CRU Network Charge Review: What It Means for Irish Homes

Electricity network charges in Ireland are being reviewed for the first time since 2000, and the CRU closed Phase 1 of its consultation on 22 October 2026. Network charges make up about 25% of a typical domestic electricity bill, so any change to how they are structured affects every Irish home, including households with solar panels, batteries and electric cars. This is a review of how grid costs are shared out between users, not a change to the total cost of the network.

What Is the CRU Reviewing?

The Commission for Regulation of Utilities has restarted its Electricity Network Tariff Structure Review (ENTSR) and published a Phase 1 consultation covering the objectives, principles, scope and high-level design of electricity network tariffs. The CRU consultation paper sets out why the framework needs to change: electrification of heat and transport, rising demand from electric vehicles, heat pumps and large energy users, more renewable generation, and heavy planned investment in the grid.

The essentials:

• Network charges recover the cost of building, maintaining and operating the transmission and distribution networks.
• They account for roughly 25% of a typical domestic electricity bill.
• The review does not change how much the network costs in total, which is set through the separate price review process.
• Phase 1 examines structure and principles. Detailed tariff options and impact assessments are for later phases.

Why Does the Structure of Electricity Network Charges Matter?

Because the structure decides what you pay for the grid, no matter how much electricity you import.

Most domestic network costs are currently recovered through unit rates, which means a household that imports less, because it has solar and a battery, contributes less towards the network. A redesigned structure could recover more through fixed or capacity-based charges, or lean harder on time-of-use signals that reward using the grid at quieter times.

What Should Homeowners Do Now?

Nothing on your bill changes today, and the timetable is measured in phases rather than weeks. The direction of travel still matters when you are planning a system.

• If you are installing solar panels, design for self-consumption, because a unit you use at home is worth far more than a unit you export. Our solar panel guide covers sizing.
• If you are adding a battery, the €600 SEAI battery grant (value correct at October 2026) and the removal of grid charges on home batteries from 1 October 2026 both improve the case. See our home battery storage page.
• If you drive an EV, charge overnight on a night or smart tariff, which is exactly where time-based signals reward you. Our EV charger range includes smart units that schedule charging.
• If you already have solar, check how network charges appear on your bill so you can see what a restructure would touch. Our electricity bill breakdown explains each line.

What Happens Next?

The CRU has said that detailed tariff design options and impact assessments will be consulted on in later phases, and that it intends to progress the review at pace. In practice, no household will move to a new network tariff structure until those consultations are complete and a decision is published.

Final Thoughts

The review is technical, but the question underneath it is simple: who pays for the grid, and on what basis. Households that generate, store and use their own electricity have done well under the current structure, and using more of what you generate is the surest way to stay that way. Solar, a battery and smart charging are the practical defences against whatever design emerges.
