Our People Spotlight series gives you an inside look at our technical experts around the world. This week, we are highlighting our Environmental Impact Assessment Lead for Ireland and providing you insight into his inspiration and work. 

Peter O’Connor has over two decades of experience spanning the energy, power, minerals and waste sectors, having worked on a diverse range of projects across Europe throughout his career. He combines technical expertise with a passion for mentoring early-career team members and delivering impactful projects that contribute to Ireland’s energy transition and sustainability goals.


Tell us about what inspired you to join the industry.

I started off with passion and fascination with maps and geography. I wasn’t sure what I wanted to do, but then I went to an open evening for a surveying course in Dublin. I always loved the idea of working outdoors rather than being stuck behind a desk. The course opened doors to travel across Europe, working on surveying different projects through Erasmus and similar summer schemes between third level institutes.

I started my career in a company that specialised in mineral surveying. From there, I began working on various projects, which gradually led me to focus on energy and power. I’ve certainly had my share of experiences in the field — many of which include challenging site and weather conditions.

Initially, I was directly involved with mineral exploration, management and extraction projects. This progressed to managing mineral waste, which eventually transitioned into commercial and industrial waste projects and nudged my career into the world of the circular economy. I’ve been directly involved in projects where we reduce waste, manage resources and harness energy, and now work on a range of thermal and renewable energy generation sector projects. It’s interesting to witness how interconnected these elements are in our industry, a true circular economy and the challenges that the modern world brings with it. Joining AECOM was a perfect fit and the role allowed me to combine my expertise in energy and power sectors, with my ability to mentor early-career professionals while allowing me to become a trusted advisor for clients.

What is your favorite AECOM project that you’ve worked on and why?

One of the most rewarding projects I’ve worked on is the Kilroot Power Station project in Northern Ireland. The project kicked off shortly before the first coronavirus lockdown in 2020 and involved transitioning a coal-fired power station to gas, which required pre-application work for a gas pipeline connection and integrating advanced technology. It wasn’t without its challenges — lockdowns, social distance site visits and a challenging programme managing a large multi-disciplinary environmental team was part of the job — but seeing the project secure consent, constructed and go live was incredibly fulfilling and rewarding. The early-career team members were excited about the projects as well, because they knew that the client was invested, and they could see the full project lifecycle — design to consenting to construction through to implementation — be delivered in a relatively short period of time. Our team’s environmental expertise and robust Environmental Statement and support to the planning process ensured the project itself contributed to cleaner energy solutions in the region and is a great example of how our work can make a real difference.

Tell us a story of how your work positively impacted the community.

Many of the projects I work on are large‑scale in nature, and as a result, their impact is both far‑reaching and undeniable. Our clients are deeply committed to strengthening energy security during a critical transitional period on the journey toward net zero. Being part of this work — especially at a time when the industry is navigating such complex challenges and ambitious sustainability goals — feels genuinely meaningful.

Knowing that our contributions help keep essential services running, support long‑term resilience, and ultimately play a role in keeping the lights on is incredibly rewarding. There is also a strong sense of purpose in recognising how this work supports wider economic growth, both by enabling the energy sector to operate efficiently and by helping create the conditions for future investment and innovation. The scale and significance of these projects make the work both motivating and fulfilling.

Share a piece of career advice.

My advice to anyone starting their career is to embrace opportunities and stay adaptable. It’s okay not to know exactly what you want to do early on so expose yourself to as many different experiences as possible and don’t pigeonhole yourself too soon. Never stop challenging yourself, always be open to adapt your skill set and keep your professional development forefront of your personal and professional goals. With that in mind, I encourage early-career team members to work towards relevant chartership and professional memberships early in their career. Listen to your peers, absorb as much knowledge as you can, and focus on building strong relationships.

I often encourage early‑career team members to talk to everyone. When you’re on a site visit, take the time to chat with — and really listen to — the people on site or in the office. These conversations help you understand exactly what stakeholders and clients need.

Our Impact Assessment team collaborates with a wide variety of clients and technical teams, and sometimes we’re the face of those teams on projects. Remember: the early‑career professionals of today are the leaders of tomorrow, and the connections you build now will be invaluable throughout your career.
