ICOLD president says environmental responsibility is top priority
Months into a three-year term as president of the International Commission on Large Dams, Jia Jinsheng told Hydro Review Worldwide that the evolving field of dam engineering must place environmental issues at the top of its priorities.
ICOLD, founded in 1928, is a non-governmental organization that provides a forum for the exchange of information and expertise pertaining to dam engineering and related topics. Some of the organization’s goals are to ensure that dams are built safely and in an environmentally-friendly manner. The commission includes national committees from more than 80 countries.
“Looking to the future, we will have to be much more sensitive to environmental issues in order to be socially acceptable and environmentally friendly,” Jinsheng said in a recent interview. He noted that new ideas and practices regarding environmental issues are emerging in many aspects of the field.
Throughout the history of ICOLD, the organization’s aim has shifted to include emerging areas of concern such as planning, construction, operations and design.
Jinsheng emphasized that ICOLD was set up with one of life’s necessities, water, at the forefront. With that in mind, the organization strives for safety and for dams that are built and operated in environmentally-safe ways, he said.
National emergency plan prepared for Akosombo and Kpong dams
The Volta River Authority is preparing an Emergency Preparedness Plan to identify, prevent, and limit the effects of potential dam failures at Akosombo and Kpong.

IDB loan approved for 80-MW project in Bolivia
Bolivia will receive US$106 million in loans from the Inter-American Development Bank (IDB) to finance the construction of the 80-MW Misicuni hydroelectric project.
Construction of the dam on Bolivia’s Misicuni River began in June 2009.
In addition to generating electricity for Bolivia’s national grid, the project is expected to boost water supplies for domestic use and irrigation activities in the Cochabamba Valley.
“Through this project, Bolivia is showing that when water is sustainably managed, it can become a strategic resource that generates improved human health, increased food production, and greater access to clean, renewable energy,” said IDB President Luis Alberto Moreno.
The IDB loan will be used to build the hydroelectric component of the project, including transmission lines. The project is being financed by the government of Italy, the Prefecture of Cochabamba, Bolivia’s National Treasury, and the Andean Development Corp.
An additional US$5 million in IDB financing will be used to reduce erosion, enhance water management, and protect priority habitats in the areas of the watershed most exposed to such risks.
World Bank approves loan for Ukraine rehab project
The World Bank approved a US$60 million loan for the rehabilitation of three hydroelectric plants in Ukraine.
The loan will be used to finance improvements to several units at the Kremenchuk hydro plant and two Dniprovska hydro plants, the World Bank said.

British Hydropower Association offers mixed reaction to new tariffs
While the British Hydropower Association said it welcomes the Department of Energy and Climate Change’s final version of the Feed-in Tariff scheme for renewable power, it says some issues must be addressed.
The new plan shows stronger tariffs for hydro that are in line with extensive work carried out by the hydropower association for the consultation process.
“This helps to reassure those who finance new hydro projects, thus encouraging realization of hydro’s vast potential in the United Kingdom,” said David Williams, the association’s chief executive officer.
However, there are certain issues within the detail of the structure that will effect the fulfilment of the total potential development, the association said.
These are mainly related to schemes that have pre-registered for the old system within the Renewables Obligation. If this was done before April 2008, scheme owners can no longer apply for feed-in tariffs and cannot afford to complete the scheme under the Renewables Obligation.
“This effectively quarantines a number of projects trapped in this time limitation,” Williams said. “We must fight to get the structure modified.”
Another area of contention is the inability to use refurbished equipment for the feed-in tariff regime. One of the big advantages of hydropower is that, with refurbishment, hydro plants can last easily for 100 years. Under the Renwables Obligation, refurbishment was allowed. Now it is not, again limiting the most reliable source of renewable electricity generation, the association said.
World Bank: Africa needs more hydropower
A recent study from World Bank shows that almost half of the $93 billion needed to improve Africa’s infrastructure must be spent on the construction of new power supplies.
The study, Africa’s Infrastructure: A Time for Transformation, assessed the infrastructure in 24 countries across the continent and found that Africa’s largest infrastructure needs are in the power sector and that the development of new hydropower may be the best way to increase the continent’s capacity.
“The most cost-effective way to expand Africa’s power generation is through regional trade,” the study found. “Mobilizing the benefits of regional trade depends on developing major untapped hydropower projects in the Democratic Republic of Congo, Ethiopia, and Guinea.”
Such a plan would require 22,000 MW of interconnectors to deliver power freely from country to country, the study states. The ability to trade power supplies “would increase hydropower’s share of the continent’s generation portfolio from 36 percent to 48 percent,” the study found.
Preliminary license issued for Belo Monte project
Brazil’s environmental authority, Ibama, issued a preliminary license for the 11,200-MW Belo Monte hydro project in the Amazon region, subject to a number of conditions covering environmental concerns and other issues.
The preliminary license allows the auction for construction of the project to proceed. Belo Monte will cost at least 16 billion reais (US$9.3 billion), according to the Brazilian Association of Infrastructure and Basic Industries.
The project, on the Xingu River in the state of Para, is Brazil’s second-largest hydro project after the 14,000-MW Itaipu complex in southern Brazil. The auction for Brazil’s Belo Monte hydro plant is scheduled for April 2010, a spokesperson for Brazil’s mines and energy ministry told Business News Americas.According to Ibama, Belo Monte constructors will have to pledge 1.5 billion reais (US$793 million) for preservation works to compensate for the environmental impacts of the project.
French utility again seeks suppliers of 50 hydro turbine-generators
Electricite de France (EDF) renewed its qualification system for companies to supply about 50 turbine-generators and other equipment over five years to hydro projects in the EDF system.
EDF said it intends to install hydro generating units of 100 kW to 12 MW over five years and seeks to qualify a panel of equipment suppliers for the period in which it would issue invitations to tender. The utility said the qualification notice is a renewal of a similar notice in 2008.
In a separate solicitation, the French utility invited hydro equipment suppliers in February 2009 to qualify to provide turbines to projects in the utility’s hydroelectric system.
In the current solicitation, companies would be required to supply and commission turbine-generator sets of less than 12 MW, possibly including civil engineering, valves, pressure pipe, and electrical and control equipment.
European countries plan grid to link hydro, other renewables
Nine European countries are backing a plan to develop a US$43 billion North Sea renewable energy transmission network that would link tidal power projects, offshore wind farms, hydroelectric plants and other renewable energy sources.
Germany’s minister for economy and technology said the project linking the countries to renewable energy was “crucial” to Europe’s energy goals.
Rainer Bruderle, Germany’s minister for economy and technology, said the offshore energy park that would link tidal power with wind and hydroelectric plants “focuses on network connections and integration, which is crucial for wind energy to reach consumers and to make offshore energy generation a success.”
The plan calls for new cables that could handle the fluctuations inherent in renewable energy sources.
They would connect offshore windmills controlled by Germany and Britain with hydroelectric sources in Norway and tidal power stations controlled by Belgium and the Netherlands.
Zambia plans construction of 600-MW Kafue Gorge project
Zambia plans to begin construction of a $1.5 billion hydro project in 2011, with the project’s completion planned for 2017.
Officials say the government will engage the private sector to help build the 600-MW Kafue Gorge Lower hydroelectric project in a two-stage tender process. The Zambian Government will put up $250 million, with a comparable sum coming from private equity.
The project could meet as much as a quarter of the country’s electricity needs.
