Greening the Cable Plant
New SCTE standards could cut one-quarter of cable’s $1 billion annual energy bill

“Our part of the partnership is to focus on energy and power” for cable networks and operations, notes Mark Dzuban, SCTE president and CEO.
On the energy and power part of the green equation, the SCTE Sustainability Management Subcommittee (SMS) is currently working on drafts of SMS 001, dubbed “Recommended Energy Conversation, Sustainability and Efficiency Practices for Critical Systems” and SMS002, the proposed standards for “Product Environmental Requirements for Cable Telecommunications Facility,” which addresses such issues as temperature and environmental design.
On Sept. 14 in Dallas, the SCTE will hold its semi-annual Smart Energy Management Initiative forum that will cover a number of pressing technical issues. The next day, the draft standards will be unveiled at a meeting of the SMS group. Dan Cooper, senior director of technical operations for Time Warner Cable, is the group’s chair.
Dzuban expects the standards to be completed within six months of the September meetings. “We will have the standards in a final format in 2012 so it can impact the next generation of hardware in 2013 and 2014,” he notes, with some of the biggest savings coming from energy costs in facilities. “That is the low-hanging fruit,” Dzuban says. —GW
The SCTE, which estimates that the cable industry spent about $1 billion a year on energy in 2010 for its facilities and operations, is hoping the new standards could cut those costs by 20-25% a year over the next three to five years.
Over time that would have a significant impact on cable’s bottom line, according to several SCTE projections of possible energy costs. Under one scenario, cable’s energy bills could top $1.6 billion a year in 2017, even if the cable industry doesn’t expand its network.
That seems unlikely. Cisco recently projected that new services, such as TV Everywhere delivery, will more than double traffic over managed IP networks—such as those run by cable operators and IPTV providers—from 2,421 petabytes per month in 2010 to 6,878 petabytes in 2015. That represents a 23% annual growth rate.
If cable networks were to double their capacity to handle that projected traffic, one SCTE estimate puts energy costs jumping to around $3.4 billion by 2017, unless conservation measures are put in place.
In contrast, implementing some SCTEproposed standards to achieve a 25% energy savings could cut those costs to about $2.5 billion in 2017.
“In this case, green is dollars,” says Mark Dzuban, SCTE president and CEO, who calls the society’s Smart Energy Management Initiative, and the work of their Sustainability Management Subcommittee on the new energy and power standards, one of the group’s most important efforts.
“Green initiatives can be warm and fuzzy, but you can only sell that to a point,” Dzuban says. “To make material changes, you have to make a business case as well.”
The projected savings aren’t just theoretical, Dzuban stresses. Since starting its Smart Energy Management Initiative in 2009, SCTE has also worked to implement a host of programs at its own headquarters. The fixes enabled the organization to cut its electricity costs from the grid by 46% during the first quarter of 2011.
The savings came from the installation of a rooftop solar system from Alpha Energy, the use of more efficient LED lighting and the deployment of new servers with advanced processors and more efficient power supplies. The last change was part of a virtualization project that has cut the number of servers needed in half. The project is using a stateof- the-art hydrogen fuel cell system that is capable of providing 64 hours of backup power to its critical IT equipment.
The deal with Alpha Energy also reduced capital costs because SCTE used a Power Purchase Agreement to finance the installation. Under that agreement, SCTE pays a fixed amount for the solar energy used but does not have to buy the equipment.
