The renewable energy industry is growing at a fast pace with 66gw of renewable energy affiliated to the nation’s power grid. The transmission aid expected from the energy generating projects is still in doubts. There is always instability in understanding whether the transmission structure will be able to handle the flow of new irregular power generation. To overcome renewable energy transmission problem, a new plan was proposed as a part of the Green Energy Corridor project to add interstate and intrastate transmission lines to strengthen the renewable energy management centers at regional and national load dispatch centers.
Many industries are behind schedule which postponed the completion of the green corridor project. The standing committee according to Mercom stated that they are sure that Green Corridor plan is achievable. The target of 8500 ckt-kms transmission lines is expected to be installed by March 2020 for the Green Energy Corridor. In September 2017 Power Grid Corporation of India filed a petition to prevent underutilization of energy by renewable energy company asking the Central Electricity Regulatory Commission to mediate the issue. The renewable energy companies instead urged PGCIL to strengthen interstate transmissions by 2020.
The transmission infrastructures are yet to accommodate 175 GW of energy generation that is expected in 2022. Grid infrastructures have to be strengthened because it is an ideal time to conserve non-renewable resources like fossil fuels to be less dependent on the imports. Digitalization of the power grid will improve transparency and create a smart system. The infrastructure would drastically change the electricity system by improving energy security. Fifteen percent of India’s population still doesn’t have access to electricity. SAUBHAGYA program by the Indian government estimates that 212,925,998 households have received electricity. The diverse geographical condition in India makes it difficult to implement a plan consistently. Micro and Mini grid could solve the transmission problem, but it would take years to reach all the remote places. Considering the cost of setup, massive investment is required to set up and maintain the system. The region must generate a significant amount of revenue to recover the investment. Mini-grids will provide remote places with sustainable energy, and if proper subsidies are provided, states can overcome the energy transmission issues.
