Power producer Dominion to buy Questar for $4.4 bln
Power producer Dominion Resources said it would buy natural gas distributor Questar for about $4.4 billion in cash to expand its natural gas operations.

Dominion's $25-per-share offer represents a premium of nearly 23 percent to Questar's Friday close.

Weakening power demand due to increased energy efficiency has spurred a spate of deals between utilities and natural gas distributors, which enjoy relatively stable pricing thanks to a glut of supply from shale fields.
