Alstom to install environmental systems at UK’s second largest power plant

2 May 2006 – ScottishPower has taken action to ensure the long-term operation of one of the UK’s largest power generators by awarding an environmental retrofit contract to a consortium led by Alstom.

The total contract value to the Alstom/AMEC consortium is over €200m ($253m), of which Alstom’s share is in excess of €90m.

The order follows ScottishPower’s recent decision to opt into the Large Combustion Plant Directive (LCPD) concerning Longannet Power Station. This will consequently remove the 2304 MW plant from restrictions that would otherwise have forced its closure by 2015. The power plant is the second largest in the UK and generates over 25 per cent of Scotland’s annual electricity requirements.

Alstom will supply a seawater flue gas desulphurization (SWFGD) air pollution control system that will reduce sulphur dioxide emissions in line with the most stringent EU emission requirements, as specified in the LCPD.

The installation of the system will permit Longannet Power Station to burn significant quantities of indigenous coal.

Alstom and AMEC will be jointly responsible for the project management. Alstom will supply all the air pollution control systems and components, while AMEC will be responsible for the site management, civil and structural design and construction.

The Alstom SWFGD system uses the power plant’s seawater cooling water for treating the sulphur dioxide from the flue gas. The process does not require the addition of any chemicals, only seawater and air are used, and the discharged seawater fully complies with environmental regulations.

This is the third major contract Alstom has won for a SWFGD system in the UK over the past year, following the award of Kilroot Power Station from AES and Aberthaw Power Station from RWE power in 2005.

In another environmental upgrade contract, Alstom has been awarded a €26m contract by Louisa Environmental Power Partners to supply air pollution control systems for MidAmerican Energy Company’s 700 MW coal fired power plant, located in Muscatine, Iowa.

The air pollution control system is designed to reduce emissions of particulate matter and sulphur dioxide and will, in addition, enable the plant to comply with forthcoming environmental requirements.

Under the contract, Alstom will supply two of its spray dryer absorber dry flue gas desulphurization (DFGD) plants, two pulse-jet fabric filters for particulate removal and associated equipment.

The project is scheduled for completion in January 2008.
