BPL: Stayin’ Alive?

Broadband over Power Line (BPL), an emerging technology that utilizes existing power lines to transport data at broadband speeds, is in the process of redefining itself. Though this action may be seen as a way to meet the needs of an evolving market, it is also necessary for the technology’s survival. BPL has had a difficult time breaking into a space that pits it against the large telecom and cable companies whose names are known.
Last November IDC Research released a follow-up report to its July 2005 report, “Broadband over Power Line: Impact for Utility Companies.” The recent report, “TXU Puts BPL in Spotlight, Possibly for BPL’s Swan Song” begins, “With Google Inc., Goldman Sachs Group Inc., and the Hearst Corp. jumping on board as investors, the BPL industry seems like it should be taking off. Yet, especially after many failed standalone consumer broadband pilots, most North American utilities are still reluctant to adopt BPL.” More recent articles indicate that the tide may be changing. In its article, “Broadband over Powerline Use Expected to Grow,” PC World refers to an analyst from Parks Associates in Dallas who estimates, “that there are today no more than 150,000 BPL users in the U.S.;” that figure is expected to, “rise to 2.5 million by 2011, especially in rural areas unserved by cable or DSL.” Ralph Vogel, spokesmen for Utility.net, a Los Angeles-based BPL integrator is optimistic about BPL as well. Quoted in the same PC World article he says, “We are at an inflection point in the industry . . . Its position is similar to that of DSL in the late 1990s: people have heard of it, and while we were previously not quite there yet with the technology, we are now.”
One reason for the new interest in BPL is the FCC’s clarification of their position on the technology. Access Intelligence reports that the FCC is, “essentially giving the industry carte blanche to forge full steam ahead, with only some minor caveats to help ensure that access BPL does not emit RF radiation that would interfere with other legal spectrum uses.” This may be a bit of an overstatement; the American Radio Relay League (ARRL) reports numerous trial deployments have been shut down and the status of many more is pending. Regardless, the FCC’s clarification and its relaxed legislation have made BPL more palatable. However, the sole reason for the change of heart does not lie with the FCC, much of it may be due to a new tact being taken by the industry.
BPL vendors initially proposed the technology as an alternative to DSL and cable Internet access. Confronted head-on with the inability to crack that market, for reasons which include low churn rates of major DSL/cable providers and lack of name recognition, BPL proponents repositioned the technology as, “an enabler of the intelligent grid.” Consumer broadband has now taken a back seat to remote meter reading, transformer monitoring, and the real-time relay of grid data. According to PC World an average of 500,000 Americans a day lose power for at least two hours; this adds up to a loss of $180 billion for the utility companies. Clark Gellings, vice president of the Electric Power Research Institute, a nonprofit research consortium in Palo Alto, Calif. estimates that a smart grid could cut those losses by 80 percent. Furthermore, electric meters that automatically report usage would eliminate the need for meter readers and allow for additional features. In its new incarnation, BPL is attempting to place itself as the solution for utility companies. While the repositioning may have been necessary for BPL’s survival, it is at the same time risky; the intelligent grid does not depend on BPL. In the new arena BPL is still up against the same competition, fiber optics and wireless technologies, when it comes to the real-time transmission of remote sensors to the control room. However, it is with this new face that BPL is making strides, most recently and notably in Texas.
IDC reported that TXU Electric Delivery had undertaken a $150 million partnership with Current Communications to “install a BPL network for more than 2 million Dallas, Fort Worth customers;” the rollout was anticipated over the next 10 years. These numbers have been updated since the IDC report was published. According to PC World, the TXU deployment “is likely to be the next big BPL installation, as it has committed $450 million to install 3 million smart meters, explained spokeswoman Carol Peters.” Peters said further that, “We expect the vast majority of our system to be operating over BPL by 2011.” While the network will provide customers the option of broadband Internet access, in keeping with the technology’s new alignment, its focus is “intelligent grid applications.” As IDC puts it, “Although this high-profile partnership provides a tremendous opportunity to prove BPL benefits, if the project fails, it could have a devastating impact on BPL’s prospects with already wary utility companies.” It should be pointed out here that while North American utility companies may be wary, this feeling is not necessarily shared by those of other countries.
Korea Electric Power Corp. announced its plans to deploy 16 million smart meters by 2010 while it replaces older analog models. While in France, SIPPEREC plans a deployment which will reach 1.5 million homes in suburban Paris. IDC which reports those numbers, poses two reasons for slower adoption in North America: regulatory hurdles and infrastructure investment. While regulatory hurdles imposed by the FCC have been largely overcome, their existence acted as an impediment in the earlier days, and put North America behind other countries. Furthermore, in countries where BPL has been more actively adopted there is less of an investment required for the supporting infrastructure. The United States has a lower transformer to customer ratio and with equipment needed at each transformer, “U.S. utilities have to install more infrastructure to serve fewer customers.” One subset of the market where this does not apply is the multidwelling unit (MDU), namely hotels and apartments.
“In MDUs, BPL provides building owners and property managers with a way to provide in-building Internet access that costs less and takes less time to install than competing technologies, particularly for existing buildings. Also, customers can install BPL in a building regardless of the communication technology connecting the building with the Internet.” IDC lists Sandman Hotels, Inns and Suites which uses BPL at all 31 of its hotels, and the 253 unit Maryland luxury apartment building the Whitney as MDUs where BPL has been successfully deployed. Interestingly, both these examples are instances of Telkonet deployments.
According to Access Intelligence Telkonet’s customer base, “now totals about 300 hotels with a combined total of 30,000 rooms plus about 20,000 apartments in complexes around the Americas.” While the company is the niche leader it is looking to expand in other directions, and with some government assistance it might just make it. Access Intelligence says the, “U.S. Department of Homeland Security has decided to use Telkonet widgetry as its broadband network in airports all over the United States.” The company may also be hedging its bets; it will be unveiling the prototype of a “custom product for remote monitoring and management of utility substation equipment;” this for GE Energy.
Though the results of the TXU/Current Communications deployment are much anticipated and may very well predict whether or not BPL can make a stand, the market is not standing idle. Still in its evolutionary stages the BPL market continues to play host to new companies trying to turn the challenges of a nascent technology into opportunities. As newcomers such as PowerGrid Communications and BPL Global try to gain traction a few have established themselves as leaders of the pack. Ambient Corp. and Current Communications have emerged as the major players; both benefit from strong investment, FCC certified technologies, and experience deploying BPL technology. Both companies have big names in their corners: on the Internet side of things, Ambient has Earthlink while Current has Google; as far as partnerships in the power industry Ambient is working with ConEdison and Current with TXU Electric Delivery. Names such as these being involved may be another reason BPL is still on the map.
The verdict is still out in the trial of BPL, and its future is anything but certain. As some of the titles of recent research suggest, the world may be preparing to “Flip the BPL Switch,” or it may soon witness “BPL’s Swan Song.”

Bill Would Allow Broadband over Power Lines
Arkansas Business, March 6, 2007
The state Senate is considering legislation that would allow electric utility companies to deploy broadband networks over power lines, a development that could potentially offer Arkansans access to the Internet through the same home wiring that powers their living room lamp. House Bill 1589 would allow Arkansas electric utility companies to implement broadband over power line (BPL) technology.

Broadband over Powerline Use Expected to Grow
PC World, March 2, 2007
Some call it “the third wire” and others call it “broadband over powerline” (BPL). But for Tim Barhorst, a technology consultant in Cincinnati, it’s his Internet connection. “It seems equivalent to standard cable service and a little faster than standard DSL,” he noted. “But the speed is not asynchronous, meaning you get the same speed upstream and downstream.”
