SMALL HYDROPOWER PROJECTS

Black & Veatch has been providing services to the hydropower industry for almost 100 years. We have worked on major projects across the water and energy industries and are actively engaged in projects from early concept definition and research to turnkey project execution.

EXTENSIVE KNOWLEDGE OF RENEWABLE ENERGY

Black & Veatch has extensive knowledge

of all aspects of renewable energy.

Our experience ranges from small 10kW

systems for our water utility clients,

to run-of-river plants of less than 1MW

to large-scale utility generation greater

than 1000MW.

Whatever your requirements, we can

help you identify, evaluate, design and

implement the right solution to meet

your needs.

DESIGN, CONSTRUCTION & INSTALLATION SCOTTISH WATER HYDROPOWER SCHEMES | Scottish Water |

Scottish Water has an ambitious target to generate more power than it

consumes by 2018. Black & Veatch has helped to deliver a large component

of this target by completing six hydro turbine installations across five sites.

These consisted of both on and off site schemes; turbines being placed on

compensation flow lines to rivers and on raw water intakes to treatment works

for example.

Scottish Water initially undertook a feasibility study of 45 potentially suitable

sites, of these it was concluded 33 of the sites could be used to generate power

from hydro turbines. For 8 of these sites, Black & Veatch undertook an outline

design to devise a ranking of the sites based on their economic viability.

On the basis of their ranking, Black & Veatch was awarded design-and-build

contracts for delivery of 5 turbine installations across 5 sites, with a sixth

already having been completed at Glencourse in 2012.

For those sites chosen to be developed, power generation potential varied

between approximately 100 to 700kW. In all cases, the available head is

greater than 10 metres (m), with the highest being 83m. Flows range from 100

to 1,700 litres per second (l/s). Delivery was a multi-disciplined undertaking,

encompassing planning, modelling, design, specialist hydropower technical

expertise and construction management.

Each site had its own set of complexities, but all of the projects shared the

common aims of limiting the impact on existing operations whilst maximisating

of output and efficient performance. The integrated design and build team

addressed buildability issues at an early stage and ensuring efficiencies across

the programme. Importantly, the use of an integrated team has also helped

improve construction safety.

SELECTED PROJECT EXAMPLES

BL ACK & VEATCH

PENYCEFN WATER TREATMENT WORKS | Dwr Cymru Welsh Water |

Black & Veatch has completed the design, procurement,

installation and commissioning of a hydropower facility at

Penycefn Water Treatment Works. The scope was agreed

following a renewable technology cost/benefit study by

Black & Veatch and was part of the concurrent works upgrade.

The 16kW hydro device has a regulation function allowing flow

control as well as energy recovery for electricity generation.

PENYCEFN WATER TREATMENT WORKS | Dwr Cymru Welsh Water |

A similar, but larger installation is now operational for Crai Water

Treatment Works in South Wales. The installation at Crai,

however was particularly challenging due to its location in the

Brecon Beacons National Park.

Black & Veatch’s experience of obtaining planning permission

for such installations, ensured that Dwr Cymru secured planning

consent and the design of the scheme incorporated a number of

environmental and ecological elements to realise a ‘conservation

considerate’ scheme.

GLENCORSE WATER TREATMENT WORKS (WTW) | Scottish Water |

Black & Veatch completed the design and managed the

installation of a 230kW Turgo hydroturbine at Glencourse Water

Treatment Works. Glencorse provides a reliable and safe drinking

water supply for 450,000 people across Edinburgh and parts

of Midlothian. Not only does the scheme provide 20% of the

facility’s needs, it ensures sustainable economic growth for

the region by allowing the plant to be scaled up to meet

future demands.

Sustainability and community have been at the project’s heart

throughout planning, design and execution. The WTW’s size and

visual impact was reduced significantly through Black & Veatch’s

choice of treatment process. Using grass roofs for the largest

structures also helped blend the works into its surroundings.

Producing pipes adjacent to the site cut costs and carbon

emissions in addition to making construction safer and easier.

Glencorse has won an impressive ten awards, including;

�� CIWEM World of Difference - 2011

�� CCS Considerate Constructor Gold - 2012, 2011 & 2010

�� RoSPA Gold - 2011, 2010 & 2009

�� Scottish Water Excellence in S-afety - 2009

�� CeeQual Whole Project - Excellent (84%)

�� CeeQual Outstanding Achievement - Relations with the Local Community & other Stakeholders

CONCEPT DESIGNLOW-HEAD HYDROPOWER GENERATION IN AN EXISTING FACILITY | Thames Water |

Black & Veatch investigated renewable energy generation for an

existing water management structure. A run-of-river ‘mill’ which

used to power water distribution pumps was made redundant

in 1983. Black & Veatch completed a concept design study for

using the facility to generate electricity.

HYDROPOWER GENERATION AT HAMPTON WATER TREATMENT WORKS | Thames Water |

Black & Veatch reported on the viability and prepared a concept

design with indicative cost estimates for a hydropower scheme

located at the Hampton water treatment works.

Black & Veatch undertook a comprehensive review, offering

specific advice on: dynamic heads and flow rates, energy recovery

management and yield, turbine types and selection, failure

scenarios and pressure transients, spatial planning, operation

risks, integration with the existing site and maintenance issues

and costs.

FEASIBILITY STUDIESSCOPING ASSESSMENT OF HYDROPOWER FEASIBILITY AT FIREPOOL WEIR | Environment Agency |

As part of a larger weir development, Black & Veatch carried

out a high level review of a hydro scheme at Firepool Weir.

This review, which covered an investigation of the opportunity

for an Archimedes screw generator, included an analysis of the

flow duration curve, preliminary sizing of the plant, predicted

energy capture and the capital investment required.

The analysis also looked at the revenue that could be generated

from Feed-In Tariffs and gave an appraisal of both the investment

case at the site and the potential CO2 savings.

TWO HYDROPOWER SCHEMES | Confidential Client |

Black & Veatch provided the client with two feasibility reports for

two separate potential hydropower schemes (30-70kW) in Wales.

An estimation of the potential energy yield was made by

considering the gross head, flow duration curve, hydraulic

losses and mechanical and electrical efficiencies.

The work included carrying out pressure tests to obtain an

accurate hydraulic characteristic curve for each scheme.

Based on this information, turbines were selected and the

mechanical and electrical layouts presented. Feasibility was

then assessed taking into consideration the capital and operating

costs and all potential revenues.

SIX HYDROPOWER SCHEMES | Confidential Client |

Black & Veatch provided the client with a pre-feasibility report

for six potential mini hydropower installation sites (20-100kW)

in England. For each site a hydrological assessment and site

visit were carried out. An estimate of the potential energy yield

was made by considering the gross head, flow duration curve,

hydraulic losses, and mechanical and electrical efficiencies. An

overall project layout and preliminary estimation of the capital

costs of the project were determined.

HYDROPOWER SERVICES FRAMEWORKUNITED UTILITIES OPERATIONS SERVICES | UUOS |

Black & Veatch was a framework partner for the provision of

hydropower development services for United Utilities within the

Welsh Water region. Black & Veatch carried out three hydropower

appraisals (<50kW), two of which were progressed to installation

under the management of Black & Veatch.

DEVELOPMENT STUDY FOR WALES | Environment Agency |

As part of a UK wide Carbon Reduction Plan for the Environment

Agency, Black & Veatch reduced a list of over 60 potential

hydropower sites in Wales to a shortlist of five by means of

a desk study. Following site visits, Black & Veatch produced

environmental, economic and planning appraisals with outline

designs for the selected sites. Wind and solar photovoltaic

renewable energy applications were also included in the study.

RESOURCE STUDY FOR SCOTLAND | Scottish Government |

Black & Veatch provided technical and financial expertise on

small hydropower feasibility studies. The conclusions of our

appraisals fed into the survey of hydropower resource across

Scotland, with the final study being completed by Nick Forrest

Associates in collaboration with the Scottish Institute of

Sustainable Technology (SISTech).
