Energy is one of the most important and fast changing industrial sectors.

The need to reduce greenhouse gas emissions, growing global demand, security of supply and ageing energy assets mean that governments and energy companies globally are faced with some of the most complex and challenging decisions that will have an impact not only on economic prosperity, but also on the long-term health of the environment.

All these factors make this an exciting industry to work in, and one that requires its advisers to have sector–specific knowledge backed up by a global resource capability.

Allen & Overy's global Energy team is at the forefront of this sector, providing clients with advice on matters relating to power and utilities (including IWPPs), transmission and distribution, carbon capture and storage, oil & gas (up, mid and downstream and LNG) and climate change.

Allen & Overy provides pioneering advice on the entire lifecycle of these assets, from the consenting and planning process, through to the construction, financing, operation, maintenance and ultimately their refinancing or sale. We advise sellers and acquirers (on M&A transactions), project sponsors, corporates, financial/passive investors, suppliers, manufacturers, governments and debt funders (including banks, bond arrangers, ECAs, DFIs and multilaterals) on energy transactions globally. These transactions are supported by our specialists in areas such as environmental, regulatory, antitrust, tax, employment and planning law.

The energy market is global, with many deals crossing borders. Allen & Overy is one of the few firms that can leverage a truly global network and deliver an absolutely seamless service across the UK, Europe, CIS, the Middle East, Africa, Asia Pacific, Australia, the United States and Latin America. Our global exposure and experience is highly valued by our clients.
