India as a major stake holder in Mangdechhu project has initiated one of the ten Hydroprojects planned by Bhutan to generate 10,000MW hydropower by 2020 which will drive the hydro turbine market over the forecast timeline.
INDIA: India as a major stakeholder in the Rs 4000 crore worth green power project that is planned to supply mammoth amount of energy to India at a favorable price. Initially, the project was supposed to get completed in 2017, the project was set to get commissioned in the month of June 2018. Following few minor technical complicacies, the commissioning was shifted to January 2019.  A.K. Misra- The Managing Director (Mangdecchu Hydroelectric Project Authority) said “One of the main issues that caused the delay was a small crack in a floodgate that the authority did not want to ignore. All the works are now likely to be over soon and all the four units of the project plant are expected to start producing with all its units by the end of February 2019”.The 720 MW project, comprising four units of 180 MW each, is expected to export 3 billion units of green power to India every year at mutually agreed per unit tariff of Ngultrum 4.12, equivalent to INR 4.12.  According to BlueWeave consulting,  In light of the current emphasis being placed, it may surprising that hydropower is the world’s largest source of renewable energy and is likely to remain so well into the future. Global power demand is also pushing the market forward and is expected to increase from around 21.7 million Gigawatt hours (GWh) in 2017 to over 27 million GWh by 2025. Meeting this demand will require an increase in the pace of capacity additions in order to fulfill peak demand requirements, meet emission control, and provide affordable power. Although electricity demand varies from country to country, they are generally focused on building base load plants. In aspect to that, India is about to invest into a huge Hydro project in collaboration with Bhutan to generate 10,000MV hydropower. This 720 MW project has four units of 180 MW each which will export 3 billion units of green power to India every year at a rate of INR 4.12. Indo-Bhutan bilateral agreement for this project on Himalayan river  Torsha with its origin in Tibet was signed in April 2010, construction began in 2012. The cost of Mangdechhu project was around INR 2900 crore that was revised to over 4500 crore afterward. Lion’s share of that is funding from India in the form of 30% as grant and 70% loan. The project is estimated to generate 2,923GWh of green electricity while contributing 2.2 million ton of CO² offset per year from atmosphere.  The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesn't necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine. Another type of hydroelectric power plant - called a pumped storage plant - can even store power. The power is sent from a power grid into the electric generators. The generators then spin the turbines backward, which causes the turbines to pump water from a river or lower reservoir to an upper reservoir, where the power is stored. The hydro turbine is the crucial equipment for Hydro Electricity market which is strongly driven by several factors, such as increasing demand for energy on a global scale, rise in the demand for cleaner technologies for power production, stringent emission policy targets, etc. Thus, development of Small Hydropower Plants is further expected to create opportunities for the companies engaged in the manufacturing of hydro turbine and hydro power plant equipment. According to BlueWeave consulting’s upcoming report, Titled-“India Hydro Turbine Market, By Technology (Reaction,Impulse), By Capacity (Small-Sized >1MV, Medium-Sized Hydro 1-10MW,Large-Sized =<10MW ), By Configuration(Spiral Casting, Multistage)By Key Company Players, By Region (North, South, East, West); Size and Forecast, 2014-2025,” Hydropower turbines are the workhorses of the facility and may need rehabilitation, replacement or cavitation repair. In addition, fish-friendly hydro turbines are being developed and installed. The rapid growth of variable renewable energies (VRE) in the recent years is increasing the need for rapid-response energy storage technologies. The landscape for grid-scale energy storage is evolving, from being almost exclusively supplied by pumped-hydropower storage, to include various new technologies. Of these, battery storage is evolving and growing at a rapid pace, even as pumped hydropower storage continues to supply over 95% of energy storage requirements worldwide. In 2016, about 6.4 GW of pumped storage capacity came online, nearly twice the quantity installed in 2015. The above-mentioned factors are responsible for the growth in the global hydro-power sector. The hydro-power industry, being the biggest end user of hydro turbines, has witnessed a significant growth in the recent years. Further, the development of innovative technologies is expected to help reduce costs and improve both hydro power production efficiencies and environmental performance.
