Under the current national target based on National Solar Mission, 40 GW of rooftop PV shall be connected in India by 2022. To reach this target, a good understanding of the Indian power system, its regulatory frameworks, and the similarities and differences with other countries that have already deployed a large share of rooftop PV has to be developed by all stakeholders involved in the process.

Under the Indo-German technical cooperation, Government of Germany is cooperating with India and has commissioned a project “Integration of Renewable Energies in the Indian Electricity System (I-RE)” through the International Climate Initiative of the German Government. The project is financed by Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) and implemented by Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) in partnership with Ministry of New and Renewable Energy (MNRE). 

Considering the need for extensive capacity building in India, GIZ has commissioned Energynautics to conduct this study on the integration of rooftop solar PV into Indian distribution grids at the voltage levels of 33, 11 and 0.4 kV. Starting out with a desktop study on the characteristics and peculiarities of the Indian power system and its regulatory framework, and a comparison to other countries where PV integration has already progressed further, the scope of the study also includes detailed modelling and simulation of four different distribution grid feeders in Delhi and Bhopal. Data for the simulations were kindly provided by the local distribution companies, BSES Rajdhani Power Limited (BRPL), Delhi and Madhya Pradesh Madhya Kshetra Vidyut Vitaran Company Limited (MPMKVVCL), Bhopal.

The study intends to provide an overview of the characteristics of the Indian power system and its problems with regard to a large scale rooftop PV rollout, as well as a template for distribution companies on how to deal with rising PV shares, which studies to conduct and which technology options to select.
