Energy: renewable/alternative power in United States

Latham & Watkins LLP

Led from Los Angeles by Jeffrey Greenberg  and able to draw upon a huge pool of resources from other offices on the East and West Coasts, including New York and San Diego, Latham & Watkins LLP's project development and finance practice has an 'excellent perspective of market trends and commercial norms', acting for sponsors, developers and lenders engaged in renewables matters. Although the firm has expertise across all phases of the development and financing of renewable power projects, it adds particular value on later stage mandates and matters requiring complex financing requirements, involving debt throughout the capital structure. Recent highlights include Greenberg's work for MUFG Bank, as lead arranger, on the $1.1bn financing to facilitate the  project financing of multiple geothermal facilities located in Sonoma County and Lake County, California. New York-based tax partner Eli Kazt is also a pivotal member of the team due to the importance of tax incentives for equity investors deploying capital to help fund solar and wind projects throughout the country. New York-based partner Matthew Henegar is appreciated for his ability to structure deals involving complex inter-creditor arrangements, while at a slightly more junior level, San Diego-based partner Omar Nazif is gaining market recognition for his balanced offering on behalf of developers, sponsors and financial institutions engaged in the development and financing of wind, solar, and geothermal energy projects.

Orrick, Herrington & Sutcliffe LLP

Led from San Francisco by Les Sherman and also receiving robust support from the firm's energy and project finance-focused Houston hub, as well as regulatory, environmental and disputes lawyers throughout its national network of offices, Orrick, Herrington & Sutcliffe LLP is well placed to advise a range of stakeholders throughout the life cycle of solar, wind, hydro, geothermal and battery storage projects. The firm has developed deeply entrenched relationships with many developers/sponsors, including the renewable arms of major energy utilities, among which EDF Renewables and E.ON Renewables are the most prominent. Consequently, it picks up a tremendous volume of work as these energy behemoths invest and dispose of a myriad of renewables projects throughout the country, often in the context of large portfolio transactions. Recent highlights included the representation of Acciona Energy in its acquisition of a 3GW utility-scale portfolio of greenfield solar projects and a 1GW battery storage development portfolio from Tenaska. Although his project development and financing expertise in the energy sector covers a mix of renewables assets, Eric Stephens has gained most acclaim for his work within the solar space, particular as it relates to distributed projects, an area that he has been at the forefront since the inception of the technology over a decade ago. Mark Weitzel is particularly noted for his tax equity financing expertise in the solar and wind space. All practitioners named are based in the firm's San Francisco office.

The firm remains the principal adviser to Goldman Sachs on investments made through its renewables fund and has also recently advised the Carlyle Group on the first two investments and financing transactions for its renewable and sustainable energy platform. As a corollary of his broader corporate and M&A practice, the 'proactive and creative' Dallas-based partner Peter Marshall is regularly engaged in private equity-related work in the sector and is a key member of the team, as is Spanish speaking New York-based partner Eamon Nolan, who regularly advises lenders and borrowers on debt and equity financing transactions to fund the acquisition, development, and divestment of renewable assets, both domestically and throughout Latin America. In addition to advising on commercial contracts, including PPAs and joint development agreements, Houston-based partner Danielle Patterson is also regularly engaged in M&A in the sector, adding value by dint of her ability to provide detailed asset-level due diligence.

Fielding dedicated teams of practitioners from across the firm's multi-disciplinary nationwide energy group, Winston & Strawn LLP 'sets the standard for its knowledge of the subject matter and ability to adapt to any scenario' and is consequently able to provide 'thoughtful and constructive' advice to a myriad stakeholders engaged in domestic renewables matters throughout the project life cycle. Much of the work handled by the firm in this space is led from its California offices, which have over the years developed a strong track record advising on solar and wind farm-related project development matters. As well as regularly advising developers on renewable projects, San Francisco-based energy group chair Joe Karp is also praised for his 'in-depth knowledge of what is "market"' in relation to power purchase agreements (PPAs), enabling him to effectively advise both sellers and end-users in relation to power off-take arrangements. Los Angeles-based partner Laurae Rossi is regularly instructed by commercial/regional bank in debt financing related to the development of single projects, as well as in relation to renewables-related portfolio mandates. Mike Pikiel and Richard Shutran co-chair the energy and infrastructure energy group from the firm's New York office, which is also a significant hub for renewables-related transactional work, particularly on the corporate and finance front. Jonathan Birenbaum  handles a great deal of M&A work in the space, for both private equity funds and strategics, including as it relates to the acquisition and sale of existing and development-stage renewable energy assets.

Akin Gump Strauss Hauer & Feld LLP

Akin Gump Strauss Hauer & Feld LLP has a core focus on renewables work for a variety of leading domestic and international stakeholders, including sponsors/developers (SunPower Corporation); lenders (Macquarie Bank, Royal Bank of Canada) and investors (D.E.Shaw Renewable Investments). The scope of the work is broad and includes advising on all aspects associated with the development, financing, acquisition and sale of renewables projects, both from a purely domestic as well as international perspective. Although the firm handles its fair share of volume-based instructions, its work at the leading-edge of the industry, in terms of new technologies, transactions and structures has ensured that it has become the go-to-practice for clients on their more bespoke and innovative transactions. Notable recent highlights include advising SunTrust Bank on its tax equity investment in the Holstein solar project (a 200MW solar project located in Texas), which was notable for being the first tax equity transaction on a solar hedge off-take in the market. The team was, however, impacted in March 2021 by the departure of a number of key practitioners including John Marciano to Allen & Overy LLP.

Allen & Overy LLP

Led from New York by Kent Rowey and aided by practitioners based out of Washington DC, Allen & Overy LLP's 'versatile and responsive' projects, energy, natural resources and infrastructure group regularly handles renewables work for lenders, sponsors, developers and project companies, much of which has an international complexion. Although the firm has capability throughout the project life cycle, it is undoubtedly most well-suited and visible for investors in the latter stage as they look to realize value by taking out developer equity. Much of this M&A-related work is derived from foreign investors, many of which have broader institutional ties established through other international offices at the firm. While at the moment a substantial amount of this work relates to solar projects, the team is well positioned to leverage the firm's strong broader ties with many of the European developers that are expected to dominate deal flow in the burgeoning US offshore wind market. On the financing front, although the firm handles some work for commercial banks, under the guidance of 'exceptional' Spanish speaking Washington DC-based partner Sami Mir, it is particularly accomplished at representing export credit agencies and development banks in Latin American projects. The arrival of a six-partner team from Akin Gump Strauss Hauer & Feld LLP, including Washington DC-based renewables tax guru  John Marciano, as well as Daniel Sinaiko and Matthew Nesburn, who both reside in the firm's nascent Los Angeles office, is a major coup and has the potential to vastly enhance the firm's visibility in the domestic and international market.

I was extremely impressed by Sami Mir’s ability to be on top of everything: drafting, meeting deadlines on turnaround of financing documents, key structuring issues, sound understanding commercial and financial aspects, all this while managing the transaction and a difficult group of lenders and a tough sponsor.’

‘The exceptional Sami Mir is probably the most well-rounded project finance attorney that I have had the pleasure of working with. He is not only excellent at what lawyers are trained to be good at – legal drafting and negotiation – but he also really understands the financial aspects of the deal, which enables him to negotiate even better for the lenders’ benefit.’

Combining both construction and ‘commercially-minded and solutions-oriented‘ industry sector knowledge,exceptional‘ Chicago-based of counsel Sameer Ghaznavi is also a key member of the team, particularly in light of the increasing tendency to implement build-own-transfer contracts in the renewables space.

‘The firm has a deep bench, and in particular has expertise in construction contracts and build-own-transfer structures.’

The team incorporates a flexible and aggressive billing strategy.’

‘The lawyers are accessible and responsive.’

‘The firm’s energy team includes attorneys with a variety of experiences, including those who began their careers at DLA, lateral entries, and, most importantly, attorneys with real in-house experience. DLA’s partners include people who have worked in renewables since its infancy and grown with the industry.’

‘The team provides commercially-minded and solution-oriented execution.’

‘They approach our matters with the right balance of caution and common sense – a combination that is critical in our industry. Additionally, this team is always looking for ways to show initiative, without overstepping their authority. Those characteristics make it easier for my internal attorneys to work with this team, which in turn makes us all more efficient and effective.’

‘DLA is one of the few firms with a full-service renewable energy practice, covering the full variety of transaction structures and construction contracts. There are very few firms that understand the renewable development business and can cover a build-transfer project from start to finish.’

‘Sameer Ghaznavi’s unique combination of thoughtfulness and kindness is what makes him particularly appealing to me. In a world where I am constantly bombarded with the ego of older white male partners in the external counsel world, working with Sameer is a breath of fresh air. I’ve highly recommended him to other in-house attorneys looking for someone who can assist their M&A deals with compassion and brilliance.’

‘Sameer is kind, compassionate, and always puts the deal first. He understands that his job is not just about getting documents drafted and deals done but about making me look good to my executive board and that’s HUGE.’

‘Sameer Ghaznavi is one of the few lawyers who has both construction and transaction experience in the energy space. This is particularly important as the demand for build-own-transfer structures continues to increase.’

‘I very much appreciate Sameer Ghaznavi’s rational, even-headed approach to negotiations and deep experience in energy deals and construction contracts.’

‘Sameer Ghaznavi is an exceptional resource for energy companies. He leverages his prior in-house experience at two energy companies to deliver sensible, real world advice.’

And, long after the financings have closed, Maria is proactive in advising us of changes to the regulatory requirements that our operating renewable projects must comply with and new developments that will have an impact on future Texas financings. She is truly an expert and is never wrong!’
