Grid managers seamlessly handle 32GW fall and rise in demand within 20 minutes on Sunday

Engineers at electricity load despatch centres managed a total power demand dip of almost 32 GW between 8.49 PM and 9.09 PM, on Sunday, nearly three times the estimated fall by the national power grid. Power demand fell as citizens responded to Prime Minister, Narendra Modi’s call of switching off lights and lighting candles to express their support for the battle against COVID-19 pandemic.

Just as citizens started switching lights back on, power consumption started rising. Power minister, RK Singh, tweeted: “Demand in the grid came down by 32000 MW within a few minutes but the frequency and voltage were maintained within the normal range. Demand went down from 1,17,300 Megawatts at 20:49 hrs to 85300 Megawatts till 21:09 hrs; Then it started increasing. Frequency was maintained within a band of 49.7 to 50. 26 Hz, which means the voltage was kept stable.”

“The national grid operator POSOCO and the national, regional and state load despatch centres did a great job with support from all generators; NHPC, NEEPCO, THDC, SJVNL, BBMB, NTPC, all state gencos and IPPs, transcos and distribution companies and their officers and staff. Congratulations to all of you. The national power system works as a team. India stands together with the Prime Minister,” he said in his tweet.

Almost 26 GW demand dropped between 9 PM and 9.10 PM on Sunday. Around 16.6 GW of power demand dropped between 9 PM and 9.05 PM. In the next five minutes another 9 GW power demand dropped, taking the total fall between 9 PM and 9.10 PM to almost 26 GW.
