HE PEOPLE'S REPUBLIC OF

China's (PRC) push to make its

energy sector cleaner and more

efficient is to receive increased sup-

por t f rom the Asi an Development

Bank (ADB).

ADB will provide three technical

assistance grants totalling US$2.8M

to support government initiatives to

reduce sulfur dioxide gas emissions,

increase energy savings, and

ADB loan to help strengthen

China's energy sector

strengthen a fund that supports clean

energy projects.

Over the past two decades the

PRC's economy has grown at an aver-

age rate of over 9.5% a year. But the

heavy reliance on coal for the bulk of

its surging energy needs has resulted

in harmful levels of sulfur dioxide and

other air pollutants that are the primary

cause of acid rain.

“PRC is confronted with serious envi-

ronmental challenges that not only

affect domestic production, but also

have significant links with climate

change,” said Anil Ter way, Director,

Energy Division of ADB's East Asia

Department.

To support the government's target

of cutting sulfur dioxide emissions by

10% between 2006 and 2010, an ADB

technical assistance grant of

$500,000 will be used to design and

implement a national emissions trad-

ing system. This will provide a financial

incentive to companies to curb emis-

sions and complement other govern-

ment measures to reduce air pollu-

tion. It follows ADB backing of a pilot

sulfur dioxide trading scheme in

Taiyuan City in 2004.

ADB will al so provide technical

assistance totalling $1.5M to sup-

port the government's goal of

making energ y savings of 20% by

010. It will be used to look at steps

needed to attract international finan-

cial institutions to invest i n energy

efficiency and conservation projects.

Presently, provincial governments in

the PRC lack the capacity to readily

initiate energy projects that could

potentially tap external financing.

The technical assistance will also

help improve t he scheduling of

power generation by giving higher pri-

ority to zero- and low-carbon dioxide

emitting power plants.

The PRC's China Clean

Development Mechanism Fund –

designed to encourage clean energy

projects that generate certified emis-

sions reductions (CERs) that can then

be sold to developed countries that

need them – is also getting ADB policy

and advisory assistance worth

$800,000. It will be used to build up

the capacity of the Fund for promoting

and supporting climate change-relat-

ed projects. The PRC is estimated to

have the potential to generate about

50% of total worldwide annual CERs

under the Clean Development

Mechanism established in the Kyoto

Protocol.

The financial support is in the form

of grants with $1.4M coming from

ADB's regular technical assistance

funding program and $1.4M from its

Climate Change Fund.

This Fund was established in May

2008 to help developing member

countries put in place projects that

mitig ate the adverse impacts of cli-

mate change and bols ter e nergy

security.

Endesa Chile ends suit over water regulation

LECTRIC POWER UTILITY

Endesa Chile has ended its suit

over restrictions on how it is

allowed to be i nvolved in regulatio n

of water use for hydro power.

Progress with various parties, such

as those involved with irrigation i n

river basins in Chile, has led the util-

ity to drop the suit ag ainst the

Treasury dept.

Endesa Chile said some agree-

ments have been reached that will

enable it to become involved in future

in some regulatory committees. It

added that its collaborative approach

has received cooperation from the

general waters authority DGA

(Direccion General de Aguas) and the

hydraulic works authority (Direccion de

Obras Hidraulicas).

The suit agains t the Government

w as brought just over a year ago

a nd both parties have agreed to

its termination.

More than 70% of the utility's

almost 4.8GW installed generating

capacity in Chile is hydro power. Key

plants are: Ralco (690MW);

Pehuenche (570MW); Pangue

(467MW); El Toro (450MW); Rapel

(377MW); Anluco (320MW); Abanico

(136MW); Curillinque (89MW); Sauzal

(76.8MW) and Isla (68MW). The

Palmucho plant (32MW) was commis-

sioned just over a year ago.

Better hydrology in Chile in 2008

helped to offset the effects of higher

fuel costs elsewhere in the utility's

generation portfolio.

In total, including assets in other

Latin American countries, it has

installed capacity of 12.7GW.

A key foreign asset is El Chocon

scheme (1320MW) in Argentina, which

comprises El Chocon (1200MW) and

Arroyito (120MW). In 2008, the utility

experienced weaker hydrology in the El

Chocon area.

In Colombia, the utility's prime hydro

assets are Guavio (1163MW), Betania

(540.9MW), Guaca (324.6MW) and

Paraiso (276.6MW).

The key asset in Brazil is the

Cachoeira Dourada plant (665MW) in

Goias, which is held by Endesa Brasil.

Endesa Chile's main hydro assets

in Peru are Huinco (247MW), Chimay

(151MW), Matucana (128MW),

Callahuanca (80MW) and Moyopampa

(65MW).

Brazil hydro aces gas; funding for Santo Antonio

N HYDRO DEVELOPMENT IN BRAZIL

the country has seen such high levels

of precipitation recently that it is look-

ing at a strategic cutback in imported

natural gas, and project development

has also seen major funds provided for

one of the largest schemes of recent

years – Santo Antonio.

The Ministry of Mines and Energy

(MME) said that the current high stor-

age levels in reservoirs had given

security of energy supply in the cur-

rent season, and so presented an

opportunity for a reduction of gas

imports.

Rainfall in December and January

was much higher than average, and

the trend is expected to continue this

month.

Based on the good hydrological

conditions, the Electricity Sector

Monitoring Committee (CMSE) had

decided to review the imports of gas,

said MME.

In a further major step forward for

hydro power in the country, Brazil's

national development bank, BNDES,

has approved R$6,100M

(US$2,575M) of funds to help the

concessionaire build the 3150MW

Santo Antonio project. The financing

equates to 46.6% of the project

budget, and, when combined with

funds from other financial organisa-

tions, brings the total debt to almost

two-thirds of the budget.

The concession was won by

Madeira Energia SA (Mesa), a consor-

tium led by Furnas and Odebrecht and

including Andrade Gutierrez, Cemig

and a private equity fund held by

Santander and Banif.

BNDES is providing the funds to

Santo Antonio Energia (SAESA), which

is a wholly-owned subsidiary of Mesa.

Mesa has contracted Consorcio

Construtor Santo Antonio (CCSA) to

build the project, with the first of 44

generation units expected to be com-

missioned by May 2012. The JV

includes Odebrecht, Andrade

Gutierrez, Alstom Hydro Energia

Brasil, Areva Transmissao and

Distribuicao de Energia, Siemens,

Andritz Hydro, Voit h Siemens and

Bardella.

Santo Antonio is one of two projects

in the 6450MW Madeira scheme. Its

sister project is the 3300MW Jirau

scheme.

In Brief

IBERDROLA IS

preparing to build the Alto

Tamega scheme in

Portugal which will call

for Euro 1.7B (US$2.24B)

of investment. The

scheme, to be completed

by 2018, calls for the

construction of four dams

–

Gouvaes, Padroselos,

Alto Tamega and Daivoes.

Four power plants will

also be built – two pump

turbine facilities with total

capacity of 900MW, and

two conventional genera-

tion plants with 234MW.

CAVICO HAS BEEN

awarded a tunnelling

contract valued at

US$9.8M on the 37W

Song Giang 2 project in

Vietnam. The Vietnamese

contractor's subsidiary

Cavico Hydropower

Construction is to con-

struct a 3.9km long

headrace tunnel, two sub

tunnels of 650m in total

length, and a 42m high

surge tank. Site prepara-

tion work begins during

the first quarter of the

year, and the contract

period is 20 months.

OCEAN POWER

Technologies (OPT) and

Lockheed Martin have

signed a Letter of Intent

(LoI) to collaborate on a

utility-scale project using

OPT's proprietary system

PowerBuoy. No details

were available to quantify

the scale of the proposed

Russia, Georgia in pact for Inguri ops

MEMORANDUM OF UNDER-

standing (MoU) has been

signed between Russia's Inter

RAO and the Government of Georgia

to help improve the efficient operation

of the 1.3GW Inguri hydro power plant.

The MoU proposes a 10-year pro-

gramme of measures to improve the

efficiency of Inguri's plant, dam and

reservoir, which are spread across the

border between Georgia and Abkhazia.

Abkahzia declared its independence

of Georgia a decade ago. Russia last

year formally recognised Abkhazia as

independent of Georgia, following the

conflict between the countries over

another region, South Ossetia.

Inter RAO said that talks with lead-

ers of power sectors in Georgia and

Abkhazia had taken place in prepara-

tion for the pact.

The plant is a major power facility in

the region. It is located on the Inguri

river and includes a 271.5m high

double curvature arch dam with a

crest length of 680m. The project was

completed in 1980 with an initial

installed capacity of 400MW. It now

generates approximately 4500GWh of

electricity per year.

In the late 1990s work was

launched to improve safety of the dam,

supported by funding from the

European Bank for Reconstruction and

Development (EBRD). The dam is

founded on complex geology, princi-

pally comprising limestone and

dolomite, and there are tectonic cracks

and fractures in the area.

Severn tidal shortlist down to five options

HE UK GOVERNMENT HAS

announced a proposed shortlist

of five project options to exploit

tidal energy in the Severn Estuary in

southwest England. A feasibility study

of 10 project options lasted about a

year before the proposed five short-

listed alternatives were chosen:

• Cardiff Weston Barrage (8.6GW,

costing £19.6B-£22.2B (US$27.6B-

US$31.2B));

• Bridgwater bay Lagoon (1.36GW,

generating 2.6TWh/year and costing

£3.4B-£4.1B (US$4.8B-US$5.75B));

• Fleming Lagoon (1.36GW, generating

2.3TWh/year and costing £4.1B-£4.9B

(US$5.75B-US$6.9B));

• Shoots Barrage (1.05GW, generating

2.7TWh/year); and,

• Beachley Barrage (625MW, generat-

ing 1.6TWh/year and costing £2.1B-

£2.5B (US$3B-US$3.5B)).

The Depar tment of Energy and

C limate Change (DECC) has

launched a three-month public con-

sultation on all 10 projects and its

proposed shortlist. The consultation

ends 23 April. Following analysis,

a final shor tlist will be issued to

go for ward to the next stage of

study, which will be fo llowed by a

further public consultation.

DECC said a final decision on the

tidal power exploitation at the Severn

is to be made next year.

The DECC also announced £0.5M

(US$0.7M) to fund development work

on technologies such as tidal reefs

and fences.

RAN EXPECTS TO HAVE FIVE

large dams comp leted by its

year end, in late March, out of

the total of 94 major projects under

construction.

The country has had lower rainfall

in many areas and is pushing ahead

with its da m b uilding programme

despite limited materials supplies

over the past year. Limited funding

was also an issue and the

Government has incr eased credits to

the water sector, said the Ministry of

Energy and Water Affairs.

Iran dam building pushing ahead

TATKRAFT HAS CLAIMED THE

European renewables crown fol-

lowing the completion of its

asset swap with E.ON. The assets

were legally transferred at the end of

December with the total value of the

swap almost Euro4.5B (US$5.95B).

Under the deal a lar ge number of

hydro power plants were transferred to

Statkraft. The transfer included 40

plants in Sweden (900MW), 11 in

Germany (262MW) and one in the UK

(56MW).

To implement the Khoda-Afarin and

Qiz Qalasi hydro power plants the

Government has given Euro 85M

(US$109.9M) and Euro 40M

(US$51.7M), respectively, it was sep-

arately reported by Mehr News Agency.

The agency added that the 78m

high Alborz embankment dam, in

Mazandaran province, is due to be

completed by mid-2009. The dam is

being built by Mazanaran Regional

Water Co, which is also constructing

the Galvard dam and that project is

just over a quarter completed.

Half a year ago the Ministry gave the

total number of dams at about 90, and

in late 2007 it noted that the country

had 176 potential large projects.

In reviewing the number of projects

built, the Ministry said Iran had

14 dams built betwe en the 1950s

and 1979, and since then

appr oximately 500 structures (180

large and 320 small).

The Ministry added that the Iranian

dams sector is also involved in imple-

menting water-related projects in a

dozen other countries.

European renewable crown for

Statkraft on asset swap completion

The deal also brought the

Norwegian utility five district heating

plants, two gas-fired plants and a

4.17% stake in E.ON AG.

In return, Statkraft gave its 44.6%

stake in E.ON Sverige plus a hydro

power plant. The deal gives E.ON full

ownership of E.ON Sverige.

The deal was announced in late

2007 and developed over a number of

months to be finalised later than

expected, in mid-2008, before being

completed in December. It makes

Statkraft the largest generator of

renewable energy in Europe.

In other news, Statkraft also

announced it has opened a mini-

hydro plant at Rodberg to fur ther

exploit cascade potential and has

approval to b uild the Eiriksdal sta-

tion. The 2.9MW Rodber g plant has

been built between the Nore 1 and

Nore 2 plants, and generates electric-

ity using the minimum releases from

the Rodberg dam. It is expected to gen-

erate an average of 15.5GWh per year.

IVERBANK POWER CORP HAS

received the greenlight to begin

studies for a 1GW underground

pumped storage plant in the US state

of New Jersey.

The US independent power pro-

Sparta, NJ, to study the use of the

Limecrest Quarry and bedrock below

to form the upper and lower reser-

voirs of a “closed-loop” pumped stor-

age system.

Riverbank Power gets OK to study

1GW buried pumped storage plant

Riverbank Power is about to begin a

detailed site investigation study and

formal environmental assessment of

the plans for the site. The lower reser-

voir would be approximately 610m

below the flooded quarry.

With permissions and approvals, it

aims to invest US$2B and expects the

construction phase would take four

years, completing by 2015.

The company, backed by venture

investor Blackrock, aims to build at

least five closed-loop pumped storage

plants, each with installed capacity of

1GW, in North America. The system

design is branded “Aquabank”.

Developing major peak power plants

are important to help grid stability

HE AFRICAN DEVELO PMENT

Bank (AfDB) has approved

financing of US$ 16.4M to

improve electricity supply in Lesotho,

including the restoration of a 2MW

hydro scheme and development of

further small hydro schemes.

The Board of Directors of the AfDB

approved a combined loan and a grant

of 11 million Units of Account, (UA)

equivalent to US$16.4M, to finance

the country’s Electricity Supply Project.

The UA 8.9M loan and UA 2.1M grant

will support investment in electricity

supply infrastructure to enhance elec-

tricity access rate and ensure

improved efficiency, reduce shortages

and assist the country to reduce pover-

ty and achieve the Millennium

Development Goals (MDGs).

The project is consistent with the

implementation framework of the

African Development Fund, which

focuses on investment in infrastruc-

ture, governance and regional integra-

tion, vital for the development of

markets to support growth. On com-

AfDB approves US$16M to improve

electricity supply in Lesotho

pletion, it is expected to improve living

conditions for the population and con-

tribute to poverty reduction and eco-

nomic growth by providing expanded,

sustainable electric power at afford-

able cost, using renewable energy

resources.

Under the project, electricity pro-

duction shortages will be alleviated by

exploiting renewable energy sources

such as hydro power and energy con-

servation and demand management.

The project envisages restoration of

the 2 MW hydro plant to make up for

production shortages by 17MW which

is quite significant for Lesotho. The low

electricity access rate will be

addressed through the expansion of

the transformation and distribution

system in Maseru, Hlotse, Mphaki and

Mantšonyane, in keeping with the

country’s 2007 Rural Electrification

Master Plan as well as its 2020 Vision.

The project is in line with the areas

of focus and strategic intervention pil-

lars of the Poverty Reduction and

Growth Strategy (PRGS) and Country

Strategy Paper (CSP) for Lesotho

(2008-12), which are, in turn, derived

from the Vision 2020. Improved energy

infrastructure will bolster private sector-

led economic growth envisaged for the

mining, manufacturing, textile and

tourism sectors.

The project also conforms worth the

Bank’s Clean Energy Investment

Framework (CEIF) approved by the

oard in March 2008, which focuses

on promoting clean energy develop-

ment and contributing to global emis-

sions reduction efforts, by steadily

raising energy efficiency on the supply

side and encouraging a culture of

energy saving on the demand side,

increasing the contribution of renew-

able energy sources, and paying close

attention to environmental and social

externalities of energy production.

The total project cost is estimated

at UA 15.18M. The AfDB loan

accounts for 72.48 % of the costs. The

remaining 27.52% will be financed by

the government and the Lesotho

Electricity Corporation (LEC).

ENERGY POWER PLC HAS BEEN

commissioned by RWE Power to

evaluate the potential increase

in output that could be achieved from

RWE’s existing run-of-riv er hyd ro

The results of the study will then be

used as the basis for estimating how

superconducting variable speed gen-

erators could contribute to increases

in efficiency and output of a further

eight similar hydro sites operated by

RWE along the river Mosel. The results

of which are expected later this year.

In total, RWE operates ten run-of-

river hydro plants on the river Mosel

which together generate over 800GWh

of electrical power every year. Once

received and evaluated, the data from

the Group’s study will be used by RWE

to compile an economic evaluation of

the business case for replacing con-

ventional generators in run-of-river

hydro plants with generators based on

superconductor components.

Tenders

AN INVITATION TO

tender has been issued for

the supply and installation

of control, protection

and monitoring equipment

to the Dokan and

Derbandikhan hydro

power projects in Iraq. The

work is part of a rehabilita-

ion scheme being carried

out at the two plants and is

part funded by a credit

bids is 1 April 2009.

The 400MW Dokan and

249MW Derbandikhan

schemes are the largest

power plants in the

Kurdistan Region of the

country, and both are

connected to the National

Grid. Each plant is part

of a multipurpose scheme

for power production

and irrigation.

The scope of work on

both schemes includes the

design, manufacture,

factory testing, delivery,

civil works, installation,

training, site testing and

commissioning of the

IADB agrees loan to help

manage Caroni catchment

YDRO GREEN ENERGY (HGE)

has installed the first com-

mercial hydrokinetic turbine,

and the second unit is to be placed

around April at the site n ear

Hastings, Minnesota.

First power is expected to be avail-

able from the project's initial unit this

month. The project only won approval

of the US Federal Energy Regulatory

Commission (FERC) in December.

The units will be attached to a

floating barge in the tail race of the

US Army Corps of Engineers' Lock &

Dam No2 on the Mississippi river.

USACE approved t he project in

November. Each unit has a capacity

of 35kW, said FERC, and HGE noted

they nameplate capacities of 100kW.

FERC h as said the project is

important as it comb ines new

technology with a conventional

hydro power dam. USACE's existing

plant at Lock & Da m No2 h as an

installed capacity of 4.4MW.

AVEGEN AND NPOWER HAVE

received consent for the

Siadar wave energy p roject

in Scotland using o scillating water

column technology (OWC).

Approval for the 4MW project, to be

located on the island of Lewis, was

given by the Scottish Government.

The plant will be constructed of a

250m long breakwater and 40 x

100kW turbines. Using Wells turbines,

the plant is to be commissioned by

late 2010.

WaveGen is a subsidiary of Voith

HE INTER-AMERICAN

Development Bank (IADB) has

agreed to give Venezuela a loan

to help improve the management of

the catc hment area of the Caroni

river, including enhancing hydroelec-

tric potential.

A US$14M loan has been agreed by

the bank to help the Ministry of

Popular Power for the Environment to

sustainably manage the watershed.

The bank said that the long-term

objective of the programme is to

enhance the hydroelectric potential of

the Caroni catchment.

It said that goal could be achieved

by encouraging the sustainable and

integrated management of local

resources.

The Ministry is to use the funds pri-

marily for institutional strengthening of

those organisations in charge of the

management and development of the

Caroni catchment.

Key aspects of the work also include

protecting land rights, promoting appro-

priate land use practices and improv-

ing living conditions for local

communities, including indigenous

peoples.

Venezuela is rich in hydro power

potential and under construction at

present on the Caroni is the Manuel

Piar Tocoma scheme, which will have

an installed capacity of 2330MW and

is to be completed by 2012. The client

is state-owned utility CVG

Electrificacion del Caroni (Edelca).

Almost two years ago the Andean

Development Corp (CAF) agreed to

loan US$600M over 18 years to help

build the scheme.

Wavegen, npower gets

approval for Siadar project

Siemens Hydro Power Generation,

being a member of the group's Ocean

Energy division. RWE Innogy owns the

utility npower.

The scheme would be eligible to

receive revenue support via the

Government's Renewable Obligation

scheme.

The companies have been working

on the project together since 2006.

Wavegen has a grid-connected 500kW

test plant for the technology on the

island of Islay, and it began operations

in 2000.

Renewables global agency

IRENA launched

THE INTERNATIONAL RENEWABLE Energy Agency (IRENA) has been

launched today at the beginning of a two-day establishing conference in

Bonn, Germany.

An initiative spearheaded by Germany, with support from Denmark and

Spain, the agency has had dozens of countries signed up so far.

The agency is argued to be a key step in helping to address climate

change, which supporters said will help parties to take informed decisions

and use renewable energies in cost effective ways.

Supporters aim to make the agency the main driving force to pr omote

rapid transition to widespread and sustainable use of renewable energy on

a global scale. It is envisaged by them that the agency will act as the

'global voice' for renewable energies and facilitate access to all relevant

information, including data, best practices, effective financial mecha-

nisms, and technological expertise.

Pre-launch activities included a side event at the UN Climate Change

Conference (COP14) last month, which followed significant development

activities throughout 2008.

CONTRACT TO EQUIP THREE

hydro power plants in Turk ey

has been awarded to a joint ven-

ture of Alstom Hydro and GES by

turbines, generators and other equip-

ment required for the Turkish-Austrian

developer's three plants, which have a

combined installed capacity of 417MW.

Alstom will design, supply, trans-

port, supervise and commission the

seven vertical Francis turbines and

generators to be supplied to the three

plants – Kavsakbendi, Kopru and

Menge – which are to be commis-

sioned over 2010-11. The equipment

value is approx. 70% of the contract.

Kavsakbendi will have an installed

capacity of 183MW (3 x 61MW) and

the generators are rated at 66MVA.

The Kopru plant will have an

installed capacity of 148MW (2 x

74MW) with generators of 80MVA.
