Size of VRB-ESS for Sorne Hill Increased to 2MW X 6hr and Completion of Sustainable Energy Ireland / Tapbury Feasibility Study

Vancouver, Canada (ots/PRNewswire) - VRB Power Systems Inc.
(TSX-V: VRB) announces that the VRB-ESS(TM) being sold to Tapbury
Management Limited ("Tapbury") for Phase II of the Sorne Hill Wind
Farm in County Donegal, Ireland ("Sorne Hill") has been increased in
size from a 1.5MW x 8hr system to a 2MW x 6hr system

The value of this contract to VRB Power has increased from US$6.3
million to approximately US$9.4 million. The agreement remains
subject to execution of final contracts between Tapbury and VRB Power

The re-sizing of this system follows completion of the independent
feasibility study on the implementation of the VRB-ESS at Sorne Hill
jointly commissioned by Sustainable Energy Ireland (SEI) and Tapbury.
This study validates a number of the key revenue streams that will be
generated by the VRB-ESS. It also concludes that the optimum size of
the system is 2MW of power with 6 hours of storage and the ability to
provide 3MW of pulse power for 10 minute periods every hour in order
to deal with short term volatility in wind generation

The study focuses on wind generation at Sorne, and also shows the
potential for storage across Ireland with respect to the planned roll
out of wind power and Ireland's Kyoto commitments. A summary of the
study has been published on SEI's web site (www.sei.ie) and is also
available on VRB Power's web site (www.vrbpower.com) under the "VRB
News" section.

"Wind energy is one of Ireland's largest accessible renewable
energy resources," said David Taylor CEO of Sustainable Energy
Ireland. "In the recent Energy White Paper, the Irish Government set
a target to deliver 33% of electricity from renewable sources by
2020, a significant proportion of which will be provided by wind.
Integrating large amounts of wind power presents many challenges with
regard to grid upgrade costs, power quality and of course
intermittency management. Through its funding of this study, SEI is
therefore pleased to be supporting activities which will enhance the
understanding and market uptake of these energy storage technologies
and which will help us to realise the full potential of wind energy
in Ireland."

"We are delighted with the findings of this study," stated John
Ward, Director of Tapbury. "The report provides technical and
economic validation for a number of the key revenue streams that we
had previously identified for the planned implementation of the
VRB-ESS at Sorne Hill. The increase in the size of the system enables
us to maximize these revenue streams and, when combined with
additional market based payments, shown in the Grant Thornton report
included in the study, provides a strong economic case for this
purchase. In particular, the study demonstrates the potential for
purchasers of VRB Energy Storage Systems in the Irish market to
achieve a very healthy IRR of 17.5% on their investment."

"This study now provides us with the data and validation required
to finalize our off-take and other revenue agreements for Sorne Hill.
This will in turn enable us to complete our project finance
requirements and execute final contracts with VRB Power Systems,"
concluded Ward.

"This study demonstrates the economic viability of our systems for
wind farms such as Sorne Hill," stated Tim Hennessy, CEO of VRB Power
Systems. "This is largely due to our ability to enable wind powered
generation to match many of the characteristics of conventional 'base
load and peaking plant', thereby allowing wind power to be dispatched
in a similar way to conventional generation. The report also
highlights the need for storage in Ireland to enable the successful
roll-out of wind generation from the current installed base of
approx. 800MW up to and beyond the 3,000MW currently contracted or
proposed, and to deal with the intermittency and constraint issues
already being experienced. It is estimated that at least 700MW of
storage may be required across Ireland. This sale will provide us
with a "blue-print" to execute on similar opportunities in Ireland
and worldwide," concluded Hennessy.

About VRB Power

Headquartered in Vancouver, Canada, VRB Power Systems Inc. is an
energy storage technology developer which is marketing, selling and
manufacturing products utilizing the patented VRB Energy Storage
System ("VRB-ESS(TM)"). The VRB-ESS can economically store and supply
large amounts of electricity on demand and is focused on stationary
applications. It is a long life, cost effective, low maintenance,
efficient technology that allows for the scalability of power and
storage capacity independently. The VRB-ESS is particularly
beneficial to renewable energy providers, utilities and end users
through its ability to "inventory" electricity, allowing for the
optimal match of supply and demand.

The VRB-ESS is well suited for a variety of applications. Enabling
the provision of "firm" capacity from intermittent renewable
generation such as wind and solar; more cost effective and efficient
generation of electricity in remote areas; capital deferral for
utilities; and load levelling (peak shaving) applications. The
VRB-ESS is also capable of providing backup power solutions including
applications for utility sub-stations and telecommunication sites.
The VRB-ESS is characterized by having the lowest ecological impact
of all energy storage technologies and is unlike most other
conventional energy storage systems that rely on substances such as
lead or cadmium.
