New NPWS guidance published: Key takeaways for renewable energy developers in Ireland

The NPWS has published new guidance [1] explaining how developers should engage with them under the RED III planning regime. There has also been recent European Court of Justice (ECJ) judgement [2] which will play a vital part in early engagement.

What are the key takeaways of the new NPWS guidance?

Early engagement

The main message is that early and ongoing engagement with NPWS is now more important than ever. With mandatory scoping, completeness checks, and shorter decision-making timelines, developers may have limited opportunities to address ecological issues once an application has been submitted.

Developers are encouraged to contact NPWS at an early stage, before project layouts and infrastructure locations are fixed. Initial discussions should focus on the proposed development area, potential ecological sensitivities, and the scope of baseline surveys. NPWS may provide advice on survey methodologies, key biodiversity receptors, and potential impacts that need to be considered.

Continuous engagement

The guidance envisages a series of engagements rather than a single meeting. As survey work progresses, applicants should return to NPWS to discuss survey findings, likely impacts, proposed mitigation measures and, where necessary, potential compensation measures. The guidance notes that project design may need to evolve in response to ecological constraints identified during this process.

Thorough biodiversity exploration

A key feature of RED III is the introduction of mandatory EIA scoping. While NPWS contributes to the process, it is the competent authority that issues the Scoping Opinion. The guidance emphasises that biodiversity issues should be fully explored before the scoping stage because the scope of information required for the EIAR cannot generally be expanded once the Scoping Opinion has been issued.

NPWS does not have a formal role in the subsequent completeness check and expects most substantive biodiversity issues to have been resolved during pre-application consultation. During the statutory consultation stage, NPWS is likely to focus primarily on matters that remain outstanding.

The guidance also highlights the importance of discussing potential Article 6(4) derogation issues at an early stage where significant effects on a European site cannot be ruled out. Although any decision to pursue a derogation rests with the competent authority following Appropriate Assessment, early consideration of alternatives and compensatory measures may help avoid delays later in the process.

In summary, the guidance reinforces a ’front-loading’ approach to ecology and Appropriate Assessment, with strong emphasis on early survey design, iterative engagement with NPWS, and resolving biodiversity issues before an application enters the formal planning process.

Early consideration of site-specific conservation objectives is key

Further to the new NPWS guidance, recent European Court of Justice (ECJ) judgement concluded that a valid Appropriate Assessment cannot be carried out unless site-species conservation objectives for the Natura 2000 site concerned have already been established [2]. The cases arose from challenges to planning permissions granted for wind energy developments in Co. Waterford and Co. Cork that were assessed against the Blackwater Callows special protection areas (SPA). At the time the decisions were made, Ireland had not yet adopted specific conservation objectives for that SPA. The judgment confirms that conservation objectives must be site-specific, precise, and established in advance. They are a fundamental prerequisite for assessing whether a project could adversely affect the integrity of a protected site. This should be an early consideration for consultation with NPWS.
