PV Penetration at Circuit Level PV Penetration by Circuit in SDG&E's Service Area 1,000 Number of Circuits 900 > 30% 800 20% to 29% 10% to 19% < 10% 700 600 500 2010 2011 2012 2013 2014 2015 2016 Customer Adoption of PV Commercial & Industrial Net Energy Metering (NEM) Residential NEM Megawatt Nameplate Capacity 200 180 160 140 120 100 80 60 40 20 0 2000 Time Period 2013 Need More Flexibility An Illustrative Outlook at the California Grid 2013-2020 - CAISO The opportunity • Smart Meters have opened a door to new products and services for our customers • • • ZigBee chips in the meter allow for wireless communication into the home In Home Displays connect directly to smart meters to provide near real-time energy consumption Programmable Communicating Thermostats (PCT) or plug load control (PLC) devices respond to demand response signals, remote control and price preferences • These new products and services provide an opportunity for a strengthened utility / consumer relationship • Customer programs are being designed with HAN technology in mind • HAN enables utility and the customer to maximize the value of smart grid investments 2011 HAN Pilots Internet Gateway Solution with In-Home Display and PCT using SEP 1.0 720 customers: Residential & Small Business • What worked: – Customers liked having the real-time consumption information – Participants with technology only saved 9% over 3 months – Participants with technology and social gaming contest saved 17% over 3 months • What didn’t work – 40% of Internet Gateways were off-line at any given time – HAN devices did not interoperate as expected – 70% failure rate in Small Business installations – SEP 1.0 interpretations 2012 HAN Pilots Reduce Your Use (RYU) In-Home Display Pilot – 650 customers received Rainforest In Home Displays – kW only displayed on IHD – Customer eligible for the higher incentive credit – Customers saved 8% on RYU event days compared to 2% for customers without technology – When surveyed, customers were eager for more information on what they could do to save 2012 HAN Pilots Reduce Your Use (RYU) Thermostat Pilot – Internet connected thermostats were made eligible for the RYU enabling technology credit – Alarm.com and Energy Hub marketed the offering and sent DR signals – Customers saved 27% on RYU event days – Application requirements were a barrier to enrollment (sample size less than 100) Retail Enablement Limited utility role where customer can purchase a devices at retail independent of the utility ZigBee Smart Energy Profile certified device manufacturers were invited to submit devices for testing starting September 2012 – 39 applications submitted: 13 passed / 9 failed – Types of devices submitted: IHD, PCT, GW, PLC – Reasons for failures: • Vulnerable to remote control commands and vulnerable to disruptive device attacks over the air • Device GUI could not be installed successfully in order to start testing • Device failed to indicate lost communication with meter • Failed to commission to new meter during meter swap test Customer Connection Request Customer fills out on-line form E-mail is auto-sent to HAN In-box (sdge.com/han) Eligibility check is completed Device is provisioned to the meter Customer is notified when device is ready to join meter Number of customer requests by device: Manufacturer Type Aztech S-0600 22 Control 4 EC-100 1 Digi ConnectPort X2e 2 Energy Aware Power Tab 20 Energy Hub Home Base 1 Rainforest Eagle 73 Rainforest EMU-1 5 Rainforest EMU-2 80 Rainforest RAVEn 27 TOTAL Retail 231 2012 HAN Pilots Couple HAN technology with TOU rates to get maximum load reduction and energy efficiency – Demand Response Programs deploying 50k Programmable Communicating Thermostats to TOU-Plus and CPP-D customers – Customer Choice: Offer incentives/rebates on validated standards based HAN devices – Package HAN devices with other program offerings for a complete energy management bundled solution CPP Rates HAN Technology Max Load Reduction
