THE Office of Utilities Regulation (OUR) has given light and power company the Jamaica Public Service (JPS) until Friday to submit additional information on the islandwide power outage that occurred between Sunday and Monday, inconveniencing its over half a million customers.

The demand came yesterday after the light and power company submitted a preliminary report to the OUR on the blackout, which the JPS said was caused by a "system disturbance in the vicinity of the Duhaney substation", which "cascaded to eventually affect all customers".

"Having examined this report, the OUR, as part of its investigation, has requested from the company additional information which will assist in determining the cause of the outage as well as the integrity and security of the system," the OUR said in a release late yesterday.

The additional information will aid in determining what regulatory interventions may be required," the OUR added.
