LONDON, June 9, 2011 -

Cable&Wireless Worldwide has enhanced its smart grid enabling
portfolio with smart grid substation automation products and solutions,
taking the next step towards helping utilities create an intelligent
communications network that will aid in the development of the UK's smart
grid.

Substation automation ensures uninterrupted electric power
flow through several layers of switching, protection & control equipment and
transformers in the electrical generation, transmission, and distribution
system. By monitoring substation operating conditions and performance,
substation automation ensures electricity supply will remain stable. This is
particularly relevant for a smart grid as it will need to accommodate
renewable energy supplies and variable power sources. Substation automation
adds robust data communications to electricity utilities' substation sites,
enabling them to deliver smart grid solutions securely as they seek to
revolutionise the electricity network and maintain security of supply for
consumers and businesses.

C&W Worldwide is facilitating the development of the smart
grid and is the first company in Europe to receive accreditation for Cisco's
Substation Automation Authorized Technology Provider (ATP) Program. As such,
it can deploy Cisco's high-quality, IP-based substation automation products
and solutions to the electrical utility companies in the UK across its own
secure next-generation network.

Paul Brodrick, Utilities Business Development Director at C&W
Worldwide, comments: "A digital communications infrastructure is essential
for establishing an intelligent smart grid, a key component in ensuring the
nation achieves the goals set in the UK Government's Low Carbon Economy. With
substation automation products and solutions running over C&W Worldwide's
secure next-generation network we can create a reliable, secure and scalable
communications network for the smart grid."

C&W Worldwide already has a strong heritage in the utility
sector through the assimilation of Energis, THUS and Your Comms with roots
from National Grid, ScottishPower and United Utilities, giving it in-depth
understanding of the issues faced by electricity suppliers and distributors.
C&W Worldwide has more than 1,100 operational network sites in the UK, many
of them co-located at substations and on the transmission companies'
real-estate and in excess of 20,000 route kilometres of glass fibre, most of
it wrapped around the earth wire of much of the UK's energy transmission
networks.

Brodrick continues: "Substation automation is the next stage
of C&W Worldwide's evolution into smarts. It is already a member of the Cisco
Smart Grid Ecosystem, which aims to facilitate the adoption of Internet
Protocol (IP)-based communications standards for smart grids. Through
relationships such as this we can provide utilities with a compelling suite
of smart grid enabling solutions and a secure next-generation network to
connect it all."
