Visión general
Mayer Brown’s Renewable Energy practice brings together a dedicated team of lawyers with deep experience across the spectrum of the industry. Our team advises clients on all legal aspects of renewable energy transactions—from greenfield project development and finance to the purchase and sale of large companies and operating portfolios to restructuring arrangements in distressed situations. Our team stands at the forefront of the energy transition movement.
Our clients include many of the largest financial institutions, sponsors, and funds actively working on renewable energy and energy transition opportunities in the US and across the globe. Our deal list—a sampling of which can be found below—demonstrates that we have earned and maintain the trust of the most sophisticated actors in this constantly evolving space.
Because of our abilities, our team has become a go-to firm for an incredibly wide range of technologies—onshore wind, offshore wind, utility scale and distributed solar energy, battery storage, fuel cell, geothermal, nuclear, carbon capture, and biomass to name a few. Similarly, there is not a transaction structure for which the team does not have a deal list and cadre of dedicated lawyers—debt financing of all kinds, tax equity financing, mergers and acquisition work, and securitization among them.
“Their expertise encompasses not only a profound understanding of the financing structures that underpin renewable energy projects but they also are commercially-minded and responsive to client needs.”
“Mayer Brown’s team is exceptionally commercial in real-time decision-making scenarios. The team is confident and able to effectively assist in determining legal hurdles in any given situation.”
