The overall electricity generation declined 16 per cent in May and 23 per cent in April, primarily due to the lockdown.
The plant load factor for coal-based generation in India was 48 per cent in May — a slight improvement over 42 per cent in the previous month, said the report.
While renewables grew 8 per cent and 3 per cent in April and May, respectively, coal-based power fell 33 per cent and 24 per cent, respectively.
The 2019-20 growth was 0.9 per cent — the lowest witnessed in the past two decades.
While net generation was struggling to report growth as a result of the extended monsoon and weather patterns in the last financial year, the lockdown precipitated the slowdown, said the report.
