Subtitle: - Contract volume of around USD 10 million - Replacement of
power transformers for prestigious US hydropower project

Au / Wädenswil (euro adhoc) - 15 April 2011 - Swiss industrial
company Von Roll Holding AG has qualified to become the supplier of
numerous power transformers to the Grand Coulee hydropower project.
The project involves manufacturing and delivery of numerous 50MVA 230
kV single phase transformers to electrical and mechanical contractor
company Gardner Zemke. The cooperation will span around 2.5 years
until March 2013. Delivery of the first set of transformer units is
planned for March 2012.

With a capacity of 6,809 MW, Grand Coulee Dam is the biggest
electrical plant in the USA. It is located on the Columbia river,
about 90 miles west of Spokane, Washington, USA. The project involves
the replacement of numerous single-phase, two-winding, 13,6 kV 50MVA
230 kV transformers and appurtenances in the left and right power
plants. The existing transformers are at least 60 years old and have
already experienced several failures. Replacing the infrastructure of
the Grand Coulee Dam is important for a continuous supply of
hydro-electrical power in the Pacific northwest area.

Matthias Oppermann, CEO of Von Roll Holding AG: "We are glad to be
chosen as the supplier of power transformers for such a prestigious
hydropower project. It is an important milestone in Von Roll´s goal
to contribute to the supply of green energy."

The awarding of the contract is based on a trustful business
relationship of Von Roll and Gardner Zemke going back to 2002. The
transformers are sold to contractor Gardener Zemke for the end client
Bureau of Reclamation which is a US-based Federal Electrical Utility.
