According to a Tangedco release, the Manali substation (400/230 KV) is a key power hub supplying electricity to large parts of Chennai. Typically, the Alamathi substation (400 KV) and the North Chennai Thermal Power Station II (NCTPS) are the primary power sources for the Manali substation, which in turn supplies 800 to 900 MW to major substations in Chennai, including Pulianthope, Tondiarpet, Mylapore, RA Puram, Basin Bridge, Vyasarpady and Sembiyam.
