Scenario
After getting home in the evening, Bob opens the Smart Grid application to check his overall power consumption for the day. He notes that this consumption is higher than usual. To find out why, he examines the power usage of his devices in more detail, discovering that much of the power is being consumed by his central air conditioning.
To see whether the additional power use is costing him much money, Bob looks at the current price information being provided by the grid. He finds that it is a peak usage time and that prices are high.
In order to save power and money, Bob increases the set point of his air conditioning by several degrees. He also decides to sell some of the power that he will save back to the utility company, taking advantage of the peak-time prices. He schedules a transaction to take place an hour in the future, saves it, and closes the application.
