Gaz de France award Alstom power plant contract

7 May 2002 – Alstom announced today the award of a contract with a total value of approximately €450m for the turnkey supply of an 800 MW gas-fired power plant to be built at Dunkirk, on the northernmost tip of France. Gaz de France Group will own the plant.

This contract includes an agreement for a 20-year maintenance service package for the gas turbines which is currently being finalised. The package covers operation and maintenance support, as well as scheduled and unscheduled maintenance, including supply and refurbishment of spare parts and supervisory personnel.

Alstom will deliver two 400 MW power trains, each composed of one GT13E2 gas turbine fired by natural gas, one gas-fired boiler running on blast furnace and coke-oven gases from the nearby Sollac Atlantique steel works (Arcelor Group), one 235 MW steam-generator set, the cooling water system, the complete advanced electrical and control system and all electro-mechanical auxiliaries.

The plant will be able to operate flexibly in various modes, with or without the gas turbines in operation, with a view to both optimally converting into electrical power the gases available from the steelworks and offering electrical power to the market.

Arcelor is the leading global steel maker specialising in the production, processing and distribution of high value-added steels.

The commercial operation of this combined cycle power plant is scheduled for February 2005. The construction schedule will be in line with the planning for obtaining the required approval for the operations.

This order brings the total of GT13E2 machines sold to 75 units. The fleet has accumulated more than 1 300 000 operating hours.

“Naturally we are delighted to be awarded this contract,” says Alexis Fries, President of Alstom’s Power Sector. “Not only is this the first reference in France for our GT13E2 gas turbine technology, it is the largest combined cycle project and the first of its kind in France. The plant will produce electricity flexibly from natural gas and steelworks gases, with high thermal efficiency and low carbon and nitrogen oxide emissions. We look forward to working closely with Gaz de France and all concerned to secure successful project completion and we are committed to meet our customer’s expectations for top-class service support for long lasting safe and profitable operation of the gas turbines.”

Switchgear contract

Alstom also said today that UK transmission operator National Grid plc has awarded it a turnkey contract worth over €11m($10.06m) to upgrade a 132kV substation with gas-insulated switchgear (GIS), on behalf of its customer Southern Electric Power Distribution Ltd.

Under the turnkey contract, Alstom’s Transmission and Distribution (T&D) Sector will supply and install 15 bays of the company’s new F35 high-performance GIS at the substation at Laleham, west of London.

Alstom said the innovative design of its compact solution gives National Grid increased switching flexibility. It is also specifically designed to be suitable for future extensions and maintenance without interrupting operations. Other features include a state-of the-art digital control system, high-voltage power cables and protection equipment.

The first part of the contract, to energise two bays of the 15-bay substation, will be completed by October 2002, and the remaining circuits will be connected 12 months later.

The contract follows on from another recent substation upgrade that Alstom has carried out in the UK for National Grid. The company is close to completing the replacement of protection and control systems at the 275kV Warley substation.

Graham Johnson, Alstom T&D UK Sales Vice-President, said: “This is the first equipment of this type to be supplied to National Grid. It is designed in such a way that we’ll be able to build and commission the substation on site before decommissioning the redundant switchgear – virtually eliminating disruption and downtime. As a result, the local electrical network operators will have a more compact, flexible and expandable solution than ever before.”
