It is incorporated under the Companies Act, in June, 2005 after restructuring the erstwhile Maharashtra State Electricity Board (MSEB) to transmit electricity from point of Generation to point of Distribution.There are total 9 (nine) existing transmission companies in the State of Maharashtra are shown in Figure 0-1. Figure 0-1. Transmission Companies in Maharashtra. The MSETCL also functions as a State Transmission Utility (STU) and bears responsibilities to plan, develop, operate and maintain the Transmission System to facilitate transmission of electricity from its source to load centers in a secure, reliable and economic manner. As on March 2017, MSETCL owns and operates most of Maharashtra’s Electric Power Transmission System. MSETCL operates 648 Extra High Voltage (EHV) Substations, transmission network of 44,615 ckm and transformation capacity of 1,18,487 MVA at various voltage levels. Today, MSETCL is the largest STU in India. 3 | P a g e STU FIVE YEAR TRANSMISSION PLAN 2017-18 TO 2022-23 EXISTING MAHARASHTRA NETWORK AS ON 31-03-2017 Voltage EHV Substation Transformation Capacity EHV LINES (CKT KM.)
