changing demand patterns, but we’re also seeing a resurgence in interest in pumped hydro as a storage solution. This is bringing opportunities for my home state of Tasmania, with the ‘Battery of the Nation’ project, which Entura is supporting extensively. Pumped hydro is also creating new, exciting opportunities for the private sector. We’ve been supporting Genex Power’s 25MW Kidston Pumped Hydro project, which is the first pumped hydro to be constructed in Australia for 40 years. It’s a leading example of using pumped hydro to complement wind and solar developments, while making productive use of former mining pits. These sorts of projects will call for innovation, particularly in the complex area of the optimum technical integration of high-penetration renewables with storage (such as we have developed for hybrid off-grid projects including the Agnew Hybrid Renewable Project in remote Western Australia), and the commercial and technical considerations for successful grid integration.
In Australia, we’re already seeing the lived reality of a changing climate, with increased frequency and severity of extreme climate conditions including drought, floods, fire and storms. We urgently need action towards climate resilience and climate-resilient infrastructure. Hydropower has a vital role to play in this – not least in flood mitigation. But when thinking about resilient infrastructure, the hydropower industry also needs to carefully plan ahead given the scale of the oncoming asset management challenge. The amount of hydropower infrastructure in Australia and the Indo-Pacific that is reaching later stages of its design life will be keeping engineers very busy in these regions over many years to come. Another challenge and opportunity in the sector is the rapid pace of technological change. The speed of digital disruption and advances in emerging technologies is dizzying, so we need to stay abreast of change and find the best application of new technologies to reach our goals and deliver what our clients need from us. There’s a great opportunity here for the engineering sector – but it will need skill development, knowledge sharing and careful workforce planning.
Key lessons I’m often asked about whether my gender was any impediment in what has traditionally been a male- dominated industry. For me, it hasn’t been an issue, but I recognise that there is still a lot of work to be done to make the profession more inclusive and diverse. I had some great mentors who encouraged me to take opportunities that I may not otherwise have had the self-belief or confidence to grasp – so I believe in paying that back by championing the supportive factors necessary to attract and retain women in engineering.
Memorable projects Like many engineers, I’ve worked on a huge variety of tasks and projects throughout the Indo-Pacific region. There are many memorable projects, but a particularly exciting opportunity right now is, literally, very close to home. The ‘Battery of the Nation’ initiative in my home state of Tasmania is a once-in-a-generation (possibly once-in-many-
generations) transformative opportunity to explore future development of wind and pumped hydro, repurposing and optimisation of existing hydro, and more transmission and interconnection. It stands to be a game-changer for the energy transition in Australia as thermal coal progressively exits the market. I couldn’t be prouder to be on the steering committee, and to be part of bringing fresh thinking to solve the energy trilemma and pave the way to an affordable, reliable, sustainable energy future. ●

I am a civil engineer, graduated in both project design and construction, with an MBA in capital markets and applied statistics, and professional experience in project design and construction, financial markets and corporate management. I have been working in the Brazilian electricity
sector since 1994 and for ENGIE Brasil since 1996, where I am currently responsible for communications and sustainability at an executive level.
ENGIE is one of the largest energy and services companies in the world. In Brazil it controls over 12,000MW of installed capacity in 69 power plants of all sources (mainly big HPPs). It is the country’s largest private electricity producer, with around 6% of total installed capacity. ENGIE has built a reputation of allying professionalism, profitability, and social and environmental responsibility in implementing and operating big hydro power plants across the country.
I have actively participated in the development and implementation of numerous hydropower plants, including Serra da Mesa (1275MW), Itá (1450MW), Machadinho (1140MW), Cana Brava (450MW), São Salvador (243MW), Estreito (1.087MW) and Jirau (3750MW). I have also participated in the development of the Tapajós HPP (6133MW).
I have been an IHA Board member since October 2009 and subsequently elected Vice-

He says it is an honour to contribute to the work of the IHA and help pave the way in advancing sustainable hydropower at global level. He values being able to bring the Brazilian perspective to the table and says his experience of working on Itá hydropower project, in the south of the country, was one of his most memorable
