Energy Disputes

The political and economic volatility in the energy sector has resulted in complex, high-value disputes across a range of jurisdictions.

The increasing incidence of state intervention, coupled with more intense competition for resources and stronger regulation, has contributed to a rise in contentious matters.

We have advised on many of the most high profile cases in this area, managing effectively and efficiently numerous disputes where hundreds of millions, sometimes billions, of dollars are at stake. These cases are typified by significant volumes of documentation and complex, disputed facts. We have an outstanding record of assisting our clients in avoiding or resolving disputes and regulatory issues through negotiation, mediation, international arbitration, litigation, expert determination and other forms of alternative dispute resolution. As well as multinational corporations active in the energy sector, we regularly advise states and international organisations on disputes in this sector.

We are, in particular, recognised as market leaders and innovators in relation to disputes arising under the Energy Charter Treaty in relation to cross-border energy investments. Having brought the first-ever claim under that Treaty in 2000, we are currently acting on the first collective proceeding under it, as well as representing clients on a number of other claims in the renewable energy sector.

Our gas price disputes practice is second to none. In 2014, Global Co-Head of International Arbitration Mark Levy QC edited the first book on the subject, Gas Price Arbitrations: A Practical Handbook. The second edition, co-edited by Mark and London arbitration partner James Freeman, was published in November 2019.
