Various assessments have shown abundant renewable energy potential
for India, especially solar. For a fully sustainable power system,
monsoon presents an obstacle with the resultant decrease in solar
resource availability. In this study, India is subdivided into 10
regions and these regions are interconnected via power lines. A 100% RE
transition pathway in hourly resolution, till 2050 is simulated. The
results from this study clearly indicate that the power system can
overcome the monsoon hurdle by solar-wind complementarity and grid
utilization. Wind energy output increases in regions thathave the best
wind conditions with 62% of the total wind energy generated in monsoon.
Solar PV and grids can manage the unavailability of wind resourcesin
some of the regions. There is a clear indication that imports increase
during the monsoon period. The least affected regions such as
India-Northwest can transmit PV electricity to other regions via
transmission grids. In the monsoon period,grid utilization increases by
1.3% from the non-monsoon period to satisfy the respective demand. The
two major exporters of electricity,India Northwest and India South
export about 43% of electricity in the monsoon period. These results
clearly indicate that no fossil based balancing is required in the
monsoon period.
