Cogeneration CHP, Europe, On Site Power

Cogen Plant for Norwegian Oil Refinery


Norway’s Statoil is planning to build power stations at two of its facilities: a cogeneration plant at its Mongstad refinery near Bergen, and a gas-fired, power-only unit at Tjeldbergodden in mid-Norway.

The Mongstad plans call for the construction of a 280 MW CHP plant to improve the refinery’s competitive position by providing more efficient energy supplies. The new facility will supply the refinery with power and heat, as well as delivering electricity to the Troll A platform and the gas processing plant at Kollsnes, south of Mongstad. It will be fuelled with surplus gas supplied by the refinery and natural gas from Troll, which would be carried in a new pipeline from Kollsnes.

The cogeneration plant offers an energy efficiency of about 70%, with opportunities for further improvements. Overall carbon dioxide emissions at Mongstad will rise from about 1.7 million tonnes per year to 2.6 million tonnes. But the power plant will nevertheless contribute to a global reduction of more than 100,000 tonnes of emissions compared with buying electricity in the market.

The investment at Mongstad will be in the order of NOK 3 billion (US$450 million). Due for completion in 2008, the power station is being sized on the basis of the refinery’s heat requirements, which total about 350 MW. Its electrical output will be about 280 MW, or 2.2 TWh/year.


Switzerland-based Turbomach has won the 2004 Frost & Sullivan Award for Product Leadership in the European on-site power market. A pioneer in on-site power delivery, the company was conferred the award for excelling across key product performance criteria and achieving superior customer satisfaction over its competitors.

Research by Frost & Sullivan among 120 users of on-site power systems in the European Union revealed high levels of customer satisfaction with the overall performance of Turbomach’s products. The company excelled in reliability, efficiency and availability – the three critical parameters on which customers assessed the performance of on-site power providers.

The superior levels of customer approval achieved by Turbomach in the on-site power markets in Western Europe augur well for its expansion into the emerging decentralized power markets of Eastern Europe, Africa and Asia, says Frost & Sullivan. Moreover, the acquisition of Turbomach by Caterpillar is set to strengthen the company’s competitive advantage and support its ability to provide complete power generation solutions globally.
