The Smart Grid can be called the merger of two networks : the electrical transmission & distribution network, and the modern data communications network. While communications are not new to the electrical grid, the integration of renewable power generation, electric vehicles, and even consumers themselves into the grid requires the creation of an automated, distributed, and secure control system of tremendous scale, with reliable, flexible, and cost-effective networking as the fundamental enabling technology.

The vertically-integrated Supervisory Control And Data Acquisition (SCADA) system silos of today are yielding to horizontally-layered communications architectures for substation automation, distribution automation, advanced metering, and home area networking applications. The smart grid will use a broad mix of public and private, wired and wireless, licensed and unlicensed, and standard and proprietary communications technologies. It is not uncommon to see private fiber, point-to-point microwave, and satellite for substation connectivity, with 3G cellular and thousands of unlicensed private RF mesh nodes in the distribution network within a single utility. But regulatory pressures, coupled with government funding, is spurring unprecedented standards development, challenging today’s proprietary systems with internet-inspired network equipment. And datacom networking vendors are rushing to compete with established grid vendors for the smart grid opportunity.
This report examines the current state of grid communications and emerging application requirements, and defines the devices, technologies, and services within the smart grid communications universe. Unit forecasts are provided by grid application, device types, and up to 18 different public, private, wired, and wireless communications technologies. Revenue forecasts by network devices and for public carrier services are also provided. All these are further divided by region, taking into account the different structural, technical, regulatory, and funding environments in each region.
