Brixworth Windfarm Environmental Statement August 2008 Prepared by Arcus Renewable Energy Consulting Ltd on behalf of Bolsterstone Plc Brixworth Windfarm Environmental Statement Preface PREFACE This Environmental Statement accompanies the application by Bolsterstone Innovative Energy (Brixworth) Ltd, to Daventry District Council, to construct and operate a windfarm near Brixworth, north of Northampton in Northamptonshire. This Environmental Statement has been prepared by Arcus Renewable Energy Consulting Ltd on behalf of Bolsterstone and consists of: 1. Non-Technical Summary of the Environmental Statement 2. Environmental Statement – main volume text, figures and visualisations 3. Technical Appendices - supplementing the findings of the Environmental Statement Copies of the Environmental Statement can be consulted at the following locations, by arrangement: Daventry District Council, Town Hall, Daventry Daventry Library, North Street, Daventry Northampton Library, Abington Street, Northampton The Non Technical Summary can be obtained free of charge and the full Environmental Statement can be purchased for £150 per copy. Alternatively the ES is available for £20 on CD- ROM. Copies of the Environmental Statement and the Non-Technical Summary can be obtained from: Arcus Renewable Energy Consulting Ltd Suite 2F Swinegate Court East 3 Swinegate York YO1 8AJ Bolsterstone Plc i August 2008 Brixworth Windfarm Environmental Statement Non-Technical Summary greenhouse gas emissions in 2006 had fallen 15% below 1990 levels while carbon dioxide NON-TECHNICAL SUMMARY emissions were 5% below 1990 levels in 2006, (Meeting the Energy Challenge A White Paper on Energy, May 2007, DTI). Another main objective is to move towards obtaining 10% of the UK’s electricity supply from INTRODUCTION renewable sources by 2010, with an aspiration for 20% renewable generation by 2020. In 2006 electricity supplied from renewable sources stood at around 4% of the UK’s total. This Non-Technical Summary forms part of the Environmental Statement to accompany an application by Bolsterstone Innovative Energy (Brixworth) Ltd (“the developer”) for a The East Midlands RSS proposes a minimum regional energy target of 2495 GWh by 2010 and a 6 turbine windfarm of approximately 12MW near Brixworth, north of Northampton in suggested requirement by 2020 of nearly 5000 GWh. The RSS notes that at present renewable Northamptonshire. The location of the site is shown in Figure NTS 1.1. energy sources make only a minor contribution to the regions capacity (1.6%) and the proposed targets represent 10.6% of the overall electricity consumption at 2010. Bolsterstone was originally formed in 1988, its first project being to construct an industrial estate on the M18 near Rotherham. Since that date a wide range of property Policy 41 states that Development Plans and future Local Development Frameworks should related investments have been made by the directors through various corporate bodies include policies to promote and encourage the delivery of the indicative County Area 2010 which they run. There are over twenty actively trading or investment companies/bodies targets for renewable energy, as set out in Appendix 6 within the East Midlands RSS. The corporate, owning a wide range of assets including substantial office blocks let to the overall target for renewable energy in the East Midlands by 2010 is 671.6MW with onshore wind government, retail parades and several investments leased to substantial companies. contributing 122MW of this. In Northamptonshire the County Area 2010 target for renewables is Bolsterstone acts as the project management company to the other subsidiary and 55.5MW, of which 12MW is proposed from onshore wind energy. However the RSS emphasises associated companies. that these are minimum targets and consideration should be given to any further targets that may emerge. Bolsterstone has ambitions to become a major provider of ‘green energy’ in the UK. In conjunction with funders, an initial tranche of £50,000,000 has been earmarked for The installed capacity of Brixworth Windfarm will be approximately 12MW, which could provide investment in renewables, of which the majority will be invested in onshore wind power. enough energy for approximately 6260 homes and has the potential to contribute CO2 emission reductions of approximately 16,975 tonnes1 during each year of its 25 year operational life. Bolsterstone intends to fulfil its ambition to help provide a secure energy supply for the nation, reduce climate change and provide a better environment for future generations. ENVIRONMENTAL IMPACT ASSESSMENT The current group thinking revolves around ‘future proofing’ it’s investments by better design of new build projects and incorporating energy efficient technologies and vastly The Environmental Statement (ES) has been prepared to accompany the planning application, in improved insulation values during refurbishment of its estate. accordance with the Town and Country Planning (Environmental Impact Assessment) (England and Wales) Regulations 1999 (“The EIA Regulations”).

It is working after prior assessment of the likely significant environmental effects has been carried out and closely with BRE to ensure this development is a model of what can be achieved with suitable mitigation or management measures identified. available technology. CONSULTATION AND SCOPING Energy underpins virtually every aspect of the economy. However, the use of fossil fuels such as gas and coal, which currently provide the bulk of our energy, releases The aim of the Scoping process is to identify key environmental issues at an early stage, to greenhouse gases (such as carbon dioxide) into the atmosphere which directly affects determine which elements of the proposal are likely to cause significant environmental effects our climate. To help lessen the effects of climate change, greenhouse gas emissions and to establish the work required for the preparation of the ES. must be reduced. One way of helping to achieve this is by generating energy from sources that emit low or even zero levels of greenhouse gases, such as renewable A scoping opinion for Brixworth Windfarm was requested from Daventry District Council by sources.

The turbines would generate electricity in wind speeds between 4 and 25m/s. At wind speeds greater than 25m/s (56mph) the turbines would shut down for self-protection. Such high wind SITE SELECTION AND LAYOUT DESIGN conditions occur for a maximum of approximately 1% of the year. This windfarm would be generating electricity for approximately 80-85% of the year. Bolsterstone have been meticulous in their search for potential sites for wind energy projects in England. The windfarm will be connected to the national grid via a substation building in the eastern section of the site. The grid connection is the responsibility of CE Electric UK (Central England Using advanced wind speed and duration evaluation software and techniques, Electric) and the details of which would be agreed with Daventry District Council. Bolsterstone have investigated a number of potential sites to develop shortlists of sites which satisfied initial technical viability criteria.
