Total demand met hit a record 140 billion kilowatt-hours (kWh) in June, up from 134 billion kWh in June 2022. Chartbook: India's electricity systemGrid controllers have been able to call on much more generation from renewable sources and improved availability of fossil-fuel units. Generation from wind farms increased by 1.5 billion kWh (+16%) while solar output was up by 1.1 billion kWh (+14%) compared with the same month in 2022. Other generation, mostly from coal-fired units, also increased by 3.3 billion kWh (+3%) owing to improved fuel availability.

At the same time, extra generation was provided by solar farms (+1.8 billion kWh, or +23%) and coal-fired generators (+0.3 billion kWh, or +0.2%). These increases helped offset some of the reduced output from hydroelectric generators (-3.0 billion kWh, or -25%) and gas-fired units (-0.3 billion kWh, or -10%). Chartbook: India electricity systemThe combination of lower temperatures and increased solar generation significantly reduced stress on the transmission system, especially during the afternoon peak. Combined with lower temperatures and lower generation, the increase in coal deliveries was sufficient to rebuild generator inventories to a more comfortable level and avoid previous fuel problems.

LONDON, March 29 (Reuters) - India’s electricity transmission system is coming under increasing strain as booming power demand outstrips growth in despatchable generation. Peak demand met was up by 8% compared with a year ago and 11% compared with 2021 (“Monthly report”, Grid India, March 23, 2023). Frequency is related to the balance between generation and load - excess generation causes frequency to accelerate, excess load causes frequency to drop. The increasing incidence of under-frequency shows controllers struggled to schedule enough firm generation to meet increasing demand on the system. Peak electricity demand in January (210,618 megawatts) and February (209,665 megawatts) was only slightly lower than at the height of last summer in June 2022 (211,856 megawatts).

April nighttime peak demand is expected to hit 217 gigawatts (GW), up 6.4% on the highest nighttime levels recorded in April last year. "Even the smallest interruption in power supply will create havoc," Nair said. As much as 189.2 GW of coal-fired capacity is expected to be available this April, according to Grid-India's February note. The strain comes after sundown, as coal-fired capacity has grown only 9% over the last five years. Hydro and nuclear power capacity additions face tougher obstacles, as they are hobbled by lack of foreign investment and opposition from critics over safety and environmental issues, boding ill for power supply down the track.
