Efforts by the Society of Cable Telecommunications Engineers to develop standards for energy usage are part of a large industry initiative on green technologies. In related moves, the National Cable Telecommunications Association is focusing on legal, regulatory and government policy issues, while CableLabs looks at the impact of newer services and technologies.

“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

As cable operators and programmers
face rising bills for energy costs,
the Society of Cable Telecommunications
Engineers (SCTE) is moving forward
with drafts of two new standards that could
have signifi cant impact on both energy costs
and the cable industry’s green efforts.

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.
