2 The Current State of the Grid Current grid tends toward dumb We typically learn about outages via phone Many substations are not automated Many functions are performed manually in the field No automation in homes By the time customers get their bill, it s too late to do anything about it One benefit of the dumb grid not as open to cyber attack

3 It s Time to Upgrade!

4 It s Time to Upgrade!

5 Smart Grid Vision

6 Tangible Benefits of Smart Grid Reduce peak load Reduce losses Improve energy efficiency Faster outage restoration Promote distributed generation Improve air quality Integrate intermittent renewable resources The Smart Grid Project allows customers to be part of the energy solution.

7 SmartSacramento ARRA Grant Distribution Automation ($55.0M) Smart Meters Consumer Behavior Study ($10.5M) ($142.2M) SMUD received a $127.5M Smart Grid Investment Grant from DOE to implement $307.7M integrated project Technology Infrastructure ($27.2M) Cyber Security ($5.3M) Customer Partnerships ($47.1M) Demand Response ($20.4M)

8 What SMUD is Doing 1. Smart meter installation 2. Consumer behavior study 3. Demand response 4. Distribution automation 5. Customer applications 6. Technology infrastructure 7. Cyber security 8. R&D Projects

9 Smart Meter Installation SMUD has installed over 250,000 meters to date. SMUD will install 615,000 Smart Meters by Q Customers receive a letter & brochure before meter is installed. They don t have to do anything, except remove barriers to access. There is no need to be home for the meter installation. Customers won t notice any big changes at first.

10 Better information for customers Detailed energy information Yesterday s usage today Choices for managing energy

11 Consumer Behavior Study Conduct a consumer behavior study that will be used to develop strategies for rate design, provide information on automation, measure satisfaction by demographics, and measure value for the consumer and SMUD. The effort will provide a statistical measure of the ability to reduce electricity use, reduce peak demand, and determine the likelihood of participation by demographic. As part of the consumer behavior study, install a suitable number of programmable communicating thermostats to measure and study behavior.

12 Demand Response Install Demand Response Management System software. Install up to 10,000 Home Area Network and energy management devices to allow homes and small commercial businesses to participate in direct load control and pricing programs. Design and deliver programs for medium & large commercial customers to automatically respond to peak prices by reducing load (Automatic Demand Response).

13 Distribution Automation Retrofit 35 substations with SCADA. Install intelligent switching and monitoring equipment on 90 feeders (line automation) and CVR. Install an advanced operations management system for voltage control and automatic restoration.

14 Customer Applications Partner with California Department of General Services, California State University Sacramento, Los Rios Community College District, and County of Sacramento to design, procure and build energy management systems and plug-in electric vehicle charging stations. Develop services and solutions for residential and commercial customers that educate, inform, and enable them to access and use the information available through the smart grid system to better manage and control their energy use. Develop a pilot program to install up to 180 electric vehicle charging stations for residential customers.

15 SMUD s Smart Grid Partners SMUD Sacramento Municipal Utility District SMUD is partnering with four public agencies to implement the Smart Grid grant. Sacramento County CSUS California State University, Sacramento SGIG Smart Grid Investment Grant DGS California Department of General Services LRCCD Los Rios Community College District Partners SMUD Sacramento Municipal Utility District LRCCD Los Rios Community College District DGS CA, Department of General Services CSUS California State University, Sacramento Sacramento County County of Sacramento

16 Technology Infrastructure Install Enterprise Service Bus software platform to allow various systems to communicate; reduces the number, size, and complexity of integration interfaces between systems in order to reduce cost and improve speed of service to the customer. Install Customer Relationship Management System software that integrates customer service call center with back office billing system; provides customer representatives a real-time view of energy usage.
