When did you join Natural Power? 

I joined Natural Power in November 2022. I moved from OFGEM to Natural Power after completing my master’s degree in mechanical engineering. 

What does your role entail? 

The scale of our projects ranges from decarbonising individual community buildings all the way to investigating the feasibility of a district heat network. As a renewable heat engineer, I play a pivotal role in supporting the transition of buildings and communities to sustainable futures. My responsibilities vary by project but may include site visits and building audits where I will check on a building’s condition, its heating systems and look for areas for improvement. Then I may look at the renewable heat options with clients or building managers considering factors such as building size, usage patterns, and local climate. From there I might conduct in-depth calculations to figure out the best renewable heat system for each client, considering factors like energy demand, system efficiency, and cost-effectiveness. Other areas I might work on are system design where I would propose the best equipment, layout, and installation methods; supervising installation so that it follows the design specifications and industry standards; and troubleshooting where I can provide technical support to address any issues that arise during installation and operations. As renewable heat is rapidly evolving, I am also passionate about exploring new solutions by researching and evaluating emerging technologies to identify potential opportunities for innovation. 

What are the most rewarding and challenging parts of your role? 

As a renewable heat engineer, I find the role incredibly fulfilling due to the positive impact it has on both individuals and communities. It is rewarding because I can contribute directly to the reduction of carbon emissions and combat climate change which is essential for building a more sustainable future for generations to come. I can also help enhance local communities by increasing the energy efficiency and sustainability of community centres, village halls, and leisure centres which, not only reduces operating costs, but also creates more comfortable and welcoming spaces for the community to enjoy. By transitioning to renewable heat sources, these communities can become less reliant on fossil fuels and reduce their vulnerability to energy price fluctuations which leads to greater energy independence. I take great satisfaction in knowing that my work is directly contributing to a more sustainable and equitable future is immensely rewarding. It is a privilege to be able to help communities achieve their decarbonisation goals and improve the quality of life for their residents. 

While the role of a renewable heat engineer is highly rewarding, it can also present several challenges such as the technical complexity of the technology and intricacy of the system design required. I also have to stay up to date with the standards the renewable energy sector is subject to so that my projects comply with all legal requirements. Cost is another big factor so I often have to balance the desire for optimal solutions with budgetary constraints and uncertainty in forecasting energy markets which can require careful planning and negotiation. Then there’s the unique challenges each site presents from the characteristics of the building to the local climate, and existing infrastructure. You must be adaptable to tailor your solutions to these specific conditions. Finally, there’s the need for collaboration with architects, building contractors, and other professionals where effective communication and coordination can be challenging, especially when working with individuals who have different priorities! 

What is the most interesting inspection project you have undertaken and why? 

One of the most intriguing projects I've encountered involved a news printer which I visited during a district heat network survey. While not a typical source of waste heat, I discovered that the printing presses generated a significant amount of excess energy. This presented an opportunity to both reduce the printer's energy costs and contribute to the sustainability of the district heat network. 

I found this project particularly interesting because it highlighted the potential for unconventional sources of waste heat. It serves as a reminder that even in unexpected places, there can be valuable energy that can be captured and utilised. 

What do you like about working at Natural Power? 

While living in rural Scotland can present challenges for those commuting to city-based offices, I've found that remote working offers a significant advantage. Natural Power's commitment to a flexible work environment allows me to effectively balance my professional and personal responsibilities. Moreover, my rural location provides a unique benefit: being ideally situated to serve our clients on the Scottish Islands. This proximity allows for more efficient project oversight and a deeper connection to the communities we support.

Provide a hidden talent or quirky fact about yourself!? 

I volunteer as a Cubs Scout Leader for the 19th Argyll Lochgilphead Scouts. Most weekends you will find me out and about being eaten by midges!
