The Ministry of New and Renewable Energy has issued a notice highlighting delays in installing Supervisory Control and Data Acquisition-based remote control systems at Indian Air Force airfields. The notice, released on December 11, 2025, follows a communication from the Indian Air Force dated November 7 and a meeting held by the Ministry on November 25. The issue concerns the requirement placed by the Ministry of Defence when issuing No-Objection Certificates for wind and solar projects. One of the key conditions is that wind turbine generators must be switched off during war, emergencies, or important operational activities if the Air Force requests it. This is necessary because wind turbines can create Doppler signals similar to those of aircraft, which may interfere with air defence radar systems by producing false targets.
To meet this requirement, developers must install a SCADA-based remote control system at specific IAF stations so that the turbines can be shut down remotely whenever needed. The Ministry has emphasised that the installation of this system should be treated as a top priority. However, it has been observed that despite several reminders during different meetings, work orders to begin the installation process have still not been issued. This lack of progress has caused concern, and the Ministry has now called for immediate action.
The notice instructs all concerned developers to move forward quickly with the implementation of the SCADA system and to submit a detailed implementation schedule to the Ministry as soon as possible. It also warns that failure to comply with these instructions or delays in submitting the required schedule could lead to the cancellation of previously granted No-Objection Certificates from the Ministry of Defence. The notice concludes by stating that it has been issued with the approval of the Competent Authority, underscoring the seriousness and urgency of the matter.
