Detaching AC from MC Rate Decoupling Lowers consumption, therefore results in lower emission Facilitating two-way communication Increase Reliability More accurate pricing structures, hence lower prices for consumers

August 2003 Lasted 3 days Affected 50 million 10 million Canada 40 million in U.S Eastern US and Canada Detroit to New York City and Toronto $10 billion (USD) in economic loses 3,000 fire calls in NYC alone 11 deaths
3
Interconnects – regions of AC connectivity – strictly regulate frequency (60 Hz) Frequency is dependent on load (demand) and supply. When there is an overload frequency drops
5
Transformers and Generators both break down when the AC Frequency changes Generators speed up when frequency drop, overheat Current increases and causes Transformers to overheat and explode…
6
Distributed Energy Systems generate emergency power onsite when supply drops, causing a dip in frequency But there still is a lack of communication about the real demand

13
Prices reflect average, not marginal costs Consumers have little incentive to constrain electricity use when conservation is required Quantity demanded exceeds quantity available Create incentives for decreased electricity consumption during peak periods
14
Real-time market information on prices and quantities demanded and supplied Provide incentives to reduce consumption during peak use periods Regulates supply on each transmission line through prices Encourages increased use in rarely used lines and decreased use in overcrowded lines Encourages increased use during non-peak periods
15
Imagine a toll road where "permits" are auctioned off. The price each person is willing to pay will depend on the number of people on the road Drivers will pay less for a crowded than a less congested road End result is traffic from otherwise crowded roads shifts to less crowded roads and congestion is reduced for everybody. Similarly, spot pricing on a Smart Grid encourages consumers to use less crowded transmission lines. Electricity flow shifts from overused to underused lines Events leading to the 2003 blackout don't occur.
