H E G O V E R N M E N T O F
Newfoundland and Labrador
has announced details of a
deal agreed between Nalcor Energy
and Emera Inc that will result in the
development of the 824MW Muskrat
Falls scheme, the rst phase in the
3074MW Lower Churchill River hydro-
electric development.
Announcement of the deal – which
complements a partnership already
in place between Nalcor and the Innu
Nation – was made in St. John’s
yesterday by the Honourable Danny
Williams, Premier of Newfoundland
and Labrador, the Honourable
Darrell Dexter, Premier of Nova
Scotia, the Honourable Kathy
Dunderdale, Minister of Natural
Resources, Ed Martin, President
and CEO of Nalcor Energy, Chris
Huskilson, Chair and CEO, Emera
Inc., Joseph Riche, Grand Chief
of the Innu Nation and Sebastian
Benuen, Chief, Sheshatshiu Innu
First Nation.
“This is a day of great historic
signicance to Newfoundland and
Labrador as we move forward with
development of the Lower Churchill
project, on our own terms and free
of the geographic stranglehold of
Quebec which has for too long deter-
mined the fate of the most attrac-
tive clean energy project in North
America,” said Premier Williams.
“The benets of this project for our
province will be enormous includ-
ing thousands of jobs and billions of
dollars of economic activity.
“From day one, our government
has taken a long-term, strategic
approach to developing this project.
Our priorities have remained stead-
fast; that is to achieve maximum
benefits for our people, and to
secure stable rates and markets with
a good return for the people of this
province. This agreement achieves
these goals and also solidifies a
mutually benecial partnership with
Emera Inc. and the province of Nova
Scotia. Today marks the beginning of
a new era of Atlantic Canadian coop-
eration and together we are telling
the marketplace both in Canada and
the United States that badly needed
competition in the hydroelectric mar-
ketplace is on the way.”
The Lower Churchill River system
is comprised of Muskrat Falls with
824MW of power and Gull Island
with 2250MW. Phase two of the
project will be the development of
Gull Island for which construction is
expected to start several years after
Muskrat Falls.
The Muskrat Falls development
will see power being transmitted
from Labrador across the Strait of
Belle Isle for use on the island of
Newfoundland. Power will be availa-
ble for recall use for industrial devel-
opment in Labrador. Nalcor will then
transmit surplus power from the
island to Nova Scotia Power, a sub-
sidiary of Emera, across the Cabot
Strait into Lingan, Nova Scotia
“This is a historic day for Nova
Scotia, and all of Atlantic Canada,”
sai d Prem i er Da r re l l Dex t er.
“Through this partnership, Nova
Scotia is taking a major step for-
ward as an international leader in
renewable energy. Today’s agree-
ment will create thousands of new
jobs; it will stabilize energy prices
for Nova Scotia families and busi-
nesses well into the future; and it
lifts the idea of Atlantic cooperation
off the page and turns it into fun-
damental action, building a more
prosperous nation.”
“This configuration is the most
economic and reliable option to meet
Newfoundland and Labrador’s needs
over the coming years and opens
the doors for the province to begin
reaping the export benets of our
wealth of clean, renewable resourc-
es,” added Ed Martin, President and
CEO, Nalcor Energy. “This strategic
partnership with Emera creates sig-
nicant opportunity today and well
into the future as it will assist in
building stronger interconnections
among the four Atlantic Provinces
and the northeastern U.S. enabling
all to benet from the wealth of envi-
ronmentally friendly, affordable and
sustainable power Newfoundland
and Labrador and the rest of the
region has to offer.”
Newfoundland and Labrador Hydro
(NLH), a subsidiary of Nalcor Energy,
is mandated to forecast electricity
requirements in the Canadian prov-
ince and bring forward the least
cost, long-term option for meeting
these requirements. As a result of
growing provincial demand for elec-
tricity, NLH evaluated alternatives
to develop new generation sources.
It assessed alternatives and found
the Muskrat Falls project with a
transmission link to the Island to
be the least cost alternative. The
Muskrat Falls option is also more
environmentally acceptable than
maintaining an ‘isolated’ island
power system. Once the Muskrat
Falls development is operational,
the energy price structure in the
province will be stable and lower
cost for consumers over the long-
term and the province will avoid the
volatility associated with the price
of oil.
Before the project is sanctioned
for construction however, a number
of issues still need to be concluded,
including: the release of the gen-
eration and transmission projects
and the transmission project from
environmental assessment proc-
esses; nal ratication of the Lower
Churchill IBA and Churchill Falls
Redress Agreement; conversion of
the Nalcor/Emera term sheet into
formal legal agreements; finaliza-
tion of nancing; and completion of
pre-front end engineering work.

Alaska selects site for Railbelt hydro project
T
HE ALASKA ENERGY AUTHORITY
(AEA) has named the preferred
location for a new large hydro-
electric project in the US state as
the Low Watana site on the Susitna
River.
Earlier this year, the Alaska
Legislature provided funding to AEA for
the preliminary planning, design, per-
mitting and eld work for the Susitna
project, together with a project on
Chakachamna lake, as well as Glacier
Fork and other hydroelectric projects
on Alsaska’s Railbelt. Primary focus
was directed on the two large projects
- Susitna and Chakachamna - but AEA
has now selected Susitna as the main
project with Chakachamna to be con-
sidered as an alternative.
“Our goal has been to identify the
project that has the best chance of
being built,” said AEA Acting Executive
Director Mike Harper. “A large hydro-
electric project for the Railbelt should
not only provide cost-effective, reli-
able, long-term power; it must help the
state meet its goal of producing 50%
of our power from renewable resourc-
es by 2025. We believe the Susitna
Project does all this.”
AEA and its consultants evalu-
ated cost, potential environmental
impact and energy production of
both projects. Additionally, the eval-
uations included analysis of both
projects to determine if either has a
fault that would prevent its licensing
and construction.
At this time, neither project has
been found to have such a fault.
However, the studies determined that
while the engineering development of
the Susitna Project would cost approxi-
mately 50% more than Chakachamna,
there is greater risk of signicant cost
overruns at Chakachamna because of
the steep terrain and extensive under-
ground work required.
The evaluations further concluded
that the Chakachamna hydroelectric
project has greater environmental
impact because the project would
require a cross-basin water trans-
fer. It was also determined that
Chakachamna energy production
would be substantially reduced to
allow enough water ow to protect
the lake’s signicant salmon runs.
In summary, it was concluded that
the Susitna hydroelectric project
would produce two to three times
more energy and at a lower per unit
cost; that Susitna has less likely envi-
ronmental effects; that the project
has fewer licensing and permitting
complexities; that it can start sooner
and involves simpler construction;
and that it has a lower long-term
operational risk factor.

AVE ENERGY DEVELOPER
Aquamarine Power says
that the injection of £11M
of funding into its business marks a
signicant endorsement of its Oyster
technology.
The rm has announced that it has
received £8M of funds from ABB and
a further £3M from existing share-
holders, which include SSE Venture
Capital, the ventures unit of Scottish
and Southern Energy.
It says that the funding will help
it commercialise the Oyster wave
energy machine, which is a large,
clamshell-shaped device.
The rst Oyster unit was installed
and connected to the grid last year in
Scotland. Aquamarine in also working
on a second-generation device.
“This is a game-changing moment for
our company and for the UK’s marine
energy industry,” says Aquamarine
Power CEO Martin McAdam.
“ABB is a global leader in power
and automation technologies and
they have taken a strategic deci-
sion to invest in Oyster technology,”
continued McAdam. “Through work-
ing together ABB will gain an early-
mover advantage in our wave energy
technology, whilst we will be able to
access ABB’s technical, research and
engineering expertise and utilise their
global supply chain network.
“Our companies are very differ-
ent in size but similar in ambition.
This is a strategic partnership with
the shared goal of accelerating the
commercialisation and deployment
of Oyster wave energy technology
around the world.”
Scotland’s First Minister Alex
Salmond said that the investment
represented “clear and tangible evi-
dence of the continued growth and
condence in Scotland’s renewables
industry and the contribution that
wave power can make to clean, green
energy generation and reductions in
harmful global carbon emissions”.
The investment in Aquamarine
Power was made by ABB Group’s
technology investment arm, ABB
Technology Ventures.
“Wave energy is primed to become
an important part of the world’s
renewable energy portfolio,” said
Brice Koch, head of ABB Marketing
and Customer Solutions. “This invest-
ment reects our belief in its techni-
cal viability, and our confidence in
Aquamarine Power’s technology and
its management team.”
Investment boost for
Aquamarine Power
From the Editor
Dear readers,
It’s hard to believe that 2010 is already at an end –
it seems like only weeks ago we were welcoming in
the new year. But what a year this has been for the
hydropower industry. A number of new large hydro
projects have begun construction, while there has
been a surge in small hydro developments. Financial
institutions are also showing a greater interest in
renewable energy technologies, which can only mean
good things for the industry, while support for pumped
storage schemes is at an all-time high, thanks to the
major role it can play in the renewable mix.
In my mind however, one of the most important
developments this year has been the recent release by
the International Hydropower Association of the GHG
Measurement Guidelines for Freshwater Reservoirs,
a landmark publication and the current standard on
measuring Greenhouse Gas (GHG) emissions from
reservoirs.
This publication is important, because, as the IHA
stresses, it offers, for the first time, a comprehensive
tool to assess the GHG status of Freshwater reservoirs,
including definitive guidance on measurement and
qualification of emissions resulting from the formation
of reservoirs. Guidance covers: concepts and processes
involved in making such measurements; the approach
to conducting field measurements; and guidance on
calculating results.
By providing the tools required to determine net GHG
emissions in a selected set of reservoirs, IHA’s intention
is to ensure that the results gained will be utilised to
develop predictive tools, thereby avoiding the necessity
of such intensive field measurements in the future.
You can read a more detailed report on the guidelines
in our insight article on p10-12, and I’m sure many
of you will find this publication a very useful tool with
regards to your dam and hydro projects.
Also in this issue you’ll also find details on the top
five developments that IWP&DC believes will have the
biggest impact on the hydropower industry over the
next few years. Take a look at the article on p20-22
and let us know if you agree with our choices, or even
suggest other developments you think will likely have
the biggest effect on the industry.
I look forward to hearing your views and wish you all a
happy holiday and prosperous new year!
Best wishes

Deal reached for Condit Dam
decommissioning project
U
S UTILITY PACIFICORP HAS
reached a tentative agree-
ment with Klickitat County and
Skamania County concerning decom-
missioning of the Condit Hydroelectric
Project located on the White Salmon
River in southwestern Washington.
In return for various terms from
PaciCorp, the counties will not oppose
the decommissioning of the project.
“Klickitat and Skamania Counties
participated fully in the review of Condit
Dam removal in State and federal
environmental studies and submitted
comments to a host of governmental
agencies, including the Washington
State Department of Ecology,” com-
mented Klickitat County Commissioner
Dave Sauter. “PaciCorp took seriously
the Counties’ concerns and incorporat-
ed a number of the recommendations
into the dam removal plan.”
Jamie Tolfree, Chair of the Skamania
Board of Commissioners, added that
“the Counties will now look to the fed-
eral agencies and the Department of
Ecology to ensure that dam removal is
carried out consistent with federal and
state requirements.”
Under general terms of the agree-
ment, PaciCorp will pay the counties
$675,000 to offset decommissioning
impacts to the local community, trans-
fer the project’s hydroelectric water
right to Klickitat County, and complete
measures to protect the structural
integrity of Northwestern Lake Bridge.
In return, the counties will not
oppose PaciCorp’s efforts to remove
Condit Dam and associated facilities
as proposed by PaciCorp; complete
noxious weed control in the project
area after decommissioning; and,
work with PaciCorp to implement a
public safety plan during the decom-
missioning project.
The next step is to obtain a Section
404 permit from the US Army Corps
of Engineers, which the company origi-
nally applied for in July 2004.

Scottish Power and E.On to
collaborate on wave power
I
ts plans to collaborate with Scottish
Power Renewables on the testing of
two wave power devices in Orkney,
Scotland, are vital to the efforts to
bring the technology to market, says
energy giant E.On.
The two energy companies have
announced that they are to join
forces to trial two Pelamis wave power
machines at the European Marine
Energy Centre (EMEC) in Orkney.
The news follows an announce-
ment from E.On in early November
that the rst of those “P2” machines
generated power for the rst time.
The second machine will be built
for Scottish Power Renewables and
will be installed alongside the first
device in 2011.
The two companies will use
the information gathered from the
trials to look at larger, more
commercial schemes.
“If we’re to bring marine energy to
the market then it’s absolutely vital
that we take a collaborative approach
to ensure this technology is able to
full its potential and contribute signif-
icantly to the UK’s renewable future,”
said Amaan Lafayette, Marine Energy
Manager at E.On.
“That’s why we’re delighted to
be working with Scottish Power
Renewables on this important project
which will give us, and the industry,
vital information about how best to use
these technologies going forward.”
E.On installed the rst P2 device –
named the Vagr Atferd – at EMEC’s
Billia Cross site earlier this year. It is
the rst P2 to be tested anywhere in
the world.
“This is the rst stage of a testing
programme that is scheduled to last
around three years. This is a crucial
time for us and will help to determine
what we need to do to ensure that
marine energy makes the transition
from a potential player in the renewa-
bles market to commercial deploy-
ment, not just in the UK but around
the world,” said Lafayette.
The P2 machine is 180 m long
and weighs around 1300 tonnes.
The motion of the waves produces
electricity by driving a set of hydraulic
rams at the hinged joints, which link
the cylindrical sections of the device.
E.On successfully applied for
two 50 MW tidal sites off the coast
of Orkney as part of the Crown
Estate’s recent Round 1 Marine
leasing programme.
Alstom inaugurates ocean energy
business in Nantes, France
A
lstom inaugurated the new
premises of its Ocean Energy
activities in Nantes, France, in
early December, marking the occa-
sion by revealing the characteristics
of BELUGA 9, the group’s tidal elec-
tricity-generating turbine, which will
undergo its rst tests in 2012, in the
Bay of Fundy, Canada.
Alstom’s Ocean Energy Business
was created in 2009 when Alstom
signed a technology-licensing con-
tract with Canadian company Clean
Current. The business will now be
located on the island of Nantes (Ile de
Nantes) under the direction of Philippe
Gilson, Alstom Hydro’s Ocean Energy
Manager. The role of his team will be
to design, manufacture and market a
new generation of tidal turbine gener-
ators that can produce electricity from
tidal currents.
BELUGA 9, intended for very pow-
erful currents (up to 4.5m/sec, or 9
knots, on the surface during spring
tides) will be Alstom’s rst tidal tur-
bine generator. Once mounted, it will
have a diameter of 13m and a total
height of 20m, the equivalent of a
six-storey building. It will be suited to
sites at depths of 30m or more, such
as in the English Channel.
In addition, the Nantes division
has just begun preliminary studies for
the development of a second model,
intended for sites at greater depths
where the tide is less powerful; test-
ing should begin in Brittany in 2013.
Rainpower enters Swedish hydropower market
N
orwegian technology com-
pany Rainpower has set up
a new subsidiary company in
Sweden, Rainpower Kristinehamn,
and has also entered into a coopera-
tion agreement with engineering rm
KTAB to become a fully integrated pro-
vider of hydropower technology and
services in the Swedish market.
“Establishing Rainpower in Norway
has been very successful, and we
feel that the time is right to take
a look at the exciting hydropower
market in Sweden,” said CEO Svein
Ole Strømmen. “KTAB is an engi-
neering company that has developed
impressive hydropower expertise in
Kristinehamn. This expertise com-
bined with a highly qualied technical
team in Kristinehamn and innovative
research environment in Norway will
create a competitive total supplier of
hydropower services in Sweden for
planning, production, maintenance
and service. We have great faith in
our Swedish commitment.”
Since it was set up in 2007,
Rainpower has developed proprietary
turbine technology at its hydropower
laboratory in Trondheim. Through its
establishment in Sweden and the
expertise this will bring to the group,
Rainpower says it will soon be able to
develop lower-pressure turbines, more
appropriate for the Swedish market.
To drive the Swedish activity
Rainpower is appointing around ten
key personnel with extensive expe-
rience in the Swedish hydropower
industry. Casper Vogt-Svendsen will
be managing director of the subsidi-
ary company.

South Australia. The company
also expects to signicantly grow
its Australian portfolio.
“The appointment of a CEO
for our Australian operations
and creating a more formalised
management structure is a timely
step for our maturing business in
Australia,” said Meridian Energy
Australia Chairman Peter Lowe.
Lowe said the Board believed
Mr Burge’s broad experience in
both the energy sector and in stra-
tegic corporate development roles
made him the ideal candidate for
the position of CEO at Meridian
Energy Australia.
Commenting on his appoint-
ment Burge said: “Meridian
Energy Australia has a unique
opportunity to be a leader in
the Australian renewable energy
sector. We already have operating
assets in Australia as well as our
commitment as a 50% JV partner
in Australia’s largest wind farm at
Macarthur. We expect to grow
this significantly, supported by
the commitment, environmental
credentials and resources of our
New Zealand parent company

10 DECEMBER 2010 INTERNATIONAL WATER POWER & DAM CONSTRUCTION
INSIGHT
F
OR a long time, dams were consid-
ered as a clean, emissions-free way of
generating energy. However, recent
studies have produced conflicting
results, some suggesting that reservoirs may
be signicant sources of greenhouse gases
(GHG), others indicating a small impact on
the total carbon emissions.
To quantify the change of GHG uxes in
a river basin caused by the creation of a res-
ervoir requires consideration of exchanges
before and after its construction. However,
there has been no scientic consensus on how
to measure the GHG status of freshwater res-
ervoirs.
This lack of consensus has impeded
progress in decision-making on specific
activities. For example, scientic guidance
is needed to support the construction of
national GHG inventories; develop methods
(measurement and predictive modelling) of
establishing the GHG footprint of new water
infrastructure projects; and to quantify more
precisely the carbon offsets of hydropower
projects for GHG emission trading. More
generally, policymaking on energy, water and
climate action is compromised by the cur-
rent lack of understanding. This has a global
impact, especially on planning in developing
countries.
Despite strong efforts to build consensus in
assessing the GHG status of reservoirs, many
uncertainties have remained. Specic problems
have been the lack of standard measurement
techniques, limited reliable information from
a sufcient variety of sources, and the lack of
standard tools for assessing net GHG exchange
from existing and planned reservoirs.
As a consequence, comparisons between
the available results are not an easy task,
requiring intense interpretation of the data
and often leading to unreliable estimates of
the actual inuence of freshwater reservoirs
on the emission of GHG.
The main difculties in the current stage of
knowledge are:
r The great majority of the available litera-
ture data are large gross emissions from
tropical young reservoirs, including natu-
ral and unrelated anthropogenic sources.
Consequence: overestimates of the GHG
emissions and a bad perception of the real
role of freshwater reservoirs over climate
change.
r There was no agreed procedure to estimate
the net emissions of reservoirs, and data
have not been obtained in a standard proce-
dure (each study uses different measurement
procedures and equipment). Consequence:
comparisons between the available results
are not an easy task, requiring intense inter-
pretation of the data.
r It is still difcult to have a representative
sample of existing and planned reservoirs
(most existing studies have been made in
tropical young reservoirs, more prone to
large emission rates). Consequence: GHG
emissions from reservoirs at the global scale
are subject to large uncertainties.
The unesco/iha ghg research

The UNESCO/IHA GHG Research Project

(the project), hosted by the International
Hydropower Association (IHA), in collabo-
ration with the International Hydrological
Programme (IHP) of UNESCO, came as a
response to these challenges and needs. It
aims to improve understanding on the impact
of reservoirs on natural GHG emissions in a
river basin, obtaining a better comprehen-
