  Last year's drought in China's Yunnan province slashed hydro power generation by nearly 30 per cent during the first five months of 2020, according to official data. Output this year remains curtailed by around 10 per cent. Yunnan usually accounts for roughly a quarter of China's total hydro generation, and the province is home to several aluminum smelting businesses that require vast quantities of power to operate. The province restricted metal producers' power use earlier this year, forcing some smelting capacity to be temporarily shut. More disruptions are expected. A recent study by researchers in Nanjing looked at the potential impact of climate change and rising temperatures on hydropower generation in Yunnan. Their models showed decreases in rain and snowfall during the October-April drought season and increases in the summer rainy season. To even out the variability, the researchers proposed more storage capacity - more dams and reservoirs. But the diversions ...

  Khyber Pakhtunkhwa’s four 244.4 MW renewable and cheap electricity hydropower projects are stalled due to negligence of the Ministry of Energy (Power Division) and PESCO for the last three years. The projects are pending due to non-approval, notification, import certificates, and purchase agreement. Similarly, Pakhtunkhwa Energy and Development Organisation (PEDO) has an arrear of Rs7,147.604 million in electricity sales to the federal government. A reliable government source told this correspondent that the projects were delayed due to bureaucratic hurdles, which are hampering the production of cheap electricity, while Prime Minister Imran Khan is focusing on cheap hydropower generation in the country. Ongoing hydropower projects are also being affected due to non-payment of dues. According to documents available with this correspondent, the PEDO for the first time in Pakistan for hydropower projects conducted internationally competitive bidding in February 2016 for six projects...

  The central province of Quang Nam has scrapped plans for building four hydropower plants, the province People's Committee said. Nguyen Hong Quang, its deputy chairman, said Monday the People's Council decided to remove four small and medium-sized projects -- A Vuong 4 in Tay Giang and Dong Giang districts, Song Bung 3 in Nam Giang District, A Banh in Tay Giang District, and Dak Di 4 in Nam Tra My District – from the list of planned hydropower plants as they have low capacity, severely impact the environment, require large tracts of land, and bring low economic benefit. The fact their investment procedures were tardily completed impacted the planning and construction of other infrastructure and caused disapproval in the community, he said. "The scrapping of these hydropower projects is also to re-evaluate the impacts of small and medium-sized hydropower plants." Two other plants in Nam Giang District, Cha Val and Dak Pring 2, are also being considered for removal, ac...

  THE HAMMER EFFECT (OR WATER HAMMER) CAN HARM VALVES, PIPES, AND GAUGES IN ANY WATER, OIL, OR GAS APPLICATION . IT OCCURS WHEN THE LIQUID PRESSURE IS TURNED FROM AN ON POSITION TO AN OFF POSITION ABRUPTLY. WHEN WATER OR A LIQUID IS FLOWING AT FULL CAPACITY THERE IS A NORMAL, EVEN SOUND OF THE FLOW. YOU CAN TELL WHEN WATER HAMMER OCCURS BECAUSE THERE WILL TYPICALLY BE A BIG THUMP SOUND OR A SERIES OF THUDDING NOISES. THAT NOISE IS THE IMPACT OF THE ENTIRE TRAIN OF WATER COMING TO A QUICK HALT CREATING A SHOCK WAVE. IN THE CASE OF PRESSURE GAUGES, THIS SHOCK CAUSES A SPIKE THAT CAN DAMAGE THE GAUGE EVEN IF THE GAUGE IS THE CORRECT PRESSURE RANGE FOR THE PARTICULAR FLOW APPLICATION. ORDINARILY PRESSURE SYSTEMS SHOULD HAVE AIR CHAMBERS (OR CUSHIONS) INSTALLED THAT SOFTEN THE IMPACT AND PREVENT THE HAMMER EFFECT. ESSENTIALLY, AN AIR CHAMBER IS A VERTICAL SECTION OF PIPING WITH A CAP ON THE END THAT IS ATTACHED TO THE SUPPLY LINE NEAR THE SHUTOFF VALVE. IT IS FILLED WITH ...

  ueensland’s largest hydropower station, the 570MW Wivenhoe Pumped Storage Hydroelectric Power Station, will undergo a $14 million overhaul to ensure it continues to produce cleaner, cheaper energy for years to come. Major maintenance works will start at the Wivenhoe station this month, creating 100 jobs under the Palaszczuk Government’s COVID-19 Economic Recovery Plan. The plant is owned by CleanCo Queensland. Minister for Energy, Renewables and Hydrogen Mick de Brenni said Wivenhoe was incredibly valuable to the reliability of Queensland’s electricity network. “All our publicly-owned energy generators have worked around the clock to respond to constraints in the network in these last few weeks,” de Brenni said. “When Callide C Power Station went offline in May, we were able to ramp Wivenhoe up to the point it was generating 530 megawatts over a four-hour period, helping to meet demand and stabilize the network. Never has it been more important to invest in fast ramping...
