Energy transactions: conventional power in United States

Baker Botts L.L.P.

Combining 'deep energy industry knowledge' with regulatory and transactional (including M&A, finance and restructuring) expertise, Baker Botts L.L.P. provides a strong service to clients throughout the life cycle of a broad range of power-related projects, including renewables, conventional generation, transmission, battery storage, and LNG-to-power. Praised for her 'exceptional client service' and 'deep sophistication, spanning multi-faceted practice areas', Washington DC-based partner Elaine Walsh regularly takes the lead on the team's most significant transactional work in the power space for a balanced array of stakeholders, including utilities, Independent Power Producers (IPPs), developers, and funds. M&A transactions account for a sizeable proportion of Walsh's deal flow in the power sector, for both financial sponsors, as well as large energy companies, including NRG Energy, a client which she continues to advise on a range of matters, including as it relates to its investments (and disposals) in gas and coal-fired generation facilities throughout the country. New York-based partner Martin Toulouse is also a vital resource to sponsors and corporate borrowers seeking the necessary financing arrangements to facilitate new money deals and restructurings in the sector. Toulouse recently advised NRG on the financing (which involved the issuance of sustainability-linked notes) to fund its $3.6bn acquisition of Direct Energy, a North American subsidiary of Centrica. Austin-based partner Courtney Fore continues to develop a strong corporate and securities practice in the power sector, and regularly advises energy companies and private equity investors on M&A, as well as issuers on their debt and equity capital raising activities. Although he is perhaps better known for his renewables prowess, New York-based partner Michael Didriksen handles a not inconsiderable amount of M&A and project development matters in the conventional power space, and co-heads the firm's overarching power sector offering alongside Walsh.

On the project finance side, Los Angeles-based partner Jeffrey Greenberg is regularly engaged in the development, finance, sale and acquisition of single projects in the conventional power space, while New York-based partner Eli Katz, who is global vice chair of the energy and infrastructure group, excels at tax equity financings within the renewables space, in particular.

Gibson, Dunn & Crutcher LLP

Co-headed from New York by Peter Hanlon and Nicholas Politan, and aided by a strong regulatory offering out of Washington DC, Gibson, Dunn & Crutcher LLP's power and renewables group has, over recent years, developed a particularly strong reputation advising strategic and financial investors on big-ticket M&A transactions across the generation, transmission and distribution value chain.

Hanlon takes the lead on much of Berkshire Hathaway's energy transactions, including its recent high-profile $9.7bn acquisition of Dominion Energy's natural gas transmission and storage business.
