International Business

In order to give thrust to International Business, a separate International Business Department was spun off from Business Development Department in December, 2008.

The objective of International Business is to continually leverage its capabilities with its USP of “Utility-turned Consultants” to generate superior value to its Clients and Stakeholders and hence become the most preferred Service Provider globally, to set superior global standards, to gear up for next competitive phase and to learn international best practices, replicate the International learning experience for the benefit of domestic projects and successfully contribute to overall POWERGRID revenues.

POWERGRID- Global Consultant


Based on the rich experience earned through implementation of huge Transmission networks in India and abroad and by adopting latest technology in multifarious topology and environment, POWERGRID has emerged as a renowned Consultant in Power Sector globally.

POWERGRID’s skill set has been sharpened by project execution experience in extreme conditions both natural and man-made. In spite of all odds, POWERGRID has managed to take up the assignments successfully and implement them successfully within given time-frame.

As POWERGRID is a Utility turned Consultant, the feedback obtained while carrying out the Operation & Maintenance of its projects is ploughed back to its design departments for continual improvement. These point of difference put POWERGRID as the much preferred Consultant to bring in world class solution to its Clients.
