Chennai's infrastructure supports its status as a leading metropolis:
* **Electricity:** Supplied by the Tamil Nadu Generation and Distribution Corporation (TANGEDCO). Power cuts are rare compared to previous decades. * **Water & Sewer:** Managed by the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB). The city historically struggles with water scarcity and relies on monsoon-fed reservoirs, piped water from the Krishna River, and two major seawater desalination plants (at Minjur and Nemmeli) to meet demand. * **Telecommunications:** Excellent broadband and cellular connectivity (4G/5G) is provided by major telecom operators like Jio, Airtel, and BSNL. Chennai serves as a landing point for multiple international submarine communications cables, ensuring high-speed internet availability.
