Residents near Aviva’s Pitheavlis office in Perth are experiencing disruptions caused by the recently installed wind turbine’s shadow flicker. Perth and Kinross Council confirmed a neighbour’s complaint about the flickering shadows cast by the turbine’s rotating blades was “justified,” leading Aviva to implement shutdown procedures. The 77-meter structure, which became operational late last year, was intended to work in conjunction with existing solar panels to fully power the Aviva office. Addressing Shadow Flicker Issues
Shadow flicker, a phenomenon occurring when sunlight is interrupted by the spinning turbine blades, can create an irritating visual effect for those living nearby. The impact is influenced by several environmental elements, such as the intensity and angle of the sun, wind patterns, and the presence of clouds. Aviva’s comprehensive shadow flicker management plan, crafted by 350 Renewables, outlines conditions under which the turbine should cease operation to mitigate these disturbances. These conditions are most likely to occur in Perth between late September and mid-March, when specific sunlight and shadow conditions coincide.
Following a complaint lodged on February 6th, the council initiated an enforcement investigation. Planning officer Sean Panton’s report stated a planning condition had been breached, leading Aviva to voluntarily implement further shutdown protocols as detailed in their shadow flicker management plan. The council now considers the issue resolved. While these shutdowns address the resident’s concerns, they potentially impact the turbine’s overall energy generation capacity and Aviva’s goal of achieving 100% renewable energy for its Perth facility. Community Impact and Future Considerations
The turbine’s presence has generated considerable discussion within the community since its approval in 2022. Some residents voiced surprise at the scale of the structure during installation in October 2024. Despite the turbine’s initial promise of sustainable energy and its celebratory naming as “Aurora” by Viewlands Primary School students, challenges remain. This isn’t the first hurdle faced by the project. Late last year, the council also raised safety concerns about Aviva’s initial proposal to prominently display their logo on the turbine.
The current situation highlights the complexities of integrating renewable energy infrastructure within residential areas. Balancing the benefits of sustainable power generation with the potential impact on residents necessitates careful planning and ongoing communication between developers, local authorities, and the community. While the specific frequency of shutdowns and the number of affected residents remain undisclosed, the incident emphasizes the importance of addressing shadow flicker concerns to ensure harmonious coexistence between renewable energy projects and the surrounding community. As Perth continues to explore and adopt sustainable energy solutions, the lessons learned from the Aviva wind turbine will be crucial in shaping future initiatives and ensuring minimal disruption to residents.
