Virginia Tech Approach Highlights
31
Detailed customer usage data is stored at customer premises
Customer data privacy is ensured
Customer can pick and choose which appliances to control
Unidirectional communication with existing communicationchannels leads to lower investment and operational cost,reduction in complexity, and therefore lower deployment risk
This approach allows the citizen, the regulator, the electric utilityand the business partner to gain experience with the smart gridand be convinced of its value without a large up front investment
