Generator firm Aggreko said potential demand for major power projects from governments and miners has hit a record high to lift its shares on the London market.
The FTSE 100 stock surged 6% as the Glasgow-based group said its power projects arm - which builds and runs temporary power plants - has quoted on a record level of contracts over the past six months, although these are yet to translate into firm deals.
Aggreko said revenues fell 6% in the July to September quarter in the absence of last year's London Olympics boost - when it powered 39 Games venues - although were up slightly on an underlying basis.
Its power projects arm runs contracts such as powering an iron ore mine in Australia for BHP Billiton and supplying energy to German army camps in Kosovo.
Underlying sales in the division dipped 2%, with order intake roughly level with a year ago, despite a 50 mega watt (MW) contract to keep the lights on in Guinea's capital Conakry, which had been hit by power cuts.
But revenues in its local business, which rents equipment ranging from small generators to large industrial cooling towers, grew 4% on an underlying basis, lifted by near 10% growth in the Americas.
Across the group, sales in its Australia and Asia Pacific region slumped 17%, as contracts end in Japan and Indonesia.
But sales grew 6% in the Americas and 8% in its Europe, Middle East and Africa region, lifted by 430 MW of gas contracts in Mozambique and Cote d'Ivoire.
Aggreko has suffered over the past year as the absence of the Olympics, the withdrawal of US troops from Afghanistan and the tough global economy weigh on its business.
Aggreko said it is on course to meet earnings expectations for 2013, although analysts at Investec Securities plan to drop their pre-tax profits forecast by about £10 million to £330 million due to the strength of sterling.
That would compare with profits of £365 million a year earlier.
Investec analysts said: "Whilst there are likely to be further currency-related forecast downgrades, the underlying message is largely unchanged.
"The local b usiness continues to perform well against some tough comparisons and p ower projects needs new customers to sign on the dotted line."
