GPL’s CEO, Bharat Dindyal (2nd left) and Prime Minister, Samuel Hinds, (3rd from right) witness the offloading of transmission equipment and a critical submarine cable that will enhance the current power links between East and West Demerara.

Prime Minister Samuel Hinds and Chief Executive Officer (CEO) of the Guyana Power and Light (GPL), Bharat Dindyal, were among several other top brass at the GNIC wharf yesterday to witness the offloading of several million dollars worth in equipment for the power company as part of a US$42M upgrade to the electrical system.

Media operatives on hand to witness the arrival of the equipment, which will be distributed across the grid linking several new substations, were also informed that the significant submarine cable was also a part of the cargo shipped to Guyana.

Dindyal told media operatives that four cargo vessels have been chartered to ship the equipment and apparatus to the local shores.

As part of the upgrade to the national grid, seven brand new substations are being built along with the installation of some 100 kilometers of 69KV transmission lines.

Dindyal said that yesterday’s shipment included several of the substation disconnect and earthen switches.

The submarine cable that Dindyal mentioned will facilitate the connection from West Demerara to Kingston over on the eastern bank of the Demerara River.

This cable is said to weigh over 100 tonnes. The old cable linking the Garden of Eden power facilities on the East Bank Demerara to West Demerara, has been proving a problem with complaints that it is not capable of taking more load.

GPL is also slated to receive nine power transformers and the company is now targeting mid- February for the arrival of all the equipment.

The equipment will require specialty skills and equipment to install and will also require the dredging of the Demerara river to sink it as well as ensure clearance for ocean going vessels. Dindyal indicated that the power company is working with a separate contractor to dredge the crossing. The power company is taking care to ensure the dredging takes into account future works of a similar nature, he added.

Speaking to criticisms surrounding the use of Chinese-made equipment that some have described as substandard, Dindyal stressed that, “in the specifications of this project we have used North American and European standards.”

He explained that the equipment being supplied by the Chinese have to satisfy those minimum standards imposed by the developed world and as such the equipment are not of a substandard nature.

“As you know, China has come a very far way in complying with these standards.”

He said that GPL in their specifications used the best of the North-American standards for the pieces of equipment to be supplied.

Dindyal did indicate that as it relates to standards, the power company is expecting its supervising engineers to arrive from Canada shortly after which all of the apparatus that have arrived will undergo a rigorous testing phase.

He explained that given the nature of the pieces of equipment being used, there was the possibility of them sustaining damages during shipping and as such will have to undergo testing to satisfy the international testing standards.

“Contractually they have until September next year to finish everything but their work programme is saying June they should finish,” said Dindyal when asked about the timeline that the power company is working with in relation to finishing all of the works, inclusive of testing and installation.

The Guyana Power and Light (GPL) Incorporated today received another shipment of equipment at the Guyana National Industrial Corporation (GNIC) Wharf, Lombard Street.

Speaking to the media, Chief Executive Officer, GPL, Bharrat Dindyal explained that four vessels have been chartered to bring in all the equipment for the massive infrastructural development on which the power company has embarked.

This project includes seven new sub-stations, 100 kilometres of 69 KV transmission lines, a fibre optic network, and a new control center with a state-of-the-art scanner system. On board one of the vessels too, was a submarine cable, weighing over 100 tons for the crossing from West Demerara to Kingston.

Additionally, nine power 69 KV power transformers are already on their way. The CEO noted that a lot of the equipment will be arriving between now and mid-February, by which time another vessel is expected to arrive.

With regards to the submarine cable, GPL is working with a separate contractor to dredge the crossing where the cable will be buried so as to keep it out of the way of ship anchors and also catering for the future dredging of the much-talked about deep water harbour.

When asked about the durability of the equipment which are being supplied by a Chinese firm, Dindyal explained that in the specifications of the project, North American and European construction and testing standards have been used, with which China has come a very far way in terms of compliance.

Supervising engineers from Canada will be arriving in Guyana shortly to overlook some field tests that will be done with the equipment before installing them for service, so as to determine whether there are any shipping damages.

Contractually, the Chinese Company has until September 2013 to complete the project; however, by the end of this year, most of the work will be well advanced. The West Demerara and Edinburgh sub-stations as well as the laying of the cable across the Demerara River are all expected to be completed by the end of this year.

“This project is aimed at dealing with our ability to deliver reliable power to consumers; it will improve dramatically, the quality of supply and enable us to offload almost all of our large feeders which are pretty close to their thermal limits…the new sub-stations are going to regulate voltage automatically, so the quality of supply is going to go up, the frequency of outages will reduce, quality of voltage will improve and people will see an dramatic improvement in supply” Dindyal said.

Prime Minister Samuel Hinds who is responsible for the electricity sector said that this is a step that was contemplated a long time ago when it was recognised that the country’s electricity supply system was still at a very elementary stage.

“We have grown quite a lot since then; we have improvised and making the best use we could with the resources that we have had…we still need to contemplate improving the secondary distribution system; configuring it so as to tackle the commercial losses,” the Prime Minister said.

He added that the power company has suffered its share of technical losses that resulted in a reduction of investments such as this US $42M project.

Chairman of GNIC, Glen Khan said that from the private sector standpoint, the development that is taking place in Guyana is indeed welcoming.

The project was financed under a Chinese loan amounting to US $42M which will cater for the construction of substations and improvements in the transmission lines.

The seven new substations will be constructed in Georgetown, D’urban Backlands, Diamond, Good Hope, Mahaica, Versailles, and Edinburgh. There will be upgrades to Onverwagt and Sophia, and on transmission lines from Kingston, Georgetown to Versailles, West Bank Demerara via submarine cables, Sophia to Georgetown, Sophia to Onverwagt, and overhead cables from Versailles to Edinburgh.

Last month, GPL welcomed the arrival of a new the 5.5 megawatt unit Wartsila generator for the Garden of Eden power station.
