The total foreign direct investment flows into major infrastructure sectors during April-December 2011 were up 23.6 percent from a year ago.
The power sector was the biggest gainer (43.6 percent of FDI), followed by non-conventional energy (33.8 percent) and telecommunications (49.9 percent).
In order to boost economic growth in the country, the Planning Commission has projected an investment of Rs 45 lakh crore (about $1 trillion) during the Twelfth Plan (2012-17).
According to the survey, at least 50 percent of this investment will come from the private sector as against the 36 percent estimated in the Eleventh Plan. Public sector spending will also need to increase to more than Rs 22 lakh crore under the new plan period from the Eleventh Plan expenditure of Rs 13.1 lakh crore.
