Yes, this is a picture of a dump truck being hoisted up a
mountain on cables. And no, it’s not photoshopped. You’re
looking at the largest cable lift in the world, almost 2
kilometers long and 600 meters high, with two towers, a load
capacity of up to 40 tons, cables 90 mm thick, and a pretty good
speed of 5 meters per second.
The system took three years to build. And transport dumpers are
not the heaviest loads it can carry :o, although they’re
probably the most photogenic. ;D The system can also lift whole
ship containers.

Next surprise: this mammoth cable system is only a temporary
fixture. It’s there to support construction of a huge $1.5
billion hydroelectric pumped-storage power plant called Linthal
2015.
Workers from the Linth-Limmern AG utility, its partners the
Canton of Glarus and Axpo AG, are now building this electric
Godzilla about an hour from Zurich, Switzerland, high in the
rocky Glarner mountains of the eastern Alps. As you can see from
the photo, the area is so mountainous that road access for
construction is impossible—thus the cableways.

Peak energy demand in the European grid is growing steadily.
Consumption patterns and forms of production have changed
considerably since construction of the original infrastructure.
Production peaks/shortfalls from renewable power sources may
require balancing at short notice. Also, security of supply has
become a higher priority. These considerations all increase the
usefulness of electric generators with peak-power storage. As
well as providing power, Linthal 2015 will basically act as a
huge battery.
HTML http://www.pic4ever.com/images/19.gifhttp://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg<br
/>
Workers expect to complete the plant next year. (Their
grandparents had a little practice with this type of project,
having built an artificial lake [the Limmernsee] and an earlier
480 MW power plant lower down the mountain, at 1,900m above sea
level, in the 1960s.) The new storage lake (Muttsee) will be 600
meters higher up the mountain than the Limmernsee. The lakes
will be connected via two headrace tunnels and produce a net
hydraulic head of 623 meters (2,044 ft).
HTML http://i2.wp.com/cleantechnica.com/files/2014/05/Mountain-cross-section.png
HTML http://www.pic4ever.com/images/8.gif
A huge, deep cave with an inclined underground access gallery
will house all the turbine and transformer machinery. Planned
pump and turbine power is about 1,000 MW. With the output from
the original facility, the Linthal 2015 project will produce
easily as much power as a nuclear generating
station.
HTML http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif<br
/>It will rank among the top 15 pumped-storage plants in the
world.
HTML http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-013.gif
The cablecar system will be dismantled when a funicular railway
inside the gallery is complete. The railway will transport
large, heavy machine components—including 215-ton
transformers—and personnel directly from the base installation
site of Tierfehd, near the foot of the mountain, to the turbine
cavern. 380 kV cables run along the gallery shoulders will
transmit the generated power.
Now, would you like to hear about the avalanche protection
system?

Hydro-Quebec celebrates 70th anniversary
Canadian provincial utility Hydro-Quebec celebrated its 70th
anniversary in mid-April, noting that hydroelectric power was
and continues to be part of the company's success.
Founded April 14, 1944, with the passage of an act establishing
the Quebec Hydro-Electric Commission, Hydro-Quebec wasted little
time breaking ground on its 1,178-MW Bersimis 1 and 869-MW
Bersimis 2 hydro plants.
The boom in energy demand post-World War II quickly necessitated
the construction of additional projects, with hydro plants on
the Manicouagan River and Riviere Aux Outardes being built in
the late 1950s.
Hydro-Quebec faced a pivotal moment in fall 1962 when the
provincial government, headed by Jean Lesage, proposed the
nationalization of all power utilities under the election slogan
"Maitres Chez Nous," or "Masters in Our Own House." The movement
led Hydro-Quebec to purchase 10 privately-held electric
companies in May 1963 under the direction of Rene Levesque.
Since then, the utility has faced a number of challenges,
including standardizing rates throughout the province,
electrifying rural areas and setting up an effective
distribution grid.
The company now operates 61 hydro projects that have a
cumulative capacity of more than 36,000 MW, ;D manages 34,000
km of transmission lines, employees 20,000 people, supplies 4.1
million customers and controls assets worth US$66.6 million.
Changes to Upper Lillooet hydropower project
Canadian power producer Innergex Renewable Energy Inc. has
reached agreements with provincial utility BC Hydro regarding
components of the Upper Lillooet hydropower project.
The Upper Lillooet project - which would have included the 74-MW
Upper Lillooet, 23-MW Boulder Creek and 16-MW North Creek
hydropower stations - will be located on Crown land in British
Columbia.
The project was granted environmental assessment certificates
from the British Columbia government this past January.
The new agreement increases Upper Lillooet's capacity to 81.4 MW
and Boulder Creek's to 25.3 MW. Meanwhile, the North Creek
hydroelectric plant has been cancelled.
The project is being developed by Creek Power Inc., which is a
joint venture between Innergex and the Ledcor Power Group Ltd.
Partnership announced for Jimmie Creek project
Alterra Power Corp. and Fiera Axium Infrastructure Inc. have
announced a partnership agreement for the ownership and
construction of the 62-MW Jimmie Creek hydroelectric plant.
Under the deal, Alterra will own 51% of the project, while Fiera
will own the remainder through a managed fund.
Alterra assumed 100% ownership of the project in November 2013
from General Electric, after signing development agreements with
the Klahoose First Nation for its construction in May 2012.
Construction is under way, with an expected completion date in
August 2016.
"We are delighted to add another hydropower project to our
diversified fund portfolio," Fiera executive Dominic Chalifoux
said.
All power generated by Jimmie Creek will be sold to BC Hydro
under a 40-year contract. Financial closing for the deal was
expected later this quarter.
Canadian developer eyes pumped-storage projects
HTML http://www.clker.com/cliparts/c/8/f/8/11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png<br
/>
Canadian company Turning Point Generation has announced its plan
to develop a pumped-storage hydropower project in Alberta with a
capacity of 80 to 150 MW.
The unnamed plant is TPG's first pumped-storage project,
although one necessary, the company said, for the province's
energy security.
TPG has identified several of what it calls "favorable" sites
and will now move ahead on the project's development.
"This project is our most advanced, has exceptional inherent
site characteristics and enjoys favorable reception from key
stakeholders, including the First Nations involved," TPG
official Peter Bubik said. "We believe the Alberta power market
provides an economical basis for pumped-storage at this time and
the market indications are showing increasingly favorable
economics for pumped-storage in the future."
Briefly...
BC Hydro plans to conduct dam safety reviews at three dams:
22-MW La Joie Dam, 42-MW Seton Dam and Terzaghi Dam, which
impounds water for two Bridge River generating stations.

Asian bank funds 290-MW Nam Ngiep 1 hydro project in Laos ;D
VIENTIANE, Laos
08/29/2014
The Asian Development Bank (ADB) has agreed to provide
assistance totaling US$217 million to support construction of
the 290-MW Nam Ngiep 1 hydroelectric project on the Nam Ngiep
River in Laos.
Japanese construction company Obayashi last year won a contract
to provide civil engineering works for Nam Ngiep 1 in Xaysomboun
and Bolikhamxay provinces. The project is being developed by Nam
Ngiep 1 Power Co. Ltd., which is jointly owned by Kansai
Electric Power of Japan, Electricity Generating Authority of
Thailand and Lao Holding State Enterprise.
ADB is supporting Nam Ngiep 1 under a public-private partnership
arrangement. The bank is providing an assistance package
consisting of a US$50 million direct loan, a 3.04 billion baht
(US$95 million) loan, and a B loan of US$72 million funded by
the Bank of Tokyo-Mitsubishi UFJ Ltd., Sumitomo Mitsui Banking
Corp. and Mizuho Bank Ltd., with ADB acting as lender of record.
The project also will be financed by Japan Bank for
International Cooperation and four Thai banks.
The project is to include a main power station, a reservoir of
67 square kilometers, a re-regulation power station and a
125-kilometer transmission line to connect to the Nabong
substation near Vientiane.
Upon completion in 2019, the project is to supply the bulk of
its power to Thailand with part of its generation to be used
domestically to raise Laos' household electrification rate.
World Bank supports Laos' hydropower, mining sectors
The government of Laos also signed an agreement in which the
World Bank is to continue technical assistance under a program
to build the capacity of Laos' hydropower and mining sectors.
The World Bank approved US$17.8 million in additional financing
to the hydropower and mining sectors project.
With financing from the World Bank's International Development
Association, Laos' Institute of Renewable Energy Promotion last
year took bids to become investor-operator of two
micro-hydropower projects in Laos' Houaphan Province. The World
Bank's International Finance Corp. also recruited consultants to
serve as stakeholder engagement/communications specialist for
the hydropower and forestry sectors in Laos.

Damn Dams: A choking hazard for Amazonia
A new report by WHRC scientists Marcia Macedo and Leandro
Castello highlights hydroelectric dam projects in the Amazon as
a key threat. The report, commissioned by the Living Amazon
Initiative of the World Wildlife Fund, entitled, “State of the
Amazon: Freshwater Connectivity and Ecosystem Health” reviews
the current state of watershed ecosystem health and identifies
key threats and opportunities for conservation across Amazonia.
The report finds that planned hydroelectric dam projects will
constrict every subwatershed and undermine the health of the
entire Amazonian watershed.
The health of the Amazon watershed depends on annual flood
cycles, which cause rivers to swell by as much as 20 meters each
year. As river water overflows into the floodplains, rivers
become connected to surrounding forests.
This annual flood pulse serves as a giant mixing bowl,
transferring vital sediments and nutrients and providing a
highway for fish migration. [i]Dam projects sever these
essential connections, increasingly fragmenting individual
subwatersheds and undermining the health of the whole Amazon
system.
[/i]
Dams are not the only threat to watershed health. The region
continues to be at risk from [i]deforestation, mining and
hydrocarbon extraction, and climate changes[/i], all of which
may change the annual flood pulse and river connectivity.
Economic pursuits tend to increase energy demand, which drives
the construction of more hydroelectric dams in the region. But
these cumulative impacts are often ignored in environmental
policies governing dam construction. Environmental impact
assessments only consider the effects of individual projects,
making it virtually impossible

The Amazon Basin spans seven nations, which is perhaps the
biggest challenge to holistic watershed management. Healthy
river systems depend on connectivity and do not respect
political boundaries. In many cases, economic development
activities in one country can incur environmental costs in
another, yet there is not an overarching policy framework to
help coordinate management activities across country boundaries.
Developing such a multinational framework is both the biggest
challenge and the biggest opportunity for conserving Amazon
freshwater ecosystems and supporting the productive fisheries
and human populations that depend on them.

at some point somebody had a dam that generated water power
nearby. But so far I have not uncovered the history of the local

Eddie,
If your head is too low, there are still ways to get small scale
hydro power. Forget the math for sufficient head for a moment.
All you need is 3 or four gallons per minute of MOVING water.
I think you have that, do you not?
There are two ways to handle that.
1. A bullet shaped submersible electric generator is fastened to
a post in the stream. You then use that electricity to run an
electric centrifugal pump from the stream to a reservoir.
2. Skip the electric generator and put a hydraulic ram pump in
the stream to pump water up to a reservoir. Ram pumps can, with
very low stream velocity, pump water up as high as 40 FEET!
This is a 1973 article but the principle involved in hydraulic
ram pumps is the same. Perhaps they are cheaper now than they
were then:
The Hydraulic Ram Pump: Perpetual Motion for the Homestead
Although water won't run uphill, some exceedingly clever soul
discovered a long time ago that H2O can be persuaded to pump
itself in that general direction. The hydraulic ram pump makes
it possible.
--- Quote ---
> ... if your property contains a spring, creek, small stream,
or other source with a flow of at least three gallons per minute
(gpm) you can probably solve your problem easily and
inexpensively with a hydraulic ram pump.
--- End Quote ---
--- Quote ---
>
> All that time the device has been pumping clear, cool spring
water up over a 25-foot hill—a distance of 150 feet—and into our
farm pond, without the use of any fuel whatsoever. In short,
we're getting about 500 gallons of water per day at an operating
cost of zero ... and we expect this to continue for ten years or
more.

These pumps use ZERO fuel of ANY kind (aside from the energy
used to make the metal and valves, of course).
