India burns more coal for power as dry weather sparks blackout fears
04 Sep 2023
Driest August in more than a
century sends power generation surging to a record 162.7 billion kilowatt
hours.
It is unusual
for India’s electricity use to spike in August, when temperatures are lower due
to the annual monsoon that runs between June and September. Demand typically
peaks in May, when Indians crank up air-conditioners to beat the heat and
industries operate without rain-related disruptions.
However, the driest
August in more than a century has resulted in power generation surging to a
record 162.7 billion kilowatt hours (units), an analysis by the Reuters news
agency of data from the federal grid operator Grid India showed.
Coal’s share in
power output rose to 66.7 percent in August – the highest for the month in six
years, according to a Reuters analysis of government data. Lower rainfall led
to the share of hydropower in overall output plunging to 14.8 percent, compared
with 18.1 percent in the same period last year.
The government
has repeatedly defended the use of coal, citing lower per capita emissions
compared with richer nations and rising renewable energy output.
Despite higher
demand for coal, power plants have slashed imports by 24 percent to 17.85
million metric tonnes during the first four months of the fiscal year ending in
March 2024, government data showed, due to a 10.7 percent increase in
production by the state-run Coal India.
Lower imports
by the world’s second-largest importer of the polluting fuel behind China have
kept global thermal coal prices depressed in recent months.
Analysts and
industry officials attribute the higher power use to farmers using more
electricity to irrigate fields due to insufficient rain, intermittency of
renewables, and increased cooling demand with warmer-than-usual temperatures.
“Given the
already stressed supply situation, as poor monsoon in August resulted in high
agricultural demand, the sudden fall of wind generation … has further
aggravated the situation,” power analytics firm EMA Solutions said in a
LinkedIn post on Thursday.
India’s peak
demand – the maximum capacity required during any time of the day – rose to a
record 243.9 gigawatts (GW) on August 31, the Grid India data showed, exceeding
available capacity by 7.3 GW.
Electricity supply fell
short of demand by 780 million units in August, the data showed, marking the
highest shortage since April 2022, when India faced its worst power cuts in six
and a half years.
Weather
officials expect country-wide rainfall in September to be in line with the
long-term average, possibly providing some respite to utility operators.
Coal’s share in
output rose to 74.2 percent in the eight months that ended in August, the Grid
India data showed, compared with 72.9 percent in the same period last year and
on track for a third consecutive annual increase. The share of hydro fell from
10.9 percent to 9.2 percent.
Overall power
generation has risen by more than 108 billion units this year, dwarfing an
increase of about 16 billion units in renewable generation.
India failed to
achieve a target to install 175 GW in renewable energy by 2022 and has since
said it would try to boost non-fossil capacity – solar and wind energy, nuclear
and hydropower, and bio-power – to 500 GW by 2030.
Achieving that
target would require more than 43 GW more of non-fossil capacity every year,
nearly three times the average non-fossil capacity addition over the last two
years to July.
