Indian contract Another company that has recently been awarded
a contract on a major hydropower facility is Bharat Heavy Electricals Limited (BHEL). The company said it will be supplying and commissioning the Electro-Mechanical (E&M) components of the largest hydropower project in India – the 2880MW Dibang Multipurpose Project in Arunachal Pradesh. The contract for this 12x240 MW hydropower
endeavor, located in Roing within the Lower Dibang Valley district of Arunachal Pradesh, has been awarded to BHEL by the National Hydroelectric Power Corporation (NHPC) following an international competitive bidding process BHEL’s role under the contract involves several critical tasks, including the design, engineering, manufacturing, supply, installation, and commissioning of the electro-mechanical package. This package encompasses a wide range of components such as Turbines, Generators, Digital Governing Systems, Static Excitation Systems, Transformers, Bus Reactors, Gas Insulated Switchgear, Outdoor Pot Yard & Switchyard Equipment, as well as Electrical & Mechanical Balance of Plant (BoPs).
Major components necessary for the Dibang Multipurpose Project will be manufactured in BHEL’s facilities located in Bhopal, Bengaluru, Jhansi, and Rudrapur. Simultaneously, the execution and assembly work on-site will be managed by BHEL’s Power Sector - Eastern Region division, based in Kolkata. This latest contract emphasizes BHEL’s long- standing partnership with NHPC, which spans more than four decades, beginning with the commissioning of the first project, Bairasul (3x60MW), in 1981. In addition to this achievement, BHEL is actively working on other ongoing projects, including the 850MW Ratle Hydropower Project in Jammu and Kashmir, handling limited E&M works, and the renovation and modernization of the 105MW Loktak Hydropower Project in Manipur.
Mini hydropower
A consortium comprising PT Andritz Hydro of Indonesia and Andritz Hydro Private Limited from India has signed a contract for the Merangin mini hydropower plant located in Jambi Province, Indonesia. This marks the consortium’s third collaboration with the Bukaka Group, following the successful completion of the Cikandang
and Cikaengan-1 mini hydropower projects in 2021 and 2022. The Merangin mini hydropower plant, known as HPP Merangin, is designed to include a 3.199 MW horizontal Francis unit that will make use of the flow discharge from the 350 MW Kerinci Merangin HEPP, also under development by the Bukaka Group. Under the contract, Andritz is responsible for the supply of the turbine-generator package and the control system. The execution of the Merangin mini hydropower plant will be carried out by specialists from Andritz in India and Indonesia.
First of its kind RheEnergise, a UK clean-technology company
specializing in long-duration energy storage solutions, has recently taken a significant step forward in its mission to revolutionize the energy storage landscape by signing a key manufacturing contract with Turkish engineering firm, Hydropower Engineering (HPE). This collaboration marks a pivotal moment for the development of RheEnergise’s HD Hydro® technology. Under this partnership, HPE will undertake the manufacturing of RheEnergise’s inaugural 500kW HD Turbine™. This turbine is set to be a central component of RheEnergise’s long-duration energy storage demonstrator project, to be constructed near Plymouth, Devon, in the United Kingdom. The HD Turbine™, the first of its kind, will be delivered during the first quarter of 2024. RheEnergise’s demonstrator project has garnered support from the UK Government through the Longer Duration Energy Storage (LoDES) Demonstration Programme, a vital component of the UK Government’s £1 billion Net Zero Innovation Portfolio (NZIP). The LoDES initiative is designed to expedite the commercialization of low-carbon technologies and systems. What sets RheEnergise’s HD Hydro technology apart is its scalability, cost-effectiveness, and rapid deployment capabilities, said the company. Unlike conventional hydro-power systems, it employs an environmentally friendly fluid that is 21
/2 times denser
than water, resulting in a substantial power boost. This innovative approach enables the deployment of HD Hydro on hills, removing the geographical constraints associated with traditional mountain- based hydropower systems and creating significant opportunities both in the UK and worldwide.
