EDMONTON - The New Democrats want the Alberta government to force a company that manipulated electricity imports to reimburse consumers.

TransAlta Corp. (TSX:TA) has admitted it restricted imports of cheaper electricity last November, which drove prices up.

The Industrial Power Consumers Association of Alberta estimates that TransAlta's conduct cost Albertans an extra $4 million on their power bills.

The corporation and Alberta's electricity market watchdog are proposing that TransAlta should pay $370,000 in penalties.

NDP Leader Brian Mason says Albertans deserve to be paid back in full.

Mason says people depend on affordable electricity and he's called on the government to step up regulation of the power market.
