Currently India is in the process of converting their power system towards higher shares of renewables. Grid stabilization tasks, formerly exclusively carried out by very large power plants, will in the future have to be obtained by renewables as well. Since retrofitting is usually complicated and cost intensive, the foundation for save grid integration of variable renewable energies must be laid out today. In this regard India can immensely profit from the experience gained in countries with already high shares renewables to avoid making the same mistakes. Therefore the objective of this paper is to give recommendations on the current Indian Grid Code framework, to include renewable power plants in grid stabilization schemes (Ancillary Services) based on international best practices. These are based on results of a GIZ funded project, where the possibilities to control active power and the provision of ancillary services with renewable energies in South India were compared with several international experiences. A provision of Ancillary Services (AS) is especially important in India since the majority of conventional power plants operate under Power Purchase Agreements (PPA). These usually do not include Ancillary Service measures. With a rise of volatile renewable energy generation the need for Ancillary Services increases as well. As a consequence these plants will have to provide Ancillary Services themselves, even though provision of AS often is cheaper with conventional generation (fuel cost savings), if not restricted by PPA's. One of the main recommendation is to include all power plants connected to the medium voltage grid and above into the Indian requirements currently set up only for large generators. In the future all generators (except low voltage level) should be remotely controllable, to adjust setpoints and have all operation relevant variables available at the grid operator level. Further, new plants should be capable of automatic frequency and voltage control. Only with these requirements in place fitting market structures for Ancillary Service provision via renewable energies can be effective. Currently Indias Energy Market is not well advanced and several steps need to be taken before a robust AS-market scheme can be put in place. Therefore, both market and technical capabilites have to mature simultaneously in order to be ready once safe grid operation, without Ancillary Services provided by renewable energies, is no longer possible.
