Sustainable Energy Technologies (TSX VENTURE:STG), ("Sustainable Energy" or the
"Company"), a manufacturer of intelligent power electronics for decentralized
generation and storage systems, is pleased to report that a New York based
contractor has selected the Company's Bidirex energy storage inverter for a US
Army contract to demonstrate a new Intelligent Scalable Micro-Grid solution.

First deliveries are planned for this month. The identity of the contractor is
not disclosed due to confidentiality obligations and for competitive reasons.

"A micro-grid is an autonomous power supply system that delivers firm, grid
quality power to isolated or critical loads from local generation sources," said
Brent Harris, CTO of Sustainable Energy. ""AC coupled" micro-grids are gaining
ground quickly as the next generation off-grid system due to their flexible,
modular design, with the military taking a leading role in deployment and

"Our patented Bidirex energy storage inverter enables the highly flexible "AC
coupled" design with the power industry's highest round trip conversion
efficiencies. Its unique open control easily accommodates emerging low voltage
battery technologies and greatly facilitates system design." 

"Customer up-take to date indicates that a significant portion of North American
market for distributed energy storage in the next few years will come for remote
industrial (telecommunications, oil and gas, mining) and military applications."

"Inverter-controlled, battery centric micro-grids, using alternative energy
sources, are often able to deliver more resilient power at a lower cost than
diesel generators that have been traditionally used in these applications,"
Harris added.

About Sustainable Energy 

Sustainable Energy ( designs and manufactures advanced
power electronics for distributed smart grid and micro-grid applications.
Advanced power electronics are a critical interface between all distributed
generation and storage systems devices, ensuring the delivery of high quality
alternating current (AC) to the power grid as well as providing utility control
over the interconnection and power quality.

Sustainable Energy's bi-directional low voltage energy storage inverter branded
Bidirex directly connects low voltage batteries to smart grids and micro-grids
with the power industry's highest round trip (battery charging and discharging)
efficiencies. The inverter meets tough utility smart grid standards, such as
Germany's VDE 4105, which is becoming a global standard and enables full utility
control over the battery dispatch and power quality functions. 

Sustainable Energy's platform is based on patented breakthroughs in power
inverter design that enable its platform to convert high current/low voltage DC
into high quality AC with conversion efficiencies that are higher than anything
in the market with an inherently lower cost structure.
