Entura welcomes visit from India’s High Commissioner to Australia
Entura recently welcomed a visit from India’s High Commissioner to Australia, Mr Manpreet Vohra, and Consulate General of India, Melbourne, Dr Sushil Kumar.
The pair travelled to Hobart, Tasmania, last week, where they met with Entura’s Managing Director, Ms Tammy Chu, Director of Strategy, Sales and Commercial, Dr Amanda Ashworth, and Senior Consultant, Mr Ajit Garg.
“It was a pleasure to meet Mr Vohra and Dr Kumar during their visit to Tasmania,” said Tammy. “It was a great opportunity to further strengthen our close relationship with India, and discuss how we can support one another in achieving our mutual clean energy goals.”
“I have been privileged to be involved in furthering the India–Australia relationship through several events this year, as a member of the Australian Senior Business Delegation to India and a subsequent Roundtable with business leaders in Sydney. I am also now on the Australia–India CEO Forum’s Energy, Resources, Net Zero and Critical Minerals Joint Working Group.”
“These opportunities have been realised through Entura’s close work with India,” said Tammy. “We have forged relationships with government officials across the country and within Australia over many years. Entura is an excellent example of how India and Australia can support each other towards our clean energy goals and the path towards net zero.”
Entura has had a physical presence in India for 17 years, through the Entura office in New Delhi. The highly skilled India team consults to clients throughout South and South-East Asia, as well as contributing to Australian projects.
Entura has also delivered successful exchange programs, training workshops and capacity-building initiatives in India through the Entura clean energy and water institute (ECEWI). This includes dam safety training for India’s Central Water Commission as part of its Dam Rehabilitation and Improvement Project (DRIP), and the South Asia Regional Infrastructure Connectivity Framework – an Australian Department of Foreign Affairs and Trade initiative.
“Developing a skilled workforce is such an important part of the clean energy journey, and we’ve been able to provide knowledge sharing and capability building to our partners in India to achieve this,” said Amanda.
“Lifting the capability of the industry’s current and future professionals is a critical part of ensuring ongoing sustainability of the power and water sectors, and there’s much we can share with – and learn from – our international counterparts.”
Entura experts reflect on the Symphony of the Renewables World Wind Energy Conference 2023
Experts and thought leaders from Australia and overseas came together this month for the 21st World Wind Energy Conference (WWEC), held in Hobart, Tasmania.
This year’s theme was ‘Symphony of the Renewables’, highlighting the advantages of integrating wind power with other renewable energy sources and storage solutions. It was the first WWEC held in Australia since 2005.
As an avid player in the wind power sector, Entura was represented at the conference by our Director, Strategy, Sales and Commercial, Dr Amanda Ashworth, and Senior Principal, Renewables and Energy Storage, Dr Andrew Wright. Our Principal Renewable Energy Engineer, Ray Massie, was also in attendance, giving a presentation on ‘The rapid growth in off-grid hybrid systems in Australia and Pacific’.
“When Hydro Tasmania started deploying renewables into remote off-grid power systems, there were few if any prior examples to turn to, so we were pioneers,” said Ray.
“When we started this journey there were many questions around system reliability and availability, power quality, protection system and operational complexity, to name a few. We pushed through the technical challenges to create world-leading examples of how zero-diesel operations can be achieved in remote locations.
“It’s exciting to see the progress that has been achieved since those first forays, and to see off-grid hybrid systems at large scale now being deployed on a fully commercial basis.”
Entura’s parent company, Hydro Tasmania, also had a presence at the event, with CEO Ian Brooksbank and Executive General Manager Strategy, Erin van Maanen, both among the 25 keynote speakers.
“Sitting in that room made me proud to be part of Entura, and the wider Hydro Tasmania,” Amanda reflected. “Our people are incredibly talented and have made a significant contribution to renewable energy projects in Australia and internationally. It’s a testament to the expertise we’ve developed and shared between both businesses.”
“It also made me proud to be a Tasmanian,” she added. “Several of the keynote speakers were people who had once been involved with Hydro Tasmania in some way, or were fellow Tasmanians. Some of the first wind farm developments in Australia – King Island, Flinders Island, Woolnorth – happened in Tasmania. We’re a state that’s already achieved net-zero, and have been fully powered by renewable energy thanks to our hydro-electricity and wind projects.
“It’s a special thing to share everything we’ve learned over this journey with others in the industry, and demonstrates what’s achievable when we all invest in the right areas.”
The conference provided opportunities for discussions around integration, talent pipeline, and what’s needed to phase out coal generation in favour of renewable energy sources. The magnitude of the task was laid out clearly, with social and environmental considerations, transmission challenges, and workforce challenges, however, the benefits of investing in wind power for a net-zero future are paramount.
“One of the things that stood out to me during the conference was the enormity of the mission to replace coal,” said Amanda. “The task can feel paralysing and overwhelming, but the reminder was – as this year’s theme makes clear – it can be achieved if we integrate these renewable energy sources and storage solutions.”
“Achieving net-zero won’t fall to just one type of clean energy investment – it will require a mix of technologies, skilled people, and harnessing the right opportunities as they arise. And we must do so with environment, social, and governance principles in mind and ensure we engage with stakeholders in a meaningful way,” she said.
“There are concerns in the industry around the time it can take to develop and commission a renewable energy project and, while there is an imperative to support a faster transition, we absolutely need to ensure sustainability and active community engagement.”
Andrew also explored the opportunities and challenges for the energy industry following the conference. Putting his musings in a thought leadership article, he outlined the need for a collaborative, industry-wide approach rather than a zero-sum project-vs-project approach, to meet ambitious renewable energy targets.
Additionally, acknowledging the costs of the net-zero mission, he emphasised: “this is a once-in-a-lifetime rebuilding of our electricity system into something that is more reliable than we currently have, ready for the future, and cleaner and better for our towns and communities and the wider world”.
Entura crunches the numbers to better understand Tasmania’s West Coast rainfall
This week, two of Entura’s water specialists presented at the Hydrology and Water Resources Symposium of Engineers Australia’s National Committee on Water Engineering, which was held in Sydney over 13-15 November.
Their study focused on better understanding extreme rainfall events affecting Bastyan Dam, a Hydro Tasmania dam located on the Pieman River on the West Coast of Tasmania.
“All dams need to be regularly reassessed in terms of their risk position,” said Ben James, Graduate Water Engineer. “An important part of this assessment is ensuring that the dam can withstand floods and other extreme weather events.”
“It’s vital to continually revisit our projections of rare rainfalls using contemporary methods so that we can understand whether the dam’s design and condition remain safe.”
Bastyan Dam has a catchment area of approximately 1,400 km2. It is located in the only area where the standard methods applied elsewhere in Australia to estimate probable maximum precipitation cannot be used. This is because of the uniqueness of the West Coast of Tasmania in terms of its weather patterns compared to the rest of the continent, and the sparseness of rain gauges in the region.
Without a standard method to apply, Entura’s team looked closely at the rainfalls at a number of key sites within or near the catchment where historical rainfall data was available. Together with Rory Nathan from the University of Melbourne, they applied a sophisticated statistical analysis leading to a projection of the potential rainfall and its distribution, frequency, and level of uncertainty.
“This was less straightforward than it might sound and we had to be pragmatic,” said Ben.
“We were working with data from 443 sites and gauges, some of which had been read daily and some of which provided continuous data. Some of these records extended back as far as 1880, others were from ghost towns created by the boom-and-bust cycle of mining in the area. Many sites had significant data gaps where records were missing. To maximise the amount of useable information, we processed and checked an enormous amount of data, including disaggregating multi-day rainfall totals to make them comparable to single-day totals, and assessing whether some of the incomplete datasets were still useful to include. This process required weeks of intensive work.”
“The detailed examination of historical rainfall performed for the West Coast region has increased our confidence in the outcomes of the Bastyan study, and the assessed long-term safety of the dam,” he said.
The paper presented at the Sydney symposium is the first part of a longer project. The second stage of the work involves the use of these estimates and other inputs to obtain probable maximum precipitation estimates by statistical analysis. This part of the work is nearing completion.
“We’ve just got to the point of getting results for the study,” said Ben. “This has been very exciting; following months of work to derive inputs for the analysis, we’re finally getting a feel of what the outcomes might be for the dam.”
The paper presented at the conference is Regional Rainfall Frequency Analysis for Tasmania’s West Coast, by Ben James, Prafulla Pokhrel and Rory Nathan.
Entura proudly contributes hydropower insights and expertise at World Hydropower Congress
Entura has shared valuable hydropower insights and expertise at the 2023 World Hydropower Congress in Indonesia.

The Bali Statement on Powering Sustainable Growth was released at the congress, calling for sustainable hydropower to be the backbone of national strategies to build thriving, low-carbon economies, bolstered by clean, renewable energy. It was proudly supported by both Entura and Hydro Tasmania.
Attendees included Entura’s Managing Director, Tammy Chu, and Director of Sales, Strategy and Commercial, Dr Amanda Ashworth, as well as Hydro Tasmania CEO Ian Brooksbank, and Program Manager, Battery of the Nation ESG and Approval, Donna Brown.
Tammy facilitated a panel discussion on ‘Transforming the hydropower workforce for a just transition’, which explored opportunities and challenges in securing the next-generation workforce to deliver a hydropower resurgence.
“A major challenge for the clean energy sector is ensuring that we will have enough skilled workers to enable the mammoth task ahead, while also ensuring that no one is left behind and the transition is both fast and fair,” she said.
Ian participated in a session on powering the clean energy transition in East Asia and the Pacific, which included updates and country profiles from local experts.
The World Hydropower Congress also marked the end of Roger Gill’s tenure as President of the International Hydropower Association. The baton has now been passed to former Australian Prime Minister Malcolm Turnbull.
Four key deliverables were met during the congress. These include:
- reaching consensus on policy and finance recommendations for advancing the clean energy transition to deliver COP28
- breaking down barriers to the development of renewables by advancing policy and investment-driven solutions
- demonstrating how complementary renewable technologies can be harnessed to fast-track the shift away from coal
- highlighting the immense untapped hydropower potential that exists in many regions of the world, particularly Asia and Africa.
“It was a highlight for me to meet our clients and industry peers, and create shared experiences at the congress. The hydropower industry has many challenges and opportunities that it needs to work with, and this event has helped us all to focus on the priorities and solutions,” said Amanda.

Entura power expert provides Australian perspective on energy transition to global peers
CIGRE is a global community of thousands of power systems professionals from over 90 countries. CIGRE hosts an extensive range of local and international events, fostering engagement and knowledge sharing to strengthen electrical expertise and systems across the globe.
The theme of the 2023 CIGRE Symposium was the end-to-end electricity system – including transition, development, operation and integration – and the changes that are necessary to move towards the sustainable power systems of the future.
“The overarching theme of the symposium is the urgency of the transition of our electricity systems towards net zero,” said Donald, “and it’s important that global experts pool their experiences and act decisively to overcome the technological and economic issues involved in this crucial clean energy transformation.”
Donald’s presentation provided an Australian perspective on the role of hydropower and storage technologies in supporting increased variable renewable energy, such as wind and solar PV.
“As we move from predominantly dispatchable sources of power to more variable renewable energy, there is a growing need for firming and/or storage in our power system,” said Donald.
“In the Australian context, the storage required is expected to be around 46 GW by 2050, and it is likely that conventional hydropower as well as pumped hydro and battery energy storage systems can play a role.
“My paper explored how the storage capability of conventional hydro can aid the energy transition and capture value in markets with frequent power supply surpluses and potentially shorter and less-frequent periods of deficit, given that hydro schemes can retain or delay energy release and provide much-needed flexibility in dispatch.
“There will also be a significant role for pumped hydro and battery storage in the clean energy transition. Their contribution will depend on several factors including the amount and composition of variable renewable energy relative to conventional hydropower, the level of demand in the system, and the interconnection capacity,” he said.
Donald’s analysis was based on examples from the hydropower-dominated Tasmanian power system, which has already achieved 100% renewable energy and has a target of 200% renewables by 2040. With increased interconnection to mainland Australia, Tasmania is expected to be able to provide even more clean energy and storage to support the transition of Australia’s National Electricity Market (NEM) as the country navigates the progressive retirement of the coal fleet.
“Tasmania has the potential to act as a giant battery for Australia, drawing on the flexibility, fast response and storage capacity of hydropower,” said Donald.
Entura is part of Hydro Tasmania, and is helping to deliver Hydro Tasmania’s ‘Battery of the Nation’ initiative, which aims to repurpose an aging hydropower station to operate more flexibly and to add new pumped hydro and interconnection to support the transition of Australia’s National Electricity Market.

Hydro Tasmania announces ambitious net zero targets
Hydro Tasmania, Australia’s largest generator of renewable energy, today (Thursday) announced its ambitious plan to achieve net zero reportable scope one and two emissions by 30 June 2025.
The Towards Net Zero plan involves a raft of initiatives to measure, reduce and offset emissions across Hydro Tasmania, its energy retailer, Momentum Energy, and its consulting business, Entura.
Hydro Tasmania CEO Ian Brooksbank said the company was already one of the lowest emitters in the sector, had significantly reduced emissions over the past few years, and was committed to doing even more.
“Hydro Tasmania has a proud history of sustainability, and our renewable energy is helping the State achieve its own net zero targets,” Mr Brooksbank said.
“Committing to our own journey towards net zero emissions is the next step in our story. Our action plan is redefining the way we generate, distribute, and consume electricity, so we can address the impacts of climate change and help keep our planet healthy for future generations.”
Activities to reduce emissions include replacing passenger vehicles with electric vehicles, improving energy efficiency in buildings and power stations, and reducing reliance on diesel on the Bass Strait Islands. Remaining emissions will be offset, with a priority on purchasing Tasmanian carbon credits.
Hydro Tasmania has already started the complex task of measuring scope 3 emissions, so it can devise further emission reduction strategies.
Momentum Energy, the Hydro Tasmania-owned mainland retailer, was rated 4.5 in the 2022 Greenpeace Green Electricity Guide. Its Managing Director Lisa Chiba said sustainability was an important point of difference for many consumers in choosing their electricity retailer.
“Renewable energy and sustainability are in Momentum’s DNA. We’re determined to support Australia’s drive to Net Zero by providing the education and products our customers, both large and small, need to help them reduce emissions and switch to renewable energy,” Ms Chiba said.
Managing Director of Entura Tammy Chu said the company played a unique role, taking expert skills and knowledge honed over a century on Tasmania’s hydro schemes, to the rest of the world.
“Entura works in Australia and around the world helping communities to transition to renewable energy and reduce their carbon emissions,” Ms Chu said.
Mr Brooksbank said Hydro Tasmania would continue to investigate, track and report greenhouse gas emissions and progress towards net zero, communicating openly on challenges and solutions.

Entura shares hydropower insights with India’s Prime Minister Narendra Modi
Entura’s Managing Director Tammy Chu recently shared Entura’s hydropower insights with Indian Prime Minister Narendra Modi during a Roundtable event in Sydney.
Ms Chu, who is also Vice-President of the International Hydropower Association, was one of several business leaders who took part in the 24 May event, hailing from a diverse range of industries including steel, banking, IT and tertiary education. Also present was Australian Minister of Foreign Affairs, Senator the Hon. Penny Wong.
As part of the Roundtable, Ms Chu spoke about Entura’s hydropower and pumped hydro capabilities, as well as our extensive dam safety training programs. In particular, Ms Chu referred to the dam safety work Entura is doing for India’s Central Water Commission as part of its Dam Rehabilitation and Improvement Project (DRIP).
“It was an honour to take part in this event and share Entura’s knowledge with our industry peers and government officials,” said Ms Chu. “Our partnership with Hydro Tasmania’s Battery of the Nation project gives us unparalleled insight and experience of the successful elements of major hydropower schemes and pumped hydro energy storage, which is shared across the regions in which we operate, including India.”
“During the Roundtable, I suggested that further cooperation and partnership between India and Australia would benefit both countries with our clean energy transformation, and am very hopeful that these future endeavours will be fruitful on our mutual journey to Net Zero.”
Rajeev Raina, Resident Director of Entura’s India operations, said that Entura has been working actively for 17 years in India, supporting government agencies, private developers and funding agencies across a range of hydropower projects.
“Hydropower will play a crucial role in India’s transition to clean energy,” he said, “providing benefits including baseload and peak-load supply, quick ramp-up and ramp-down rates, and greater grid stability by complementing intermittent renewables such as solar and wind.”
“For India to achieve its net zero goals, the increase in wind and solar power requires a corresponding increase in hydropower and pumped hydro energy storage, so that electricity supply can be secured without recourse to fossil-fuel-based power generation,” he said.
“The government of India has identified pumped hydro energy storage as a priority and anticipates the need for 18.8 GW of pumped storage by 2032 to integrate the new renewable capacity,” he said.
“Entura is eager to contribute our deep asset-owner experience and significant specialist skills to support India’s pathway to a more sustainable energy future.”

Entura shares training insights at 2023 International Conference on Dam Safety Management and Engineering
Entura’s Director of Strategy, Sales and Commercial, Dr Amanda Ashworth, recently took part in the 2023 International Conference on Dam Safety Management and Engineering (ICDSME23).
Amanda was one of many speakers and presenters at the 2-day event, held in Kuala Lumpur, Malaysia, by the Malaysian National Committee on Large Dams (MYCOLD). Her presentation focused on certified dam safety inspector training, and a specific collaboration between Entura’s clean energy and water institute (ECEWI), MYCOLD and Malaysia’s Universiti Tenaga Nasional (UNITEN).
“Entura’s dedicated training arm ECEWI has worked closely with MYCOLD and UNITEN to deliver a Certified Dam Safety Inspector course,” said Dr Ashworth. “During the COVID-19 pandemic, restricted travel meant that we had to find remote training options and overcome challenges to deliver the program.”
“We are proud to say that this has successfully resulted in the first batch of 29 participants receiving their certifications, which I was fortunate enough to be present for at this year’s ICDSME.”
The collaborative training program was delivered in three phases. The first involved online classes where theory on dam safety principles such as surveillance, inspection, monitoring and reporting was taught to participants by ECEWI’s key trainers in Australia. This was followed by practical site visits to two Malaysian dams, Tembat Dam and Kenyir Dam, with local supervisors. Lastly, students undertook examinations and were rewarded by successfully completing their Certified Dam Safety Inspector training.
“At Entura, we are passionate about knowledge sharing and capability building with our industry partners, and this training is representative of that. We’re looking forward to bringing through more batches of certified dam safety inspectors and delivering executive management training in the future,” said Dr Ashworth.
“Building people’s capability in engineering is required to strengthen economies, governments and individuals, and is one of the most critical elements in developing the right capacity to implement Malaysia’s dam safety guidelines and its anticipated regulatory laws.”
ECEWI has been delivering training programs and initiatives to clients and partners throughout Australia and Asia over the last decade. The institute has enjoyed close relationships with MYCOLD, UNITEN, Bangkok’s Asian Institute of Technology, Sarawak Energy Berhad and others.

Entura’s Tammy Chu promotes hydropower and clean energy in India and Brazil
Entura’s Managing Director, Tammy Chu, has shared Entura’s insights into the global renewable energy transition as part of the recent Australian Senior Business Delegation to India, led by Anthony Albanese, Prime Minister of Australia.
At the CEO Forum held during the visit, Ms Chu spoke about the need across Australia and India to build skills and capability in the renewable energy sector.
She also proposed the idea of a joint renewable energy council between the two nations, which was well received and led to an agreement that the concept will be further explored during 2023.
“With India committed to Net Zero by 2070 and with 60% of its current energy production coming from coal, there is a huge decarbonisation move underway, with plans for 500 GW of renewable energy by 2030,” said Ms Chu.
“Lowering emissions is a global challenge that can’t be solved without international collaboration,” she said.
“Forums such as this delegation to India bring leaders together to share knowledge, inspire each other, and affirm our commitment to a sustainable energy future.”
“Entura is excited by the many opportunities through which Australia can lend support to India’s renewable transition. Our teams are already working on a number of pumped hydro storage projects in Australia, and are eager to help bring about more pumped hydro projects in India, solving the grid challenges of firming wind and solar power through long-duration storage and rapid response.”
“Through Entura’s clean energy and water institute (ECEWI), we are supporting renewable energy skills development and capacity building throughout the Indo-Pacific. Developing a skilled workforce, ready to take up the jobs of the future, is a make-or-break factor for the clean energy transition.”
Ms Chu is the Vice-President of the International Hydropower Association. In that capacity, she recently participated in Latin American and Caribbean Roundtable on Sustainable Hydropower in Brazil.
“I was interested to learn of the focus in Brazil on hydropower refurbishment and upgrades, with policy and finance facilities to increase existing capacity,” she said.
“It’s easy to be drawn to new projects, but satisfying to reflect on the very long, productive lives that existing hydropower assets can have with the right stewardship.”
“Based in Tasmania, we see this combination of long-term value and new potential every day in our state’s hydropower system. For example, our teams are hard at work helping to breathe new life and flexibility into the aging Tarraleah hydropower scheme so that it can make an even bigger contribution to Australia’s National Electricity Market.”
