Drivers and risks for renewable energy developments in mountain regions: a case of a pilot photovoltaic project in the Swiss Alps

Abstract

Background: When renewable policies are in place, the mismatch between policy targets and lack of technology diffusion indicates a gap between codifying a policy and implementing it. In Switzerland, photovoltaic (PV) electricity is seen to play a major role in the future. Stakeholders' opinions in the implementation of photovoltaic projects may block or delay the achievement of renewable policy goals. This paper explores the question: which are the main drivers and risks perceived by stakeholders at different levels of the government in the implementation of a pilot PV project? Methods: We study a decision-making process of a pilot project in the Swiss Alps to figure out which determinants explain the public opposition to such implementation. We study five types of determinants of public acceptance: economy, technology, environment, social aspects, and the policy process. We use Q methodology, which is especially suited to determine the different interests of stakeholders' groups. Results: Our results show four different perspectives: "Mainstream proponents," "Ecologically wary," "Worried about implementation," and "Looking for cantonal and national backing." The results indicate that the photovoltaics' acceptance was highly driven by the potential contribution of the project to the regional economy. However, economy and technology determinants elicited both the highest and the lowest statistical consensus among perspectives (z-score). Our results point out the important role of initiators to maintain trust during the decision-making process. Finally, stakeholders in the photovoltaic project wanted to have fluent access to concrete information about the project and its future plans. Conclusions: Most of the implementation risks observed are determinants of acceptance related to economic aspects and the policy process. Characteristics of the decision-making process, such as trust during the process, affect the perceived outcomes of the project. Aspects of the decision-making process may, therefore, turn into risks for the project's implementation. Results also suggest that techno-economic assessments are key drivers to fostering energy transitions, but they are not sufficient in themselves. Initiators have to consider enhancing communication since the early steps of the policy process, the intelligence and promotion phases to avoid implementation risks.

High-resolution electricity generation model demonstrates suitability of high-altitude floating solar power

“…Public opinion may be against such projects, especially since many of the water bodies in our sample are popular tourist destinations. Previous research on the risks of developing photovoltaic projects in the Swiss alps has found that project acceptance relies heavily on contributions to the local economy, with transparent and regular information flows between stakeholders as a key driver of project approval ( Díaz and Van Vliet, 2018 ) – the study also found that the high complexity of administrative processes related to developing new renewable projects pose a significant implementation risk. Given the existing local relationships and permits held by hydropower facilities, the path of least resistance for implementing high-altitude floating solar is likely to be through associated hydro operators.…”

Stakeholders’ Perceptions of the Possible Energy Sustainability Solutions in the Hotels of the Canary Islands

“…Q is the most adequate technique for understanding subjectivity and leads to more correct policy measures. Different perspectives on photovoltaic energy have also been addressed [37][38][39][40][41]. Previous, solely quantitative research on planning photovoltaic infrastructure led to strictly technical outcomes, where experts' subjective opinions had not been taken into consideration.…”

Coordination challenges in wind energy development: Lessons from cross-case positive planning approaches to avoid multi-level governance ‘free-riding’

“…Second, this study would help identify lessons learned from these strategies efforts and also identify constraints that may need to be addressed for wind energy development. It adds to planning approaches, when there is a missing evolutive linkage between overall energy targets and actual implementation at local level [6][7][8]26,27,59 for solar energy].…”
