When it comes to structuring and closing groundbreaking transactions in the new energy economy, Wilson Sonsini Goodrich & Rosati has become the firm of choice for leading companies, investors, and lenders.

No other law firm combines more than 50 years of undisputed leadership in technology and business model innovation with a sophisticated, experienced energy project development and finance practice. This combination makes us exceptionally well suited to serve as a strategic advisor to innovative companies at all stages of development, and enables us to provide top-tier legal counsel in everything from patents to project finance, and government affairs to tax structures. Further, WSGR is often involved in first-of-their-kind projects, financings, and transactions—deals that are fundamentally changing the ways people power their homes and factories, fuel their vehicles, and manufacture the next generation of plastics and chemicals.

Our Integrated, Multidisciplinary Team

WSGR has a fully integrated team of attorneys with industry-relevant, practical experience that ranges from securing venture financing and protecting intellectual property for clean energy start-ups to developing and financing large-scale energy and infrastructure projects around the world. For each assignment, and depending on client needs, we assemble the right personnel and expertise, offering our clients the advantages of working with a collaborative, coordinated team that maintains a commercial-minded focus on the needs of project participants.

When we work with early-stage clean energy companies, our approach is guided by the firm's 50-plus-year history of helping innovative, disruptive companies grow. For project development and project finance clients, we take a commercial-minded, practical approach focused on meeting the varied needs of project participants. For project investors, banks, and other lenders, in addition to delivering substantial value through our energy market and infrastructure finance expertise, our attorneys are known for their innovative and influential approach to deals, and for completing several first-of-their-kind transactions. In fact, another quality that sets our attorneys apart is our long-standing relationships with venture capitalists, private equity firms, and major financial institutions across the U.S. and abroad, which allow us to serve as a conduit to—and advisor regarding—a wide variety of funding sources.

Regardless of the type of client we're representing, our aim is to create alignment between both concurring and conflicting interests, and to help clear the way so deals get done. This point is best illustrated by the growing number of venture financings, megawatts, purchase power agreements, and other closed transactions associated with WSGR.

When we describe our team as "multidisciplinary," it means that in addition to each attorney's energy sector expertise, we bring together the skills and resources clients need to pursue and achieve desired results. More importantly, it means we can assist clients across all project phases, from development and financing to expansion or renewal options.
