There are two key lessons that need to be drawn from this successful "ultra mega" experience. First, it helps to think big. The larger the project, the lower is the effort per Mw required to push it through. It is therefore better to work on a 4,000 Mw project rather than a 500 mw one, especially when the same 50-odd clearances will be needed for either project. In any case, with a huge demand-supply gap to be plugged in all key infrastructure sectors, no one can afford the indulgence of managing by tweaking policy at the corners. Instead, bold steps are required. Secondly, the government needs to work on "pre-cooking" more infrastructure projects, so that some basic work on greenfield projects is done before they are offered to private investors. The UMPPs, for instance, were housed in shell companies floated under the public sector umbrella. These special purpose vehicles piloted the preliminary work on clearances and supply linkages, and also signed provisional power purchase agreements with the buyers of power. This pre-cooking effort needs to be expanded in the power sector, as well as in other infrastructure sectors, so that a shelf of bankable projects is ready for picking. Otherwise, the $500 billion investment that is required to fix the country's infrastructure gap over the next five years may never materialise.
