Meeting peak summer power demand is emerging as big challenge. Ministry of Power (GOI) has implemented following proactive measures to meet the peak evening power demand of 224 GW during April 24 : 1.Optimizing capacity of imported-coal based power plants. 2.Shifting planned maintenance of power plants to the monsoon season. 3.Encouraging generation companies to maintain plant health for full capacity. 4.Revival of thermal plants under long outage. 5.Optimizing hydropower generation for an extra 4 GW. Expected peak demands 235 GW (day) & 225 GW (evening) in May and 240 GW (day) & 235 GW (evening) in June.To meet this stretched demand,additional steps being taken as: 1.Utilizing full capacity of gas-based power plants, providing an additional 6 GW. 2.Optimizing hydropower generation for an extra 4 GW. 3.Minimizing outages and strategically shifting maintenance of thermal plants(additional 5 GW). 4.Anticipated increase in wind power generation (4- 5 GW). Fingure are crossed that everything must be as per plan & most importantly " Monsoon should be on time & above average"

Just published in #Journal of #Fluids and #Structures our latest paper: "Numerical study of the effect of a ridge on the wake and loading of a tidal stream turbine" freely available at https://lnkd.in/dqynRC9r Here we did a systematic analysis of where is best to place a turbine relative to a ridge, a bed feature that is widely found at energetic tidal sites such as #MeyGen. Results are evident: a ridge plays a significant role in the wake recovery downstream of a turbine and it also introduces a source of turbulence (high and low frequency) that impacts turbine loading. You also would not want to place your beloved turbine in the ridge's recirculation!! Excellent paper led by Sulaiman Hurubi, supervised by Tim Stallard, Peter K Stansby and myself in collaboration with Hannah Mullings, MEng PhD CEng MIMechE FHEA. Below is a video of the turbine's wake centre for one of the positions studied. Thanks EPSRC, Supergen Offshore Renewable Energy (ORE) Hub and #UKTC for supporting this research.

Ever wonder how hydropower is generated? Since this month is the 40th anniversary of KRCD’s hydroelectric power plant, we thought we’d use this opportunity to teach you how the Jeff L. Taylor Power Plant produces clean energy! 💡💧 Coming from the Sierra Nevada mountains, the Kings River fills Pine Flat Reservoir and flows into the hydroelectric turbines through large diameter pipes (technically called Penstocks; in our case each unit has a 13.5 feet diameter penstock) into our power plant. That flowing water puts pressure on the turbines causing them to rotate as it passes through. As a result, a generator connected to the rotating turbine produces electricity! To operate the hydroelectric power plant and produce electricity, KRCD holds a Federal Energy Regulatory Commission (FERC) license. Obtained in 1979, this FERC license expires in 2029, but KRCD staff are already preparing to renew the license today to continue operating the power plant without interruption for decades to come! #Hydropower #KingsRiver #PineFlat

Construction of mini hydroelectric power plant with two Francis turbines - YouTube https://lnkd.in/gnK87iAZ This is a simple demo on Mini (micro) Hydro Electric Power Generation. In Indonesia, during mid 90s and later, much talk was going on about constructing numerous mini hydros with the help of Canadian support. Wherever possible a tailor made or well standardized mini plants in every country can be thought of with a view of mini-loop grids. Some excellent ideas can be drawn from the simple demo shown here.

Next step will be the installation of the pump drive system on surface, consisting of our powerful variable frequency drive ElektroMotion smartDRIVE and step-up transformer, followed by commissioning of the complete pump system. Once the new 4 MWth deep geothermal plant is in operation, it will supply clean geothermal energy for up to 5,000 households in Potsdam.   #GeoDynamics #OilDynamics #TKP #SubmersiblePump #Geothermie #TiefeGeothermie #Wärmewende #ArtificialLift #Energie #Energy #Geothermal #Erdwärme #Aardwarmte

A fantastic depiction showcasing how dams utilize the working principle of hydroelectric power! hydroelectric power is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water. Hydropower relies on the endless constantly recharging system of the water cycle to produce electricity using a fuel water that is not reduced or eliminated in the process. There are many types of hydropower facilities though they are all powered by the kinetic energy of flowing water as it moves downstream. Hydropower utilizes turbines and generators to convert that kinetic energy into electricity which is then fed into the electrical grid to power homes, businesses, and industries.

Sources of solar tracking errors and correction strategies for heliostats 𝗛𝗶𝗴𝗵𝗹𝗶𝗴𝗵𝘁𝘀 ⬇ 🔹 The solar tracking error sources of heliostats in #CSP tower plants are reviewed. 🔹 The state of the art for analyzing and correcting error sources is presented. 🔹 Gravity and wind loads, creep, rainfall, and soil properties cause the most errors. 🔹 Spot deviation depends on the error magnitude, heliostat position, and season. 🔹 Mathematical model-based solar tracking corrects most errors. https://lnkd.in/d3YscrEa #CSP #solar #thermal #concentrated

As offshore wind turbines (floating type, for example) gets larger to maximize LCOE per turbine unit, production quality becomes a challenge that bites even the most established manufacturers, such as GE Vernova. https://lnkd.in/gQFFdmuG Meanwhile in South Korea, a recent technical study concluded the advantages of using bladeless turbines, under different wind speed conditions. Key-takeaway of the technical study: - wind passing through a cylinder body causes pressure difference between two regions translating into vortex-induced vibration. - novel method to tune the vibrational resonance of the turbine to allow for a large operating wind speed, substantially increasing the efficiency of such type of design when compared against current lift-aerodynamic blade systems. - wind tunnel testing confirms effectiveness of resonance tuning method. - potential for less use of materials if other operating parameters of this type of bladeless design can be further optimized.

𝐏𝐞𝐫𝐬𝐨𝐧𝐚𝐥 𝐢𝐧𝐬𝐢𝐠𝐡𝐭𝐬 𝐢𝐧𝐭𝐨 𝐭𝐡𝐞 𝐟𝐮𝐭𝐮𝐫𝐞 𝐨𝐟 𝐦𝐢𝐜𝐫𝐨 𝐚𝐧𝐝 𝐩𝐢𝐜𝐨 𝐡𝐲𝐝𝐫𝐨𝐞𝐥𝐞𝐜𝐭𝐫𝐢𝐜 𝐞𝐧𝐞𝐫𝐠𝐲 It is often mentioned that in some countries, or continents such as Europe, hydroelectric technology has now reached its maximum installed capacity, both due to the lack of new heads to be exploited, but also in the face of socio-political issues that do not facilitate the construction of new large plants. In the last decade/twenty years there has been a very competitive race in search of available heads, with a great scouting activity by large organizations but also by private individuals. In my opinion, the future of continuing to exploit hydroelectric technology is played out on two fronts: 🎯 repowering existing plants to restore or increase their efficiency; 🎯 concentration on mini, micro, pico hydroelectric. Regarding this last front, we hear more and more often about new technologies such as hydrokinetic turbines. ⚠️ Their operating principle is similar to wind turbines, with a maximum efficiency which, in compliance with the Betz limit, cannot exceed approximately 60%. 👉 In this regard, one might ask why not focus more on a type of technology that provides an efficiency level of up to 80% or even more, such as the wheels of old mills. Some time ago I came across a European-wide website with many places where you can find old mills (50,000 projects!). https://lnkd.in/d8hY2Z-C What do you think about this? 💡 Ultimately in my opinion the game is played on the field of the solution with the best efficiency. #Hydropower #Hydroelectric #Future #Efficiency
