Automating the distribution system to meet changing consumer needs. The value of electricity distribution system transformation—fully automated and integrated with communication—derives from four basic functionality advantages: 1. Reduced number and duration of consumer interruptions, system fault anticipation, and faster restoration. 2. Increased ability to deliver varying “octane” levels of reliable, digital- grade power. 3. Increased functional value for all consumers in terms of metering, billing, energy management, demand-response, and security monitoring, among others. 4. Access to selective consumer services including energy-smart appliances, power market participation, security monitoring, and distributed generation.

Transforming the meter into a consumer gateway that allows price signals, decisions, communications, and network intelligence to flow back and forth through the two-way energy/information portal. Integrating distributed energy resources. The new system would also be able to seamlessly integrate an array of locally installed, distributed power generation (such as fuel cells and renewables) as power system assets.

In order to achieve this goal, national policies should facilitate rapid deployment of all broadband technologies, including BPL. Policymakers at all levels should coordinate their efforts to promote a minimally intrusive policy framework for such technologies. that the provision of high-speed communications capabilities over utility poles and electric power lines (Access BPL) provides an opportunity to increase the competitive broadband choices that are available to customers and the power supply system management options of utilities. that Access BPL may help provide additional power supply system communications and control capabilities to improve reliability and efficiency. Such capabilities include “self-healing” network capabilities; improved security from physical and cyber threats; facilitating use of distributed generation; customer and utility control of appliances and equipment energy use; improved load management and electric grid utilization
