This summary concerns the results for Torfaen County Borough Council (TBC). The purpose of the study is to provide an evidence base for the potential development of renewable and low carbon energy within the two local authorities, to examine the low carbon potential for strategic development sites and explore strategic leadership opportunities. The study methodology has followed the Welsh Government Planning for Renewable and Low Carbon Energy – A Toolkit for Planners (July 2010). Renewable electricity potential This study has identified a total renewable generation potential in Torfaen of 283GWh/yr equivalent to 67% of the projected electricity consumption of the authority area in 2021 of 420GWh/yr. The largest potential resource is wind power, followed by solar photovoltaics (PV). Only 3% of the total renewable energy resource is currently being exploited, excluding waste resources, the majority of which are currently exported outside of the county for treatment and disposal. Renewable heat potential The potential for renewable heat is calculated to be of 116 GWh/yr, equivalent to 11% of the projected heat demand for the authority area in 2021. The largest potential heat generation resource is energy from waste, with a potential 77 GWh/yr, followed by energy crops and wood fuel. Renewable energy targets Renewable energy targets for the county are proposed based on high and low scenarios of resource exploitation. The high scenario is roughly equivalent to UK targets for 2020, albeit with over achievement of the 30% by 2020 renewable electricity target (39%) and underachievement of the 12% heat target (8%, or 3% excluding waste). The energy opportunity map shown on the next page identifies, spatially, some of the key renewable energy resources available within the authority and areas of least constraint. An electronic version of the map with a higher resolution base layer is to be made available to accompany this report. 6 Renewable and Low Carbon Energy Assessment 7 Renewable and Low Carbon Energy Assessment We identify the following as potential opportunities within
