Tell us about your journey in the energy industry.
My journey in the energy sector began in 2009 with a deep-rooted passion for sustainability and a commitment to making a difference in Angola’s energy landscape. Driven by curiosity, I sought opportunities to learn and exchange experiences by participating in forums, fairs, workshops, conferences, and seminars. These initial experiences were essential for consolidating my foundation in renewable energy and expanding my network of contacts with other enthusiasts—students, professors, and professionals—establishing the pillars of my commitment to sustainable development.
Motivated by a desire to advance clean energy, I pursued a degree in Electromechanical Engineering, culminating in a final project on Electricity Generation from Solid Waste, for which I earned a distinction of 19 values.
In 2011, I seized the opportunity to participate in the Sustainable Development Award, reinforcing my commitment to a sustainable future through this innovative concept of waste-to-energy. By 2014, I gained my first professional experience as a Junior Electromechanical Engineer at SANEL Angola (Angolan Society of Industrial Equipment). In 2016, I attended the first National Training Course for Operation and Maintenance Technicians of Hydroelectric Plants, where I was assigned to Laúca—the largest hydroelectric plant in Angola, with an impressive capacity of 2,070 MW—under the Public Electricity Production Company, Prodel-EP.
My dedication to renewable energy and sustainability led to the founding of ENERE, a startup focused on bringing energy education to Angolan and African communities. ENERE raises awareness about renewable energy and equips young people with the skills to implement sustainable solutions in their communities.
Additionally, I gained experience as an Operations and Production Engineer on various projects. My detailed knowledge of energy regulations and policies in Angola has allowed me to identify and explore business and growth opportunities in the renewable energy sector. I also contributed to several solar energy initiatives in rural Angola, participating in the installation of solar panels and energy storage systems for 40 rural homes during my time at the Alcaal Renovables Group.
Today, as a Renewable Energy Production Engineer at Grupo Omatapalo, I am actively involved in developing solar PV projects totaling approximately 724 MWp. These projects aim to impact lives and transform Angola's energy sector by driving energy diversification and transition.
What do you do in your current role at your company?
I prepare and analyze construction schedules and execute engineering documents released for construction. I manage weekly and monthly schedules, conduct routine inspections, and monitor production activities and physical progress. Additionally, I analyze activities and produce variance reports to track performance.
I oversee cost management and control associated with production, and my responsibilities also include planning and monitoring the entire production chain and its stakeholders. I supervise and coordinate work teams, visit construction sites, and establish contacts with partners and local and regional suppliers.
Lastly, I measure and analyze all yields and production indicators, establish new production processes and procedures, and prepare and monitor engagement plans for projects (Environmental Impact Assessment (EIA) and Environmental and Social Impact Assessment (ESIAS) etc. This involves meeting with stakeholders and directing the Population and Environmental Compensation Plan.
Could you describe your typical day at work?
A typical day for me starts early with a review of the goals for the photovoltaic projects under development. I begin by analyzing performance data from projects, contracts, environmental plans, and other documents, reviewing and refining work procedures, as well as identifying and exploring new activities to enhance the performance of our team.
In the morning, I coordinate meetings with my team to discuss and align on the progress of their activities, including implementing new technologies and solutions to optimize the efficiency of solar systems. I also dedicate time to preparing and reviewing operational reports.
Throughout the day, I visit solar project installation sites to inspect work progress, ensuring strict adherence to safety and sustainability standards. I participate in meetings with directors and stakeholders, presenting results and proposing adjustments to improve efficiency and expand project impact. I also spend time researching technological innovations in the renewable energy sector, always aiming for continuous improvement.
The day concludes with a review of activities and planning the next steps, focusing on energy transition and the development of sustainable solutions for Angola. I am motivated by the opportunity to contribute to the country’s energy matrix, promote access to clean energy, and transform the lives of local communities.
"What I love most about my job is the opportunity to interact with local communities and stakeholders, experiencing first hand their expectations for new clean energy.”

What are some of the challenges you have faced in the industry?
I have encountered several challenges in the renewable energy sector in Angola throughout my career. Some of these challenges include:
Â
- A lack of content and opportunities in the professional market for technicians in renewable energy, which led me to create the startup ENERE. Non-existent professional qualifications compelled me to study abroad for specialization in renewable energies.
- A lack of regulation, funding, policies, and public incentives for researchers and professionals in the sector.

What is the most fun thing you love about your work?
What I love most about my job is the opportunity to interact with local communities and stakeholders, experiencing first hand their expectations for new clean energy. This direct connection allows me to witness the positive impact of renewable energy projects on people's lives, such as access to electricity, local development, and increased environmental awareness. Listening to the needs and hopes of the communities motivates me to find practical and sustainable solutions that address local realities, making the work all the more rewarding.
In addition to engaging with the communities, I also value fieldwork, especially visiting project sites. I enjoy the hands-on aspect of seeing the technology up close and observing how renewable energy systems are implemented and operate in real time. This direct contact with the projects—watching the progress and challenges unfold on the ground—keeps the work dynamic and allows me to apply my knowledge in a concrete way, which is one of the most fulfilling parts of my professional routine.
How do you balance work and life?
I balance work and personal life through effective time management. With responsibilities at Omatapalo, my startup ENERE, and my goal of pursuing a postgraduate course in climate change, I understand that organization and planning are essential. During the week, I focus on professional and academic demands, allocating specific times to each project. For instance, I schedule my course studies for evenings or weekends, ensuring they don’t interfere with my primary commitments.
Despite my various responsibilities, I deeply value time with family and friends. I make a point of setting aside dedicated moments, whether during short daily breaks or planned gatherings on weekends. This balance is crucial for me, allowing me to disconnect and recharge. I believe that achieving a balanced life requires prioritizing and organizing tasks effectively. This approach enables me to focus on career growth and clean energy initiatives without sacrificing quality time with loved ones, ensuring a fulfilling and well-rounded life.
