+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


5

+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


8

+2. Jury still out on real-time meter data usefulness to customers


9


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

2009 simulation game researchReal-time meter data: No change in energy scores

Appliance-level data: Statistically significant change

What to do?Appliance sub-metering

Load disaggregation

14





What to do?Appliance sub-metering – costs are fallingLoad disaggregation – research is progressing


15

+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


16

+4. Customers want estimated bill impacts

Offer tools with “what-if” scenariosConservation and load shifting behavior

Efficiency investments

Rates

+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?


22

+6. Customers want automation –but many are wary of utility control

Time-of-use ratesProgrammable thermostats

Timers

Dynamic pricing or load controlCommunicating thermostats

Switches


23

+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
