World blackouts may grow as investment stalls

Blackouts could get more frequent as utilities fail to attract investment needed to secure future power supplies, according to a global survey by PricewaterhouseCoopers.

Seventy two percent of utility bosses surveyed said supply security was a major concern, up from 65 percent in a similar poll last year, PwC said on Monday.

More than a third of investors polled said uncertainty over regulation and inconsistent government policies were damaging confidence in the utilities sector.
