YICHANG, Hubei, Nov. 20 (Xinhua) -- China has established the world's
largest seismological network for monitoring and preventing earthquakes
near major reservoirs, a senior scientist said Sunday.

The network is located in the lower reaches of the Jinsha River, which
constitutes part of the upper reaches of the Yangtze River, China's
longest waterway, Chen Houqun, a member of the Chinese Academy of
Engineering, said at a hydropower development forum held in central
China's Hubei province.

Several dams with a height of over 300 meters have been built in west
China in recent years, a region that has also experienced 82 percent of
the country's strongest earthquakes, according to Chen.

Authorities should be wary of earthquakes that occur near major
reservoirs, despite the fact that strong jolts are rarely reported in
those areas, Chen said.

In response to concerns that the large dams might actually cause
earthquakes, Chen said there is no reason to panic.

"There are hundreds of thousands of reservoirs in the world, but only
about 100 reservoir-triggered quakes have been reported," he said.

Kariba extension: Zesa drops Sino Hydro deal

Zesa drops Sino Hydro deal
Zimbabwe Independent
Thursday, 17 November 2011

By Paidamoyo Muzulu

ZESA has renounced the Memorandum of Understanding (MoU) clandestinely
signed between treasury and Chinese conglomerate Sino Hydro for the
expansion of the Kariba South hydroelectric power project opting for a
more transparent tender process. Kariba presently generates 750
megawatts of power at its peak and the MoU seeks to increase generation
capacity by an extra 600 MW. It was signed by Finance minister Tendai
Biti and Economic Planning and Development minister Tapiwa Mashakada
early this year.

Investment in the country has been subdued in the last decade with Zesa
failing to provide uninterrupted power supply to the manufacturing
industry. The power authority sometimes switches off consumers for up to
12 hours as part of its haphazard load-shedding schedule.

Zesa chief executive officer Josh Chifamba told the Mines and Energy
Portfolio Committee on Monday that the agreement awarding Sino Hydro the
Kariba expansion work had jumped the gun and would cause problems with
other Chinese companies should it be implemented without going to tender.

"Sino Hydro made an offer, (but) it jumped the gun on many issues," said
Chifamba. "The feasibility studies had not been done. We were going to
have problems with other Chinese partners. The only way was to go to
international tender," he said.

Chifamba said such large projects needed very high levels of
transparency to encourage investment and participation by the most
competent company through a tender process.

"We need maximum transparency to encourage funding. This would also give
us an opportunity to evaluate the best tender and compare the services
of the companies in an open manner," Chifamba said.

The debt laden energy utility conceded that the perennial power
shortages could only be solved by engaging in Public Private
Partnerships (PPP) to build new electricity generation plants. However,
Chifamba suggested that investors were wary of Zimbabwe�s inconsistent
policies.

"We are not the most attractive investment destination in the world," he
said. "Electricity generation is a long term investment. There must be
stability, and currently there is nervousness among investors, for
instance, around indigenisation policy."

Most local parastatals are debt ridden making them unattractive to
investors. Zicosteel owes about US$240 million to Chinese and German
banks. The situation is the same at the National Railways of Zimbabwe,
Air Zimbabwe, Noczim, Grain Marketing Board, Agribank, Cold Storage
Company, TelOne, NetOne and the Zimbabwe Power Company (ZPC). The ZPC
has been shortlisted for privatisation or restructuring in the short to
medium-term.

In another development, Chifamba announced that Zesa would soon embark
on the ambitious Batoka hydro-power project with potential to generate
3000MW after finally agreeing to settle a US$260 million debt to Zambia
for the shared Kariba infrastructure inherited at independence in 1980.

The dispute revolved around an unpaid debt for infrastructure that
Zimbabwe inherited at Independence from the Central African Power
Corporation (Capco) during the federation era.

Chifamba said: "Zesa will start servicing the Capco debt commencing next
January and that will give us the greenlight to start the Batoka project."

Zimbabwe's power stations are operating at 50% capacity and producing 1
300 MW compared to a national demand of 2 400 MW. The utility meets the
shortfall by importing from the DRC's power company Snel, Eskom of South
Africa and HCB of Mozambique.

Nature reserve determined for major riverheads ecology

Nature reserve determined for major riverheads ecology
Xinhua News

http://news.xinhuanet.com/english2010/china/2011-11/17/c_131251322.htm

BEIJING, Nov. 16 (Xinhua) -- The Chinese cabinet determined Wednesday a
national nature reserve for headwaters of three major rivers in China,
setting a target of vegetation coverage growth at 30 percent in a decade.

A State Council executive meeting, which was presided over by Premier
Wen Jiabao, made the decision. The nature reserve will cover Qinghai's
21 counties of four Tibetan autonomous prefectures and one town of
Golmud, through which the Qinghai-Tibet Railway passes.

The headwaters of the Yangtze, Yellow and Lancang rivers in the
northwest province are important sources of fresh water for the whole
country and essential to ecology on the Qinghai-Tibet Plateau.

The Lancang River, the upper stream of the Mekong River, runs southward
to irrigate a few Southeast Asian countries.

The Chinese government started to implement an overall program for the
area's ecological preservation in 2005.

The government hopes the average vegetation coverage increase in the
nature reserve of 15 to 20 percent more in 2015, and of 25 to 30 percent
more in 2020.

The government also encourages individuals, non-government organizations
and social groups to support and get involved in environmental and
ecological protection in the area.

World’s Biggest Hydropower Scheme Will Leave Africans in the Dark

http://ipsnews.net/news.asp?idnews=105843

World�s Biggest Hydropower Scheme Will Leave Africans in the Dark

By Kristin Palitza


CAPE TOWN , Nov 15, 2011 (IPS) - South Africa and the Democratic
Republic of Congo have signed an agreement to build a major
hydroelectric power project, which is said to bring electricity to
more than half of the continent�s 900 million people. But economic
analysts warn that foreign investors will prevent the grid from
benefiting the general public.

Together with his Congolese counterpart President Joseph Kabila, South
African President Jacob Zuma witnessed on Nov. 12 the signing of a
deal to construct the Grand Inga Dam. Grand Inga will be built 225
kilometres southwest of the DRC capital Kinshasa, on one of the
largest waterfalls in the world, the Inga Falls, where the Congo River
drops almost a hundred metres and flows at an enormous speed of 43
cubic metres per second.

The Grand Inga hydropower project will have a capacity of 40,000
megawatts (MW) � more than twice the power generated by the Three
Gorges Dam in China, the world�s largest hydropower dam, and more than
a third of the total electricity currently produced in Africa.

"It will enhance energy access to clean and efficient energy across
the continent and contribute significantly towards a low carbon
economy and economic development," declared Zuma in the DRC�s second-
largest city Lubumbashi, where the signing took place. Zuma described
the event as "a day to prove Afro-optimists right."

Grand Inga will be the world�s largest hydropower scheme and part of a
greater vision to develop a power grid across Africa that will spur
the continent's industrial economic development. Up until now, the
power of the Inga Falls has been largely unused, with the two existing
hydroelectric dams, Inga I and Inga II, operating at a low output of
mere a 1,775 MW.

The reasons for the underutilisation of the waterfall�s power has
largely been money: The construction of Grand Inga � with completion
pegged at 2025 � comes with a whopping price tag of 80 billion
dollars. Connecting Inga to a continent-wide electricity grid will
cost at least an additional 10 billion dollars. These are not sums
South Africa and the DRC are able to bankroll alone.

But help is not far: The globe�s top development financiers, World
Bank, African Development Bank (AfDB), European Investment Bank as
well as a number of private, foreign energy companies are all keen to
contribute large sums to the Inga project. In return, they expect to
gain vast economic benefits from this mega-project � and are likely to
take away attention from the development needs of Africa�s poor
majority.

"Foreign investors are contributing to the construction of the dam to
get their share of large quantities of cheap power upon completion of
the project," warned Institute for Democracy in Africa researcher
Charlotte Johnson, who is based in South Africa. "This will force the
state�s hand � to enter into agreements concerning the final
destination and usage of the power generated."

Despite the development-focused marketing hype surrounding the
project, the Congolese government and investors have made no plans to
open the grid for public use, said Johnson. Instead, it is marketed as
a commercial product. And foreign investors will always be able to pay
more, instantly removing the poor from the consumer competition.

"Local power grids are not included in the budget. African communities
living in darkness are not the intended beneficiaries of Grand Inga,
and the 500 million people who have been promised electricity will
remain in the dark," she added.

For now, the project looks at building only long-distance transmission
lines to Africa�s mining and industrial heartlands as well as to urban
centres in South Africa, Egypt and even Europe.

According to the AfDB, a Franco-Canadian consortium is in the process
of conducting a 15 million dollar study to assess the potential for
developing the site in stages.

"This is a major investment, and it won�t be possible to mobilise
resources in one go. The final decision will of course be taken by the
DRC government," explained AfDB director of energy, environment and
climate change Hela Cheikhrouhou at the development bank�s annual
meeting in October.

According to the AfDB, hydropower represents 45 percent of power
generation potential in Sub-Saharan Africa, but only four percent has
currently been tapped. As a result, only every fifth person has access
to electricity in the region.

"To achieve energy access for all, Africa must maximise clean energy
options, emphasise energy efficiency and work with developed countries
and development institutions to quickly and effectively channel a more
substantial share of climate financing," she added.

With the backing of the world�s major development banks, the DRC and
South Africa are forging ahead with their plans to build Grand Inga.
After the signing of the agreement, Zuma and Kabila ordered the start
of negotiations for a treaty over the next six months, which will put
into effect the agreement by detailing time frames and implementation
stages for the dam construction.

Once completed, the generated electricity will be managed by the state-
owned utility companies of both countries, South Africa's Eskom and
the DRC's Societe Nationale d'Electricite Societe a Responsibilite
Limitee National. From there it will be sold to the highest bidders.
Africa�s still unconnected poor will certainly not be among those. (END)

Public consultation underway on Nam Ou dam, Laos

Public consultation underway on Nam Ou dam

Vientiane Times
By Khamphone Syvongxay
November 14, 2011

Construction of the Nam Ou 2 dam in Luang Prabang province could begin
next year following reviews of the environmental and social impact
assessments.

A national consultation workshop on the environmental and social impact
assessments of the dam was held in Vientiane last week, attended by
government representatives, provincial authorities and members of the
public whose lives are likely to be impacted by the project.

The dam is planned at a location 53km from the mouth of the Nam Ou
river, spanning the two districts of Ngoy and Nambak and measuring 49m
in height and 300m in length.

The proposed plant would have a capacity of 120MW and would be able to
produce 546 KWh of electricity per year. The site will span 16 square km
with construction costs estimated at US$15.6 million, according to a
government report.

The project is expected to benefit people in the northern provinces by
supplying electricity to households and for further development.

The government has agreed to sign a memorandum of understanding (MOU)
with Sinohydro Corporation to study the possibility of seven dams on the
Nam Ou river. The project has commissioned Earth Systems Lao to carry
out a feasibility study and make environmental and social impact
assessments.

At present, Sinohydro Corporation plans to build only three dams, the
Nam Ou 2 in Luang Prabang province and the Nam Ou 5 and 6 in Phongsaly
province, Deputy Minister of Natural Resources and Environment Mr
Sisavath Vithaxay told the workshop.

The government has signed an MOU to supply 7,000MW of electricity to
Thailand after 2015 and 5,000MW to Vietnam by 2020, he said.

To reach these targets, Laos needs 30 small, medium and large hydropower
plants, he added.

The government has also signed an agreement to sell 20MW of electricity
to Stung Treng province in Cambodia.

The government has promised it will use the income earned from the sale
of electricity to develop the economy and alleviate poverty.

The first benefits for Lao people will be improvements in health,
education, social services, transport, and water and electricity supply.

"As we are aware, the energy sector, particularly hydropower, has
contributed to socio-economic deve-lopment and through this workshop I
hope we can overcome any environmental and social problems so that the
project can go ahead and run smoothly," Mr Sisavath said.

Kenyan firm plans 61 MW wind power farm

http://af.reuters.com/article/investingNews/idAFJOE7AD03120111114

Kenyan firm plans 61 MW wind power farm
Mon Nov 14, 2011 6:34am GMT


NAIROBI (Reuters) - Kenyan firm Kinangop Wind Park Ltd plans to
generate 60.8 megawatts (MW) of electricity for the national grid by
harnessing renewable wind power, it said on Monday.
The east African nation relies heavily on hydroelectric dams for
power, which have proved inefficient in times of drought.

Recent back-to-back incidences of low rainfall have slashed the
country's hydropower production, leaving consumers with high
electricity bills after producers turned to more expensive thermal
power.

"The project consists of building a 60.8MW wind power park in Kinangop
in order to supply additional power to the national grid," it said in
a statement.

The firm said it will apply for a power generation licence from the
sector regulator on December 5.

Investors in the east Africa's largest economy are turning more to
renewable sources such as wind and geothermal to help stabilise
supplies of electricity.

Kenya has several wind power projects lined up for implementation
including one for 300MW planned for the north of the country.

Lake Turkana Wind Power (LTWP) -- a subsidiary of Dutch wind power
firm KP&P -- behind the 617 million euro project, said in March
construction would start by December.

Kenya's main power producer Kenya Electricity Generating Company is
already generating over 5 MW from wind in the outskirts of the capital.

Another firm, Aeolus Kenya, is in the process of implementing a 60MW
wind power project to be located in Kinangop Plateau in central Kenya.

Kenya has set a target of 30,000 megawatt (MW) generation by 2030, the
year in which it hopes to become a middle-income country. At present
it has a capacity of 1,400 MW and is slated to install another
2,000-3,000MW within the next five years.

Climate change 'threatens Nile, Limpopo rivers'



Climate change 'threatens Nile, Limpopo rivers'

JOHANNESBURG — Rising global temperatures and shifting rainfall patterns could affect water flows on Africa's mighty Nile and Limpopo rivers, an agricultural research group said Monday.

The Consultative Group on International Agricultural Research, a global think-tank, warned the changes could have major effects for countries that share the rivers -- raising the risk of conflicts erupting over water use, already a subject of often touchy regional relations.

Their study raised the greatest concerns for the Limpopo River Basin, including parts of Botswana, South Africa, Mozambique and Zimbabwe, and running through a region already chronically dry.

The findings were presented at the International Forum on Water and Food in Pretoria.

The group's projections found that between now and 2050 hotter weather and fewer rains could hurt food production and deepen poverty.

"We need to ask whether current agriculture development strategies in the Limpopo, which are predicated on current levels of water availability, are in fact realistic for a climate future that may present new challenges and different opportunities," said Simon Cook, a scientist who worked on the project.

"In some parts of the Limpopo, even widespread adoption of innovations like drip irrigation may not be enough to overcome the negative effects of climate change on water availability," Cook added.

For the Nile, the researchers projected that increased water evaporation could "reduce the water balance of the upper Blue Nile Basin."

That could affect regional talks on management of the river, after years of tensions over Ethiopia's plans for new dams, the researchers said.

"The new insights regarding the effect of climate change on river basins may indicate a need to revisit assumptions about water availability," said Alain Vidal, director of the group's water and food programme.

In rivers around the world, the study found that higher global temperatures would make more water evaporate from rivers, which in most cases should be set off by increased rainfall.

But within river basins, changes could prove dramatic, and flip weather trends from wet to dry for regions that previously have known consistent patterns, it found.

"Such changes will create a management nightmare and require a much greater focus on adaptive approaches and long-term climate projections than historically have been necessary," said Vidal.
