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.

Specialist power and water consulting firm Entura has been engaged by The Renmark Irrigation Trust (RIT) to deliver telemetry technology that will enable better data collection and management from over 800 water meters in South Australia.
Founded in 1893, RIT is Australia’s oldest irrigation scheme. It supplies irrigation water pumped from the Murray River to over 550 farming properties, covering more than 4,500 hectares of horticultural land.
The new system will significantly improve customer experience and drive operational efficiencies, eliminating the need for contractors to manually read the meters.
“We recognise the importance of good irrigation delivery and on‐farm practices through the use of efficient delivery infrastructure systems and efficient water use, monitoring and management techniques,” said RIT General Manager, Barry Schier.
“The new telemetry system provided by Entura will capture water use data from individual mag flow water meters utilising RS232 protocol throughout our scheme and integrate that data with our existing billing and water orderings systems.”
“Our customers will be able to access information concerning their daily water use and remaining water allocation via the internet, giving them greater oversight of their water use patterns and providing more flexibility for water trading.”
Upon implementation, RIT will take ownership of the entire system so that it can operate and maintain it with little or no external assistance. Entura will support the required knowledge transfer and capability development through its training division, the Entura clean energy and water institute.
Financial support for the RIT project was provided via a grant received under Round 2 of the Irrigation Industry Improvement Program (3IP) which forms part of the South Australian River Murray Sustainability (SARMS) Program funded by the Australian Government and administered by Primary Industries and Regions South Australia (PIRSA).
“We’re pleased to be partnering with RIT to deliver a data collection and management system that will allow them to just concentrate on the data itself, and use it to manage risks and get the best out of their operations,” said Entura’s Business Development Manager for Water.
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.
As part of Hydro Tasmania, Australia’s largest water manager, Entura is backed by more than 100 years of planning, building, managing and maintaining water assets.

Innovative pumped storage hydro design by Entura beats expectations
Specialist power and water consulting firm Entura has developed an innovative design for Genex Power’s Kidston Pumped Storage Hydropower Project in North Queensland, Australia.
Following an extensive project optimisation process, Entura and project partner HydroChina produced a design that has the potential to increase the plant’s head and peaking generation capacity of the project to a maximum of 450 MW over a 5-6 hour period, beating earlier expectations.
“The new design provides the lowest cost per MW of installed capacity and presents the lowest operating and environmental risk,” said Genex Power Managing Director Michael Addison. “Clever thinking and commercial focus has delivered an optimal design solution to maximise the potential of our project.”
Project Director and Principal Consultant, Civil Engineering at Entura, Richard Herweynen, said significant studies and investigations have been undertaken over the past months to provide confidence around this solution.
“Our new design, which provides for a low turkey’s nest dam design for the upper reservoir located on the top of an old waste rock dump, was developed through a detailed options assessment and optimisation process,” explained Mr Herweynen.
“This new configuration incorporates several strategic advantages and removes a number of the previous constraints inherent in the initial concept and, most significantly, enables a substantial increase in the installed capacity of the project from the initial 330 MW to up to 450MW, which is a fantastic outcome for our client.”
The Kidston Pumped Storage Hydropower Project is being developed at the disused Kidston Gold Mine in North Queensland and the feasibility study phase is being supported by the Australian Renewable Energy Agency (ARENA). There are currently only three pumped storage hydro schemes in Australia.
Pumped storage hydropower has the potential to generate rapid response, flexible power for delivery into Australia’s National Electricity Market (NEM). 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 NEM.
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.
