Development of the Atlin hydro project

ARMAC is Montanhydraulik‘s computer-

controlled ﬂ ow-level-regulation and control

system, operating successfully in many hydro

dam projects in India. It measures water inﬂ ows

into the reservoir every 15 minutes. Using 80-

to 100-year water ﬂ ow data, it works out the

optimum combinations of water levels and

gate openings for the speciﬁ c time of year,

and commands the gates to open or close.

ARMAC can also be used to regulate flows

through several reservoirs and dams on the same

river, communicating the data, including hydraulic

system health, via VSAT or GPRS.

ARMAC is part of Montanhydraulik‘s turnkey

solutions for hydromechanical and electrohydrau-

lic systems. We offer the complete system with

hydraulic cylinders, aggregates, electrical control

and installation.

STUDY RELEASED BY THE

National Hydropower Association

says that the US hydro power

industry could install 60,000MW of

new capacity by 2025, creating up to

700,000 new jobs.

The US industry today has

100,000MW of installed capac-

ity. The Job Creation Opportunities

in Hydropower report, prepared by

Navigant Consulting, says an addition-

al 23,000-60,000MW could be added

through new technologies, efﬁciency

improvements, and research and

development. This additional capac-

ity represents only 6-15% of the total

untapped hydro resource potential in

the country – currently estimated at

400+GW.

The study’s findings prompted

Pennsylvania Governor Edward

Rendell to call on policymakers to

support development of hydro power,

America’s largest renewable energy

resource. “It’s time to invest in renew-

able energy resources that generate

electricity in this country and that

provide jobs for Americans,” he said.

“Hydro power presents elected ofﬁ-

cials across the country an opportu-

nity to bring thousands of long-term,

family-wage jobs to our states.”

Voith Hydro CEO Mark Garner

agreed. “This study conﬁrms what our

experience at Voith Hydro has already

shown – investments in hydro lead

directly to good-paying, long-lasting

American jobs. We have seen 27%

growth in permanent employees in

the past two years, and as the indus-

try continues to grow, we have a huge

potential to create additional clean,

family-wage jobs across the US.”

The US hydro power industry cur-

rently employs approximately 300,000

people. As the industry continues to

grow, every region will see additional

good jobs and new economic oppor-

tunities.

“The hydro power industry is pre-

pared to double its current capacity

of clean, domestic, renewable water-

power resources,” said NHA President

Andrew Munro of Grant County (WA)

Public Utility District. “Hydro power

offers tremendous potential for

America to double is renewable

energy production, provide reliable

electricity for American families, and

create thousands of new jobs.”

According to James Lautar, inter-

national representative for the

International Association of Machinists

and Aerospace Workers, “Hydro power

is already an important source of good-

paying, high-quality jobs for workers

across the country. A national invest-

ment in hydro will help grow American

jobs for decades to come.”

In addition to providing clean,

affordable, domestic electricity, hydro-

power also helps foster the growth of

other renewable energy resources. In

fact, at a recent green jobs event in

Pennsylvania, US Energy Secretary

Steven Chu called hydro power’s dual

roles “an incredible opportunity” to

expand the country’s clean energy

resources.

To help encourage the develop-

ment of new hydro, the NHA is calling

on Congressional leaders to:

mental, and economic policy,” NHA

Executive Director Linda Church Ciocci

said. “NHA stands ready to work with

all policymakers who pursue develop-

ment of America’s critical hydro power

resources.”

Repairs to keep Glendoe shut down until 2010

HE SEVERITY OF THE ROCKFALL

near the top of the headrace

tunnel at the Glendoe hydro

power plant will keep the facility shut

down until ‘well into’ next year, said

the owner, Scottish and Southern

Energy (SSE).

The UK energy utility said the

rockfall was ‘very substantial’ but

is conﬁned to near the top of the

power tunnel. No details were given

for the cause of the tunnel failure.

SSE said planning is underway to

establish the best method of repair-

ing the power tunnel but added that

Glendoe power plant would not gen-

erate for many months – ‘well into

2010 at the earliest’.

The rockfall was discovered in

August after the power tunnel was

partly blocked. No damage was

caused to the equipment in the

underground power plant.

Glendoe only began operations

at the end of 2008. At 100MW, it

is the UK’s biggest conventional

hydro power plant built in over half

a century.

The project involved construc-

tion of more than 16km of tunnels,

mostly by drill and blast but the

6.2km long headrace between the

powerhouse and reservoir area was

bored by TBM. It is still unclear if

the area affected by the rockfall

was excavated by TBM or of some

drill and blast was used locally.

Geology along the tunnels is

HARD ROCKnSCHIST AND QUARTZITE

with minor faults. Lining support

comprised bolts, steel ribs, mesh

and shotcrete, used as required.

The project was constructed under

a design and build contract by Hochtief

Glendoe JV, which is led by German

contractor Hochtief and include Poyry

as the designer. The client’s adviser

is Jacobs.

In other news, SSE unit SSE

Generation has submitted a planning

application to expand the Sloy hydro

power plant, in Scotland, by 60MW.

The application is to build a

pumped storage plant to add a further

100GWh of electricty to annual gen-

eration. Current capacity is 152MW.

CanHydro accepts increased TransAlta offer

ANADIAN HYDRO DEVELOPERS

and TransAlta Corporation

have entered into a defini-

tive pre-acquistion agreement after

TransAlta agreed to increase its orig-

inal cash takeover offer of C$4.55

per share to $5.25.

In a statement from the compa-

nies, it was announced that the

amended offer, which has a total

value of approximately C$1.6B,

has the unanimous support of

the Boards of Directors of both

Canadian companies.

“We believe this transaction

delivers certain and fair value to

Canadian Hydro Shareholders while

providing TransAlta sharehold-

ers with both near and long term

value,’ said TransAlta President

and CEO Steve Snyder, adding

that the acquisition will acceler-

ate TransAlta’s growing renewable

portfolio.

On a combined basis, TransAlta

and Canadian Hydro will have net

generation capacity of 8657MW in

operation. The renewables portfolio

will include 1900MW in operation,

or 22% of the combined portfolio.

In addition, there is 543MW under

construction and nearly 500MW in

advanced-stage development.

Canadian Hydro Board Chair

Dennis Erker said, “Over the past

two months, the Canadian Hydro

Board and its advisors have con-

ducted a thorough process to

review and consider the full range

of options for enhancing share-

holder value, including alternative

proposals. We believe the revised

offer from TransAlta provides our

shareholders with a premium and

liquidity, and we are encourag-

ing our shareholders to accept

this offer.”

The Amended Offer is subject to

certain conditions, including the

acquisition by TransAlta of at least

66 2/3 per cent of the outstanding

Canadian Hydro common shares.

Klamath dams agreement unveiled

HE 28 PARTIES NEGOTIATING

the fate of dams on the Klamath

River have now released

the highly anticipated Klamath

Hydroelectric Settlement Agreement

(KHSA), detailing water management

and dam removal plans for the river

basin in the US states of Oregon

and California.

Over the coming weeks Klamath

Basin Tribes, counties, conserva-

tion groups, fishing groups, and

farming and ranching organizations

will consider the pros and cons of

the Agreement and decide whether

or not to support it.

The KHSA would be complement-

ed by the implementation of a com-

panion agreement, the Klamath

Basi n R estorat ion Ag reement

(KBRA). Whereas the KHSA focuses

on the fate of US utility PaciﬁCorp’s

lower four Klamath River Dams, the

KBRA signiﬁcantly increases water

ﬂows for ﬁsh, provides greater reli-

ability of irrigation water delivery,

undertakes Basin-scale habitat

restoration, and makes critical

economic investments to ensure

the economic viability of Basin ﬁsh-

ing and farming communities into

the future.

“This Agreement represents a

major step toward restoring the

health of the Klamath River. We

look forward to working with all

Tribal, agricultural, and fishing

communities in the Klamath Basin

on implementing these solutions,”

said Troy Fletcher, negotiator and

Yurok Tribal member.

The KHSA provides a pathway

that would lead to dam removal

in 2020 following an analysis by

the US Secretary of the Interior to

determine whether dam removal

is indeed to the beneﬁt of ﬁsher-

ies resources and in the public

interest. In addition, the safety of

dam removal must be scrutinized

through a public environmental

review process consistent with all

applicable state and federal envi-

ronmental laws.

“Of course we’d like to see the

dams removed tomorrow, but the

reality is we must make sure dam

removal is as safe as preliminary

assessments suggest and that it

can be done cost effectively,” said

Steve Rothert, California Director

for American Rivers. “For a restora-

tion action that is simply unprec-

edented in scale and scope, this is

actually a reasonable timeline.”

The KH SA is bas ed on the

Agreement in Principle reached

be tw ee n P ac if iC orp , Ore go n,

California, and the federal govern-

ment in November of 2008. It pro-

vides for funding up to US$200M

in dam removal costs by collect-

ing a surcharge from PacifiCorp’s

Oregon and California customers

over the next 10 years. Earlier

this year, the Oregon legislature

auth orize d the cust omer sur-

charge. If necessary, the State

of California would provide up to

$250M more towards the cost

of removal with the total project

costs not to exceed $450M.

Dam owner PaciﬁCorp appreci-

ates the approach in the Agreement

as well. PacifiCorp Chairman &

CEO, Greg Abel described the

agreement as a “balanced and

reasonable outcome that best

protects the interests of our cus-

tomers, while achieving the policy

objectives of the states and federal

government, as well as helping to

peacefully resolve numerous con-

ﬂicts in the Klamath basin.”

The release of the proposed

Agreement marks a significant

shift in attitude for many in the

basin. Over the past 20 years

the Klamath has been marked by

bitter and acrimonious debate. The

various communities had targeted

one another with lawsuits and pro-

tests, often marked by acts of civil

disobedience, in a failure to truly

resolve issues pertaining to water

rights, river flows, and economic

development.

“Once we decided to stop ﬁghting

and start talking, we realized the

opportunities provided by collabo-

ration and coalition building,” said

Jeff Mitchell, council member for

the Klamath Tribes of Oregon. “We

haven’t seen salmon in our country

for 90 years; this Agreement rep-

resents our best chance of ﬁnally

bringing the salmon home to the

Upper Basin.”

In coming weeks, participating

governments and organizations

will be considering whether to for-

mally sign on to the Agreement. If

a critical mass can be reached, the

groups hope to introduce legislation

to implement the companion agree-

ments by the end of the year.

Carnegie selects wave project site

E AS I BI L I TY S TU D IE S BY

Carnegie Wave Energy Ltd has

indicated that waters off Garden

Island, near Perth and Rockingham,

would be the most suitable loca-

tion for the company’s ﬁrst Western

Australian small scale commercial

demonstration wave energy project.

For the past 12 months, Carnegie

has been undertaking feasibility stud-

ies on potential wave project sites

around Western Australia in the mid-

west, south-west and metropolitan

regions under its wave energy inves-

tigation licenses covering waters

throughout the State. The investiga-

tions have been conducted in con-

junction with technical experts Arup,

Atteris, RPS MetOcean and GHD.

The Garden Island site was select-

ed due to its optimum combination

of a range of technical and economic

factors including wave resource char-

acteristics, environmental factors,

pipeline route options, grid connectiv-

ity, water depth, scale of plant and

deployment and servicing logistics.

Subject to the receipt of all approv-

als, the small scale commercial

demonstration project will be a 5MW

scheme, and will utilise Carnegie’s

$12.5M LEED grant from the Western

Australia Government announced ear-

lier this year, subject to the ﬁnalisa-

tion of contracts.

The primary aim of the project is

to demonstrate the CETO technol-

ogy in commercial operation for the

ﬁrst time. However, it will also deliver

Carnegie its first project-based rev-

enues from the sale of power.

The Project will be deployed in

two stages; the ﬁrst will involve the

deployment of single autonomous,

commercial scale CETO units. These

stand-alone units consist of a CETO

unit coupled to energy dissipation

and instrumentation systems to vali-

date the energy delivery performance

of each unit. The performance data

is transmitted back to Carnegie’s

Fremantle facility for monitoring and

analysis. Planning, design and approv-

al aspects of Stage 1 began at the

start of 2009 and Stage 1 is expected

to be completed in 2010.

The second stage of the project is

the deployment of the remaining CETO

units and associated balance of plant

including pipework and an onshore

power generation system required for

the 5MW plant. This is expected to

occur in 2011.

EW ZEALAND’S MERIDIAN

Energy has been granted water-

only consents for its proposed

hydro generation tunnel concept on

the north bank of the Waitaki river,

subject to certain conditions.

The company’s North Bank Tunnel

Concept is a hydro generation proposal

taking water from behind the Waitaki

dam and discharging it back into the

Waitaki river about 34km downstream

near Stonewall. It will generate an aver-

age of between 1100GWh and 1400

GWH annually.

The decision to approve water-only con-

sents for water take, use and discharge,

follows an 11 day Environment Court hear-

ing in June and July this year which occurred

as a result of appeals of the Environment

Canterbury consents granted in 2008.

The decision says consent will be granted

subject to further work to address manage-

ment and mitigation issues in the areas of

wetlands and braided river birds.

To advance the project Meridian will

also have to apply for land-use and

construction consents for the build-

ing of the tunnel and power station.

Obtaining these consents is expected

to take several years.

Once all consents have been secured

and a full feasibility engineering study

has been completed, Meridian will be in

a position to commit to the design and

construction of the project. This is not

likely to occur until at least 2012.

S UTILITY TENNESSEE VALLEY

Authority (TVA) is raising the

elevation of four of its dams to

help prevent overtopping in a ‘worst

case’ extreme weather event, follow-

ing a recent update of ﬂood forecast-

ing calculations.

The utility will place temporary,

wall-like structures on top of earthen

embankments of the Fort Loudoun,

Tellico, Cherokee and Watts Bar dams

in East Tennessee, raising the top

elevation of each embankment about

4ft (1.2m). The extra height would pre-

vent water from overtopping and dam-

aging the earthen embankments.

“TVA evaluates its dam safety

program regularly,” said TVA River

Scheduling General Manager Chuck

Bach. “As technology and stand-

ards evolve and more or better data

becomes available, we update our

ﬂood forecasting calculations to deter-

mine whether we need to change our

flood control operation or modify

our dams to better protect public

safety.”

A recent update of TVA’s river mod-

elling program determined that the

maximum ﬂoodwater elevations could

be higher than previously calculated

if a highly unlikely, worst-case winter

rainfall were to occur in the upper part

of the Tennessee Valley watershed.

Bach stressed that this action

is not related to recent rainfall that

caused ﬂooding in unregulated tribu-

tary streams, which was only a frac-

tion of the amount used to forecast a

‘worst case scenario’.

“The magnitude of rainfall used in

the calculations has never actually

occurred in the region, but it could

produce floodwaters that would be

higher than previously thought,” said

Bach. “Although the probability of

such an event is extremely rare, TVA

must design and operate its dams to

safely withstand such events.”

He said structures to raise the

embankments are scheduled for

installation by 1 January 2010,

because large regional floods are

most likely to occur in winter and

early spring. The interim measures

are expected to remain in place until

long-term, permanent solutions can

be identified, evaluated and imple-

mented.

To calculate the maximum flood

levels in its river modelling, TVA

assumes an extremely large storm

within the watershed area being eval-

uated, which is critically centered to

produce maximum ﬂood levels.

The higher predicted ﬂood levels

are the result of improved data gath-

ered in part from experience gained

during large storms, revised analysis

of spillway water ﬂow rates at dams,

and higher initial reservoir levels in

TVA’s new reservoir operating policy.

CEAN POWER TECHNOLOGIES

(OPT) has signed an exclusive

agreement with a Japanese

consortium comprising Idemitsu Kosan

Co, Mitsui Engineering & Shipbuilding

Co and Japan Wind Development Co to

develop a demonstration wave power

station in Japan.

The initial phase of the project will be

for OPT and the Consortium to work with

the Japanese government to increase the

recognition of wave power in Japanese

energy policy, and to identify favourable

sites for OPT wave power stations.

Subject to the successful identiﬁca-

tion of a site and completion of eco-

nomic assessments, the parties plan to

enter into an agreement to build a dem-

onstration plant with up to three of the

OPT’s PowerBuoys units. The trial plant

would provide the basis for the expected

building of a commercial-scale OPT wave

power station with an initial capacity of

10MW or more.

Under the anticipated agreement

to build the demonstration plant, OPT

will sell the equipment for the power

station to the Consortium. For sub-

sequent wave power stations, the

Consortium will provide manufactur-

ing and maintenance of the power sta-

tions and on-going plant operations,

while OPT will provide its PowerBuoy

technology under license.

Request for proposals

Agriculture and Agri-Food Canada

(AAFC) has released a request for

proposal inviting qualified and

experienced ﬁrms to submit a pro-

posal for Duncairn Dam – Service

Contract No 9 – Dam Safety Review

Phase 1 – Dam Break Analysis and

Inundation Mapping.

AAFC is endeavouring to align

activities and management of dams it

owns and is responsible for, with cur-

rent industry standards. The indus-

try standards for dam ownership

are outlined in the Canadian Dam

Association (CDA) Practices docu-

ment and are further deﬁned in the

CDA guidelines. Stated therein is the

requirement that dams undergo peri-

odic systematic safety reviews. An

assessment of the potential impacts

of ﬂood passage on the downstream

area is a key ﬁrst step.

For further information on the

RFP contact: Colby Collinge, 1800

Hamilton Street, Room 408, Regina,

SK, Canada, S4P 4L2. Tel: (306) 780

Pakistan

Advance notice

The Pakistan Water and Power

Development Authority (WAPDA)

has invited expressions of interest

for consultancy work on the Warsak

hydroelectric power station in north-

west Peshawar.

Work will involve carrying out fea-

sibility studies, together with prepa-

ration of the detailed design, tender

documents and PC-I for the upgrad-

ing and modernization of the project

on the River Kabul.

The Warsak project was originally

completed in two phases and was

ﬁnanced by the Canadian Government.

The ﬁrst phase, completed in 1960,

consisted of construction of a dam,

irrigation tunnels and installation of

4x40MW power generating units,

together with a 132KV transmission

system. Two additional generating

units each of 41.48MW capacity were

added in 1980-81 in the 2nd phase,

increasing the total installed capacity

of the station to 243MW. The basic

objective of the proposed feasibility

study is to determine the most viable

options to ensure the six units continue

to operate for a further 40-50 years.

Under the project, the required

Consultancy Services will comprise

of four areas with regards to the fea-

sibility study and preparation of the

detailed design and tender documents:

(I) Rehabilitation Works related to

E&M Equipment of Generating Units

(II) Rehabilitation Works related to

Civil Structures (III) Sedimentation

Management Studies and (IV)

Preparation of PC-I of the Project.

The intention of this EOI invitation

is to shortlist suitable consultants/

JVs from which the proposals will be

invited. The JVs should not comprise

of more than four ﬁrms.

Interested firms are advised to

address their submissions or enquir-

ies , if any, to the General Manager

(Hydel), 186-WAPDA House,

Lahore. Tel: (+92-42) 9202288.

Fax: (+92-42) 9202159.

The last date for submission of EOIs is

4 December 2009 up to 14.00 hours

10 NOVEMBER 2009 INTERNATIONAL WATER POWER & DAM CONSTRUCTION

INSIGHT

inohydro’s decision to take control

of the Memve’ele dam project in

Cameroon is just the latest in a long

line of Chinese support for hydro

schemes in Sub-Saharan Africa. While

many of the contracts are undoubtedly

motivated by commercial considerations,

they appear to be part of the Chinese gov-

ernment’s wider policy towards the region.

In a strategy that has been dubbed power

plant diplomacy, Beijing is helping to

develop African infrastructural projects in

an apparent attempt to gain control over a

wide array of natural resources, from oil

and gas to copper and iron ore.

Globeleq had originally planned to

develop the Memve’ele project. The

British company, which is an offshoot

of CDC Corporation (previously called

the Commo nwe al th D eve lopme nt

Corporation), invests in power schemes

in developing countries that can improve

living standards as well as generate prof-

its. It intended to develop the scheme

through its local subsidiary, Sud Energie,

via a build own operate transfer (BOOT)

contract that would see ownership trans-

ferred to the government of Cameroon

after 20 years.

However, Globeleq withdrew from the

scheme in May 2009, less than two years

after signing the BOOT contract. The gov-

ernment appeared to have changed its mind

about the structure of the deal and objected

to the fact that it would take two decades

to secure ownership. Sinohydro signed its

own preliminary agreement to construct

the project in September this year and a

government spokesperson revealed that the

ﬁnal agreement is expected to be completed

in the near future.
