Renewables and Clean Technology

With the reduction of carbon emissions and the assurance of energy security so high on the agenda for governments and energy companies, renewable energy (on and off shore wind, solar, hydro and marine power) is as an essential part of the solution for slowing the pace of climate change and improving energy security.

Ambitious carbon reduction targets being set globally and regionally means that many governments are incentivising the development of renewables through support programmes, such as feed-in tariffs, which are having a positive impact on the pace of development of renewables. All of 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.

In light of this, supporting the energy industry, in particular renewables, is a key priority for Allen & Overy, and our Energy Group focus allows us to help foster and share industry knowledge and expertise both across our numerous offices and across all our legal disciplines. Our in-depth understanding of renewable energy and the wider energy sector ensures we are able to use existing know-how and add value at the point of instruction with little or no learning curve. Innovative solutions developed for projects in one jurisdiction can be applied to similar projects elsewhere, and that plays to our global network.

We provide our clients with 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 are at the forefront of the renewable energy market, advising debt funders (including banks, bond arrangers, ECAs, DFIs and multilaterals), sellers and acquirers (on M&A transactions), sponsors, corporates (including large vertically integrated utilities), suppliers, manufacturers and governments on market leading projects and transactions globally. These transactions are supported by our specialists in areas such as environmental law, regulatory, tax and planning.
