Operation & Maintenance of Power Plants
Tis boost in operational flexibility is particularly important in the highly-competitive Texas electricity market where plants are often called on to rapidly increase and decrease power output. “Alstom has invested heavily in advancing its natural gas power generating technologies to better meet the long-term needs of its customers,” according to Hans-Peter Meer, senior vice president of Alstom’s thermal services business. “For GDF SUEZ Energy North America, those investments will translate into bottom-line benefits once the GT24 upgraded fleet is performing to the new standard in operational flexibility.”
Te four power stations included in this agreement constitute the largest fleet of Alstom GT24 gas turbines owned by a single customer, and the company has provided service support for the plants since they entered commercial service.
the reconstruction and upgrade of the Cascade Kubansky hydro power plants. Te project is for the modernisation of eight hydropower plants and the pumped storage plant. Alstom will manufacture and deliver the equipment as well as supervising the installation, tests and commissioning of the power plants, using its advanced technical know-how and state-of-the-art technologies, particularly for the automation of the Nevinnomyssk control centre.
“Reliability, flexibility, and efficiency drive performance in our generation business…”

Hydro plant upgrade Meanwhile RusHydro and Alstom have signed two agreements extending their co-operation within the AlstomRusHydroEnergy joint venture (JV) for the reconstruction and upgrading of the Cascade Kubansky hydro power plants in south Russia. Te first agreement covers the strategic development of AlstomRusHydroEnergy. With the aim of strengthening the cooperation of the two companies in the field of hydro power, the agreement extends the scope of the JV to services including the inspection of power plants, supply of spare parts and components, retooling and the repair and upgrade of equipment. Both parties also intend to extend their cooperation to include innovation and R&D activities. Te second agreement details the key principles and timelines of the contract signed in 2011 for
Diablo Canyon contract extension For its part, Fluor has announced that Pacific Gas and Electric (PG&E) has awarded the company an extension of its operations and maintenance (O&M) contract for work at PG&E’s Diablo Canyon Power Plant Units 1 and 2 in Avila Beach, California. At Diablo Canyon, which
produces 18,000 GWh annually, Fluor will continue
to provide ongoing maintenance, modification and outage services for PG&E’s two nuclear generating units. Te work encompasses mechanical, electrical and civil tasks during non-outage and outage periods. Fluor was awarded the initial O&M contract in May 2010. “Fluor is pleased to extend our operations and maintenance services for PG&E,” said Matt McSorley, senior vice president and head of Fluor’s Power business. “Diablo Canyon features an exemplary safety record while providing clean, reliable energy to millions of Californians. Fluor looks forward to continuing that tradition of safety excellence while maintaining this significant facility.” Te Diablo Canyon power plant, which has operated since 1985, features two pressurised water reactor units to produce energy for more than three
Yokogawa eyes Korea expansion Y
okogawa Electric Corporation subsidiary Yokogawa Electric Korea has won an order from
Korea South-East Power (KOSEP) to supply control systems for the number 1 unit of the Yeosu thermal power plant in the city of Yeosu, which is located in Korea’s South Jeolla Province. The Yeosu plant has a 200 MW heavy
oil-fired unit and a 329 MW coal-fired fluidised bed (CFB) unit with a current total capacity of 528MW. The number 1 heavy-oil fired unit is going to be replaced with another coal-fired CFB boiler and a steam turbine that will generate 350MW.

The renewed unit is scheduled to start operation in November 2015. This order is for a comprehensive range
of control and instrumentation including CENTUM VP integrated production control systems for the power plant’s boilers, turbine, and auxiliary facilities as well as engineering and installation. While turbine manufacturers generally also supply the control systems for their products, Yokogawa will be providing the turbine control system for this project. Yokogawa Electric Korea has
recently received many orders for international projects undertaken by
Korean engineering, procurement, and construction contractors, and is a top supplier of control systems in its home market. The company says it was able to win this order because of the high reliability of Yokogawa’s control systems, its excellent engineering capabilities, and its comprehensive maintenance services. Encouraged by the success in winning
this order, Yokogawa says it will expand its power business in Korea by offering appropriate solutions to developers of innovative technologies that generate power more efficiently and are environmentally-friendly. ●
