THE Jamaica Public Service Company Limited (JPS) has been given until September 27 to provide a detailed report to the Office of Utilities Regulation (OUR) on Saturday’s islandwide blackout.

A release from the OUR said that,as stipulated in the Electricity Act, 2015, the light and power company is obliged to provide a report to the regulator within 30 days of the date of restoration of power.

The OUR said it will indicate the critical data and other necessary information which should be included in the detailed report on the incident. At the meeting between the OUR and the JPS on Tuesday to discuss the power provider’s preliminary report, the implications of the power outage and the way forward, the regulatory body expressed disappointment with the islandwide power outage, the frequency of such events, and the negative impact on customers.

The OUR urged the JPS to be thorough and rigorous in its investigation and analysis of the incident and requested that they outline corrective measures to safeguard against recurrences, the release said. It added that the JPS has agreed to be guided by the position outlined by the regulator regarding the conduct of its investigation.

Deputy director general of the OUR, Hopeton Heron, said: “Once we have received all the required information from the JPS, the OUR is committed to completing its review of the information as well as its own investigation of the outage, within 30 days. We recognise the significant impact that this islandwide outage has had on customers and so we are committed to exerting all efforts to ensure that we quickly and efficiently do our own analysis and make our recommendations.”

He said, too, that the OUR will be insisting on the conduct of a thorough review of the electricity system including their approach to grid planning, design, installation, operation and maintenance.

Early indications from the Jamaica Public Service (JPS) have pointed to a breakdown in its protection systems as the most likely cause of the islandwide power outage that occurred over the weekend.

While the company has said that more fulsome investigations into the issue will take time, it has confirmed that the outage was triggered during scheduled maintenance work at the Port Authority of Jamaica (PAJ) substation in Kingston.

“The scheduled work was part of ongoing system improvements being done by JPS to our power delivery (transmission and distribution) network,” Winsome Callum, director of corporate communications at the power company, said in an emailed response to The Gleaner.

Breakdown In Operating Procedures

According to Callum, initial investigations have revealed that there was a breakdown in the implementation of the established operating procedures for the work being done. This, she said, triggered a system fault that led to the outage.

“Preliminary indications are that the first level of the protection system did not operate as expected. As a result, several units at our power plants went offline. The network, in turn, shut down to protect itself from possible damage,” she said in explaining the failure on the protection system.

The protection system is a built-in mechanism on the national grid which is designed to safeguard against procedural errors.

“The protection system is designed to operate at different levels, ranging from isolating areas with a fault all the way up to the ultimate protection being to shut the entire electricity network down in the event of a major system fault,” the power company said.

The electricity supplier has indicated that in the coming days, its investigations will be focused on evaluating why the protection mechanism did not operate as expected.

The power company said it has already taken corrective measures and will be investing in system upgrades to create what it describes as a self-healing grid.

In the meantime, the Office of Utilities Regulation will today meet with executives of the JPS to discuss details of the ongoing investigations into the power outage.

The utility regulator wrote to the company yesterday requesting a preliminary report into the incident.

Callum confirmed that Energy Minister Dr Andrew Wheatley was provided with a preliminary overview on the outage and was to receive an initial report yesterday.

As investigations continue into the power outage that blanketed the entire island on Saturday evening, chief executive officer (CEO) of the Jamaica Public Service Company (JPS) Kelly Tomblin has promised to be open and transparent with the public about the findings of the probe.

“The only thing I know for sure is that the process was not followed one hundred per cent. I don’t know completely why that resulted in a system-wide outage. That is what my team is working on today, and that is what we are going to continue to talk to the press about. We have nothing to hide,” she said in an interview with The Gleaner yesterday.

Jamaica’s sole power distribution company said the outage was caused by a “procedural error, which resulted in a number of generating units going off-line simultaneously”.

In a release to the media, the electricity supplier said it has started its investigations and would provide further details on the cause of the outage today.

Minister of Science, Energy and Technology Dr Andrew Wheatley was swift in expressing displeasure with JPS because of the blackout.

“Let me categorically state that I am not at all happy with this latest incident and I find the inconvenience to the people of Jamaica and the many businesses affected totally unacceptable,” he said in a statement.

CATASTROPHIC FAILURE

Arguing that “islandwide power outages of this nature should not occur as there ought to be processes, procedures, and adequate redundancies in the grid to mitigate such a cascading set of events that would result in a catastrophic failure of this kind”, Wheatley said that he has requested that JPS submit a preliminary report on the cause of the blackout to his office today and a full report by Thursday.

Tomblin indicated that she was having numerous meetings with her technical team and was in the process of preparing a preliminary report to be submitted to Wheatley.

The JPS CEO was forthright in shedding light on the nature of the “procedural error”, which is believed to have caused the outage. She explained that the company’s technical team was still working to put together a more fulsome analysis of the outage.

“We know there was an operational error, but that does not explain something else, which will take some time to figure out. It looks as though there was a technical procedure done on the Hunts Bay station that was not completed one hundred per cent according to process, but that should not have resulted in the collapse of the system, so we have to look to see if it’s a design or engineering issue, but I don’t want to jump the gun and give inaccurate information at this stage,” she said.

In April, the country was also plunged into an islandwide power blackout. The light and power company later said that that outage was caused by problems because of work that was being done on two major power lines in the Three Miles area of Kingston.

Up to late last night, the Jamaica Public Service Company (JPS) was yet to determine what caused a “fairly widespread” power outage that left tens of thousands in darkness.

Reports of the outage began to emerge shortly after seven o’clock from Manchester, Hanover, St Mary, Kingston, St Andrew, Portland, St Catherine, Trelawny, St James, Clarendon, and Westmoreland.

The JPS issued a statement almost an hour later, from its Twitter account, advising that “the problem seems to be fairly widespread as customers in several parishes have been affected”.

It added: “We are not able at this point to say what caused the problem or how soon we’ll have everybody back on, but power has already been restored to some areas.”

Winsome Callum, director, corporate communications at JPS, later explained that “a number of generating units went offline simultaneously, resulting in a fairly widespread outage affecting customers in several parishes.

“We are not able at this point to say what caused the units to go offline or how soon we’ll have everyone back,” she added.

Callum explained that the restoration “could take a while because of the pretty involved process of ramping up units before energising the lines”.

Meanwhile, Energy Minister Dr Andrew Wheatley said he had been in contact with the Kelly Tomblin, president and chief executive of JPS, about the situation.

“I’m sure that I will be getting a report on the matter,” Wheatley told The Gleaner.

Last month, the light and power company advised that customers could experience outages between April and May as the company moves to convert its operations at the Bogue power station in St James to natural gas.
