In 2020, the Philippines' total non-coincidental peak demand1 reached 15,282 MW, which is 299 MW or -1.9% lower than the peak demand in 2019. This decline in demand can be greatly attributed to the effect of COVID-19 pandemic, which put the country under different levels of community quarantine beginning 15 March 2020.

The declaration of community quarantine caused huge economic losses in a number of businesses and commercial establishments, resulting in an evident slowdown in the operations of the commercial and industrial sectors. Additionally, the travel restrictions put in place by the Philippine Government across the entire country limited the movement of the people which further hindered the otherwise expected demand growth.
