  3. What is Demand Response? Why is itrelevant? • Blackouts are a recurring event in the U.S. today – some small, some widespread • One of the main reasons for blackouts can be unusually high demand for power • This can lead to a critical peak load situation on the energy grid • Utilities can prevent peak situations from escalating by shedding load • Load is shed via customers that are signed up for a Demand Response program System load without instigating DR event How does event-based and automated DR work? System load with instigating DR event Building's energy demand from grid Load • A third party or DRMS send a load shed notification • Load shedding done by switching off devices and engaging Onsite Generation and Storage • Process follows rules set by building operator • Rule set provides building owner complete control while the automated system ensures real-time execution • System performs verification of DR action and records credit with utility time Event  Participating in automatedDemand Responsestabilizes our energy supply providing utilities a source of “virtual peaking power.”

  4. Trigger ERCOT initiates as a final measure before resorting to rolling blackouts Event History Only 3 x in 20 years (Dec. ’89, Apr. ’06 & Feb 10 ) had program been in place Testing Up to 3 x / year, lasting approximately 15-30 minutes Event Duration Up to 8 hours per 4-month period Event Limitations 1 event / day; 2 events / 4-month period Eligibility Interval Data Recorder (IDR) meter Notification 10 minutes advance notice Response Types Curtailment and/or generation Penalties • Suspension for those who do not meet availability or testing requirements • Aggregator to assume financial penalties ERCOT Sponsored Demand Response Program What is Emergency Interruptible Load Service? An ERCOT program designed to prevent blackouts when demand exceeds supply
