One Solar Farm Could Power 51% of County Waterford – Locals Have Questions

Amarenco’s proposed solar installation near Cappoquin covers 100 hectares across three linked sites and, if built, would generate enough electricity to supply 28,000 homes. That is 51% of all households in County Waterford from a single project on agricultural land between Modeligo and Cappoquin. The number is real. It is based on standard utility-scale solar output calculations at current panel efficiency and average Irish household consumption.

The public consultation meeting at Modeligo Community Centre last month drew residents who understand that number and want to know what it costs in land use terms. That conversation is not resolved yet.

The Project Structure and Why Three Sites Matter

The three land parcels operate as a single generation unit but are separately titled. That structure creates a planning architecture where each parcel needs individual environmental assessment while the aggregate capacity and grid connection are evaluated at the combined level. It is a format Amarenco has used on other Irish projects. It makes the full picture harder to see in any single planning document, which is one reason community groups find it difficult to engage with the proposal comprehensively.

The 100 hectares is photovoltaic panels on land currently in mixed agricultural use. The developer has proposed agrivoltaic operation – sheep grazing between panel rows throughout the operational life of the project. This is the most common animal husbandry format on Irish solar sites and it does preserve some productive land use. Whether it preserves the same agricultural productivity as the unmodified land is a different question that the environmental impact documentation needs to answer specifically.

The Two Objections That Came Up at Modeligo

The first is glare. Solar panels reflect light based on angle, surface coating, and time of day. Modern anti-reflective coatings substantially reduce specular reflection relative to older panel technology. “Substantially” still leaves a range, and neighbours to a 100-hectare installation experience whatever sits in that range at close range every clear morning and evening for the project’s entire operational life. Amarenco has not published a formal glare assessment for the Cappoquin sites. That document should exist before the planning application advances, not after.

The second objection is the agricultural land question, which the agrivoltaic response only partially addresses. The community at Modeligo is asking about the long-term productivity of the land. Sheep can graze between panels. The question is whether the land can return to full cultivation if needed in twenty years. That question has a technical answer that requires soil assessment and solar footprint analysis. It was not answered at the community meeting.

County Waterford’s 2030 Renewable Target Makes This Project Inevitable in Some Form

The county’s statutory development plan commits Waterford to contributing to national renewable targets that require new generation capacity before 2030. Solar is the fastest deployment technology available: utility-scale projects run 24 to 36 months from planning application to grid connection. Wind takes longer. The arithmetic of the county’s renewable obligations makes a project of this scale necessary at some point before the decade ends.

The question is not whether a large solar installation belongs in County Waterford. It is whether this specific site, in this specific configuration, with these specific mitigation commitments is the right implementation. The environmental impact documentation that accompanies the full planning application will determine how precisely that question gets answered.

What Comes Next on the Planning Timeline

The project is currently under consultation. No formal planning application has been submitted as of April 2026. Once submitted, projects of this scale typically take 12 to 18 months to a first-instance planning decision, with appeals extending that timeline.

The next document the community should expect and ask for is the formal environmental impact assessment, which must include the glare study and the agricultural land impact analysis that the consultation meeting identified as the two specific outstanding questions.

51% of county households is a real number. The land use question deserves real answers before the planning clock starts.
