Cuxhaven (euro adhoc) - 12. May 2011 - First success for the wind
farm developer, PNE WIND AG, in the United States: With the sale of
its first developed wind farm, PNE WIND USA, a subsidiary company of
Cuxhaven´s PNE WIND AG, has successfully broken into the US wind
market. The purchaser of the 20 MW wind farm in Belle Fourche, South
Dakota, will be Black Hills Power, a utility subsidiary of the
American energy company, Black Hills Corporation, dependent on a
favourable ruling from the South Dakota Public Utilities Commission.

"The high quality of the project development work was a convincing
argument for the customer. Considering the current difficulties for
renewable energies in the US market, the sale of this construction
ready wind farm is a great success," said Roland Stanze, the
president of PNE WIND USA.

The project was developed by PNE WIND USA and its joint venture
partner, Renewable Solutions. "Our wind farm will produce valuable
economic development for the region while providing Black Hills Power
with a cost effective source of power generation for the next 30
years," said project developer Mark Eilers, president of Renewable
Solutions. It is the first wind farm in western South Dakota and
advances Black Hills Power´s progress toward the state´s renewable
objective that 10 percent of all electricity sold be obtained from
renewable, recycled and conserved energy resources by 2015. Black
Hills Power has filed a request for a declaratory ruling from the
South Dakota Public Utilities Commission. If Black Hills Power
receives a favourable ruling, all remaining permits will be obtained,
and the wind project will be constructed by Black Hills Power in
Butte County, north of Belle Fourche, with commercial operation
expected before Dec. 31, 2012.

"As a community partner since 1883, Black Hills Power is committed to
providing our service areas with the power needed to grow and develop
at reasonable rates. This project offers a cost effective way to
diversify our generation resources by adding wind energy that will
support good public policy and the economic development of the Black
Hills region," said Chuck Loomis, Vice President of Electric
Operations for Black Hills Power.

"We are proud to support the people of western South Dakota in the
development of this wind power project. Working with the extremely
talented people from Black Hills Power has helped us to see this
project through," said Kelly Lloyd, general manager for PNE WIND USA.
Martin Billhardt, CEO of PNE WIND AG adds: "The United States and
Canada are very attractive markets for us. Currently, we are
developing about 30 additional projects in North America and have
already secured 33,428 acres of land which enables us to continue our
project pipeline expansion in this region."
