12 Case for Grid Modernization & Value Proposition
13
13 Why Modernize the Grid? Today’s grid is aging and outmoded Unreliability is costing consumers billions of dollars Today’s grid is vulnerable to attack and natural disaster An extended loss of today’s grid could be catastrophic to our security, economy and quality of life Today’s grid does not address the 21 st century power supply challenges Adverse trends associated with the grid - Costs, reliability, peak loads, asset underutilization, TLRs, grid divorce The benefits of a modernized grid are substantial
14
14 Value Proposition Cost to Modernize $338-$476B over 20 years –$ 82-90B for transmission –$232-$339B for distribution –$24-46B for consumer $17-24B per year Benefit of Modernization $1294 – 2028 Billion Overall benefit-to-cost ratio of 2.8 to 6.0 14 EPRI, 2011 Previous Studies Benefit to Cost Ratio for West Virginia of 5:1 Benefit to Cost Ratio for San Diego of 6:1 Benefit to Cost Ratio for EPRI (2004) 4:1-5:1 $165B Cost $638 - $802B Benefits EPRI Report: http://www.smartgridinformation.info/pdf/3272_doc_1.pdf
15
15 Who are the Beneficiaries? Utilities (What’s in it for my shareholders?) Consumers (What’s in it for me?) Society (What’s in it for us?) We get what we reward!
16
16 Utility Value Proposition Opportunities Rate of return Operational Benefits –Outage restoration, billing, reduce T&D losses, optimize asset utilization, maintenance, planning Improved Customer Satisfaction Cost Risk of cost recovery Utilities are the engine for investment in Smart Grid
17
17 Consumer Value Proposition Opportunities More reliable service Reduce business loss Energy bill savings Transportation cost savings Information, control, options Sell resources into the market Cost “Consumer always pays” Is this compelling?
18
18 Societal Value Proposition Opportunities Downward pressure on electricity prices Improved reliability reducing consumer losses Increased grid robustness improving grid security Reduced emissions New jobs and growth in GDP Revolutionize the transportation sector Reduce import of foreign oil Cost No incremental cost? Does the societal value proposition make it compelling?
19
19 Smart Grid Implementation Challenges and Risks
20
20 Change Management A significant change management effort is needed: Why do we need to change? What is the vision? Who’s in charge? What is the value proposition? Consumer education, alignment, and motivation is critical Metrics needed for accountability and to monitor progress Active leadership by stakeholder groups needed Move at the “Speed of Value”
21
21 Technical Challenges Interoperability and scalability Large number of consumers actively involved Decentralized operations with 2-way power flow Getting the communications right “Future proofing” the technologies Cyber Security Conversion of data to information to action Market driven Where will we find the skilled resources to solve these?
22

53 M2M Communications Agricultural Demand Response Program Saves Electricity in California Key Activities M2M Communications of Boise, Idaho, has developed a two-way, web-to-wireless controller for irrigation pumps. The controller is part of an irrigation load control system that includes sensors, smart meters, and other monitoring equipment. M2M created the Peak Energy Agricultural Rewards (PEAR) program, a demand response program marketed to agricultural customers of California’s investor owned utilities. Aims and Strategies As part of the PEAR program, farmers can earn cash incentives and avoid peak demand charges. Water consumption and soil moisture can be monitored from a web portal, enabling farmers to make informed decisions about possible participation in peak demand events. Farmers can schedule irrigation pump start up/shut off, saving water, time, and manpower, and improving overall efficiency. Results and Benefits DOE ARRA funds greatly contributed to M2M’s final R&D push to get the controller to market. PG&E called four peak pricing events in 2011; PEAR program participation reduced summer peak demand by an average of 18 MW per event.
