Column: India’s electrical energy scarcity erased by renewables development: Kemp

Must read


LONDON, Nov 25 (Reuters) – India’s electrical energy transmission system handed the tough post-monsoon interval this yr with far much less stress than in 2021, following a serious effort to enhance coal shares and a giant enlargement of renewable era capability.

There was no repeat of the widespread blackouts which plagued many elements of the nation in late September and early October final yr when coal-fired energy crops ran wanting gasoline and have been unable to maintain up with demand.

Grid frequency fell beneath the minimal goal of 49.9 cycles per second (Hertz) simply 5% of the time in October 2022 in contrast with 11% of the time a yr earlier, based on Grid India.

The advance in frequency management is an indication of a more healthy and extra steady community capable of meet peak hundreds extra comfortably (“Month-to-month operational efficiency report”, Grid India, Nov. 23).

The nation’s coal-fired energy mills began October with greater than 9 days of gasoline available in contrast with simply 4 days on the similar level final yr, sufficient to make sure extra have been capable of begin up when wanted.

Temperatures in northern India have been additionally barely cooler than final yr, decreasing air-conditioning and refrigeration hundreds and offsetting the impression of financial development.

The typical day by day temperature within the New Delhi neighbourhood of Palam throughout October was 0.9 levels Celsius decrease than final yr and 1.9 C decrease than the long-term seasonal common.

Chartbook: India energy era

Whole energy consumption was broadly steady at 115 billion kilowatt-hours (kWh) in October from a yr earlier.

However there was a giant improve in renewable era (+3.1 billion kWh) led by photo voltaic (+2.1 billion kWh) with smaller contributions from hydro (+0.7 billion kWh) and wind (+0.3 billion kWh).

The consequence was much less stress on coal, gasoline and diesel mills, leaving extra reserves to fulfill day by day peaks and temperature-related variations in demand.

Hydro, wind and photo voltaic equipped 25.4% of all electrical energy consumption in October, up from 22.8% twelve months earlier

Whole put in photo voltaic and wind era capability elevated to 119 Gigawatts (GW) from 103 GW over the interval.

As in China, the huge deployment of renewables is starting to gradual the expansion in demand for coal-fired era.

Thus far, the impression is marginal in India, and coal-fired era is prone to rise once more as whole hundreds proceed to develop, particularly if temperatures are nearer to seasonal norms.

However renewables are beginning to bend the curve of coal consumption for energy era and scale back the longer term trajectory.
