Apollo Hospitals Group is planning to invest around Rs 2,500 crore during the 2015-18 period.
"We are looking to add another 2,000 beds and investment would be Rs 2,500 crore which will happen between 2015-18," Prathap Reddy, Founder & Chairman, Apollo Hospitals Group, said.
He said the company had almost concluded investment of Rs 1,500 crore.
"So far we did not have to borrow much as our cash flow was good and promoters have pumped in capital," Reddy said.
"But, for the next phase of investment of Rs 2,500 crore we have to look for other sources including debt," Reddy said.
"If Real Estate Investment Trust becomes a reality in India than we will not have to look for debt," Reddy said.
The trust would help raise funds without losing ownership of assets.
