Home Energy Monitoring


Published on

When a consumer has easy-to-access information about their energy use, they have the power to change their consumption patterns. Having real-time energy consumption data can potentially save you 10-35% . Come learn how the smart grid and smart meters will impact residential consumers' electricity rates and how a home energy monitoring system can assist you in being more energy efficient.

Home Energy Monitoring

  1. 1. Home Energy Management What you need to know… Presented by KC Jacobson VP Business Development giving people power over energy in conjunction with
  2. 2. Knowledge is Power How can consumers benefit?
  3. 3. What is the Smart Grid? Inspired by • increasing demand, especially at peak • rising rates • need to accommodate renewable input • improve reliability & security • need for more flexibility Moving from 1-way centralized network Towards dynamic decentralized networks with bidirectional flow of energy AND DATA
  4. 4. Smart Grid:It’s All About Communication Electrical Power System From Generation to End Use Advanced Sensors and Computing Interconnected by Communications that Reach Every Device
  5. 5. Today’s Reality for Consumers Energy Prices Rising Retail Price of Electricity in California • Cost of electricity increases every year 19.000 Deregulation • New Smart Meters 15.500 Experiment Cents/kwh are coming 12.000 Increased “Green” 8.500 Sensibility 5.000 • Dependence on 1U.S. 1980 1985 1990 1995 2000 2005 Energy Information Administration Report 2010 foreign energy sources Consumers are motivated to make • Reducing carbon footprint changes.
  6. 6. Electric Company Motivation Peak Demand is the Enemy • Higher cost of generation = Lower margins • Operating costs are increasing • Permits for new Cost of Electricity Generation in California power plants 900 800 and distribution Total C os t of P roduc tion 700 (inc luding debt s ervic e and lines increasingly 600 operating c os ts ) 500 difficult to obtain $/MWH 400 R etail P ric e 0 5000 10000 15000 20000 25000 30000 35000 40000 45000 (MW) 1California Energy Commission, “An Action Plan to Develop More Demand Response in California’s Electricity Markets”
  7. 7. Traditional Tools are are Limited Information on the Electric Bill • Utility bills hard to understand • Tiered rates are confusing • Consumers don’t know what individual appliances, etc. cost to use Electric Company Energy Audits • Based on standard profiles & forms • No actual data on personal energy use • Recommendations can be expensive, inconvenient
  8. 8. Smart Meters Alone Won’tChange This Default communication is utility  Smart Meter Rate structures will become more sophisticated • Time of Use (TOU) Metering • Rates can change every 15 minutes to reflect utility costs • Utility may offer rebates & discounts to encourage energy efficiency
  9. 9. To Benefit…Consumers MUST be Proactive! What does this mean for me? Need real-time data… • Big picture: Effectively reduce peak demand • Closer to home: Reduce utility bills Can’t change behavior without feedback Access to usable data will save you $$$ Don’t forget Privacy considerations
  10. 10. Home Energy ManagementSystems (HEMS) are the Solution Variety of Systems Available• Meet needs of all types of consumers• Many price points• Levels of detail & control Types of monitoring & management• Monitor & control devices (programmable thermostats)• Monitor whole home – HW and/or SW• Monitor circuit-by-circuit or room-by-room
  11. 11. HEMS Communicationsto Suit Every Need Internet - Google, Microsoft Device display –TED, KillAWatt, Thermostats WiFi – Tendril, Control 4 ZigBee – Control4, EcoDog, smart appliances PowerLine Carrier (PLC) – EcoDog
  12. 12. Control Philosophies Set it & forget it – e.g. thermostats Utility control – usually in exchange for rate discount Interactive consumer control • Software • Hardware Hybrid models
  13. 13. Benefits of HEMS “Prius” Effect: Awareness half the battle Typical savings 10-25% Added savings by identifying “Energy Hogs” • Faulty appliances • Older devices More savings from: • Control capabilities • Usage analysis
  14. 14. Impact on Alternative Energy Home Energy Management can enable consumer to optimize alternative energy installations Some systems include detailed monitoring of energy input as well as demand Can enhance efficiency and help calculate return on investment
  15. 15. Changing Consumer Behavior ‘Prius Effect’ Solutions as individual as consumers • Utility bill vs affordability • Choices for those who want more control • Alternatives for those who want utility to control • Some will chose to do nothing Utility Incentives will be key • Rate structures • Rebates & incentives • How incentives delivered to consumers
  16. 16. The Results Savings for consumers can be significant Potentially the most effective means to: • Reduce costs • Reduce energy consumption • Reduce carbon emissions • Reduce need for new power plants
