In May 2018, spot power price spiked to ₹4.67 (~$0.0695)/kWh. May’s spot power price was ₹1.76 (~$0.0262)/kWh higher than the spot price recorded in May 2017, registering an increase of 60 percent from the same month last year. This is a result of an all India peak demand touching 170.9 GW in May 2018, about 6.2 percent more than the highest peak demand of 161 GW in May 2017, per National Load Despatch Centre (NLDC).
According to the Indian Energy Exchange (IEX), the reasons behind the high spot prices were: peak summer season leading to an increase in demand from the distribution companies (DISCOMs), inadequate availability of coal, low hydro generation, and a slow pickup of wind power generation in the southern and western states of India.
This also goes on to show that solar power generation which accounted for 2 percent in FY 2017-18 is still not high enough to make a difference.
The spot power prices have been undergoing a gradual increase in the country. The average spot power price recorded in April 2018 was also up by approximately 44 percent when compared to the average spot price recorded in April 2017. In April 2018, the spot power price was ₹3.98 (~$0.0594)/kWh, ₹1.21 (~$0.0180)/kWh more than the ₹2.77 (~$0.0413)/kWh recorded in the same month the previous year.
