- Abstract:
- The UK has an ambitious and legally-binding target to reduce its carbon emissions by 80% by 2050 (relative to a 1990 baseline) as part of its commitment to limit its contribution to climate change. Achieving this target will require significant changes in how the UK sources its energy; reducing the use of fossil fuels and increasing the use of a mix of renewable technologies such as wind, solar, tidal and hydropower. The UK currently generates about 1.5% of its electricity from hydroelectric schemes, and although further large-scale development potential is limited, there is scope for exploiting small-scale and micro-hydropower resources (DECC, 2013). However, the potential impacts of such development on the environment and its stakeholders must be evaluated and minimised where possible. This NERC Policy Placement at the Environment Agency will gain a detailed understanding of the different areas of potential concern associated with the development of low head hydropower schemes through consulting with a wide range of stakeholders initiated by a project launch workshop event. External stakeholders may include representatives from rivers user groups (e.g. the Angling Trust, Canal & River Trust, Inland Waterways Association, National Association of Boat Owners, the British Canoe Union and the Ramblers Association), environmental bodies (e.g. Rivers Trusts, Wildlife Trusts, the RSPB, Natural England, English Heritage, Environment Agency, DEFRA), energy organisations (the National Grid, DECC), and the British Hydropower Association. The understanding gained through consultation with stakeholders will be used to inform a life-cycle analysis that compares the environmental impacts of low-head hydropower schemes against all other forms of electricity generation across a comprehensive list of factors (global warming potential, land footprint, water footprint, abiotic depletion potential, acidification potential, eutrophication potential, aquatic ecotoxicity potential), including those factors identified through consultation with stakeholders. Systematic and transparent data and literature searches will be used, as recommended in Dr Bilotta's recent open-access publications co-authored by Defra's Chief Scientific Advisor (Bilotta et al., 2014a;b), to ensure that the findings of the life-cycle analysis are traceable and can be updated in light of improvements in the technologies which can occur rapidly. This comparative life-cycle analysis will enable stakeholders and policy-makers to make a better informed decision about the relative merits and drawbacks of different forms of electricity generation on their respective areas of concern. The project will also identify specific design and siting aspects of low head hydropower schemes that are associated with the most and the least environmental impacts, through collating and statistically-analysing existing monitoring data collected routinely in England and Wales as good practice (Environment Agency, 2014), before and after installation of hydropower facilities. This analysis will be published in a peer-reviewed journal and used, where appropriate, to update the good practice guidelines on hydropower development (Environment Agency, 2014). Ultimately, these guidelines will be used to optimise the design of future hydropower schemes in England and Wales, to minimise their impact and maximise their environmental and social sustainability.
