a/html5/thumbnails/19.jpg)
19
Smart HouseScenario: 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
![Page 20: Smart Grid City: A blueprint for a connected, intelligent grid community](https://reader035.vdocuments.mx/reader035/viewer/2022062217/56649ca75503460f9496957a/html5/thumbnails/20.jpg)

Smart House
Plug-in hybrid electric cars
Added green power sources
Smart thermostats, appliances and in-home control devices
Real-time and green pricing Signals
High-speed, networked connections
Customer interaction with utility

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

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.
