Lisheen Wind Farm

SWS Natural Resources

Lisheen Wind Farm in North Tipperary, Ireland, features 18 wind turbines with a generating capacity of 50MW – enough to power 50,000 homes. Built on the grounds of a working mine, it features some of the largest turbines in Ireland and displaces 100,000 tonnes of carbon dioxide emissions each year.

As the EPC contractor on site, we managed and controlled the full turnkey project from initial design, through to construction and commissioning,and created more than 70 local job opportunities throughout the project.

Substation Control System upgrade

South East Electricity Substation Alliance (SEESA)

SEESA is led by National Grid working in a partnership with Alstom, Skanska and Mott MacDonald. The alliance carried out a significant upgrade and extension of the substation control system (SCS) at New Cross in London.

We were engaged to implement a Type Registered SCS solution based on a GE Digital Energy Remote Telemetry Unit (RTU). To ensure that the region continues to enjoy safe, secure and reliable electricity supplies in the future, this featured D25 technology, and COPA-DATA for the incumbent HMI to support additional plant at the substation and help reinforce National Grid’s network.

Gwynt y Môr Wind Farm

Harland and Wolff Heavy Industries

Gwynt y Môr (‘wind in the sea’ in Welsh) is the second largest operating offshore windfarm in the world, consisting of 160 wind turbines in Liverpool Bay, off the North Wales coast. The project was funded by RWE Innogy, in partnership with Stadtwerke München GmbH, and Siemens AG. It is capable of generating enough energy to meet the average annual energy needs of around 400,000 homes.

Working on behalf of contractor, Harland and Wolff, we were responsible for the design, supply and installation of the air conditioning systems for the equipment rooms and temporary living quarters on two of the wind farms’ substations, which are located offshore in a very demanding environment.

Energy Spend Reduction

Thames Water Utilities Ltd

Thames Water and its energy consultants SKM Enviros and Grontmij identified 22 sites across North and South London and the Thames Valley, which were responsible for a considerable percentage of Thames Water’s energy spend.

We installed over 800 energy meters at the sites, with the aim of reducing each sites energy consumption and ensuring a substantial cost saving year-on-year. In addition to the meters, we installed cabling and interfaced them to the incumbent Programme Logic Controller and Supervisory Control and Data Acquisition (SCADA) systems on site. We also created new SCADA screens to display operational data to site operators to enable optimised site performance.

Biomass Co-firing Facility

Drax Power Ltd

Drax Power Station is the largest, cleanest and most efficient coal-fired power station in the UK.  It has six 660MW generating units producing 4,000MW of electricity.  Its biomass co-firing facility is the largest of its type in the world, capable of handling around 1.5 million tonnes of biomass per year.

We provided the process control and the real-time data management systems to enable the  biomass co-firing facility to be operated efficiently and safely, whilst providing fuel accountancy for all materials processed by the plant.  We integrated a system with the ability to control the new plant areas, whilst interfacing and integrating with the existing six generating control and materials handling systems we had previously installed.

Lancashire Waste Management

Global Renewables

The introduction of two new mechanical biological treatment plants in Leyland and Thornton has seen Lancashire become one of the leading areas in Europe for environmentally friendly waste management. These were developed in partnership by Lancashire County Council, Blackpool Council and Global Renewables, as part of a £2 billion waste contract.

We installed and implemented plant-wide control systems at both sites based on Siemens S7 PLCs and WinCC SCADA.  As well as providing a graphical overview of the whole waste treatment process, all plant data is logged and stored for retrieval and analysis, assisting in plant performance optimisation at the state-of-the-art facilities.

Energy Management TSV Project

Yorkshire Water

Yorkshire Water identified the need for high quality operational information to help improve business performance. Its existing information solutions were complex to maintain, and the company was mindful of their limitations with regard to the collection and analysis of real-time data. Consequently, concerns about the system’s future sustainability prompted it to seek a modern, scalable and maintainable alternative.

Our solution, as part of Yorkshire Water’s Time Series Values (TSV) project, utilised the PI System infrastructure from OSIsoft. This allows Yorkshire Water to monitor key parameters from its field assets across its territory. We created production dashboards which enabled operators to centrally monitor the performance of 55 strategic sites within the company’s portfolio. The central monitoring and intelligent alarm management enabled better targeting of maintenance resource and facilitated effective business decisions as a result.

Distribution Network Visibility

UK Power Networks

The UK Power Networks’ Distribution Network Visibility Project was funded by the Low Carbon Networks Fund.  The purpose of the Distribution Network Visibility Project was to develop a smart central repository for data from existing operational and business systems.  This is then combined, transformed and visualised to provide greater understanding of the interactions across the network.

We developed a software tool to interface with the central data repository based on the OSIsoft PI System and implemented a series of models, analytical approaches and visualisation solutions which allows raw data to be turned into meaningful operational information.

Bagnolo Biomass Plant

Biomass Power Ltd

Biomass Power (BPL) built a ground-breaking new 3.5MW biomass plant in Bagnolo, near Venice in Italy.  In contrast to traditional large-scale vertical biomass gasification processes, BPL confines its entire process technology solution within sub-10 metre high buildings.

We worked closely with BPL from the early stages of this project to understand and develop the project requirements, from which we developed the full project specification.  We implemented a DCS control solution for the gasifier, boiler and dust filter processes using Siemens PCS7 technology to significantly enhance the plant control and maximise performance.  We also provided an uninterruptible power supply, control desk and control panels, and assisted in on-site commissioning.

Leitir Gungaid Wind Farm

Leitir Gungaid Wind Farm is situated on the Atlantic coast, 9kms west of Galway, Ireland. It became operational in July 2014 and has a capacity of 44MW. The expected annual electricity generation via its 17 turbines is 130GWh, which will power approximately 30,000 homes across Ireland and save 75,000 tonnes of CO2 each year.

We undertook the full engineering, procurement and construction project on this development, including installation of ducting and cabling at the newly built substation on-site to enable connection to the National Grid. The team also carried out civil and engineering works to the new 50Mva transformer and WTG Collector system and installed numerous cabling, control panels and earthing systems to the facility.
