Private Wires Bill: A Potential Catalyst for Economic Development in Mayo

A new bill currently undergoing scrutiny in the Irish Parliament has the potential to unlock economic development in rural areas like County Mayo. The Private Wires Bill, if enacted, will allow for the construction of privately-owned electricity transmission lines, breaking the current monopoly held by the Electricity Supply Board (ESB).

What are Private Wires?

Currently, the ESB is the sole provider of wires that connect electricity generators to end-users. The Private Wires Bill proposes to allow privately built wires in specific circumstances, opening the door for independent companies and communities to invest in and manage their own electricity infrastructure. This is particularly relevant for renewable energy projects and areas with limited grid access.

Senator Duffy Highlights the Opportunity for Mayo

Fine Gael Senator for Mayo, Mark Duffy, has championed the bill, emphasizing its potential benefits for his county. Speaking after a meeting of the Oireachtas Committee on Climate, Environment and Energy, Senator Duffy stated the bill presents a “great opportunity” to “realise economic development” in Mayo. Midwest Radio reported on his comments.

How Private Wires Can Support Climate Targets

The bill is expected to facilitate the connection of more renewable energy sources to the grid. By allowing private companies to build and operate transmission lines, it can reduce the barriers to entry for renewable energy projects, particularly in areas where the existing grid infrastructure is insufficient. This aligns with Ireland’s climate action goals and its commitment to increasing the share of renewable energy in its energy mix.

Legislative Scrutiny and Next Steps

The Oireachtas Committee on Climate, Environment and Energy is currently conducting pre-legislative scrutiny of the Private Wires Bill. This involves examining the bill in detail, hearing from stakeholders, and proposing amendments before it is put to a vote in the Seanad and Dáil Éireann. Senator Duffy is a member of this committee and actively participating in the process. He also sits on the Committee on Transport. Oireachtas.ie provides details on his committee memberships.

Senator Duffy’s Wider Work on Energy and Transport

Beyond the Private Wires Bill, Senator Duffy has been vocal on energy and transport issues. In October 2025, he raised concerns about the lack of onboard catering on Irish Rail, calling for the National Transport Authority (NTA) to provide clarity on funding requirements for the reinstatement of these services. Fine Gael reported on his advocacy for improved passenger amenities.

On February 26, 2026, Senator Duffy voted against an amendment to a motion on Online Safety. Oireachtas.ie records his voting history.
