Power Line Communications (PLC) has been used since the 1890s to send low level telecoms signals out to activate or deactivate devices along the electricity grid. This technology was further developed over the last century and is used, for example, for the off-peak hot water service that most electricity companies offer their customers nowadays. Broadband Power Line (BPL) started to arrive in the late 1990s. Simultaneously the energy companies are also being forced to look for telecoms solutions for their core business and are looking at Demand Side Management services to better manage their network, offer better services to their customers and handle the gigantic increase in electricity demand throughout the world and at the same time manage security issues and the environmental impact of all of that. The move from PLC to BPL could well lead to a 3rd national broadband platform to the home next to telecoms and digital TV.

Utilities and telecommunications
Much has been said of the lack of infrastructure competition in the Australian market, and one sector that after some rough starts are now successfully entering the telecommunications business is the utility industry. Players like PowerTel, Uecomm and TransACT are early examples of business borne out of power companies.

However, by the 2000s the focus had changed to broadband based Customer Access Networks (CANs). Over the last five years more than 35 fibre loops have been built by utilities in cities and towns around the country.

Key players
UtiliTel is an informal forum of electric power utilities that have been co-operating over the past several years to canvas and pursue mutual interests relating to their telecommunications assets. A number of UtiliTel members have commercialised their telecommunications activities and some hold carrier licences, or have otherwise moved to provide infrastructure or end services to the telecommunications industry.

Key players here include Aurora, Country Energy, Silk Telecom, Nexium, Transgrid and others. State governments became active promoters of utilities-based broadband projects. UtiliTel is another initiative in this respect. This report overviews these initiatives and the first utilities-based broadband projects that are emerging.

Broadband Power Lines
It is a natural extension of business activity for a power company to enter into telecommunications. New developments in Broadband Power Line (BPL) technologies are making it possible for these utilities to enter the more lucrative broadband market.

Power utilities could play a key role in broadband infrastructure competition. However, problems exist in relation to international standards and radio interference. This last issue is being fiercely debated and needs to be resolved before commercial deployment can take place. ACMA has created a regulatory environment that allows for BPL trials and pilots.

After technical trials in 2004, commercial trials were launched during 2005 in Hobart and Queanbeyan. Full commercial operations are expected in late 2006. Large-scale rollouts are still at least one or two years away.

3rd national broadband platform
Power Line Communications (PLC) has been used since the 1890s to send low level telecoms signals out to activate or deactivate devices along the electricity grid. This technology was further developed over the last century and is used, for example, for the off-peak hot water service that most electricity companies offer their customers nowadays. BPL started to arrive in the late 1990s.

Simultaneously, the energy companies are also being forced to look for telecoms solutions for their core business and are looking at Demand Side Management services to better manage their network, offer better services to their customers and handle the gigantic increase in electricity demand throughout the world and at the same time manage security issues and the environmental impact of all of that. This could well lead to a 3rd national broadband platform next to telecoms and digital TV.

Technical issues
The report discusses the many variations in Low Voltage and Medium Voltage powerline architecture, including the ‘small transformer’ system used in North America and the ‘large transformer’ approach used in 230 volt countries. Propagation, attenuation, interference and other characteristics of these networks result in a variety of architectures for access BPL networks.

Standards-setting include:

Institute of Electrical and Electronics Engineers (IEEE) and powerline communication industry associations;
HomePlug 1.0 in-home PLC system and its successor, HomePlug AV (Audio Visual)– on which the access technology HomePlug BPL will be based;
OPERA BPL standard and survey of powerline architectures, attenuation and noise;
Universal Powerline Association (UPA).
The report surveys the technical principles and performance of major BPL access systems from manufacturers including Motorola, Mitsubishi, Amperion and Current Technologies, including their BPL trials, including the actual performance of second generation Mitsubishi equipment, and commercial services including a 256Kb/s rural BPL service and some multi-megabit/sec services in urban USA and Europe.

After discussing the best known objection to BPL access services: interference, we examine the better established alternative technologies which BPL typically competes with, particularly those technologies which might be more easily deployed by a power utility. Finally, we discuss the barriers which BPL access systems must overcome if they are to achieve the long awaited wide adoption and low costs.
