TEMPORARY power supplier Aggreko gave investors a boost after reporting signs of a more stable picture in its troubled North American market.

The company, based in Glasgow, which has provided power for events including the Winter Olympics and the football World Cup, said the pressure on US prices caused by oversupply may be "stabilising".

The update came as Aggreko said the cost of a group-wide restructuring would cost it up to £15m in next year's results.

The outcome of the review is expected in March, although it is likely to result in some job losses as well as changes to Aggreko's depot network.

The company has 13 depots and about 400 of its 2,000 staff in the UK.
