Perigus Energy names Tom O'Brien as independent chair four months after CIP acquisition

Perigus Energy has appointed Tom O'Brien as independent chair and non-executive director, the Cork-headquartered onshore renewables company announced, alongside two further senior management changes^[1].

O'Brien's background

O'Brien retired from Brookfield Asset Management at the end of March 2025 and has since worked as a senior adviser and consultant^[1]. His appointment gives Perigus a chair with direct experience of large-scale infrastructure investment at a moment when the company is building out its post-acquisition governance structure.

Two further appointments

Alongside O'Brien, the company confirmed two internal and external management moves^[1]:

• Eamonn Boland has been promoted to chief commercial officer
• Declan McCarthy joins as chief financial officer
• Both Boland and McCarthy will be based at Perigus Energy's Cork headquarters

Company context

Perigus Energy was acquired in May 2026 by Copenhagen Infrastructure Partners from Ørsted in a deal valued at €1.44 billion^[1]. The company operates across Ireland, Germany, the United Kingdom and Spain, with 668 MW of operational renewable capacity and three further projects under construction in Ireland and Germany, giving a total operational and under-construction portfolio of 826 MW^[1].

The governance build-out follows a pattern common to CIP-backed platforms: the fund tends to install independent board-level oversight relatively quickly after closing, before accelerating development-stage capital deployment. Perigus has a multi-gigawatt pipeline across its four markets, spanning onshore wind, solar and battery storage.

Watch for how the new CFO shapes the company's project financing approach - CIP's other European platforms have leaned heavily on project-level debt - and whether the CCO appointment signals an intent to expand the company's PPA book ahead of further construction starts.
