Recent power plant contract awards1 June 2001
• GE International has won a contract worth more than $100 million from Termogaucha-Usina Termeletrica SA, a project company based in Porto Alegre, for equipment and services for a new 500 MW power plant to be constructed in southern Brazil. The plant will be at South Petrochemical Complex - Triunfo, in Rio Grande do Sul. GE is to supply two PG7241FA gas turbine generators and one steam turbine. The company’s contract also includes technical advisory services and training.
The two gas turbines for the project will be manufactured in Greenville, South Carolina and shipped to Brazil late in 2002. The steam turbine will be provided by Japanese company Hitachi and will be shipped in the late summer of the same year. Generators will be provided by Mitsubishi Electric Co.
The new plant is due for completion in 2003. Base-load operation is due to commence early in 2004.
The combined cycle project is expected to be the anchor for a pipeline that will transport natural gas from the Argentine border region of Uruguaiana to the Porto Alegre region.
Termogaucha is a consortium including the regional Brazilian utility CEEE and three oil and gas companies, Companhia Brasileira de Petroleo Ipiranga SA, Petroleo Brasileira SA Petrobras and Repsol YPF Brazil SA.
• The Shangdong Zhanghua Power Co has ordered control systems and field instrumentation for two new coal-fired power plants from ABB Automation. The two plants are due to enter service in Shangdong province in 2002. The equipment will be used to control two 600 MW turbine generators being constructed on a new site at Liaocheng and two 300 MW units which are being built to augment existing generating capacity at Heze. The systems will be employed to control the full process, from the movement of coal through its process stages in the mills to boiler management and the generation of electricity for the local grid. Field instrumentation will include pressure transmitters and flame monitoring equipment for burner protection.
• Austrian company VA Tech Hydro has signed two contracts in China relating to hydropower schemes. The Anhui Langyashan Power Co has awarded a contract to the company to erect the Lang Ya Shan pumped storage hydropower project. The 700 MW station is expected to enter service in four years. VA Tech Hydro will import pump-turbines, turbine governors, motor-generator sets, voltage control equipment, transformers, switchgear and protection and control equipment for the project. Meanwhile the Liuzhou Guiliu Hydropower Co Ltd in Guangxi has commissioned the Austrian company to supply bulb turbines, generators and transformers for the Dapu hydropower station. The plant will have a generating capacity of 98 MW, supplied from three 32.6 MW turbines. The scheme, due for completion in 2003, will also provide irrigation and flood protection.
• The Electricity Supply Board of Ireland has selected ABB to expand and upgrade the power network in and around the Irish capital, Dublin. The work represents part of an ongoing infrastructure development plant to help the country fulfil its ambitions to become a European centre of electronic business. The contract, worth $14 million, involves an initial order for four substations. The project will involve upgrading 110 kV and 20 kV substations in the Dublin area.
• The UK company Beel Industrial Boilers has completed its largest ever order, the manufacture and supply of ten boilers for five sites in Turkey. The order, worth close to $3 million, was placed by Alstom Power which is supplying ten cogeneration plants to AK Enerji for installation at paper mills and textile plants in northern Turkey. Each system is based around a Typhoon gas turbine and will provide 5.25 MW of power and additional steam for the manufacturing processes.
Each of the ten boilers will capture exhaust heat from one of the turbines, raising 11 500 kg/h of saturated steam at 10 barg. Each boiler is fitted with a control and instrumentation package, and economiser, divert damper and by-pass chimney to maximise efficiency across a wide range of operating conditions. Beel will be responsible for installation, commissioning and staff training.
• Scottish and Southern Energy (SSE) has signed a $120 million long term service agreement with Siemens covering specialist labour and parts for three combined cycle gas turbines recently installed at the Peterhead power station in Scotland. The $300 million repowering project was completed in 2000, increasing efficiency of the plant from 38 per cent to nearly 57 per cent. The service agreement will help SSE to maintain high availability at the plant. The New Electricity Trading Arrangements in the UK particularly reward availability.
• Plug Power Inc has announced a $7 million deal with a public utility for 75 of the company’s commercial fuel cell systems, together with installation, maintenance, service and training. The deal, which includes the development of remote dispatch software, will start this summer. The aim is to gain experience of the operation, control, grid interconnection, environmental effect and operating modes of fuel cell units to support utility applications including residential distributed generation.
The company has also completed testing and evaluation of its fuel cell units for CSA International certification and has received approval to produce units bearing the CSA international certification seals for the USA.
• Pennsylvania company PPL Susquehanna has awarded a nuclear turbine upgrade contract to Siemens Westinghouse Power Corp. Under the terms of the contract, Siemens Westinghouse will design, manufacture and install turbine upgrades for two 1130 MW nuclear units at PPL Susquehanna’s Steam Electric Station in Berwick, Pennsylvania. The project is intended to extend service life and improve unit efficiency, increasing power output from the two units.
The upgrade includes turnkey installation of one high pressure and three low pressure rotors in each of the two turbine generators. The eight rotors will be designed and built at Siemens’ plant in Mulheim, Germany. The first upgrade, on unit 2, will take place during a refuelling outage in the spring of 2003, the second during the spring 2004 outage.
• The New Jersey Board of Public Utilities has selected Electrotek Concepts and Conectiv Power Delivery to assess distributed generation as a way to reduce costs and improve service delivery reliability for Long Beach Island, New Jersey. The contract is funded by the US Department of Energy. Distributed generation will be investigated as an alternative to traditional expansion of transmission and distribution systems. The project will involve three phases. In phase one a modelling tool will be used to undertake a technical and economic analysis of the Long Beach Island system to discover where distributed generation might be applied. Phase two will involve procurement and installation of distributed generation technologies including fuel cells and microturbines. The third phase will centre on the field testing of selected distributed generation technologies.
