Maharashtra State Electricity Transmission Company limited, a wholly owned corporate entity under the Maharashtra Government, was incorporated under the Companies Act, in June, 2005 after restructuring the erstwhile Maharashtra State Electricity Board to transmit electricity from its point of Generation to its point of Distribution.
It owns and operates most of Maharashtra’s Electric Power Transmission System. MSETCL operates a transmission network of 43059 Circuit KM of transmission lines and 619 EHV Substations with 107369 MVA transformation capacity. This infrastructure constitutes most of the inter regional as well as intra-regional electric power transmission system in the State. Today, MSETCL is the largest state transmission utility in the country.
The company also has the distinction of being the only power utility in the state sector to own HVDC lines. The Company operates a 1504 CKM long, 3582 MVA, 500 KV bi-polar HVDC line from Chandrapur to Padghe. This has been marked as a major success as electric power is generated in east Maharashtra, due to easy availability of coal, whereas the bulk use of power is in the western part of Maharashtra in and around cities such as Mumbai, Pune and Nashik. The power losses are very low in the HVDC line. As a result, the power received at Padghe is practically the same as what is injected at Chandrapur.
The load dispatch center is the nerve centre for the operation, monitoring and control of the power system. The SLDC Kalwa near Mumbai is fully computerized and has ultra-modern facilities. Mahatransco also has a Load Dispatch center at Ambazari near Nagpur. To keep up with the increase in Power generation in the next 5 years, Mahatransco also has planned to establish a robust transmission network. It is implementing an ambitious expansion plan over the period 2011-12 to 2015-16, to meet the evacuation and grid strengthening needs of the future. The adoption of predictive maintenance practices has helped the company to reduce interruptions and improve the network’s availability to 99.73% (HVAC) & 99.30% (HVDC).
At MSETCL, thrust is given on innovation for value creation and cost optimization. It has installed ABT metering at 530 Sub-stations for energy accounting purposes and implementation of FBSM. The ERP system is fully integrated and being put into use, where functions of key departments are on line. To set up a comprehensive communication network by utilizing existing infrastructure, an Optic Fiber communication system of about 2801 Km is being installed. It has also experimented with unmanned remotely controlled substations at two locations and GIS substations at Bhandup and Hinjewadi. To raise funds from the market for equity capital/ capex schemes and to reduce its interest burden, MSETCL is readying itself for the launch of an IPO. It has undertaken an ambitious task of establishment of a 765 KV substation at Aurangabad. The State Load Dispatch Centre (SLDC) at Kalwa and Ambazari are being renovated and modernized with 140 Nos. of SCADA – RTU.
Besides continual technical up-gradation, the company lays emphasis on imbibing required skills in its people and therefore it has invested in creating training infrastructure. The Company has adopted the National Training Policy and has established fully equipped Training Centers at 7 different locations which are attached to respective Zonal offices. These centers impart training on Technical, Safety and Soft skills which are guided and monitored by the HR/Training Department. It has recently established a Technical Training Centre - the Power System Learning Centre - at Aurangabad where employees are trained on various power system protection and equipment testing. Recently the Company has bagged “Special Commendation National Award 2011” for Innovative Training Practices from the Indian Society for Training and Development, New Delhi.
