“ The corporate team in Matheson is excellent. Very responsive, thorough, excellent negotiators and deliver advice on complex topics in a pragmatic and workable way. ”

Commercial, Corporate and M&A: The Legal 500 2023

Matheson has the largest M&A group in Ireland with a team of dedicated lawyers focused on energy and infrastructure (E&I) transactions who are supported by E&I specialists within the real estate, tax, environmental and planning, banking and finance teams.

Our group is the largest E&I practice (transactional, project development and regulatory) in the Irish market, which complements our market-leading M&A practice, which is consistently mandated on the most high-profile, complex and high value transactions in both the domestic and cross border markets.

Our firm has advised on a broad range of E&I transactions including portfolio, single asset and company sales, asset auctions, mergers and joint ventures, strategic alliances, corporate and project financings. Our E&I M&A team advises the largest sponsors and PE, infrastructure, pension and insurance funds on their investments and acquisitions in the Irish E&I sector and also represents a broad array of public and private companies, public bodies / semi-States, regulators, developers, contractors, investors and lender teams.

We counsel clients on the unique opportunities and challenges presented by large-scale infrastructure, energy and construction projects and transactions, with specialised experience in permitting, contract negotiation, risk allocation, development structuring, project and acquisition financing, transactional matters, corporate law and governance matters and day to day operational and regulatory advice.

Our E&I M&A team continues to advise on the most high profile, complex and transformational transactions in the Irish E&I sector, including advising a number of Irish utilities on their joint venture partnerships for the co-development of off-shore wind projects, Copenhagen Infrastructure Partners on its acquisition of a majority stake in Elgin Energy (a portfolio of 15 GW of solar PV and battery projects), Hanwha Energy Corporation on the sale of its majority stake in the largest battery energy storage system project in Ireland (and one of the largest such installations in Europe) and Cellnex on the sale of its Irish business (Ireland’s largest telecoms tower company).

In recent years, Matheson has advised sponsors and lenders on over 2GW of renewable and conventional power plant developments, including over 1GW of onshore wind farm developments.
