HE NUMBER OF LICENCES
i s s u e d f o r s m a l l h y d r o
power schemes by the UK’s
Environment Agency has increased
substantially in the last decade, the
government agency has announced,
with the number of new schemes
in the country expected to treble
by 2020.
At the Chartered Institution of Water
and Environmental Management
(CIWEM) National Hydropower con-
ference held yesterday, EA chairman
Lord Chris Smith said that 31 licenc-
es for hydro schemes were issued
last year, compared to only five
in 2000. This year the agency has
already granted licences for 31 new
schemes, with a further 166 applica-
tions under consideration.
Currently, there are approximately
400 hydro schemes in England and
Wales, and Lord Smith explained
this number is expected to rise to
1200 by 2020.
In March this year, the EA released
the Hydropower Opportunities and
Environmental Sensitivities Map
which identied almost 26,000 new
locations where small scale hydro
power could be deployed in England
and Wales. Together, these sites
could generate enough electricity to
power up to around 850,000 homes
and produce 3% of the country’s
2020 renewable electricity needs. In
reality, however, only some of these
sites could be exploited due to envi-
ronmental sensitivities, as well as
practical constraints such as access
to the electricity network.
The new maps help to identify
areas where hydro power could make
a positive contribution to the local
environment, and sites where it is
less appropriate.
The report found that a sensitively
designed hydropower scheme that
includes a sh pass could improve
the local environment as well as gen-
erate electricity in over 4000 sites.
These opportunities are particularly
concentrated on rivers such as the
Severn, Thames, Aire and Neath.
With the government soon to
offer subsidies of up to 20p for
every kilowatt hour of electricity pro-
duced, a medium-sized scheme that
typically generates enough electricity
for about 32 homes, could receive
around £25,000 a year. Average
set up costs range from £100,000
to £150,000. But, the Environment
Agency stressed, only schemes that
were well designed and had no nega-
tive impacts on the river wildlife or
the local environment would get the
go ahead.
“Some hydro power schemes have
the potential to deliver low carbon
electricity and improve the local
environment for wildlife, for exam-
ple by improving sh migration. But
there will inevitably be some sites
where the risk to the environment
outweighs the benets of power gen-
eration,” said Tony Grayling, Head
of Climate Change and Sustainable
Development at the Environment
Agency. “With Government’s new
feed-in tariff for renewably generated
electricity, hydropower could become
an attractive income generator for
hydro power developers, if environ-
mental safeguards are met.
“The report recommends that
fish-friendly design needs to be
incorporated in all schemes, and
that grants for sh passes could
help to unlock the potential of
small scale hydro power in England
and Wales.”
UK sees surge in hydro development
Studies shortlist new dam sites in New Zealand
S
EVERAL SITES HAVE BEEN
identied as potential locations
for water storage dams on the
Ruataniwha Plains in New Zealand
following initial geological studies in
the region.
A report on the geological stud-
ies has assisted both Hawke’s Bay
Regional Council and the Ruataniwha
Water Storage Dam Leadership to
assess the viability of several sites.
During the prefeasibility process the
Regional Council started with an ini-
tial list of 30 potential sites. This was
then worked through and narrowed
down to 14 sites of which six were
considered most likely.
These original 14 shortlisted sites
have had on-ground, physical geologi-
cal/seismic assessments over the
last two months. Of these, ve are
now considered unsuitable because
of ground condition risks. Some of the
remaining set of sites are looking very
positive but further assessment work
is still underway. Relevant landowners
in these areas are being contacted by
Hawke’s Bay Regional Council and
informed as sites are removed off
the list.
“This is a completely normal part of
the process to assess potential dam
sites. It’s a complex project and our
feasibility study as much about exclud-
ing sites that have risks as including
sites needing further investigation,”
said Bruce Corbett, Group Manager,
Water Initiatives for Hawke’s Bay
Regional Council.
The study report was presented to
the Ruataniwha Water Storage Dam
Leadership group chaired by Sam
Robinson earlier this month. The
group is working with Hawke’s Bay
Regional Council to step through the
feasibility work for the proposed water
storage dams.
The geological studies have shown
that there is ample dam site capacity
in the north of the Ruataniwha Plains
area but in the south there is less avail-
able storage capacity which reduces
options, particularly in Takapau.
The Council will focus further
assessments now on sites where
geological fatal aws are not appar-
ent, and where sufficient and eco-
nomically achievable storage can go
ahead. Fortunately, there is very good
geological data available for the area
which identies a lot of the numerous
fault lines and unsuitable soils.
Eight of the potential sites
now being studied can provide
90-110Mm
3
compared to the maxi-
mum storage requirement of 90Mm
3
to serve the entire area of 22,500
ha. Likely dam positions close to
those originally identied are also
being looked at.
The new and repositioned sites will
reduce pumping requirements as they
are more gravity fed. Two sites also
offer hydro power potential.
GNS seismic studies are currently
underway to confirm the geological
assessments. This will also provide
dam design parameters which will
influence construction costs and
therefore further decisions.
Parallel to this, the Regional
Council’s water project team will be
working with the Ruataniwha Water
Users Group, and will meet with cur-
rent irrigators and major dryland farm-
ers in the irrigation zones to gauge
and prioritise demand for stored
water.
SN Power and IFC in Vietnam power agreement
N
ORWE G I A N RENEWABL E
energy firm SN Power and
the International Finance
Corporation (IFC) have entered into a
Joint Development Agreement (JDA)
that will see them develop sustaina-
ble hydro power projects in Vietnam.
This agreement will enable IFC,
acting through IFC InfraVentures, an
early stage project development fund,
and SN Power to develop an invest-
ment strategy, policy, and guide-
lines to address Vietnam’s growing
demand for power. The partners will
acquire operating assets and invest in
greeneld projects to build up a port-
folio of renewable energy investments
in the country.
The project will be IFC’s first
investment in Vietnam through IFC
InfraVentures, and SN Power’s rst
partnership in Vietnam.
“This IFC partnership will allows
us to find viable hydro power
projects and subsequently develop
and operate them in a sustainable
manner. SN Power has followed the
Vietnamese power market for several
years. We believe we can strengthen
Vietnam’s long-term renewable gen-
erating capacity through our power
market experience and technology
transfer,” said Erik Knive, Executive
Vice President SN Power Southeast
Asia.
SN Power and IFC have collabo-
rated previously on several of SN
Power’s global investments in wind
and hydro power plants in Chile,
India, and the Philippines. SN Power
uses IFC’s social and environmental
performance standards for conduct-
ing due diligence of acquisition and
greeneld power projects.

Nicaragua to boost hydro
N
ICARAGUA’S MINISTRY OF
Energy and Mines (MEM) has
confirmed that hydro gen-
eration activities in the country will
increase signicantly within the next
four to ve years with 18 hydroelectric
projects in the study phase and six
projects currently under construction.
Nicaragua has a hydroelectric
potential of 3280MW, of which only
98MW is currently being utilized. This
represents a huge potential for com-
panies interested in developing hydro-
electric projects in the country, in
addition to the opportunities in other
types of renewable energy sources,
said PRONicaragua, the Nicaraguan
Investment Promotion Agency.
The Tumarin project on the
Grande River in Matagalpa could be
one of the most important projects
in the last 50 years in Nicaragua,
according to representatives of the
National Assembly. It is estimated
to produce 250MW, one third of the
country’s current demand, and will
save up to US$100M in fuel imports
per year.
T
HE WORLD BANK HAS APPROVED
$350M to finance a Dam
Rehabilitation and Improvement
Project which aims to improve the
safety and sustainable performance
of over 220 selected dams in India,
and has also approved a credit worth
US$146M for the second phase of a
project to rehabilitate and modernize
the Jinnah Barrage in Pakistan, and to
improve irrigation and water manage-
ment in the country.
India is home to about 4700 com-
pleted large dams – almost half of
which are more than 25 years old
– with another 400 under construc-
tion. The total water storage capac-
ity of these existing dams is about
283Bm
3
. They have played a key
role in fostering rapid and sustained
agricultural and rural growth and
development – a key priority for the
Government of India since independ-
ence. Irrigated agriculture and hydro
power development have been major
pillars of the government’s strategy
to ensure food and energy security.
“Rainfall, which occurs mainly
in intense and unpre d ictable
downpours within short monsoon
seasons, is of high temporal and
spatial variability and does not
meet year-round irrigation and
other water demands. Considering
this, storage of water is essential
for India. However, many large
dams are in need of modern safety
measures and monitoring instru-
mentation,” said Joop Stoutjesdijk,
Lead Irrigation Engineer and Project
Team Leader. “The project will help
rehabilitate and modernize over
220 large dams in the states of
Kerala, Madhya Pradesh, Orissa,
and Tamil Nadu.”
In addition, the Project also aims
to strengthen the institutional,
legal and technical framework for
dam safety assurance within the
Government of India and in the par-
ticipating states.
Meanwhile, the Punjab Barrages
Improvement Phase II Project aims to
strengthen and modernize Pakistan’s
Jinnah Barrage and afliated works
to enable reliable and uninterrupted
supply of water for over 2.1 million
acres of farmland benetting about
600,000 farm families for irrigation
and domestic water users; and to
build the capacity of Punjab Irrigation
and Power Department’s ( IPD) in
water resource management and irri-
gation system management.
“The development and manage-
ment of water resources of the Indus
Basin is a huge challenge, requiring
very high levels of administrative engi-
neering and scientic capability. While
there has been progress, the current
irrigation and drainage system suf-
fers from deteriorating infrastructure
and weak governance,” said Masood
Ahmad, World Bank Lead Water
Resources Specialist and Project
Team Leader. “To reduce volatility
to growth, Bank support will include
rehabilitation of barrages and con-
tinued capacity development at the
regional and federal level for manag-
ing water resources.”
The World Bank has a long his-
tory of partnership and collaboration
with Pakistan and has supported
more than 48 operations in irrigation,
drainage, water resources develop-
ment and the power sector. Jinnah
Barrage is one of the highest priority
barrages in the Indus System as it
provides a bridge over the Indus River
to link the roads between the Khyber
Pakhtoonkhwa and Punjab provinces.

From the Editor
Dear readers,
Big news from the US this month was that Senator Lisa
Murkowski, Representative of Alaska, introduced two
pieces of legislation aimed at increasing the produc-
tion of hydroelectricity in the country. The Hydropower
Improvement Act and the Hydropower Renewable Energy
Development Act have been developed to boost federal
support for hydropower projects.
In particular, the Hydropower Improvement Act, co-spon-
sored by Sen. Patty Murray, D-WA; Sen. Maria Cantwell,
D-WA; and Sen. Mike Crapo, R-Idaho, aims to increase the
capacity of the nation’s hydropower sources by up
to 75,000MW.
The legislation establishes a competitive grants program
and directs the Department of Energy to produce and
implement a plan for the research, development and dem-
onstration of increased hydropower capacity. The bill also
gives the Federal Energy Regulatory Commission (FERC)
authority to streamline the permitting and review process
for hydropower projects (a move I’m sure would be wel-
comed by the great majority of readers in the US), and calls
for studies on pumped-storage sites and the potential for
development at Bureau of Reclamation facilities.
The Hydropower Renewable Energy Development Act
classifies hydroelectric power generation as a “renewable”
resource for federal program purposes. This bill provides
parity treatment for hydro in the Production Tax Credit
(PTC) and expands the types of hydro that can qualify
for the PTC and Clean Renewable Energy Bonds
(CREBS) program.
When introducing the bills, Murkowski said she hoped
the Senate can finally recognize the important contribu-
tion hydropower, as a truly renewable resource, can
provide to the country’s clean energy goals . Hydropower
is the largest source of renewable electricity in the US,
providing 7% of the nation’s power. In Alaska, hydro sup-
plies 24% of the state’s electricity needs, and there are
more than 200 additional sites that look promising for
further hydropower development.
News of the bills was welcomed by the National
Hydropower Association, particularly the fact that the bill
includes provisions to help make existing hydro resources
more efficient, convert existing dams to energy-generating
resources, and support small conduit technologies, as well
as pumped-storage project development. “This approach
focuses on new technologies and new approaches, not
necessarily new dams,” said NHA Executive Director Linda
Church Ciocci, adding that the association stands ready
to work with Congress, the White House, and other stake-
holders to ensure that hydropower is supported in any
energy and/or climate bill that moves forward.
There is little doubt this is a great step forward for hydro
in the US, and is a great sign for the future. It would allow
the country to expand its exisiting developments and
ensure continued development of new technologies, as
well as offering extensive employment opportunities.
Best wishes

NYPA plans $460M upgrade for
part of Niagara power project
T
HE NEW YORK POWER AUTHORITY
(NYPA) is planning a major
overhaul of the Niagara Power
Project’s Lewiston Pump Generating
Plant (LPGP) to extend the life of the
hydroelectric project’s auxiliary facility
and enhance its performance.
The Power Authority Board of
Trustees approved a $460M Life
Extension and Modernization (LEM)
Program for the LPGP facility, which
operates during periods of peak
power demand in supplementing the
electricity output of the Robert Moses
Niagara Power Plant, the Niagara
Project’s main generating facility.
The trustees also authorized initial
capital expenditures of $131M for the
upgrade and the award of a 10-year
contract to Hitachi Power Systems
America, which was the lowest-cost
qualied bidder for replacing and mod-
ifying major components of LPGP’s
pump-turbine generators.
“The Niagara Power Project is a
tremendous asset to Western New
York in providing some of the lowest
cost electricity in the country, with
its power production supporting
tens of thousands of jobs on the
Niagara Frontier,” President and
Chief Executive Officer Richard M.
Kessel said, announcing the upgrade
project. “The Power Authority places
the highest priority on being a good
steward of this facility to ensure it
continues to bring the greatest value
to the region’s economy and the
state’s electric power system. The
Life Extension and Modernization
Program that we’re planning at the
Lewiston Pump Generating-Plant is
in keeping with this imperative, which
also served as the basis for the
Power Authority’s completion only a
few years ago of a similar program at
the Niagara Project’s Robert Moses
Niagara Power Plant.”
In 2006, NYPA completed a $24M
maintenance program at LPGP in the
same year that it nished a $298M,
15-year program to upgrade the
Robert Moses Niagara Power Plant,
where the Power Authority replaced
turbines and retrotted other compo-
nents of all 13 generating units. The
LEM at the pump generating plant will
be an undertaking of similar scope,
for overhaul of the plant’s 12 pump
turbine generator units, which date
back to 1961, when the Niagara
project was rst placed into service.
The work will include replacing the
turbine runners, the rotating portion
of the equipment. The runners, which
typically weigh about 75 tons, trans-
fer energy from the water ow to the
generators.
The upgrade will begin in late 2012
under a schedule providing for the
overhaul of a turbine generator unit
every eight to nine months, with the
final unit completed in 2020. The
phase-in schedule provides for 11
of the 12 LPGP units to be available
for operation during the LEM so that
NYPA can meet its commitments to
its customers.
In addition to extending the life
of the pump generating plant, the
refurbishing will lead to greater ef-
ciencies, allowing the plant to gener-
ate additional power with the same
amount of water.
LPGP is one of two major pumped
storage facilities in New York State -
the other being the Blenheim-Gilboa
Pumped Storage Power Project, anoth-
er NYPA facility. In May, the Authority
completed a four-year overhaul of that
facility, in the northern Catskills.
The selection of Hitachi Power
Systems America for replacing parts
of the pump-turbine generators and
associated equipment stemmed from
a Request for Proposals that NYPA
issued last December for the new
equipment and rehabilitation work. The
company, which was one of six bidders
submitting proposals in response
to the RFP, was awarded a $174M
contract for carrying out the overhaul
during the 2012 to 2020 time frame,
with the contract amount including
allowances for future ination.
Hitachi was also the company that
upgraded and rehabilitated the pump-
turbine units at Blenheim-Gilboa.
Hitachi and other contractors are
expected to utilize local union trades
people, including machinists, electri-
cians, mechanics and welders, in sup-
port of the LPGP work, contributing to
economic development in the region.
The work will include the disassembly
and reassembly of equipment.
NYPA is also currently conducting a
LEM program at another hydroelectric
project, the St. Lawrence-Franklin D.
Roosevelt Power Project in Massena.
That initiative is more than three-
quarters complete and scheduled to
be nished by 2013.
Andritz resumes Ilisu supply contract
T
ECHNOLOGY GROUP ANDRITZ
says that it is to resume its con-
tract to supply equipment to the
Ilisu hydro power plant in Turkey after
improvements were made to aspects
of the project’s environmental and
social measures.
The supply contracts awarded to
Andritz as well as a number of other
European rms were suspended tem-
porarily in late 2008 after the export
credit agencies of Austria, Germany
and Switzerland said that specied
standards relating to the project’s
impact on the environment, cultural
heritage and resettlement had not
been fullled.
Andritz’s EUR340M contract
includes the supply of engineering
services, six 200MW Francis tur-
bines, six generators and additional
equipment. The company is part of an
international construction consortium
led by Turkey’s Nurol Construction.
According to Andritz, its contract will
no longer be supported by the Austrian
export credit agency, Oesterreichische
Kontrollbank AG (OeKB).
In 2009, OeKB and two other
European banks withdrew their sup-
port for Ilisu after a deadline that
had been set for socio-economic and
cultural improvements to the project
was not met. The banks’ support
was designed to cover the European-
based suppliers for the project,
including Andritz, Alstom, Ed. Zublin
AG, Colenco and Maggia.
Turkey, which sees the EUR1.2B
project as a key element of its social
and industrial development plans,
vowed to continue with Ilisu without
the banks’ support. According to a
statement from Andritz, the Turkish
government says that “it will abide
unchanged by the planned accompa-
nying measures relating to environ-
mental protection and to social and
cultural aspects”.
Ilisu is part of Turkey’s Southeastern
Anatolia Project, which aims to build
22 dams and 19 power plants on the
Tigris and Euphrates rivers and their
tributaries.

10 JULY 2010 INTERNATIONAL WATER POWER & DAM CONSTRUCTION
INSIGHT
T
HE economic downturn has
changed the contract delivery
methods for many infrastructure
projects in Europe, the Middle East
and Africa (EMEA). An example of which is
a trend of fewer cost-reimbursable contracts
and more lump sum contracts. Additionally,
public private partnership delivery is being
implemented on many infrastructure projects,
and even recent hydropower projects have
seen governments tender for private con-
cessionaires to design, build, operate and
transfer these projects. As contract delivery
methods change, it transfers the risk alloca-
tion between the parties, which should be
considered in the risk assessment and affects
the structure of disputes.
Recent industry trends indicate that
construction disputes are on the rise.
Additionally, owners and contractors are
continuously trying new, alternative methods
of dispute resolution to minimise the time
and cost to settle their disputes.
In general, disputes are driven by change,
regardless of a project’s geographic location.
Additionally, changes in construction today
are still driven by the same common project
conditions that have driven changes in recent
decades, such as differing site conditions, errors
and omissions, owner-directed changes, etc.
What has changed as a result of the cur-
rent economic conditions and political envi-
ronment is the way projects are approached,
executed and managed. More focus and
exposure appears to be directed at the pre-
planning phases, which heightens the need
for a transparent risk management pro-
gramme. Owners are looking more aggres-
sively at ways to better manage costs, while
contractors are actively seeking options to
protect or improve tighter prot margins.
Hydropower projects
Marsh Construction Consulting profession-
als have been engaged in numerous hydro-
power projects in Europe and Asia. These
projects range from combined irrigation
and hydroelectric projects to hydropower
programmes of multiple power generation
stations. Additionally, our experience has
included consulting for both developers and
contractors, providing services throughout
the project life cycles. This has allowed a
balanced perspective in identifying con-
struction risks during development phases,
resolving disputes during negotiations, and in
some cases providing expert analysis and
testimony in International Chamber of
Commerce (ICC) arbitration.
As an indication of a representative
engagement, Marsh consultants were
retained on a hydropower plant that was a
joint implementation project between two
European countries within the framework
of the Kyoto Protocol. The project had
some unique aspects as it was designated as
a pilot project located in a mountain range
at a country border, and was to be part of
a string of power stations along the nearby
river. The above-ground storage power sta-
tion had an installed capacity of 80MW and
a standard production of 185GWh/yr, while
the reservoir had a volume of 111Mm
3
and
was contained by a 125m high arch dam.
The conventionally driven intake water
tunnel partly cut across a geologically problem-
atic zone. While all projects contain their own
unique issues, the political prole and challeng-
ing site conditions added an element of risk for
which Marsh professionals were engaged to
analyse and identify areas of impact, delays,
and potential risk for the project.
The need for risk assessments for these
infrastructure projects varies signicantly;
based on the types of projects and the capac-
ity in which these assessments are conducted.
For example, in one particular engagement,
Marsh Construction Consulting profession-
als led a risk assessment and contractor esti-
mate validation exercise of a multi-billion
US dollar landmark submersible ood gate
system in Italy. In this case, the need was for
a detailed quantitative risk assessment of the
cost to complete the ten-year programme.
From this assessment, we were able to pro-
vide a specic recommendation on the appro-
priate allocation of risk in the EPC contract
and determine the appropriate range of con-
tingency for the programme. Studies such as
this are often used as the basis to approve
funding for unique ‘one-of-a-kind’ projects.
Insurance claims
Specic industry expertise has proved valu-
able in assisting with insurance claims related
to hydro construction projects. For example,
to address a force majeure event (ood) on a
hydroelectric station in Asia, Marsh formulat-
ed a written acceleration plan for submission
to the insurers. This plan specically outlined
the parameters and components of the mitiga-
tion and recovery of the time impact of the
force majeure event on project completion.
In order to adequately address these
specic needs of owners and contractors for
risk assessments and claims services, signi-
cant expertise across multiple disciplines is
required. Additionally, to continue to add
value to hydropower and dam clients, it is
imperative that construction professionals
stay abreast of the dynamic environment in
which these projects develop. While this can
prove challenging, it’s also a very interesting
time for nding hydropower solutions, given
the current focus on renewable energy and
environmental concerns.
project controls
It has always been good practice to imple-
ment reliable project controls and project
governance methods for large, complex con-
struction projects. However, today’s dynam-
ic political and economic environment has
placed an increased emphasis on hydropower
projects in particular. When these factors are
combined with balancing the world’s grow-
ing energy needs with an intense focus on
renewable energy sources and environmen-
tal concerns, creative solutions are needed to
address these challenges.
One could say there’s less room for error in
this environment, or put another way, it will
be more costly to address changes or risks
that are not identied and mitigated early in
the project life cycle. Additionally, ensuring
that the best practice project controls and
governance procedures are in place for a par-
ticular project is not enough. It is becoming
more and more important to ensure proper
implementation of these controls at every
step throughout execution.
Most will agree the level of scrutiny in
which these projects are designed, built, and
operated has increased in the last decade. The
need for improvement goes beyond advanc-
ing the methods of execution with technol-
ogy improvements. It means understanding
how risks are transferred amongst the parties
throughout the project life cycle, as contract
delivery methods, funding mechanisms, and
stakeholder needs continue to evolve. It’s
not just the project success goals that have
changed in the last decade, but the ways in
which we achieve those goals and the tools we
have developed to ensure transparency and
control throughout the life cycle.
