PARIS--The French government's plan to acquire a 20% stake in Alstom SA (ALO.FR), as part of a wider deal in which the engineering group would merge its energy business with General Electric Corp. (GE), won't cost a cent to France's taxpayers, Economy Minister Arnaud Montebourg says an interview with daily Le Parisien.

Alstom's board on Saturday accepted a sweetened offer from GE for its power-equipment unit, ending a two-month fight in which Mr. Montebourg played a heavy hand to obtain employment guarantees and keep some decision centers in France.

As part of the transaction, the French government announced Saturday it would get a 20% stake in Alstom to strengthen its grip on the group, involved in nuclear activities, from its current largest shareholder, family-controlled Bouygues SA (EN.FR), and has been negotiating over the price since.

"Clearly, if there is no state entry [into Alstom's capital equity] because Mr. Bouygues doesn't want to sell his shares, the deal with GE won't take place," Mr. Montebourg says in the interview.

The French government is seeking to buy the Alstom shares at around 28 euros ($38.07) apiece, while Bouygues wants to sell at 35 euros a share.

The government has the means to acquire the stake thanks to proceeds from disposals of other stakes in companies such as Aeroports de Paris SA (ADP.FR), Airbus Group NV (AIR.FR) and Safran SA (SAF.FR), Mr. Montebourg said.

"We have around EUR2.7 billion in our coffers," he said.
