BUENOS AIRES--Argentina's government will withdraw subsidies used to keep electricity prices cheap if provincial governors raise utility rates in their districts, Planning Minister Julio De Vido said Wednesday.

Mr. De Vido made the comments after local media reported that Buenos Aires Province Gov. Daniel Scioli has authorized power distributors in the province to raise rates.

"It's a question of justice or fairness: If we don't cut electric generation subsidies to the same degree that provinces raise their rates, we would be discriminating against those governments that support the social inclusion and competitiveness policies we're pursuing at the national level," Mr. De Vido said in a statement.

Mr. De Vido made his comments in response to a decision by Buenos Aires Province to authorize rate increases of up to 28% for power distributors, according to the statement.

Mr. De Vido said it was not in the government's interest to limit the powers of provincial governors to set rates. Instead, he said, the government is warning them that raising rates would distance them from the national government's policy priorities.

Spokesmen for the province could not confirm if Mr. Scioli has decided to raise rates. Meanwhile, officials at distribution companies said they weren't aware of any formal authorization to raise prices.

Whatever the case, power distributors in and around the capital of Buenos Aires are in dire financial shape, thanks to a cocktail of frozen rates and rapidly rising operating costs.

After years of inflation, which economists say likely totals around 25% annually, and a decade of capped rates, ailing electric utilities are on the brink of financial collapse.

Argentina's top power companies are Edenor (EDN, EDN.BA); Edesur, a unit of Italy's Enel SpA (ENEL.MI); and Edelap.

They distribute electricity to millions of people in Buenos Aires City and nearby cities.

Unlike distributors in Argentina's interior that have been allowed to increase rates, the three companies have been largely unable to raise rates to compensate for inflation and annual wage increases that often exceed 20%.

In 2011, Edenor, the biggest distributor, reported a loss of 435.4 million pesos ($98.3 million), while Edesur posted a loss of ARS461 million and Edelap, ARS138 million. Operating costs last year rose 42% for Edenor, about 45% for Edesur, and 18% for Edelap.

Shares of the power generation company, Pampa Energia SA (PAM, PAMP.BA), which owns Edenor, rose 1.7% to ARS1.19.
