Two Demand Response Models Utility Residence Direct Load Control (PCTs) • Radio signal tells appliances to • cycle • shut-off • change set-point on thermostat Residence Utility • Advanced Metering Infrastructure (AMI) • Automated meters • Advanced Meters and Smart Meters • Linked to management systems at the utility • No meter reader: wireless or powerline • Smart Meters (and consumer devices) • “Interval Data” to sub-one-minute • Home Area Network and Smart Appliances • Data on individual appliances • Sometimes gateway, sometimes direct communication • Who controls the HAN gateway and where is it placed?
Non-Intrusive Appliance Load Monitoring (NALM) • NALM: fundamental tool for extrapolating activity
Interval Data • 3000 data points per month for 15-minute intervals – vs. 1 • Virtual biography of household activity in near real-time • Adding specific appliance data (e.g., smart dryers, PEVs) adds even more detail AC, dinner, lights, tv 3 days a week working in LA Lights, shower, tv Assault Me Now Rob Me Now Daily Patterns Weekly Patterns
Privacy implications • New data flows • Granular energy usage data that can be very revealing of home life • Transmission in real-time or near real-time • -Wardriving? • -Wiretapping? • New relationship between utility and consumer • Data flowing to new players and systems • New players and business models • 3rd parties – device manufacturers and service providers (TED, Google PowerMeter, Microsoft Hohm) • Monetization (advertising, etc.) • 3rd party access to information held by new parties • -Law enforcement • -Private parties (subpoenas, business interests) • New risks • Networks • -Many points of attack • -Web-based access: security? • “Smart” meters, with limited physical security • Sensor networks making inside visible/controllable remotely • Applicable regulation/legal protections unclear
Managing Privacy Implications • Baseline privacy standards should be drawn from Fair Information Practice principles • Fair Information Practices (FIPs) • Transparency • Individual Participation • Purpose Specification • Data Minimization • Use Limitation • Data Quality and Integrity • Security • Accountability and Auditing Key Additional Requirements “Notice and Choice” Insufficient NIST work • All Smart Grid entities and practices should be covered: Third party access to and use of revealing usage data is of significant concern and should be carefully considered
