Ørsted — M&A Activity 2015

Aug 21, 2015

Today, DONG Energy acquired the Hornsea zone and the project rights to Hornsea
Project Two and Three, which have the potential of 3 gigawatts (GW) offshore
wind capacity. This follows DONG Energy’s acquisition of Hornsea Project One, a
1,200 megawatt (MW) offshore wind project in the Round 3, which was announced
in February 2015.

The Hornsea zone projects form one of the world’s biggest offshore development
zones. The acquired Hornsea Zone Projects Two and Three are expected to form an
important part of DONG Energy’s post 2020 project pipeline.

Samuel Leupold, Executive Vice President in DONG Energy said:
“We have already invested around £6 billion in the UK, and the Hornsea Zone
provides us with new exciting development opportunities, not least because of
the sheer size of the project in terms of acreage as well as the high
generation potential. This will help us in our committed efforts to reduce
costs of electricity and maintaining our position as global leader in offshore
wind beyond 2020.”

Leupold added: “Today’s announcement underlines our strong commitment to
helping the UK deliver low carbon energy supplies while creating jobs and
building a strong local supply chain.”

DONG Energy is acquiring the Hornsea Zone from Mainstream Renewable Power and
Siemens Financial Services. Following the takeover, DONG Energy will, as the
sole owner, assume responsibility as lead developer of the whole Hornsea Zone.

The Hornsea Zone is located between 31 and 190 km off the Yorkshire coast and
covers more than 4,000 square kilometres.

The information provided in this announcement does not change DONG Energy’s
previous financial guidance for the 2015 financial year or the announced
expected investment level for 2015-2016.
