Entura develops Pumped Hydro Atlas of Australia
Specialist power and water consulting firm Entura has been engaged by Hydro Tasmania to develop a practical atlas of pumped hydro energy storage opportunities to support development of dispatchable renewable energy generation.
The atlas has already been applied to inform and enable Hydro Tasmania to shortlist potential pumped hydro sites for the ‘Battery of the Nation’ program in Tasmania. Completed in October 2017, the Pumped Hydro Atlas of Australia identified more than 5000 unique potential sites across Australia’s National Electricity Market (NEM) to enable greater penetration of renewables in the country.
“The Pumped Hydro Atlas of Australia produced by Entura is a real-world, relevant resource informing future project development,” said Dale Bryce, Entura’s Director of Customer Strategy and Market Development. “To determine the best possible sites, our analysis took into account not only topographical suitability, but also considered all the practical factors involved in creating a viable and successful project.”
Following an exhaustive process, twenty promising sites were shortlisted for different states with a desktop review of geology, high-level engineering arrangements, and approvals requirements. For each site a map was prepared including locality, land use, planning zones, and key characteristics of the potential project.
Mr Bryce explained that pumped hydro energy storage has the potential to generate rapid response, flexible power for delivery into the NEM. “It’s a highly efficient form of large-scale energy storage that could help mitigate challenges that may come with the introduction of more renewables into the market.”
“Overlaying the outputs of this atlas with any new wind and solar development across the NEM could identify viable dispatchable renewable energy generation hubs with the potential to replace retiring thermal generation assets.”
Entura has completed the Technical Feasibility Study for Genex Power’s Kidston Pumped Storage Hydro Project in Queensland and is currently supporting pumped hydro project proponents in South Australia, as well as continuing to support the ‘Battery of the Nation’ program. The firm has also been involved in a number of wind, solar and hybrid renewables projects in Australia and internationally, supporting development, grid integration and connection studies.
Entura has worked with clients in more than 30 countries over the past few decades – including India, Laos, Malaysia, Papua New Guinea, South Africa and Uganda – assisting with developing, operating and maintaining hydropower assets of all sizes.

Marshall Islands turns to Entura for renewable energy solutions
Specialist power and water consulting firm Entura has been engaged by the Asian Development Bank to deliver renewable energy strategic advice and solutions to help the Republic of the Marshall Islands to achieve its renewable energy target.
The Marshall Islands is a sprawling chain of volcanic islands and coral atolls in the central Pacific Ocean, between Hawaii and the Philippines. Like many island nations in the Pacific, the Marshall Islands is facing the challenges of climate change, which is the greatest threat to its low-lying atolls and to its people.
As part of its National Energy Action Plan, the country has a target of 20 per cent renewable energy generation by 2020 to reduce its reliance on diesel fuel and foster its transition to clean energy.
“Energy security and self-sufficiency are essential for remote locations such as the Marshall Islands,” said Entura’s Managing Director, Tammy Chu. “Diesel fuel remains the single largest expense to generate power in these remote locations, so using renewable energy makes good economic sense.”
Entura is working closely with The Marshalls Energy Company (MEC) to assist it to meet the nation’s renewable energy target. Funded by the Asian Development Bank (ADB), the work has three streams of activity: review of the local power system and preparation of an investment implementation master plan; review of financial management practices and tariff structures; and capacity building.
“We will initially undertake a thorough assessment of the entire power system assets to identify any immediate improvements and efficiency gains and to define pathways to achieving 20 per cent renewable energy penetration into the network,” explained Dusan Nikolic, senior electrical engineer at Entura.
“Once we determine if additional generation or enabling technologies are required, we will assess their feasibility and provide recommendations for implementation.”
Following this phase Entura will review MEC’s financial management systems and practices and its capacity to comply with ADB funding requirements. The audit will also assess cost structures to identify potential efficiency improvements and review tariff structures to recover costs. This will include a poverty impact analysis of proposed changes in the electricity tariff structure to help mitigate impacts of any residential tariff increases on the poor.
The third stream of work, capacity building and institutional strengthening, is a key output of the project. Mr Nikolic said that developing practical training for local operations and maintenance workers to enhance their ability to manage the day-to-day operation of renewable energy systems both now and into the future is fundamental for MEC’s long-term success.
“Our training program will focus on improving the capacity and capability of those responsible for operating and maintaining the assets and those tasked with assessing the viability of potential projects, procurement, and the financial management systems and tariff structures.”
Delivered by the Entura clean energy and water institute, training will include power system modelling, procurement methods and process, and enhanced financial systems.
The project is expected to be completed by the end of 2017.
Entura has developed a world-leading approach to off-grid and fringe-of-grid megawatt-scale development through its experience with hybrid off-grid systems and remote area power systems projects. The firm works with utilities, mining companies and remote communities as an independent advisor or implementation partner across the full lifecycle, from concept development to system operation.
Integrated water management system takes top environmental engineering award
Specialist power and water consulting firm Entura, Tasmanian Irrigation and Water Solutions Pty Ltd won the Environmental Engineering Excellence Award for the Meander Dam integrated water management system at the 2016 Australian Engineering Excellence Awards in Brisbane last night.
Hosted by Engineers Australia, the Australian Engineering Excellence Awards seek to identify, recognise and reward outstanding achievement in the practice of engineering and service to the profession, promoting industry excellence across engineering projects and engineering professionals.
The Environmental Engineering Excellence Award recognises achievement in sound environmental practice and in the sustainable use of natural resources. It also recognises the significance of the work as a benchmark of Australian environmental engineering and the extent to which the work represents best practice in environmental engineering.
Designed, developed and delivered by Entura, the Meander Dam integrated water management system provides accurate, reliable and easy-to-use information to help Tasmanian Irrigation (TI) effectively manage its Meander Dam water storage and associated hydropower facility in northern Tasmania. The system allows TI to deliver certainty of irrigation supply to water users while also optimising power production, and ensuring dam safety.
“We’re delighted to have partnered with Entura to develop the Meander Dam integrated water management system and are thrilled about winning this national award,” said TI CEO Nicola Morris.
“The value created by the water management system was particularly evident during the 2015–16 irrigation season, in which the region experienced below-average rainfall that resulted in reduced inflows into Meander Dam and increased demand for water supply to irrigators.”
“We were able to match demand from predicted storage levels, fulfilling irrigator expectations and retaining sufficient storage capacity to be able to extend the delivery for an additional month. This ensured that irrigators were able to finish final crops and also maintain pasture growth for livestock and dairy activities.”
Meander Dam is the centrepiece of the Meander Valley Irrigation Scheme, one of the largest irrigation schemes in Tasmania. The dam was completed in 2007 and holds 43 000 megalitres of water, supplying five irrigation regions servicing pasture and cropping land.
Complexities of the energy-water nexus a challenge for utilities
“Real-time data and models are critical for utilities facing the challenges of the energy-water nexus,” said David Fuller, Principal Consultant Water Management and Technology at Entura. “These tools allow operations to maximise the value of water whilst balancing the demands of electricity generation or use.”
“The Meander Dam integrated water management system is an information gathering and processing system, as well as an easy-to-interpret, customised decision-support platform for optimising management and control of an integrated irrigation and hydropower system.”
Powered by Entura’s own Ajenti™ Data Management System, the solution developed for TI harnesses real-time rainfall and flow monitoring data captured by a network of catchment telemetry, and integrates this information with short-term and long-term forecasts from the Bureau of Meteorology and a hydrological model of the catchment.
Through a user-friendly dashboard interface, TI has an up-to-date picture of the dam’s status and the probability of various possible short-term and long-term scenarios of storage level and hydropower output.
Real-time information from water meters on pumps within the irrigation area is also brought into the system to give the operator a complete water balance in the area fed by the dam.
Ms Morris said that access to such robust and reliable information supported appropriate management decision making, such as whether and when to release water, and the extent and timing of hydropower operation.
“Increased hydropower operation reaps a dual benefit from the water resource, helping to offset our operational costs, enabling greater delivery of service throughout Tasmania, benefitting not only the local community but the whole Tasmanian agricultural sector,” said Ms Morris.
Entura works with customers across the Asia-Pacific region and Africa to help them improve the safety and performance of their dams, irrigation schemes, pipelines and pumping stations and to deliver innovative data monitoring, management and analysis solutions.
Entura completes Kidston Pumped Storage Hydro Project Technical Feasibility Study
Specialist power and water consulting firm Entura has completed the Technical Feasibility Study (TFS) for Genex Power’s Kidston Pumped Storage Hydropower Project in North Queensland, Australia.
The TFS concludes that all of the key risks identified at the pre-feasibility stage, and any additional risks identified during the study, have been appropriately mitigated or addressed through detailed design augmentation and optimisation undertaken by Entura and project partner HydroChina.
“Much of the work undertaken by Entura was focussed on optimising the project to achieve a design which is technically and commercially feasible,” said Genex Power Managing Director Michael Addison.
“Following a thorough investigation, a preferred configuration has been determined and the project is now fully designed from a technical feasibility perspective, including the civil works program and detailed mechanical equipment specifications.”
Entura Project Director and Principal Consultant, Civil Engineering Richard Herweynen said that a number of project size options ranging from 200 MW to 450 MW were developed as part of the TFS.
“Following detailed market studies undertaken by Genex and its financial consultants to assess the pricing and revenue impacts of the various options considered, it was determined that a 250MW scheme with six hours of continuous generation, totalling 1,500 MWh of energy storage capacity, would be the optimal size,” explained Mr Herweynen.
“Pumped storage hydropower has the potential to generate rapid response, flexible power for delivery into the National Electricity Market. It is a highly efficient form of large-scale energy storage that could help mitigate challenges that may come with the introduction of more wind and solar power into the market.”
Genex and Entura continue to engage with a number of highly experienced and well recognised EPC Contractors and Generator/Turbine Suppliers to develop the anticipated capex estimates. Formal competitive tender processes will be undertaken over the course of the next phase of the project development.
The Australian energy market has evolved significantly since the initial inception of the Kidston Pumped Storage Hydropower Project. Further significant evolution in the market is expected as generation mixes shift from traditional fossil fuel generation towards increases in large scale renewable energy generation.
There is a critical need for large scale energy storage, at an affordable cost, to balance the penetration of large scale renewable energy generation into Australia’s National Electricity Market.
Pumped storage hydropower projects are a natural fit in an energy market with high penetration of renewable energy as they help to maximise the use of the renewables that are subject to the vagaries of the weather. Pumped storage provides a load when the wind is blowing and the sun is shining, and it also provides a source of energy when the sun has set and the wind has dropped.
Entura has worked with clients in more than 30 countries over the past few decades – including India, Laos, Malaysia, Papua New Guinea, South Africa and Tajikistan – assisting with developing, operating and maintaining hydropower assets of all sizes. The firm has also been involved in more than 100 advanced and operational wind farm projects in Australia and internationally, supporting development, renewables grid integration and connection studies.
The full ASX announcement about the completion of the TFS is available here.

Entura completes Suma Park Dam upgrade in New South Wales
Specialist power and water consulting firm Entura has recently completed the Suma Park Dam upgrade in New South Wales, Australia, after developing an innovative solution to increase the height of the dam wall by three metres while maintaining regular operations.
Suma Park Dam is a 30.5m-high single-curvature concrete-arch dam near Orange, central New South Wales. Entura was engaged by Orange City Council in 2010 to develop a risk-based concept design to address the dam’s known spillway deficiency, and explore its uncertain seismic stability. Increasing storage at the dam to firm up the yield from its integrated water supply system was also a key objective for the council.
In 2013, the concept design developed by Entura was accepted by Orange City Council and the NSW Dam Safety Committee, allowing the project to proceed. Subsequent works undertaken by Entura included detailed design, environmental studies and approvals, and preparation of tender documentation.
Led by Entura’s Specialist Dams Engineer Paul Southcott, the innovative design process involved the project team creating a computer model of Suma Park Dam that allowed the design solution to be developed and assessed prior to implementation.
“A ‘water load’ or pressure was applied to the 3D design model allowing us to calculate the stress in the concrete wall, so when it came to the real thing we knew how to strengthen it to make it safe,” said Mr Southcott.
“The solid concrete dam wall actually deflects, although it is too small to see it,” added Mr Southcott. “As the water load changes, the deflections are very small and the computer models could show us that deflection.”
Mr Southcott explained that his team identified a logical staging of remedial works that allowed Orange City Council to spread the capital cost over two or more years to help manage its budget. Additionally, Entura’s recommendation to revise the flood hydrology resulted in a significant reduction of the physical scope of works required to bring the dam up to standard. Careful modelling of the dam under seismic loading demonstrated that no seismic upgrade was required.
During the construction phase, undertaken by civil contractor Geotechnical Engineering, Entura provided construction support as Owner’s Engineer. Precast parapet wall slabs were designed and built away from the dam wall and then brought in and placed on top of the existing dam wall in order to increase the height. A wheeled crane was used to place one piece and secure it, then it would drive along that piece to place the next piece, 87 times until all of the concrete slabs were secured.
The $18 million dam wall upgrade was officially opened last Friday by Mayor John Davis OAM and NSW Government Duty MLC for Orange, Sarah Mitchell.
As part of Hydro Tasmania, Australia’s largest renewable energy producer and water manager, Entura draws on more than 100 years of experience of planning, building, managing and maintaining the many dams of Tasmania’s hydroelectric power system.
Entura has undertaken detailed design for many of Australia’s key new dam projects over the past decade, including Wyaralong Dam and Bromelton Offstream Storage in Queensland, the Samson Brook Pipehead Dam in Western Australia, the enlarged Cotter Dam in the ACT, and the Meander Dam in Tasmania.
Entura and Tasmanian Irrigation win Australian Engineering Excellence Awards
Specialist power and water consulting firm Entura, Tasmanian Irrigation and Water Solutions won the Australian Engineering Excellence Awards (AEEA) Tasmania 2016 in the category ‘Control Systems, Networks, Information Processing and Telecommunications’ for the Meander Dam integrated water management system.
Presented during a gala event in Hobart last night, the AEEA Tasmania 2016 Awards seek to identify, recognise and reward outstanding achievement in the practice of engineering and service to the profession, promoting industry excellence across engineering projects and engineering professionals.
Designed, developed and delivered by Entura, the Meander Dam integrated water management system provides accurate, reliable and easy-to-use information to help Tasmanian Irrigation (TI) effectively manage its Meander Dam water storage and associated hydropower facility in northern Tasmania. The system allows TI to deliver certainty of irrigation supply to water users while also optimising power production, and ensuring dam safety.
“We’re delighted to have partnered with Entura to develop the Meander Dam integrated water management system and are thrilled about winning such a prestigious award,” said TI CEO Nicola Morris.
“The value created by the water management system was particularly evident during the 2015–16 irrigation season, in which the region experienced below-average rainfall that resulted in reduced inflows into Meander Dam and increased demand for water supply to irrigators.”
“We were able to match demand from predicted storage levels, fulfilling irrigator expectations and retaining sufficient storage capacity to be able to extend the delivery for an additional month. This ensured that irrigators were able to finish final crops and also maintain pasture growth for livestock and dairy activities.”
Meander Dam is the centrepiece of the Meander Valley Irrigation Scheme, one of the largest irrigation schemes in Tasmania. The dam was completed in 2007 and holds 43 000 megalitres of water, supplying five irrigation regions servicing pasture and cropping land.
“The Meander Dam integrated water management system is an information gathering and processing system, as well as an easy-to-interpret, customised decision-support platform for optimising management and control of an integrated irrigation and hydropower system,” explained Angus Swindon, Power and Water Director at Entura.
Powered by Entura’s own Ajenti™ Data Management System, the system harnesses real-time rainfall and flow monitoring data captured by a network of catchment telemetry, and integrates this information with short-term and long-term Bureau of Meteorology forecasts and a hydrological model of the catchment, using the OPSIM modelling system developed by Water Solutions.
Via a user-friendly dashboard interface, Tasmanian Irrigation has an up-to-date picture of the dam’s status and the probability of various possible short-term and long-term scenarios of storage level and hydropower output.
Real-time information from water meters on pumps within the irrigation area is also brought into the system to give the operator a complete water balance in the area fed by the dam.
“Access to such robust and reliable information supports appropriate management decision making, such as whether and when to release water, and the extent and timing of hydropower operation,” said Ms Morris.
“Increased hydropower operation reaps a dual benefit from the water resource, helping to offset our operational costs, enabling greater delivery of service throughout Tasmania, benefitting not only the local community but the whole Tasmanian agricultural sector.”
Entura works with customers across the Asia-Pacific region and Africa to help them improve the safety and performance of their dams, irrigation schemes, pipelines and pumping stations and to deliver innovative data monitoring, management and analysis solutions.
Chanju-I hydropower project set to commence operations
I A Energy and specialist power and water consulting firm Entura today announced the conclusion of the 36 MW Chanju-I run-of-river hydropower project in Chamba, Himachal Pradesh, India.
The milestone was announced during a hydropower roundtable hosted by the Australian Trade and Investment Commission in New Delhi, attended by Tasmania’s Minister for Energy, Matthew Groom; representatives of the Ministry of Power, Government of India; and members of the private sector.
The participation of the private sector in generation, transmission and distribution of electricity in India was approved in 2005. Chanju-I was awarded to I A Energy through a competitive bidding process and the business engaged Entura in 2007.
“This is a very important moment for us at I A Energy as Chanju-I was our first step towards diversifying into the renewable energy sector,” said I A Energy Managing Director Narendra Goel.
“We’re very pleased to have worked with Entura to develop a safe, cost-effective and sustainable run-of-river hydropower station that will support India’s need for new renewable electricity supply.”
Entura’s involvement over the full cycle of the project helped I A Energy ensure the right location, access and water availability for a viable project. The firm developed an effective design for the project, ensured its progress through development approval, and played an ongoing role during construction.
“Chanju-I is a very special project as we have been involved with it since its inception, and today we are delighted to be celebrating its completion,” said Entura India’s Managing Director.
“We are very proud of having supported the successful entry of a private sector player in India’s hydropower market, which will certainly inspire others that might be considering renewable energy but don’t have the expertise.”
“Chanju-I demonstrates the extensive hydropower experience and skills of our teams in India and Australia, which enabled I A Energy to overcome a number of challenges throughout the different phases of the project, delivering valuable outcomes such as increasing the asset capacity from 25 MW to 36 MW.”
The project involved construction of a 16-metre high barrage, a 4.1 km head race tunnel, two underground desilting chambers, underground pressure tunnels, pressure shafts and a surface power house. Entura provided technical expertise in optimising design and construction, costing, contract packaging, selection of equipment, scheduling and project management.
