JAKARTA, Jan 6 (Reuters) - Indonesian telecommunication operator PT XL Axiata Tbk, controlled by Malaysia's Axiata Group Bhd, plans to sell 2,000-2,500 towers to repay some of its debt, a senior company executive told Reuters on Wednesday.

XL Axiata Chief Financial Officer Mohamed Adlan bin Ahmad Tajudin declined to disclose how much the company expects to raise from the telecom tower sale and the prospective buyers.

The company had said in a stock exchange filing earlier in the day that it aims to sell an undisclosed number of telecom towers through an open auction in January.

XL Axiata shares rose as much as 2.3 percent after the announcement, slightly outperforming the broader Jakarta market which was up 1.7 percent.

XL Axiata has been trying to reduce its debt burden by selling assets, replacing some U.S. dollar debt with rupiah-denominated debt and paying the more expensive loans ahead of schedule.

The company had a total debt of 29.4 trillion rupiah ($2.1 billion) as of September, according to Thomson Reuters data.

In 2014, XL Axiata sold 3,500 towers to Indonesian telecom infrastructure firm PT Solusi Tunas Pratama Tbk in a 5.6 trillion rupiah ($402.7 million) deal. (http://reut.rs/1JtkXx8) ($1 = 13,905.00 rupiah) (Editing by Subhranshu Sahu)
