Peter Østergaard Nielsen specialises in offshore wind energy

After completing his legal studies at the University of Copenhagen, Peter Østergaard Nielsen joined Bech-Bruun where he received extensive training in competition and public procurement procedures and processes. He then joined Plesner as a lawyer to participate in a significant number of M&A deals, thus broadening his understanding of the aspects of the drivers behind business dealings.

Following his period with Plesner, Peter joined the fast growing legal department of DONG Energy A/S (now Ørsted) where he became Head of Legal Sourcing & Strategic Contracts, embarking on his first real venture into the offshore wind industry. The legal department, of which he had become Head of Sourcing and Strategic Contracts, was about to conclude a multitude of large offshore wind deals, for which Peter was to negotiate and execute the contractual basis.

Peter drafted and negotiated the key contracts for more than 10 offshore wind projects in Denmark, UK, Germany, Poland and France and was involved in the most cutting-edge offshore wind developments, including the drafting and negotiation of the first framework agreements with Siemens, introducing the 3.6 MW and – following that – the 6 MW platforms. Subsequently, DONG and Peter ventured into unknown lands embarking on negotiations with MHI Vestas which was making a strong entrance to the offshore wind market, and Peter negotiated the first commercial contract for the MHI Vestas 8 MW platform.

With these groundbreaking agreements, Peter has developed creative and innovative solutions to set up the correct risk split between the supplier and the developer, and, in 2012, he was appointed acting Head of Cost of Energy at DONG Energy Wind Power, a position that included the responsibilities of a lead negotiator.

From his time with DONG – and, subsequently, throughout his career in the private sector – Peter has been known for his improvement of risk-sharing models, optimisation of wind-farm operating processes and supplier interfaces, split of technical risks, “up-side sharing” mechanisms, and mechanisms for the protection against the impact of new technology and models that support structures in support regimes.

As a practicing lawyer, Peter continues to counsel project owners and investors and acts as a lead legal advisor and negotiator for multiple contractors, including MHI Vestas, Bladt, NKT Cables, enhancing his extensive knowledge of the employer's perspective of the offshore wind business. As it is, Peter is quite capable of acting on behalf of both employers and contractors, which allows Peter and his team to maintain and improve their unique understanding of current market terms.
