Irish renewable energy company BnM has signed an Electrical Balance of Plant (EBoP) contract with H&MV Engineering for the development of Oweninny Wind Farm Phase 3 in North Mayo, marking a significant advance in the delivery of one of Ireland's largest onshore wind projects.

As reported by Irish Building, the EBoP scope covers the full suite of electrical infrastructure required to connect the wind farm to the national grid, including substations, transformers, switchgear, cabling, and control systems essential for secure and reliable energy transmission.

Oweninny Phase 3 will comprise 18 turbines with a projected output of approximately 100MW, alongside a new 110kV substation and underground grid cable linking the development to the transmission system at the existing Bellacorick substation. The project follows Phase 1, commissioned in 2019, and Phase 2, commissioned in 2023, extending a wind energy development that has progressively built out BnM's renewable capacity in the west of Ireland.

John Reilly, Head of Renewables at BnM, said: "This is an important milestone in the delivery of Oweninny Wind Farm Phase 3 and in BnM's ambition to build a 5GW pipeline of sustainable energy systems — including wind, solar and biomass projects. Our focus is on enabling industrial and economic growth while safeguarding our environment for generations to come."

H&MV Engineering, a global high-voltage electrical engineering firm with over 14GW of projects in design and construction and 1,750 employees across 19 international offices, brings significant grid infrastructure expertise to the project.

BnM, formerly Bord na Móna, has been serving Irish communities for over 90 years and is currently building a 5GW pipeline of sustainable energy systems across wind, solar, and biomass.
