Austria utility to expand 9.58 MW Opponitz
Vienna utility Wien Energie GmbH is moving forward on an expansion of its 9.58 MW Opponitz hydroelectric project on Austria's Ybbs River.
Wien Energie plans €30 million (US$38.1 million in economic and environmental improvements to the 88 year-old hydroelectric project. Work is to include a fish ladder and a new weir at Gostling that will increase the amount of water available to be used by the Opponitz hydro plant. An additional turbine-generator is to be added to the project, with installed capacity to increase to 12.5 MW.
The utility has been seeking a company to supply, install and commission hydraulic steel structures, earthworks and construction for the expansion, as well as to supply, install, and commission a residual water turbine-generator unit at the Gostling weir.
Modernizations under way at France's 5 MW Pont Baldy plant
Energie Developpement Services du Brianconnais (EDSB) is modernizing its 5 MW Pont Baldy hydroelectric plant in Briancon, France.
Alstom is working on the rehabilitation, replacing the automatic voltage regulator with a digital control system known as "SMARTGEN." This regulator can produce electricity at constant voltage, allowing the Pont Baldy facility to remain operational and free of downtime caused by voltage fluctuations.
Alstom said the system is "perfectly suited to the specific requirements of owners of small hydro power stations" and that when paired with maintenance diagnostic software, it can "help operators to independently intervene and retain control of equipment maintenance."
Pont Baldy was commissioned in 1966 with a 5 MW horizontal Francis turbine supplied by Alstom that produces 18 GWh of electricity annually.
Alstom installed a new speed regulator at Pont Baldy in 2006 but said the installation of the SMARTGEN system is the first step in a new modernization project.
EDSB also operates the Roche Percee and Le Randon hydropower plants, which supply power to more than 11,000 consumers in Briancon and Saint Martin de Queyrieres.
Officials investigate incidents at two Vietnamese small hydro plants
Officials are working to determine what caused a dam to collapse at the 8 MW Dak Rong 3 hydroelectric plant in Vietnam and are also investigating the dam that impounds water for the 7.5 MW Dak Mek plant after the structure sustained significant damage.
The 25 meter-long by 6 meter-high Dak Rong Dam, recently completed by Truong Son Hydropower JSC, suffered a 20 meter-long breach in mid-October 2012 that caused more than US$1 million in damage to the structure and surrounding fields.
Truong Son said the failure was caused while it was experimenting with water storage and that torrential rains caused by Typhoon Gaemi overwhelmed the dam.
|A dump truck caused considerable damage when it crashed into Dak Mek Dam in Vietnam, causing portions to collapse and release water downstream.|
However, officials from local governing group Quang Tri Province People's Committee Secretariat say evidence of substandard construction work has been found in the debris. Much of the remaining work includes weak concrete that can be dislodged by hand, substandard rebar, and construction techniques that could have led to the dam's collapse, they say.
The group also says Truong Son Dam was storing water without making it known to the public, potentially endangering life and property in the areas downstream.
Mai Van Hue, chairman of Truong Son's board of directors, said the company is repairing the damaged portion of the dam but repairs could take several months because it is Vietnam's rainy season.
At Dak Mek 3, Vietnamese sources report a 60 ton dump truck hit the 60 meter-long, 20 meter-tall cement dam in late November, killing the driver and causing large portions of the dam to collapse into Dak Mek Stream.
The Hong Phat Dak Mek Hydropower Joint Stock Company, which owns the project, said the dam was being built "in accordance with quality standards and the approved design."
Officials with Vietnam's Dak Lak Province have begun an investigation, however, noting that the damage seemed too significant not to have been caused in some part by construction or design flaws.
Reports of the cause of the breach vary. According to one source, an inspection team reported that the project owner and investor, Hong Phat Dak Mek, did not follow design plans and used sand, earth, and stone instead of concrete. The project owner reportedly violated a governmental regulation when it failed to report the breach within 24 hours.
As a result, the province's People's Committee requested that construction be suspended and that the investor provide updated design and construction documentation to the Department of Construction. Hong Phat Dak Mek was also made responsible for investigating mitigation measures to deal with the aftermath of the breach in Dak Mek stream.
Work on the US$10 million project had been ongoing since March 2009 and was about 80% complete.
Delayed Windsor Castle hydro project hits another snag
Testing of new hydroelectric equipment at England's Windsor Castle has once again been delayed by high water levels in the River Thames.
Work on the US$2.7 million scheme slowed in August 2012 due to complications associated with the project's 11 kV transmission line.
The project is being developed by Southeast Power Engineering Limited and includes two Archimedes Screw turbines. Energy produced by the identical 12-meter by 4-meter units will be used to power Windsor Castle, with surplus electricity fed into England's national grid.
Officials say testing of the project will begin as soon as water levels drop, with the turbines being operational in three months.
IIC approves loan for small hydro plant on Peru's Pachacayo River
The Inter-American Investment Corporation (IIC) approved a loan of US$7.2 million to Empresa de Generacion Electrica Canchayllo S.A.C (EGECSAC) to develop, build, and operate a 5.26 MW hydropower plant on the Pachacayo River in Peru.
The US$11 million hydroelectric project will operate under a concession agreement with the Peruvian government that will allow EGECSAC to sell the energy generated at a fixed price for 20 years.
"We are very grateful to have received IIC financing for this first renewable energy project," said Jose Garcia Herz, general manager of EGECSAC's majority shareholder, Cascade Hydro Power. "We have three projects of this type scheduled to begin construction in late 2013. With them, we hope to become Peru's leading renewable energy company."
IIC said energy demands in the South American country could increase by as much as 65% over the next six years. That increase equates to an additional 3,300 to 5,300 MW of power by 2018, according to IIC.
Lender plans feasibility study of Rwanda's 3 MW Nyundo
