The utility company of the Indian state of Maharashtra, the State Electricity Distribution Company Ltd., Mumbai, placed an order with Siemens for the installation of turnkey supervisory control and data acquisition technology (SCADA/DMS) for the power distribution networks in eight cities. This EUR18.5 million order has been awarded in connection with the Restructured Accelerated Power Development Reforms Program funded by the Indian government. The SCADA/DMS systems are to be installed and ready for operation by June 2013 and are expected to improve the availability and transparency of the distribution networks and cut the related power losses by as much as 15 percent.
The contract volume for Siemens Infrastructure & Cities includes the entire project management in addition to the development, manufacture, implementation and commissioning of SCADA/DMS supervisory control centers for eight cities in the state of Maharashtra, among them the Greater Mumbai area. The order includes the installation of remote terminal units (RTU) in 66, 33, and 22 kV substations in addition to the installation of more than 4,000 compact RTU in the 11 kV distribution substations. A range of integrated IT systems, such as a customer care system and a geographic information system (GIS), ensures the fast fault elimination. Another integral part of the scope of supply is the provision of maintenance and other services for a period of five years after commissioning of the systems. "Our SCADA/DMS systems are successfully proving their worth in operation for numerous power providers and network operators in India. In network automation we are now one of the leading suppliers in that country. With the order from Maharashtra we have reinforced our position", said Jan Mrosik, CEO of the Smart Grid Division of the Siemens Infrastructure & Cities Sector.
Supervisory Control and Data Acquisition (SCADA) systems are used for the operator interface and for the control and monitoring of power networks while the combined Distribution Management System (DMS) optimizes distribution network control. Spectrum Power, the SCADA/DMS product from Siemens, gives grid operators control over the network management and the energy flow. Thanks to its Web-based architecture, Spectrum Power also allows decentralized management. Furthermore, it helps to cut the cost of network maintenance and to speed up the elimination of faults.
