Says Sumant Sinha, chairman and managing director, ReNew Power: "This tender in a landmark for several reasons because it mandates an annual capacity utilisation factor (CUF) of 80% and a monthly CUF of 70%." This CUF is much higher than the average 35% CUF in most wind-powered plants. It is also a first step towards "ensuring near-firm, assured power supply using 100% green energy." Obviously, such an arrangement will call for provision of storage by the developer. For R.K. Singh, minister of state for power and renewable energy, it was the "new beginning towards firm, schedulable, affordable round-the-clock supply through 100% renewable energy power."
