Second Wind Demonstrates Remote Sensing Technology to Key Players in the South African Wind Power Market

SOMERVILLE, Massachusetts and CAPE TOWN, South Africa, March 8, 2011 - Wind measurement technology developer Second Wind and wind consultancy
firm Wind Prospect raised awareness of the Triton Sonic Wind Profiler in a
steadily growing wind energy market with a demonstration of remote wind
sensing last week in South Africa.

The event in Cape Town, South Africa drew wind power developers,
researchers, technologists and financiers. Second Wind conducted a live
demonstration of Triton's remote sensing capabilities that included
displaying real-time wind measurements with Second Wind's SkyServe web-based
wind data service. Attendees were impressed with Triton's accuracy and the
ease of setting it up - just over an hour from unloading it on the
demonstration site to delivering data.

Said one attendee, "It was instructive to learn the risk management role
Second Wind's instruments play in the financing of projects. I found the way
the company set up the remote data capture and monitoring to be an excellent
quality management approach. The improvement the instrument provides over
data from met masts is significant."

Triton is an advanced remote sensing system that uses sodar (sound
detection and ranging) technology to measure wind in the areas that most
affect a wind turbine's performance. By measuring wind speeds at the turbine
rotor's hub height and beyond, Triton reduces uncertainty in annual energy
production (AEP) forecasts. Easy to install and capable of autonomous
operation, Tritons are being used throughout the wind industry, alone or in
conjunction with met towers, to streamline the wind farm development process
and to improve wind farm operations.

"There is a lot of potential for Triton to make a big impact in the South
African wind energy market," said Chanda Kapande, Business Development
Manager of Wind Prospect Africa. "Triton's combination of accuracy, economy
and portability make it a versatile solution for collecting data and making
decisions quickly. That's a valuable asset from early in the development
process right through to operation."

Second Wind's presence in the South African market has grown steadily
since the first Tritons were installed there in June 2010. Since then, Second
Wind has taken orders for five more Tritons, including several repeat orders
from international wind developer Windlab. South Africa's wind resources are
estimated by SAWEA (South African Wind Energy Association) to exceed 30GW by
2025. Several of the world's leading wind turbine OEMs, project developers
and service providers have already established a presence in South Africa.
