of the main dam’s construction work represents a significant milestone in the project’s progress. Despite setbacks faced especially over the movement restriction orders of the COVID-19 pandemic such as skilled manpower shortages, and high-water levels hampering safe work conditions, the project has clocked a series of major milestones. Commenting on the project, Datu Haji Sharbini Suhaili, Group Chief Executive Officer said: “Baleh HEP is one of Sarawak’s largest State infrastructure projects and it is Sarawak Energy’s largest hydropower project so far. Timely completion of this project by 2027 is crucial for securing the energy capacity required for future renewable demand for Sarawak and the region. We have been able to record good progress thanks to the support of the government and relevant agencies as well as the focus of our Project Delivery team and our contractors.” The diversion tunnels were safely completed In

October 2020, diverting water from upstream Batang Baleh adjacent to the confluence of the Putai River through 1.2km long dual concrete-lined tunnels running parallel to each other to allow for the construction of the main dam. Prior to the commencement of main dam works, another major milestone was reached in July 2022 when Sarawak Energy completed the package for the Jetty, Road and Bridges. Pramod said: “Meticulous planning, consideration and timely execution has led the team to this point where we are able to place the first section of rock – a critical component of the project as it means we are now beginning to work on the main dam. The movement of long lines of trucks filled with rocks of predetermined size and quality from the quarry site to the dam site will remain a significant activity over the next four years to enable safe and timely completion and commissioning of the project by 2027.” He explained: “We managed to overcome our challenges through a strong focus, resilience, and collaboration amongst the project management team working closely with our contractors China Gezhouba Group Company Limited (CGGC) and Sinohydro Corporation, and all our stakeholders including
local authorities and community. We were able to re-strategise and quickly make the necessary changes to adapt to the ever-changing environment and to maintain our momentum.”
New orders With regards to proejcts in development, Andritz
recently announced it has received an order from CH Karnchang (Lao) Company Ltd to supply the electro- mechanical equipment for the newly constructed Luang Prabang run-of-river hydropower plant in Lao People’s Democratic Republic. Commissioning is scheduled for the end of 2029.
Andritz’s scope includes design, manufacturing, supply, transportation, erection, testing and commissioning of seven large Kaplan turbine-generator units (203MW each), and three smaller units (18MW each) including transformers, governors, control, excitation and protection and SCADA systems, as well as the electrical power and associated auxiliary systems. With a nominal capacity of 1470MW, the Luang Prabang plant will have an annual output of about 6500GWh and will provide renewable energy to Thailand’s electricity network. The state-of-the art turbine-generator units will also feature oil-less turbine runners and a fish-friendly design.
Back in December, the Heavy Civil Infrastructure Business of Larsen & Toubro secured an order from renewable energy firm Greenko group for development of an off stream pumped storage project in Madhya Pradesh, India. A consortium led by Larsen & Toubro is to
execute the civil and hydromechanical works of the Gandhisagar Pumped Storage Project under a stringent timeline of 30 months. Upon completion, the project will be one of the
largest clean energy projects of its kind in India. It envisages creation of an upper reservoir near Khemla block village while the existing Gandhisagar reservoir will be the lower reservoir. The project involves constructing an upper dam, intake structure with approach channel, steel lined buried penstock/ pressure shaft (vertical & horizontal), surface powerhouse, draft tube tunnel, tailrace outlet structure and tailrace channel.
Working with other renewables In December, members of the community of Thailand’s
Khon Kaen Province attended a public hearing on plans for a hydro-floating solar hybrid project at Ubol Ratana Dam. The meeting was held by The Electricity Generating Authority of Thailand (EGAT) and Consultant of Technology Co., Ltd. (COT) and was chaired by Mr. Sutep Maneechot, Vice Governor of Khon Kaen Province. Sutep Maneechot said that this project, which will generate electricity from clean energy by combining floating solar panels with hydropower, will become a learning center for renewable energy and a new tourist destination in Khon Kaen Province. The project will enhance power system security at the regional level as well as reduce carbon dioxide emissions. During the meeting, Ms. Duangkamol
Phaprommarat, a COT environmental specialist shared the project details, environmental impact assessment, and measures to prevent, solve, and monitor environmental impact in order to build understanding
