Solar Park Impacts on Ecosystem Services: a Framework for Best-Practice (SPIES)

Ensuring there is sufficient energy is a global challenge, caused by increasing demand and the need to move to low carbon energy to avoid dangerous climate change. Photovoltaics, including those mounted on buildings and the ground, are predicted to provide a key component of energy in the future, with the recent US Clean Power Plan and policies in China and Japan placing particular emphasis on solar power. Further, solar energy is increasingly cost competitive, with large scale solar park costs now similar to that of conventional energy sources. Within the UK, 47 % of solar photovoltaics are ground-mounted as solar parks. There has been a shift towards ground-mounted solar parks in countries within 35 degrees of the equator and a shift toward large-scale ground-mounted systems in Europe is anticipated. Solar parks take up a relatively large area of land for the energy they produce compared with conventional sources of energy. Yet, despite the expanding land area occupied by solar parks little is known of the impacts of their construction, physical presence and management on the landscape, or how we can use the opportunities provided by this land use transition to bring additional benefits, such as enhanced green infrastructure and ecological connectivity. Alongside switching to low carbon energy sources, in the light of growing populations and heightened pressures on resources, it is becoming increasingly recognised that we need to protect our environment, since it provides many goods (e.g. crops) and services (e.g. carbon storage) that contribute to the wellbeing and economic prosperity of society. The increasing land cover of solar parks presents an excellent opportunity to maximise the provisioning of such goods and services, with management options relatively low cost compared with those related to solar park construction. Therefore, this project will develop a decision-support tool to assess the impacts of solar parks, including their construction, physical presence and management, on the goods and services the landscape provides. There are five key components:1. Synthesis of existing solar park guidelines;2. Production of a compendium of the beneficial and detrimental effects of solar parks on goods and services supplied by the landscape;3. Quantification of the change in goods and services over the operational life-time of solar parks;4. Development of a decision-support tool that promotes the optimal deployment and management of solar parks;5. Dissemination of the outcomes of the project to the broader solar development community.There are 11 project partners, covering all solar park stakeholders: Christine Coonick, National Solar Centre; Ed Jessamine, Novus Solar; Nick White, Natural England; Jonathan Scurlock, National Farmers Union; Jon Abbatt, ADAS; Richard Winspear, RSPB; Melanie Dodd, Wiltshire Council; Adam Twine, Colleymore Farm; James Ryle, Good Energy; and Phillip Duncan, Corylus. The key output from the project is the SPIES (Solar Park Impacts on Ecosystem Services) decision-support tool, which will provide a standardised means of identifying the best way to install and manage solar parks. Thus the tool will be useful for developers, consultees and regulatory agencies and may reduce prolonged and expensive planning applications, which will be beneficial to all parties. The National Solar Centre will help us drive the tool into policy which would lead to a noteworthy sustained contribution to sustainable energy generation and the supply of goods and services from the landscape. Further, given the global proliferation of solar parks and the growing global awareness of the importance of our natural environment, the proposed tool could help to stimulate innovation in business and investment opportunities, and build the UK's reputation as a global leader in solar park deployment.Keywords: solar parks, low carbon energy, ecosystem services, green infrastructure
