Central Electricity Authority (CEA) has highlighted the need for improved weather data in solar and wind power forecasting. Inaccurate weather forecasts often result in significant financial penalties for renewable energy generators under the Deviation Settlement Mechanism (DSM). To mitigate this and enhance grid efficiency and reliability, the CEA has developed a standardised framework for Automatic Weather Stations (AWS).
The CEA has issued comprehensive “Guidelines for Automatic Weather Stations for Solar and Wind Power Plants” that addresses the following:
All State Governments, Union Territories, Renewable Energy Implementing Agencies (REIAs), and industry associations are advised to act upon these guidelines. Additionally, REIAs are requested to incorporate the AWS requirement in future bid documents to ensure mandatory installation at project sites.
