The worry seems to have been sparked by a newspaper article which suggested that the disposal of PacifiCorp to Warren Buffett's MidAmerican Energy Holdings has attracted the wrath of a US watchdog. The news pushed ScottishPower shares down 8.5p to 537p.
Under Oregon state law, any company wanting to buy a local utility must first prove to regulators that the transaction is in the public interest, and that the deal will result in a "net benefit" to customers.
According to the article, staff at the Oregon Public Utility Commission had criticised the PacifiCorp deal at a public hearing, arguing that the sale of the business to MidAmerican Energy fails to satisfy regulatory requirements.
Nevertheless, towards the end ofyesterday's session, ScottishPower stock recovered some of its losses - at one point during the day its shares touched a low of 525.5p - as the company pointed out that the comments from the regulator came during the first of many public hearings on the matter.
A spokesperson for ScottishPower stressed: "This is the first public hearing in a process that will run until early next year." Analysts suggested it is unlikely the sale of PacifiCorp will be delayed by the Oregon regulator.
