MAINTAINING power grid discipline with augmenting renewable power resources emerges a major challenge before power utilities in the country. Uncertainty and variability of wind and solar generation may pose challenge in grid operation. The country is targeted to generate 100 gigawatts of solar capacity by 2022 and is planning to develop green transmission corridors with an expenditure of Rs 47,000 crore.

On the other hand, experts expressed concern over inadequate preparedness of states in the ratio of enhancing renewable energy resources in some states. The Government has already declared to double solar parks capacity upto 40,000 MWs in three years.

Western countries have developed green energy corridors in 20 years in newly developed cities but adoption of same technology in densely populated old cities in India is really a challenging task for power utilities. “All the stakeholders are working on war footing to improve monitoring of power grids along with augmenting green energy generation. Development of new 400 KV, 220 KV and 132 KV sub-stations under Green Energy Project will improve monitoring of green energy inflow into the grid. The company is working on war footing according to directions of Central Electricity Authority (CEA) and other higher authorities to enhance capacity of transmission infrastructure,” said PAR Bende, Managing Director of Madhya Pradesh Power Transmission Company Limited.

MD Bende, while talking to ‘The Hitavada’ informed that the company is working as per technical guidelines of CEA and ensuring tele-metering for better monitoring of renewable energy variations. The company is already monitoring 3,300 MWs inflow of renewable energy in the State. Preparations to strengthen transmission network under Green Energy project are underway to achieve desired task. Sources informed that discussion on different forums is being carried out while researches are underway for better monitoring of green energy inflow into grid and developing energy storage device to meet peak demand during night hours. Switching phase of enhancing renewable energy generation will be a major challenge for power utilities.

The Central and State governments have started several subsidised schemes for promotion of green energy generation through roof-top solar projects, solar energy and wind energy parks with public and private participation but monitoring of its inflow into power grid put power utilities in loggerheads.
