OZENS OF PEOPLE WERE

killed when a dam in Indonesia

overtopped and colla psed fol-

lowing heavy rain on 27 March.

The inflow rate to the Situ Gintung

Dozens dead following dam

collapse in Indonesia

reservoir was beyond the discharge

capacity of the spillway on the Dutch

colonial-era embankment dam, which

led to erosion of the surface and soil.

The resulting collapse created a chan-

nel cutting through the earth structure.

According to the Ministry of Public

Works, the dam collapse resulted in

the release of 1.5Mm

of water from

the reservoir, which is located in

Ciputat, Tangerang, in the southern out-

skirts of Jakarta. The dam is at the

north end of the narrow, V-shaped

reservoir, and most areas around it are

built up including the former flood plain.

Local reports tell of people describ-

ing a wall of water rus hing from the

failed dam, which has been described

at having been 10m high. Figures are

conflicting but, at the time of going

to press, at least 58 people had

been killed by the floodwater, it is

understood.

The ministry said that there was no

fault attributable to human error in the

collapse. It added that heavy rainfall

began in the afternoon of 26 March

and quickly proved to be more than

the reservoir could hold, although

there was no information given on

storage level prior to the downpour.

Reports said that the problems began

for the spillway after appr oximately

four hours of rain.

While emergency repairs get under-

way at the dam, inspections have also

been launched at similar structures.

Originally, the Situ Gintung levee

dam was built on the Pesanggrahan

river to provide irrigation water for rice

fields. It is reportedly most of a cen-

tury old though the ministry said that

rainfall data from 1910-1960s has

been used in sizing capacity needs.

But the ministry has questioned

whether there have been changed pre-

cipitation patterns, possibly related to

climate change, that – together with

landuse changes – put the dam at rel-

atively more risk.

Change in landuse saw the irriga-

tion fields then used to build settle-

ments, which influences the drainage

regime downstream of the spillway,

the ministry said. Reports tell of

people living in very close proximity to

the reservoir.

HE PROVINCE OF BRITISH

Columbia and BC Hydro have

initialled a final agreement with

the Tsay Keh Dene Band that, o n c e

ratified, will address the longstand-

ing grievances from the creation and

operation of the W.A.C. Bennett Dam

and Williston Reservoir in the Peace

River Vall ey region, Aboriginal

Relations and Reconciliation Minister

Michael de Jong has announced.

“Initialling this agreement is anoth-

er important milestone along the path

to establishing a New Relationship

with Tsay Keh Dene,” said de Jong.

“The Chief and Council have demon-

strated incredible perseverance to

reach this pivotal stage in negotiations

and I congratulate them for taking this

step as we move forward towards

achieving reconciliation of decades of

past injustices."

Once ratified, the proposed Final

Agreement will provide full settle-

ment for litigation against the

Province and BC Hydro relate d to

damages created from W.A.C.

Bennett Dam and Williston Reservoir

more than four decades ago. The

creation of the reser v oir led to

severe flood ing in the Peace River

Valley area and forced the Tsay Keh

Dene to move to anothe r location

within their traditional territory.

"BC Hydro acknowledges that mis-

takes were made in the past and we

hope that initializing this agreement

marks a new beginning. By working

together with Tsay Keh Dene, we can

start to build a better future for the

next generations with greater eco-

nomic and social development oppor-

tunities for the First Nation," said BC

Hydro president and CEO Bob Elton.

The agreement will provide a one-

time payment of $26.5M and settle-

ments payments of $2M annually,

recognizing the permanent i mpacts

of the reservoir on the Tsay Keh

Dene's community.

"We have borne a substantial

burden in the name of progress," said

Tsay Keh Dene Chief Ella Pierre.

"Finalization of negotiations on this

agreement provides our community

with a rare, indeed historic, opportu-

nity to take the initiative on a way for-

ward for our people – both current and

future generations."

The Province, BC Hydro and Tsay

Keh Dene have been negotiating a final

agreement since December 2006,

when an Agreement in Principle was

signed. A ratification vote is tentative-

ly scheduled by Tsay Keh Dene in late

June 2009. Subject to a positive vote

outcome, the Final Agreement will be

signed by all parties in July.

The Final Agreement with Tsay Keh

Dene foll ows the completion of a

Final Agreement betw een the

Province, BC Hydro and Kwadacha

First Nation, which was signed on 27

November 2008, which also

addressed grievances asso ciated

with the dam and reser voir.

TRUCE HAS BEEN C ALLED

between the US Department of

the Interior (DoI) and the Federal

Energy Regulatory Commission

(FERC) in the struggle for jurisdiction

of “hydrokinetic” offshore energy

developments in the outer continen-

tal shelf.

A deal has been reached by the fed-

eral agencies to avoid 'bureaucratic turf

battles', said DoI Secretary, Ken

Salazar, in a joint statement with FERC.

They said offshore renewable energy

was too important to be slowed.

Previously, in October 2008, after the

ongoing debate over which agency had

authority, FERC claimed jurisdiction over

the territory hydrokinetic projects.

FERC's assertion came in response

to questions raised by the DoI, which

said the Commission only had respon-

sibility for schemes within state waters.

Instead, FERC claimed that on the con-

tinental shelf it is the licensing author-

ity while DoI is the managing agent.

The new settlement recognises that

hydro power is not specifically covered

in the legislative powers granted to DoI

for ener gy developments offshore,

which focus on oil and gas but more

recently renewables, in particular wind.

However, the settlement says DoI

needs to be actively involved, along with

other federal agencies, in permitting

hydrokinetic projects though it is FERC

that has the primary management

responsibility for the licensing process.

In effect, the agencies appear to

have called a halt to the turf war and

have instructed that a Memorandum

of Understanding (MoU) be drawn up

to enable their staff to push ahead

with licensing requirements. The MoU

will describe the process by which per-

mits and licenses related to renewable

energy resources in offshore waters

will be developed

Announcing the agreement, Salazar

said: “I am proud that we have reached

an agreement with the Federal Energy

Regulatory Commission regarding our

respective roles in approving offshore

renewable energy projects. This agree-

ment will help sweep aside red tape so

that our country can capture the great

power of wave, tidal, wind and solar

power off our coasts.”

“FERC is pleased to be working with

the Department of the Interior and

Secretary Salazar on a procedure that

will help get renewable energy projects

off the drawing board and onto the

Outer Continental Shelf,” Acting FERC

Chairman Jon Wellinghoff added.

In Brief

GERMAN UTILITY

EnBW Energie Baden-

Wurttemberg has signed a

Memorandum of

Understanding (MoU)

with Turkish industrial

group Borusan Holding

for a major push into

renewable energy projects.

he parties plan to estab-

lish a joint venture by the

end of April and work to

develop installed generat-

ing capacity of approx

2GW in Turkey. The

initial aim of the JV is to

develop wind and hydro

power plants.

BC HYDRO HAS

awarded a contract to

industrial group ABB to

retrofit its G.M Shrum

plant by 2011. Under the

Can$18M (US$14M)

contract, ABB is to com-

plete the first phase of the

work by August and then

the remainder by 2010

and 2011, respectively.

The company will perform

engineering, supply of

medium voltage and low

voltage switchgear, dry-

type transformer and

cables, and undertake

installation and provide

commissioning services.

A JOINT VENTURE LED

by Andritz Hydro has won

a contract to supply the

electromechanical equip-

ment for the 170MW

Baixo Sabor scheme in

Portugal. The contract

award by Energias de

Portugal (EDP) is worth

approximately Euro111M,

81% of which goes to

Andritz. Its partner in the

joint venture is Portuguese

company Ensulmeci.

Equipment will be supplied

to two pumped storage

plants, each with two

generating units.

TATKRAFT HAS ACQUIR ED A

majority stake in Turkish hydro

power company Yesil Enerji,

which has a developing por tfolio of

seven projects with potentia l for

633MW of total installed capacity,

and has also taken an equity stake in

tidal current energy developer Atlantis

Resources Corp, which is based in

Singapore.

The Norwegian electricity utility

anticipates closure of the Yesil Enerji

transaction by mid-year, subject to con-

ditions and approvals, which would

give it 95% ownership of the company.

Yesil Enerji is owned by Turkish

diversified industrial group Global

Investment Holdings.

Statkraft said the total budget for

development and construction of Yesil

Enerji's seven projects is in the range

Euro600M-Euro700M (US$813M-

US$949M). In total, the portfolio is

expected to generate approximately

2100GWh of electricity per year.

Yesil Enerji has a 20MW plant under

construction, which is due to be com-

missioned later this year. The other

projects are not due to commence

development until at least next year,

commented Statkraft, however four

have generation licences and the

others have applied for them.

The generation licences ar e

awarde d by the countr y's Energy

Statkraft buys stake in Yesil

Enerji and Atlantis Resources

Management Regulatory Authority.

Meanwhile, Statkraft’s stake in

Atlantis Re source s Corp give s it

exclusive negotiat ion rights for

involvement in projects of f the coasts

of the UK or Canada.

The utility has invested Nkr45M

(US$6.7M) in the company, which is

developing its propriet ary “Solon”

deep-water and “Nereus” shallo w-

water turbines for tidal current power

projects.

Atlantis Resources has just com-

pleted a US$14M funding round,

which includes the equity injection

from Statkraft. An existing key share-

holder, and th e financial a dvisor to

the company for the funding round, is

Morgan Stanley.

The company added that the involve-

ment of Statkraft is a significant step

to help deploy its equipment in the

Pentland Firth off the coast of north

Scotland, between the mainland and

the Orkney Islands, where the Atlantic

Ocean and North Sea meet.

Last month, Atlantis Resources con-

cluded trails of new bi-directional

blades on a Solon prototype turbine at

Bell Bay, in Tasmania. The company

completed the main trials of Solon last

year, and expects to launch a 2MW

unit in the middle of this year.

In December 2008, Atlantis

resources signed an MoU with CLP

Group to collaborate in commercial-

scale development of projects across

Asia-Pacific.

The company said the Solon system

is ideally suited to floating arrays in

water depths of more than 40m-50m.

In the tow trials last year off the coast

of Singapore, the 7m wide turbine pro-

duced more than 500kW in a flowrate

of 8 knots, which it said represented a

throat efficiency of more than 50%.

It added that the Nereus trails were

previously completed and that a tur-

bine has been operational and grid-con-

nected near Melbourne for more than

nine months.

Last year, Atlantis Resources said

it was looking to work local ly wit h

Singapore-based mari ne manufac-

turing players to help develop its

equipment.

Atlantis Resources acquired Current

Resources, the tidal energy business

of Morgan Stanley, earlier in 2008.

Statkraft also recently completed a

major asset swap with European utili-

ty E.ON, which increased its hydro

power portfolio yet further – 40 plants

in Sweden (900MW), 11 in Germany

(262MW) and one in the UK (56MW).

The deal also brought the Norwegian

utility five district heating plants, two

gas-fired plants and a 4.17% stake in

E.ON AG. The utility is also active in

Latin America.

Eletrobras issues international

project development list to 2012

RAZILIAN ELECTRICITY UTILITY

Eletrobras has issued a strate-

gic list of major international

projects with combined capacity of

7.5GW it aims to push development

up to 2012, including six in Peru and

one in Argentina.

The company is already studying

the h alf dozen projects in Peru –

Inambari (2000MW), Paquitzapango

(2000MW), Sumabeni (1074MW),

Urubama (940MW), Vizcatan

(750MW) and Cuquipampa (800MW)

schemes.

Eletrobras is also seeking to devel-

op the 2000MW Garabi scheme in

Argentina.

The projects are key element s of

the company's Strategic Action

Programme over 2009-12, which also

includes construction of 11,000km of

transmission lines. Eletrobras esti-

mated the total investment cost to be

approximately R$30.2B (US$13.4B),

most of which it wou ld orga nise

funding though about R$4.2B

(US$1.86B) is to come through part-

nerships, it said.

In the third qu arter last year, the

company confirmed to the Peruvi an

Government that it was looki ng at

possible hydro power projects. At the

time, the company said the projects

included the Inambari and

Paquitzapango schemes which were

then give n with potent ial installed

capacities of 1355MW and 1379MW,

respectively. Inambari was cited with

an investment budget of US$2B and

both plants were being planned to be

operational by 2014.

France's GDF Suez and Peruvian

mining company Buenaventura have

also been looking at potential hydro

power projects.

Also in Q3 last year, Brazil and

Argentina signed an agreem ent to

investigate further development of the

hydro power resources of the Uruguai

river on the border region, especially

the Garabi scheme.

It was agreed that Eletrobras would

co-operate with Argentinan firm

Empr endimientos Energeticos

Binacionales (Ebisa) on the Garab i

project, cited then as potentially have

capacity of 1500MW.

Eletrobras is a state power holding

group with involvement in studies and

shar eholding i n a range of major

regional electricity companies, and it

consequently has involvement in a

wide generation mix.

HE EXECUTIVE BOARD OF THE

World Bank ha s approved a

US$90M loan for the first phase

of the Lake Victoria Environmental

Management Project II (LVEMP II). The

project involves Kenya, Tanzania and

Uganda.

The project aims to strengthen

regional collaboration to reduce envi-

ronmental stress and to improve the

livelihoods of communities living in the

Lake basin. Lake Victoria is the second

largest freshwater body in the world,

and is currently facing several envi-

ronmental stresses, which are

adversely impacting the basin’s

ecosystem, as well as the region’s

economy. Apart from supporting a

wide diversity of flora and fauna, the

Basin also supports a large fishing

industry for export and local con-

sumption, water supply, lake trans-

por tation, and hydro power generation.

The project was lauded by Board

Members as one that served the ripar-

ian countries’ interests of collaborat-

ing in the management of the regional

public goods, and that advanced

efforts for institutional cooperation for

regional integration. The LVEMP II also

demonstrates the East African

World Bank approves loan for Lake

Victoria environmental management

Communities (EAC) Partner States’

commitment to harmonize their nation-

al policies, legislation, and regulatory

standards to ensure sustainable man-

agement of Lake Victoria’s shared

water and fisheries resources.

The Board also acknowledged the

project’s potential to have a major pos-

itive impact on employment, water

quality, transport, energy and the envi-

ronment in the region.

According to Ladisy Chengula,

Senior Natural Resources

Management Specialist at the Bank’s

Africa Region, this project will help con-

tribute to broad-based poverty allevia-

tion and improvement of livelihoods in

the countries involved: “The success-

ful implementation of this project will

generate a wide range of benefits,

including enhancing the basin’s eco-

nomic growth, reducing poverty to

riparian communities, fostering region-

al cooperation, and protecting the

integrity of a delicate Basin ecosys-

tem.”

About 35 million people, which is

roughly 35% of the total population of

Kenya, Tanzania and Uganda, live in

the Lake Victoria basin.

The regional project is intended to

scale up successful interventions pilot-

ed under the IDA/GEF financed Lake

Victoria Environmental Management

Project I (LVEMP I), which was imple-

mented from March 1997 – December

2005. The LVEMP II has aggressively

sought to incorporate lessons learnt

from the implementation of LVEMP I

into its design. The project will be

implemented in three phases, with

Burundi and Rwanda coming onboard

during the second phase, after meet-

ing certain requirements.

Phase 1 of the LVEMP II program

consists of four main components: i)

strengthening institutional capacity for

managing shared water and fisheries

resources; ii) pollution control and pre-

vention, which aims to reduce envi-

ronmental stresses within the lake; iii)

watershed management which seeks

to reduce environmental stresses from

the lake basin; and iv) project coordi-

nation and management, which will

provide resources necessary for the

effective project monitoring and evalu-

ation activities, and sharing of infor-

mation among countries.

The project is co-financed by the

Swedish Government and the Global

Environment Facility.

HE EUROPEAN BANK FO R

Reconstruction and Deve lop-

ment (EBRD) has agreed a new

loan of €15M (US$20.2M) for

Bulgaria’s UniCredit Bulban k for on-

lending t o private industrial comp a-

nies in Bulgaria to finance energy

efficiency and small renewable energy

projects.

The loan is par t of the second exten-

sion of the Bulgarian Energy Efficiency

and Renewable Energy Credit Line

Framework to provide up to €55M

(US$74.2M) in credits to banks

involved in lending for energy efficien-

cy and renewable energy projects.

The programme is complemented

by grant funding from the Kozloduy

International Decommissioning and

Support Fund, which will be used for

technical assistance to support proj-

ect preparation and awareness raising

activities, and for incentives to com-

panies and banks that successfully

implement projects.

These incentives will be based on

the estimated level of energy savings

or annual production of clean energy

derived from renewable sources.

Reducing energy intensity is one of

the main priorities of Bulgaria’s energy

policy, together with ensuring the secu-

rity of supply and the sustainable

development of the energy sector.

In this context, Bulgaria has already

set a national target for energy savings

of no less than 9% of domestic energy

consumption over a period of nine

years up until 2016.

Signing the project, EBRD President

Thomas Mirow said that this credit line

is an important element of the

Sustainable Energy Action Plan signed

today with the government of Bulgaria.

“It will further increase investments in

energy efficiency and renewable

energy at a time when market condi-

tions remain difficult,” he said.

“With the funds from this credit line

UniCredit Bulbank aims to encourage

and support the energy responsible

attitude and will promote the energy

production from renewable energy

sources, which has a lot of environ-

mental and economic advantages”,

added Levon Hampartzoumian, Chief

Executive Officer of UniCredit Bulbank.

The EBRD is one of the largest

investors in Bulgaria with some €1.7B

(US$2.3B) committed to projects

across the country. Working with its

many partners, the Bank has

mobilised more than €6.2B (US$8.4B)

for projects in Bulgaria.

UniCredit Bulbank, member of the

European UniCredit Group, is the

biggest Bulgarian bank with assets of

above BGN 11B. The bank serves over

one million active clients through one

of the widest banking networks in

Bulgaria with more than 260 branches

and offices in the country.

Over the last few years the EBRD

played a significant role in supporting

Bulgaria’s efforts to reduce energy

intensity and has developed targeted

financial instruments to accelerate

transition to a low-carbon economy.

Reservoir Capital in JV to

push Serbia projects

A JOINT VENTURE has been formed in principle between Reservoir

Capital and Global EcoPower to develop two run-of-river plants in Serbia,

licences for which were granted last month.

Reser voir Capital and Global EcoPopwer plan to set up the JV as a

development company to undertake the Brodarevo 1 & 2 projects and

also both buy and build other hydro power schemes in Serbia and the

Balkans region.

Global EcoPower is a French renewables energy developer, and the JV

gives it the potential to acquire an equal equity stake in the Canadian

firm's subsidiary Renewable Energy Ventures by funding the Brodarevo

projects to the bankable feasibility stage. The company is also to

arrange the necessary debt funding for the projects.

The Brodarevo plants are to be built on the river Lim in south-west

Serbia and have combined installed capacity of 48MW. The river already

has four run-of-river plants.

The partners aim to develop up to 700MW of renewables capacity in the

Balkans region by 2015.

HE DRAFT ENVIRONMENTAL

Impact Statement (EIS) for the

reli censing application of th e

831MW Catawba-Wateree scheme, in

Nor th Carolina and South Carolina,

has been prepared by the staff of the

US Federal Energy Regulatory

Commission (FERC).

Deadline for comment on the draft

EIS is 8 May. The final EIS is expected

to be issued in November.

The scheme is located over the

Catawba and Wateree river catch-

ments, and comprises 11 reservoirs

and 13 developments. At present, it is

being operated under an annual

licence following expiration of the pre-

vious main licence in August last year.

Duke submitted the application in

August 2006, and a revised compre-

hensive relicensing agreement in

December that year that included envi-

BERDROLA HAS BEEN AWARDED A

five-year contract by Energias de

Por tugal (EDP) to m anage the

Aguieira and Raiva plants and market

the hydroelectric output.

The contract commences on 1 April

and expires on 31 March 2014.

The plants in the Mondego river

basin have combined installed capac-

ity of 360MW, including 270MW of

reversible pump capacity at the

336MW Aguieira facility. Raiva has an

installed capacity of 24MW.

Iberdrola sees the contract as a fur-

ther step in its participation in the

OITH HYDRO HAS WON A

contract from American

Municipal P ower-Ohi o (AMP -

Ohio) to supply equipment to the

Captain Meldahl project.

AMP-Ohio awarded the US$122.9M

contract for turbines and generators for

the new 105MW plant being built near

Hamilton on the Ohio river. The com-

pany will be a co-licensee with

Hamilton, and is to be entitled to 51%

of the hydroelectric output.

The project is part of AMP-Ohio's

plan to increase the hydro power

assets in its portfolio by a total of

380MW.

Last year AMP-Ohio and Voith

announced a contract to provide tur-

bines and generators for the

Smithland, Cannelton and Willow

Island projects on the same river. AMP-

Ohio is awaiting final permits from the

REVALI RENEWABLE ENERGY,

Inc, has been established by

Canada- based mining firm

Trevali Re sources Corp, and its first

action has bee n to agree d ebt fund-

ing for the acquisition and upgrade of

a mini-hydro plant in Peru.

The new company has agreed to a

debt finance arrangement with two local

Peruvian banks to help buy and upgrade

the Tingo run-of-river hydro plant from

1.2MW to 8.8MW. Trevali wants to link

the plant to he national grid.

The Peruvian banks are Banco

Internaciona l del Peru and Estudio

Echecopar. They are to jointly arrange

FERC staff issue draft

EIS for Catawba-Wateree

ronmental improvements for flow

rates, water quality, habitats for endan-

gered species, and also recreation.

Then, in March 2007 - shortly after the

public scoping process began - a sup-

plement and clarification to the appli-

cation was submitted.

No changes to installed capacity

have been sought in the application.

In reviewing the application, FERC

staff have produced their own alterna-

tive to the Duke proposal for relicens-

ing, which adds to the utility's plans

various actions, such as: installation

of a bladder dam to Wateree dam to

help flood management; wider agency

consultation in low flow conditions;

implementation of flow ramping when

increasing or decreasing releases for

recreation; a number of additions to

plant and wildlife measures; and

revised public safety plans.

Voith wins further

contract from AMP-Ohio

US Army Corps of Engineers (USACE)

to start building the four projects.

Another two projects are being

planned – the R.C. Byrd Locks and

Dam on the Ohio river, and Bluestone

on the New river in West Virginia.

In the 1990s, the company built the

42MW Belleville plant, which is owned

by a number of communities. AMP-

Ohio operates the plant. Separately,

the town of Hamilton owns and oper-

ates the 72MW Greenup plant, also on

the Ohio river and built in 1982.

Voith Siemens Hydro Power

Generation, a joint venture between

Voith and Siemens, changed its name

to Voith Hydro on 1 April. The JV was

established in 2000 to market turbines

and generators.

Onwership balance of the company,

which is majority (65%) held by Voith,

will remain the same.

Trevali sets up renewables

unit, agrees Tingo funds

long-term credit facilities to cover all

the US$20M debt finance needs of

the project.

The plant and water rights are cur-

rently held by Compania de Minerales

Santander, which is majority owned by

Trevali.

The hydro plant would help power a

re-opened mining operation at

Santander, some 215km from Lima.

Tingo is approximately 17km from the

main mine infrastructure, which ended

production in 1993.

The new mining plan and hydro proj-

ect results from Trevali's successful

exploration work in the area in late 2007.

Pile barrier prep for Wolf Creek

Technical assistance for the secant

barrier will have an average depth of

83.8m (275ft), and reinforces a previ-

ous concrete structure completed in

the early 1970s.

The four-year project was awarded

as a US$341.4M contract to the JV in

July last year by the US Army Corps of

Alto Tamega project in northern

Portugal.

The Alto Tamega scheme calls for

four dams (Gouvaes, Padroselos, Alto

Tamega and Daivoes), four power

plants, approximately Euro 1.7B

(US$2.3B) of investment and is to be

completed by 2018.

The plants will comprise two pump

turbine facilities with total capacity of

900MW, and two conventional gener-

ation plants with 234MW of total

capacity.
