3. What is the Smart Grid? www.sandiego.edu/epic Let’s start with our current grid…

4. www.sandiego.edu/epic What is the Smart Grid? Current Electric Grid Generally Characterized by… One way energy flows to end-users Exception might be net energy metering Centralized energy production Mechanical Few communication nodes How does SDG&E know your power is out? Few control nodes Limited automation Low load factors/asset utilization Monthly contact with the customer Limited information via billing

5. www.sandiego.edu/epic What is the Smart Grid? Let’s Not Forget… The Electric Grid is an Engineering Marvel of the 20th Century however…

7. www.sandiego.edu/epic What is the Smart Grid? What is IBM Telling us? Grid is antiquated The devices we plug into the grid are far more sophisticated that grid Can the current grid support an increasingly digital economy? Innovation happening at edge of grid Grid may not be able to fully optimize those innovations Lots of energy is wasted “Over half of the energy never reaches a single light bulb.” 65% of primary energy used to generate electricity is wasted 9% of electricity is lost to transmission and distribution losses Need to embed intelligence at all points along the grid Appliances Meters Cities The planet! Universe?

9. www.sandiego.edu/epic What is the Smart Grid? What is GE Telling us? We can manage our energy usage better Time of use management This can save money Distribute renewable energy from one place to another We do this now, but not optimally Smart grid communicates across regions

10. www.sandiego.edu/epic What is the Smart Grid? Energy Independence and Security Act of 2007 (EISA) Characteristics of the Smart Grid (Section 1301): Increased use of digital information and controls technology to improve reliability, security, and efficiency of the electric grid. Dynamic optimization of grid operations and resources, with full cyber-security. Deployment and integration of distributed resources and generation, including renewable resources. Development and incorporation of demand response, demand-side resources, and energy-efficiency resources. Deployment of `smart' technologies (real-time, automated, interactive technologies that optimize the physical operation of appliances and consumer devices) for metering, communications concerning grid operations and status, and distribution automation.

11. www.sandiego.edu/epic What is the Smart Grid? Energy Independence and Security Act of 2007 (EISA) Characteristics of the Smart Grid (Section 1301): Integration of `smart' appliances and consumer devices. Deployment and integration of advanced electricity storage and peak-shaving technologies, including plug-in electric and hybrid electric vehicles, and thermal-storage air conditioning. Provision to consumers of timely information and control options. Development of standards for communication and interoperabilityof appliances and equipment connected to the electric grid, including the infrastructure serving the grid.
