Global power transmission and distribution sector (T&D) grew at a CAGR of 13.7% during 2006–2014, due to strong growth from Asia, America and the Middle East and Africa. The outlook for the T&D sector is expected to be bright, owing to the mounting power demand from Asian and African regions because of favorable demographics, increasing demand for clean energy, cross-border power networks (especially in Europe and Africa) and underdeveloped transmission systems across these areas.

The Indian government is planning to invest extensively in the domestic electricity network, which is part of its plan to provide electricity to all households. In June 2014, the government announced a plan to provide electricity access and reliable supply to all households. The transmission and distribution sector is expected to receive an investment of nearly US$44.6 billion by 2019, of which US$14.8 billion was supported by the government through the Deen Dayal Upadhyay Gram Jyoti Yojana and Integrated Power Development schemes.

Furthermore, the Green Corridors project – which involves an alternate transmission network for renewable energy – is being revised with the plan to add 100GW of solar power and 70GW of wind power by 2022, which required an investment of US$6.4 billion (INR430 billion) to cover intra/inter-state transmission system strengthening by 2020. In FY2016, the Power Grid Corp board approved investment of USD74.3 billion in three phases for a green energy-corridor inter-state transmission scheme (ISTS).
