The entire project is to be completed within three months from the date of issue of the purchase order.

Phasor Measurement Units play an important role in modern power systems by providing synchronized real-time measurements of electrical parameters across the transmission network. Their deployment improves grid visibility, enables faster fault detection, supports system stability, and enhances overall operational efficiency. With the installation of PMUs at Bhadla Solar Park Phase-II, RSDCL aims to strengthen the monitoring capabilities of its transmission network and ensure reliable evacuation of renewable energy. The initiative reflects the company’s continued focus on upgrading grid infrastructure to support the growing integration of renewable energy and improve the performance of one of India’s largest solar power parks.
