#Nassau, August 28, 2019 – Bahamas – Bahamas Power and Light Company Ltd. (BPL) continues its focused efforts to return two units at the Blue Hills Power Station to service. The two units total 44 megawatts, which more than makes up the generation deficit we face during peak energy consumption hours. Together with the rest of the nation, we are keeping a close eye on Tropical Storm Dorian, since the weather could play a major role in the repair timetable for these outdoor units.
As we
reported yesterday, we are presently waiting for an additional specialist to
arrive on site and start assessments. Due to flight delays that specialist will
not arrive tonight as originally planned. As such, we don’t have an updated an
assessment to share tonight but will share what we know tomorrow after the
specialist have had adequate time onsite at BHPS.
Work on
the units had entered the testing stages after around-the-clock effort from the
local and international team in preparation for commissioning the units and
returning them to service. New, unforeseen problems have arisen with each unit
over the past 24 hours, however, and as we noted in yesterday’s update, we have
been forced to reassess our timelines. That is ongoing and will be updated in
conjunction with the new team on the ground later today.
Once
again, with the delay of the specialist, we don’t yet have any updates on the
current repair timeline. We will share an update once the specialists have
completed their assessments tomorrow and we have an update on the repair schedule.

Our
current availability is 215 megawatts against an expected day peak of 230
megawatts and an expected evening peak of 235 megawatts.
CURRENT SITUATION & REMEDIATION STEPS: We continue to work on two units at the Blue Hills Power Station (BHPS), representing the 44 megawatts of unavailable power.
Work on
the 21-megawatt 1st UNIT at BHPS continued throughout the day. The additional
specialist is expected in onsite early Thursday morning. In the meantime, the
team had to replace the head for the diesel engine, and that task was expected
to be completed over the course of the day. Once this is done, the unit can be
tested and we can assess the timeline for return to service. We have suffered
significant setbacks in the attempt to bring this unit back online, including
identification of an additional mechanical problem during recent repairs. To
properly repair the issue, we identified the additional specialist, who was due
in town Wednesday evening, but was unsuccessful in getting here today. We
believe this delay and the potential of interruption due to the impending storm
will push back our original timeline for getting this unit back online. Again,
once the specialist is on site we will be better able to determine the impact
to the timeline.
BHPS 1st UNIT: original estimated 7 to 10 days for system repair. The timeline is now being reassessed.
UPDATES: Specialist expected in Thursday morning to start assessment on Unit. ARS: Original completion date was August 30th, which is being reassessed once the specialist arrives and is on site.
The 2
ndUNIT (23-megawatts) at BHPS has developed a vibration problem, which the team
worked all day to attempt to address. Today the team attempted a mechanical
balance of the unit, a lengthy and complex process that was still going up to
press time. As this work continued, a specialist working with the team on this
unit consulted specialists abroad to try to bring even more expertise to bear
on the assessment and repair of this unit. The results of that consultation are
not yet clear, and we will update the public and our timeline once we have
accurate information.
BHPS 2nd UNIT: originally anticipated up to 21 days for system repair from last week UPDATES: Work progressed as team attempted – under the specialist’s lead – to address the new problem.
ARS: September 6th. Will be reassessed tomorrow with the arrival of the specialist.
