GLENKERIE WINDFARM NON TECHNICAL SUMMARY INTRODUCTION Scottish Natural Heritage (SNH) and other statutory and non-statutory agencies. The ES Novera Energy plc (Novera) proposes to contains the environmental information develop a small wind farm at Kingledores Farm required for the determination of the Glenkerie in the Scottish Borders.

Novera has a portfolio of landfill gas, water and Figure 1 - Site Location waste, hydro and wind assets, generating renewable power at 58 sites across the UK with a total installed capacity of 122 MW. Novera is one of the largest generators of renewable energy in the UK and with over 140 members of staff is one of the largest employers in the UK Renewables sector WIND – CLEAN ENERGY FOR A SUSTAINABLE FUTURE It is now widely accepted that global warming and climate change are a reality and have the potential to cause major adverse effects on sea levels, water supply and agriculture in the coming decades. Within the UK, we now clearly understand that climate change will have some or all of the following impacts: • Extremes in weather, with dry areas The scope of the ES was agreed with SBC, becoming drier and wet areas wetter; • Increased bouts of flooding; NOVERA ENERGY PLC NTS Page 1 of 12 GLENKERIE WINDFARM NON TECHNICAL SUMMARY • Increased erosion to coastal land, leading energy.

In achieving this target, it is expected the UK will save around 2.5 million tonnes of carbon emissions annually. THE GLENKERIE WIND FARM The Glenkerie site area is approximately 360ha and is made up of heath, grassland and small conifer and broadleaved plantations on the lower areas. The components of the Wind Farm that will be on site for 25 years are: Table 1 - Glenkerie Wind Farm Components 11 wind turbines 8km of new access tracks from A701 The final design for the turbine foundations 1.3km of upgraded tracks and the quantities of concrete needed will be determined by the ground and rock conditions Crane hard standing next to each turbine at each location. However, it is anticipated that up to 300m3 of concrete per turbine base Control building will be required. Concrete will be imported to Underground cables to each turbine the site ready mixed.
