+Background
Sacramento Municipal Utility District (SMUD)Fifth largest municipal utility in the nationCustomer-ownedHighest customer satisfaction in the nation 2007, 2008
Second highest 2009, 2010
Sacramento Smart Grid2009 federal funding $127.5 millionAdvanced metering infrastructure (AMI) planned completion by 2012Research focus: small customers + the smart grid

Behavior, Energy, and Climate Change Conference
+Customer Benefits
Information better understand energy useReal-time meter data to customersInformation flow between utility and customers
Incentives opportunities to earn or save $$Time of use and dynamic pricingPayment for load drop during events
Controls better manage energy useUtility-controlled through Smart GridCustomer-controlled independent of Smart Grid
November 16, 2010Behavior, Energy, and Climate Change Conference

+Existing Systems(not Smart Grid)
Monitor energy use – site or appliance
Display electricity prices
Estimate energy costs
Notify customers of utility price or event signals
Centralize customer control of appliance activity
Automate response to utility price or event signals

Lessons Learned (so far)
November 16, 2010
Behavior, Energy, and Climate Change Conference 7
+1. Customers want personalized advice
Include energy assessments in the list of benefits for joining other utility programs
Offer simple, inexpensive on-site energy assessments
Use the opportunity to recruit for EE and DR programs

+2. Jury still out on real-time meter data usefulness to customers
Literature shows mixed results
Customers say they want appliance-level info
2009 simulation game researchNo change in scores for site-level data Statistically significant change in scores for appliance-level data
What to do?Appliance sub-meteringLoad disaggregation

+3. One size does not fit all
Focus groups findingsSplit opinions on who should manage loads
Split opinions on technology form factors, features, financing (MTKD?)
What to do? Offer a portfolio of mix-and-match energy management tools + incentives
Efficiency measures + rebates
Customer-controlled automation + dynamic pricing
Utility-controlled automation + payments
November 16, 2010Behavior, Energy, and Climate Change Conference

+4. Customers want estimated bill impacts
Offer tools with “what-if” scenariosConservation and load shifting behavior
Efficiency investments

+5. Presentation of Tier + TOU rates …is complex
Battle of the billsList all prices?
2 tiers x 3 TOU = 6 pricesList deltas relative to old rate?
Need to understand old rate to understand newList deltas relative to new rate?
TOU delta relative to tiersTier delta relative to TOU prices
How to mesh bill presentation with new real-time information display?

+6. Customers want automation –but many are wary of utility control
Time-of-use ratesProgrammable thermostats
Timers
Dynamic pricing or load controlCommunicating thermostats
Switches
November 16, 2010Behavior, Energy, and Climate Change Conference

+7. Customers want assurance of privacy and security
Inform customers of cyber-security plans
Limit data collection to the essentialsLeave appliance-level data in the home unless customers specifically request or allow otherwise
