Smart Grid City: A blueprint for a connected, intelligent grid community
2 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.
3 “Analog” Grid Centuries-old design
4 “Smart” Grid Digital intelligence infused throughout the grid Energy storage devices Local power generation Digital sensors and controls Real-time data Real-time price signals Broadband communications Smart Homes Smart Buildings Electric transportation
5 Drivers for change Grid reliability Aging assets, heightened load Environment: Global climate concerns State mandates for green power Energy Security: Homeland security Dependence on foreign oil Customer Choices: Growing needs and expectations Desire for greater flexibility and options
6 The grid of tomorrow Over the next 10 to 20 years, our industry can evolve more rapidly than ever before. It’s more than just smart meters! DISTRIBUTED RESOURCES POWER GRID MANAGEMENT CUSTOMER POWER MANAGEMENT Distributed generation interconnection Solar Wind Fuel cells Batteries Energy storage Real-time monitoring Transmission/ distribution automation Demand response (adjusting to grid conditions) Broadband over power lines (BPL) Smart meters Smart buildings & equipment Smart appliances Plug-in hybrid electric vehicles (PHEVs) Voltage regulation/ Pre-set energy use
7 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.
8 Xcel Energy’s strategy Smart Grid is an end-to-end solution Aligned with environmental goals Consumer-focused approach Service-based business model Joint R&D partner investments Smart Grid Consortium formed in 2007
9 Accenture: IT and business modeling Current Group: High-speed communications Schweitzer Engineering Labs: Substation technology Ventyx: Workflow management software Xcel Energy imagine. inspire. innovate.
10 Smart Grid City - Boulder, Colo. “An international showcase of smart grid possibilities… a comprehensive demonstration of an intelligent grid community” Test technology Integrate smart grid portfolio of projects Prove benefits
11 Smart Grid City Involves the entire energy pathway from the power source to the home and all points in between Rich in IT High-speed, real-time, two-way communications Sensors enabling rapid diagnosis and corrections Dispatched distributed generation (PHEVs, wind, solar) Energy storage In-home energy controls Automated home energy use
12 Boulder’s Key Strengths Ideal size (50,000 customers/meters) Ideal geographic location (easy access to needed grid components) Ideal Smart Grid consumers: Web-savvy, early adopters Environmentally aware Collaborative opportunities with: University of Colorado National Center for Atmospheric Research National Institute of Standards and Technology City leaders
13 Smart Grid City projects Power Production Energy storage Distributed generation Utility Operations Smart Outage Management Smart Distribution Assets Smart Substations Consumer Smart House Plug-in Hybrid Electric Vehicles
14 Smart Grid City projects
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
20 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
22 The Smart Grid offers multiple benefits for consumers, environmentalists, and the energy industry as a whole…
23 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
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.
