Guyana’s rapidly expanding economy and rising electricity consumption are placing growing pressure on the country’s power distribution network, with overloaded lines and transformers emerging as major contributors to recurring power interruptions.
The challenge is no longer simply about generating enough electricity. The existing grid’s ability to safely transmit and distribute that power has become a critical concern, particularly in densely populated coastal areas.
Minister of Public Utilities and Aviation Deodat Indar recently highlighted the issue, explaining that sections of the transmission and distribution network are operating beyond the design capacity for which they were originally built.
The situation is particularly evident on the 13.8 kV distribution network. In some locations, lines designed to handle about 8 megawatts now carry loads of around 10.1 megawatts. Rapid residential development, expanding commercial activity and increased electricity consumption have contributed to the growing imbalance between demand and available network capacity.
When electrical conductors operate above their intended capacity for extended periods, temperatures rise. Continuous overheating can stress transformers, connections, and insulation, increasing the risk of equipment damage and premature failure.
Recent transformer fires and repeated feeder trips have highlighted the consequences of this pressure. In affected communities, customers may experience prolonged outages while crews work to identify faults, isolate damaged equipment and restore electricity.
Demand is rising faster than the network can keep up.
Guyana Power and Light Inc. (GPL) has indicated that several outages are linked to strain on the distribution system, particularly during periods of high residential consumption.
Evening demand places significant pressure on feeders and transformers. Where necessary, GPL has redistributed loads between feeders or temporarily taken sections of the network offline to prevent more serious failures.
GPL Deputy Chief Executive Officer Bharat Harjohn said the company is continuously examining feeder demand and identifying opportunities to redistribute electricity between nearby circuits. However, he noted that available network capacity limits the ability to shift loads.
Other factors can also contribute to interruptions. Construction work, heavy vehicles coming into contact with electrical infrastructure, illegal connections and unsafe wiring can cause feeders to trip, thereby affecting voltage stability.
Peak demand reaches new levels.
Recent figures from an Inter Energy assessment of Guyana’s electricity system illustrate the scale of the challenge.
President Dr Irfaan Ali said peak demand on the Demerara-Berbice Interconnected System rose from roughly 205 megawatts in 2024 to 242.6 megawatts in August 2026. This represents an increase of about 18 per cent over a relatively short period.
The pace of demand growth is considerably higher than the average annual growth across many electricity systems in Latin America and the Caribbean.
Several factors are driving the increase, including new housing developments, expanding industries, hotel construction, and wider economic activity.
At the same time, GPL is expected to connect more than 62,000 additional customers, further straining infrastructure that is already operating close to its limits.
The Inter Energy assessment projects that electricity demand could increase by approximately 138 per cent by 2029. Such growth would require a major expansion of generation, transmission and distribution capacity.
President Ali has also highlighted the limited flexibility within parts of the network to take generating or transmission assets offline for routine maintenance. In areas where capacity is already heavily utilised, the failure or removal of a major component can pose wider reliability risks.
Large-scale investment underway
The Government is pursuing a major programme to strengthen the national electricity network, alongside the Gas-to-Energy project.
More than 360 kilometres of new high-voltage transmission infrastructure are being developed to improve electricity transmission across the Demerara-Berbice Interconnected System.
The programme also includes more than 10 new substations, upgrades to four existing substations, and the deployment of two mobile substations.
Expanding the 230 kV transmission network is another key part of the programme, including about 155 kilometres of new double-circuit transmission lines.
Additional investment is being made in the 69 kV network, including a 2.5-kilometre underground river crossing between Greenfield and Kingston.
The Gas-to-Energy project is expected to add substantial generation capacity, but officials acknowledge that the transmission and distribution systems must be upgraded to match the new generation.
The Inter Energy assessment has called for a comprehensive approach to strengthening the electricity sector rather than relying on isolated upgrades.
Among the recommendations is establishing an independent grid-reliability task force focused on system performance, outage trends, technical standards, and long-term resilience.
The objective is to ensure infrastructure expansion keeps pace with Guyana’s rapidly changing electricity needs.
Meanwhile, the Government is working to manage GPL’s financial pressures. President Dr Ali said Finance Minister Dr Ashni Singh is seeking additional funding to help the utility absorb rising fuel costs and mitigate the impact on consumers.
Guyana’s electricity challenge is therefore unfolding on two fronts: expanding generation to meet rapidly growing demand and upgrading the network to deliver electricity safely and reliably.
With demand continuing to rise, the success of the country’s energy transformation will depend not only on how much electricity Guyana can produce, but also on whether its transmission and distribution infrastructure can keep pace with economic and population growth.
