Technical requirements: India"s sustained growth, which is projected to be around 7 per cent per annum over the next few years, poses enormous challenges with regards to energy and climate policy. With emissions of 2.3 billion tones (t) of CO2 per year (2014), electricity generation accounts for the bulk of the emissions equalling to around 30 per cent of the total. There is an urgency to improve the climate balance while meeting the increased energy demand and providing access to electricity to India"s population.
In order to curb the climate imbalance and provide uninterrupted power supply to all; the Government of India has increased the renewable energy generation target to 175 gigawatts (GW) by 2022, of which 40 GW will be generated by decentralised rooftop photovoltaic (PV) systems. The annual rate of expansion is not sufficient to achieve the target set for 2022. Despite policy and regulatory support from central and state governments, many challenges exist that affect the uptake of solar rooftop development on a large scale. Some of these are: lack of awareness among consumers, absence of innovative and attractive business and incapability of power distribution companies to promote rooftop solar PV and accommodate the business environment. Thus, the current annual rate of growth is not sufficient to achieve the target envisaged for 2022 by the Government.
The project is developing market forces while introducing enabling mechanisms and facilitating investments in rooftop PV systems. The core focus of the project is to develop the market through competition and to work systematically in selected project areas in association with the four core actors namely:
3. Municipal Corporations, licensing authorities and local enterprises in selected municipal areas (e.g. in the smart cities of Bhubaneshwar, Coimbatore, and Kochi, or in other cities) and
In the multipronged approach, the project is working on the market forces to accelerate the expansion of rooftop PV systems while designing enabling mechanisms and thus facilitating investments in rooftop PV systems. The project operates in five different activities, to achieve the objective:
The Indo-German Solar energy Partnership (IGSEP) project is commissioned by the German Government under its German Climate Technology Initiative (DKTI) is being implemented by GIZ in cooperation with the Ministry of New and Renewable Energy (MNRE), the Government of India, to facilitate and expedite the rooftop sector development in India.
The government of India is aiming for an exponential increase in the installation of Renewable Energy (RE) systems in the country including 100 GW capacity of solar power by 2022. Out of this 100 GW, 40 GW shall be capacitated by rooftop photovoltaic (PV) systems and primarily connected to the electricity distribution network (33 kV and below).
The increasing share of RE systems in the distribution grid leads to challenges for the distribution companies (Discoms). Particularly with the stringent grid codes that apply in India to operate the grid safely, it becomes even more challenging for the Discoms to handle the increasing shares of RE in the distribution systems.
Under I-RE (Integration of renewable energies in India) project, we had conducted a study "Analysis of Indian Electricity Distribution Systems for the Integration of High shares of rooftop PV." The objective of this study was to provide an overview of the characteristics of the Indian power system and its problems with regards to a large-scale rooftop PV rollout as well as to develop a template for Discoms on how to deal with rising PV shares, which studies to conduct and which technology options to select.
The State of Gujarat has four State Owned Discoms under the leadership of GUVNL which is nodal agency for implementation of solar rooftop scheme Surya Gujarat in State. The State also has 2 private Discoms operating in the city of Ahmedabad and Surat.
The State of Gujarat through it"s Surya Gujarat Scheme is heavily promoting the adoption of Distributed solar rooftop PV systems in the residential category. Gujarat Urja Vikas Nigam Limited (GUVNL) is the nodal agency responsible for implementation of this scheme. The State has a target of 3GW of distributed solar PV by the end of 2022 with current installed capacity close to 900MWp. The State has set relaxed regulations and allowed penetration of solar rooftop PV systems up to 100% capacity of the distribution transformers. With this massive adoption of solar rooftop PV systems and relaxed regulations, the distributed companies are challenged with maintaining the distribution grid while ensuring the safe and reliable supply of electricity. Under this project, we intend to develop an Accelerated PV Grid Integration Strategy for the State of Gujarat. There are following technical questions faced by Discoms:
1. Are penetration levels up to 100% RE of Distribution Transformer (DT) capacity technically possible? What is the hosting capacity of the distribution grid?
2. How can the quality of supply be ensured with penetration levels up to 100% RE with regards to e.g. overvoltage issues, harmonics, line tripping?
4. What is the best way to forecast solar generation and how to analyse and make use of this data to ensure grid stability?
The strategy shall verify the technical issues coming with a large penetration of distributed solar PV systems and provide technical and economic solutions to these challenges. With this tender under Indo-German Energy Programme - Indo-German Solar Energy Partnership (IGEN-IGSEP), this study will essentially be a case-by-case investigative analysis of the impacts of rooftop solar PV systems on distribution feeders. A representative sample of distribution feeders serving different types of areas in the licensee zone with different scenarios of loading patterns pertaining to various consumer categories is to be taken and modelled as part of the study. The detailed modelling of such feeders will be followed by power system simulation studies (supported by on-site measurements). The contractor shall develop an "Accelerated PV Grid Integration Strategy" based on this detailed study.
