Introduction 1.1.1. This Scoping Report has been prepared by Natural Power Consultants Limited (Natural Power) on behalf of Innogy Renewables UK (innogy) in anticipation of an application for a Development of National Significance (DNS) for a wind farm development located approximately 4 km north of Cerrigydrudion within Conwy County Borough Council (CCBC) and Denbighshire County Council (DCC). This scoping request is made in relation to a Development of National Significance for the purposes of section 62D of the 1990 Act. 1.1.2. Under the statutory procedures set out in The Town and Country Planning (Environmental Impact Assessment) (Wales) Regulations 2017 (EIA Regulations) it is proposed that any such application is accompanied by an Environmental Statement (ES). 1.1.3. The purpose of this Scoping Report is to provide sufficient information for consultees to agree the scope of the ES. Information has been provided on what the applicant intends to assess within the ES. When the applicant is proposing to ‘scope out’ particular elements sufficient information and justification has been provided in this report. The intention is to ensure the focus in the ES is on any receptors impacted by the proposed development that may experience significant effects. 1.1.4. Consultees will note that the Scoping Report contains a number of questions, which it would be useful to receive a response on. Not all questions will be relevant to all consultees; therefore we request that consultees provide feedback only on those questions appropriate to them. The questions should not be considered an exhaustive list, and consequently, consultees are invited to provide further responses on any issue they consider relevant to the proposed development. If consultees elect not to respond, innogy will assume that consultees are satisfied with the approach adopted/proposed. The Applicant 1.1.5. The applicant, Innogy Renewables UK Limited (innogy), develops, builds and operates projects to generate power and extract energy from renewable sources. It is part of Innogy SE; an established European energy company which was formed from the restructuring of the RWE Group and started operations on 1 April 2016. innogy firmly believes in making our planet a better place. innogy has eight offices across the UK and operates more than 1 gigawatt of renewable energy capacity. In the UK, innogy currently operates 18 onshore wind farms, 3 offshore wind farms and 24 hydro sites.
