Hello everyone. I thought this information would be of interest to
you all. Enjoy.

Powercorp announces the first use of its world leading Powerstore
technology on a wind/diesel grid in Australia.

The project at Coral Bay in Western Australia will see the
installation of three cyclone proof 275kW Vergnet wind turbines, a
500kVA Powerstore unit and a diesel power station consisting of
eight 320kVA Low Load Diesels.

Powercorp is supplying the Powerstore unit, the eight 320kVA low
load diesel units, the power station switchboard and the control
system to run this complex project. The balance of power station
plant including the wind farm is being installed by Verve Energy,
who will own and run the facility.

It is expected that this combination will supply over 50% of the
energy for Coral Bay from the wind, significantly reducing the
environmental affects from the power station. Commissioning is due
in April 2007.

Powercorp and Verve Energy have worked closely with Horizon Power to
design a wind/diesel solution for Coral Bay that met the very tight
reliability and quality of supply standards required. This involved
aspects of modelling, re-design and algorithm development for the
wind/diesel product.

It also meant the use of specialised wind turbines from Vergnet,
which are lightweight two-bladed downwind machines suitable for
cyclone prone areas such as Coral Bay. Being light, induction type
turbines with incredibly fast rotor responses the Powerstore unit is
required to ensure system stability at the very high penetrations
expected on this system, including days on end with over 95% wind.

Powercorp and Verve Energy have worked closely over many years to
develop world leading wind/diesel technology, having completed
projects at Denham, Hopetoun, Esperance, Bremer Bay and Rottnest
Island together using inverter coupled turbines. Most of these
systems have benefited from the use of Low Load Diesels, a product
developed by Powercorp and marketed by Diesel & Wind Systems.

The Coral Bay project will see the fourth commercially installed
PowerStore worldwide and the second in Australia. The first
PowerStore installed in Australia was at the BHP Billiton owned
Leinster Nickel Operation, where it is operating in peak lopping
mode.
