The Smart Grid is a convenient term to describe the modernization of electric, natural gas, and water grid infrastructures. The term encapsulates the convergence of remote monitoring and control technologies with communications technologies, renewables generation, and analytics capabilities so that previously noncommunicative infrastructures like electricity grids can provide time-sensitive status updates and deliver situational awareness. This chapter addresses privacy in all three of these consumables, but electricity occupies a unique place by virtue of the fact that we can produce it as well as consume it. Organizations need to establish internal privacy policies and supporting procedures for their personnel to follow to provide direction on how to effectively and consistently protect consumer and energy usage data, energy consumption data, and energy production data. Similarly, Smart Grid services and products recipients should be provided with a privacy notice that describes the information the organization is collecting and how that information will be used, shared, and secured.
