The Ceylon Electricity Board’s Engineers’ Association says that the low electricity demand on Sunday afternoon and the relatively low stability of solar power generation have been identified as the primary reasons for the collapse of the entire power system.
However, the association points out that this situation needs to be confirmed through a proper investigation.
The relevant statement is as follows.
“Yesterday at around 11.20 am, the entire power system in the island collapsed.
The primary reason for this has been identified as the low electricity demand on Sunday afternoon and the relatively low stability of solar power generation. However, this situation needs to be confirmed through a proper investigation.
The national power system, which was unstable due to low electricity demand and high solar power generation due to a sudden power outage at the 33 kV bus bar of the Panadura substation, became unbalanced and the automatic emergency outage management process was unable to restore the system, resulting in a power outage across the entire island.
Although the national power system came close to such a dangerous situation on several previous Sundays, a complete power outage could be prevented due to the skill of the Sri Lanka Electricity Board's system control unit.
However, it is believed that the total power outage could not be prevented due to the weak state of the national power system today.
The Sri Lanka Electricity Board and the Ministry of Energy are already working together to expedite projects related to battery storage facilities and pump storage to take necessary measures to prevent such power outages from occurring in the future.
