Wärtsilä to deliver 25 MWe gas power plant to...

Wärtsilä Corporation, Press Release, 13 August 2008

Wärtsilä North America, Inc., a subsidiary of Wärtsilä Corporation
and a leading provider of power plants for flexible power generation,
has been awarded an engineered equipment supply contract by GEUS, a
municipally-owned electric power, cable and high speed Internet
system located in Greenville, Texas, USA.

This is Wärtsilä's first power plant order for a municipally-owned
utility in the state of Texas. The contract for the 25 MWe gas-fired
power plant is valued at over 19 million USD. The plant will help
provide power to the 26,000 consumers in Greenville and the
surrounding area served by GEUS, as well as help to meet their 113 MW
peak demand. It will also be dispatched to meet ERCOT's (Electric
Reliability Council of Texas) requirements.

The power plant, to be called "Greenville Engine Plant" will operate
on pipeline quality natural gas and feature three Wärtsilä 20V34SG
engines, along with mechanical, electrical and control auxiliaries,
switchgear and exhaust emission controls. Additionally, Wärtsilä will
provide installation and commissioning support, as well as factory
training.

"Wärtsilä was chosen due to the efficiency of their engines and fast
start capability which will allow GEUS to self-provide energy during
intervals of high market prices," said David McCalla, GEUS General
Manager. "This addition to our resource portfolio supports GEUS'
mission of providing the most economical, reliable power available to
the Greenville, Texas community," McCalla added.

"Wärtsilä is delighted to be working with Mr. McCalla and his team at
GEUS, the first municipally-owned electric utility in Texas, for this
new flexible power plant", says Wayne Elmore, Business Development
Manager for Wärtsilä in North America. "This much needed project will
provide clean, high efficiency peaking and fast response power to
Greenville and the ERCOT market."

The plant will be connected to the local utility's grid and located
on an existing power plant site in Greenville, Texas, which is about
50 miles northeast of the Dallas-Fort Worth Metroplex. The equipment
is expected to arrive at the site in August of 2010, with the entire
plant entering commercial operation in the fourth quarter of 2010.

Wärtsilä's flexible power plants - a superior alternative

Wärtsilä's flexible power plants features include the ability to
reach full plant output in eight minutes, provide 25 percent power in
two minutes, the highest simple cycle efficiency available in the
industry, constant performance over varying ambient conditions, low
lifecycle costs, small unit sizes and rapid response to varying grid
conditions.

Wärtsilä's natural gas fueled technology has the capability to
operate efficiently at low loads. This feature not only translates
into lower electricity costs for GEUS' consumer/owners, but it also
increases the number of megawatts of "non-spinning reserve" available
to the ERCOT grid, thereby increasing the value of the plant.
Additionally, Wärtsilä's flexible power plants are able to supply all
commercially traded ancillary services, including black start
capabilities.

Wärtsilä's flexible power plants also allow customers to meet today's
increasingly stringent air quality requirements. Furthermore, by
employing a closed loop cooling system, Wärtsilä's engines do not
consume process water or require significant wastewater treatment or
disposal. This helps to address the growing concern over water supply
in many areas of the US.
