Nokia announced it has provided Indian power utility Tata Power Delhi Distribution Limited (Tata Power-DDL) with an IP/MPLS network to support the management of its electrical grid in its area of operation in North and North-west Delhi.

The deployment enables Tata Power-DDL to support both mission-critical operational services as well as traditional business and IT services all on a single communications network, Nokia said.

Tata Power-DDL claims to be the first power utility in India to successfully implement teleprotection service using Line-Differential Relay (LDR) over an IP/MPLS network. This is an essential requirement for operating and maintaining a reliable, robust and safe electric grid, as teleprotection makes it possible to detect the presence of faults and trip breakers to isolate a certain section of the grid, containing the impact of the fault to a localized region.

Other mission-critical operational services supported by the new network include SCADA, integrated surveillance system, distribution management system and distribution automation, among others. The network also enables Tata Power-DDL to support emerging smart grid applications such as distributed energy resources, mobile workforce management systems and automated demand response, said Praveer Sinha, CEO and MD of Tata Power-DDL.

“The IP/MPLS network provided by Nokia will not only aid in speedier smart grid implementation but will also help in improving the reliability, scalability, security and efficiency of the power network through real time monitoring which will benefit our customers,” he said in a statement.

The network also delivers traditional business applications, including CRM, ERP and video surveillance systems.


On top of its IP/MPLS network equipment, Nokia has provided professional services including network design, installation, commissioning and integration. Nokia will also provide maintenance services and support.
