The National Institute of Solar Energy (NISE) and Grid Controller of India Limited (GRID-India) have signed a memorandum of understanding (MoU) to jointly undertake a research project focused on hybrid day-ahead and intra-day solar forecasting for large solar parks in India.
The MoU was signed by Prof. Mohammad Rihan, Director General of NISE, and Manoj Kumar Agrawal, Executive Director, National Load Despatch Centre (NLDC), in the presence of Samir Chandra Saxena, CMD, GRID-India, along with senior officials from both organisations.
The collaborative initiative will be implemented in partnership with leading renewable energy developers, including Adani Green Energy Ltd., NTPC Green Energy Limited, Tata Power Renewable Energy Limited, ReNew, and Serentica Renewables. These companies will provide access to large utility-scale solar parks for real-time deployment and validation of the forecasting system.
Under the project, the partners will develop a next-generation hybrid solar forecasting framework that integrates numerical weather prediction (NWP), satellite data, and real-time All-Sky Imager (ASI)-based nowcasting. The system aims to generate high-frequency probabilistic forecasts, such as P50 and P90, ranging from a few minutes up to 48 hours.
The initiative is expected to enhance short-term predictability of solar generation, reduce risks associated with the Deviation Settlement Mechanism (DSM), and improve scheduling reliability for both developers and system operators.
The MoU marks a step toward building indigenous, data-driven capabilities to support large-scale renewable energy integration into India’s power grid.
