Guyana submarine cable suffers an anchor damage

The Guyana submarine cable has been severed by a ship, causing power outage in capital city Georgetown and leaving thousands of people with intermittent blackouts. Orient Cable’s team is heading towards Guyana to resolve the issue.

The outages caused by the failure are exerting further pressure on the generating system. Guyana Power and Light (GPL, the region's electricity providor) and the government have been under immense pressure due to the blackouts, with Christmas approaching.

Therefore, the government has contacted the Chinese embassy for support, asking for Orient Cable’s 24/7 engineering and O&M services. Orient Cable’s team is heading towards Guyana to resolve the issue.

The 69 kV cable was previously damaged by a ship in June 2019. The repair works were carried out by China National Machinery Import & Export Corporation (CMC), the company that laid the cable in 2012. The repair works were delayed due to the discovery of another damage in August that needed more time for testing and diagnosis. The cable was restored on 26 October 2019.

According to GPL, a number of measures have been taken to prevent prolonged service interruptions in an event of cable failure. These measures include: installation of a new 13.8kV Submarine Cable from Vreed-en-Hoop to Princes Street, a new express feeder from Vreed-en-Hoop to Vriesland, and additional generating capacity in Berbice to make that area more self-sufficient

Despite these efforts, the risk of short term losses has increased due to the recent failure. These risks can be further addressed by GPL’s medium term plans that include installation of an additional 10 MW generating capacity by 15 December 2020 and construction of the new 46.5MW at Garden-of-Eden by April 2021.

The 14 MW HVAC runs in Demerara river, between Vreed-en-Hoop and Kingston power plants. It first came online in 2012.
