Power distributor Umeme says at least 59 transformers have been vandalised or had their oil siphoned from August to-date, with cases not declining in spite of the lockdown.
Ms Doreen Ogenga, the Umeme Operations Manager, on Monday said there is increased theft and destruction of transformers and electricity supply infrastructure.
Transformers and other electricity supply infrastructure are public assets and it is an offense to steal or destroy them.
"Interference with the electricity supply network causes power blackouts, threatens the security of our homes, increases the cost of doing business and electricity tariffs, and disrupts vital health and education services," Ms Ogenga said.
Adding: "We therefore call upon members of the public to end this criminal activity by reporting any suspicious activities around electricity supply installations to the nearest Police Station."
