The value chain of the Indian power sector can be divided into the power companies, the transportation sector, and the distribution sector. According to the latest estimates, the installed generation capacity of India was 3,56,100.19 MW (provisional). Accordingly, 1,75,528 MW of peak load requirement was largely met during FY 2018–19 despite a 1494 MW (0.8%) supply shortage during that period. There were a lot of power shortages in the industry until recently due to a lack of generation capacity, but that has now changed.
Throughout the next five years, the Central Electricity Authority (CEA) predicts that existing generation capacity, coupled with power projects that will be put into service during this time, will be enough to meet energy demand growth.
In the transmission sector, India’s regional networks (Northern, Eastern, Western, North-Eastern, and Southern) are currently incorporated into a single national grid. At the end of the 12th master plan (2012–2017), India’s interregional transmission capacity will be approximately 75,050 MW. India’s regional energy needs are projected to be met by roughly 1,18,050 MW by the end of the 13th Plan (2017–2022).
Network, loop, and radial systems
There are three types of distribution systems: radial, loop-based, and network-based.
Usually, all three components are combined, and this happens frequently. Radial distribution systems are the least expensive to construct, and they are commonly used in areas without much population.
As part of a radial distribution system, one power source is shared by several clients. Outages, short circuits, or downed power lines would interrupt the current power line, which would require repair before electricity could be restored.
In the event that a line fault results in a power outage, the utility needs to identify and move the fault as soon as possible. After the actual defect has been identified, it can be fixed with the least amount of disruption to the client. Loop systems cost more than radial systems because more switches and conductors are required, but the higher reliability often makes them worthwhile.
The most challenging loop systems are interconnected network systems. Several different power sources can be connected to one client at the same time. One of the major benefits of such a system is its increased reliability. However, there is a high cost associated with this. Thus, urban areas with dense populations tend to use it.
