Norton Rose, Ashurst and CMS Cameron McKenna have landed lead roles on the £260m London listing of a wind farm investment fund.

Greencoat UK Wind, which is believed to be the first listed fund aimed at the UK renewable energy sector, raised the maximum amount through the main market initial public offering (IPO), having initially planned to raise a minimum of £205m.

The proceeds will be put towards acquiring a seed portfolio from energy giants SSE and RWE. SSE has agreed to sell four wind farms to Greencoat for £140m and will invest a further £10m in shares, while Greencoat will also acquire two wind farm sites from RWE.

Norton Rose acted for Greencoat UK Wind with a team led by corporate partner Mike Newell, acting alongside fellow corporate partner Stephen Rigby on acquisition matters and energy partner Andrew Hedges on issues relating to project finance.

Ashurst equity capital markets head Nicholas Holmes represented the banks on the float – Royal Bank of Canada, Barclays and Winterflood Securities – while CMS Cameron McKenna acted for long-standing client RWE with a team headed by corporate partner Charles Currier. SSE relied on its in-house team.

Newell said: "It was a complex deal, as it was challenging to put together an IPO while simultaneously working on the acquisition of the seed portfolios and accommodating both a co-investor and cornerstone investments, which we had to coordinate on a typical IPO timetable.

"As the first IPO of its kind in the sector, many energy companies, as well as investment groups, will be keeping an eye on the project. It's an attractive way of acquiring assets and recycling capital in the sector so I expect we'll see similar deals in this space soon."
