Guyana's electricity generation has climbed from 903 GWh in 2020 to 1,485 GWh in 2025, a rise that reflects the pace of the country's economic expansion. The surge in demand has prompted a wide-ranging overhaul of the national power grid, as authorities work towards a target of universal energy access by 2030. Officials say the modernisation programme is intended to ensure that new generation capacity can reach homes and businesses without the losses that have long affected the network.

Peak demand has now surpassed 200 MW, a figure that has strained a grid built for a smaller, slower-growing economy. Around 26 per cent of electricity generated in Guyana is lost before it reaches consumers, a level of leakage that engineers attribute to ageing transmission lines, outdated substations and limited monitoring capability. The losses represent a significant drain on the value of power that has already been generated, and officials have described the reduction of this figure as a precondition for the country's wider energy strategy. Without a more efficient network, additional generation capacity would struggle to translate into reliable supply for households and industry.

The most significant addition to that capacity is the Wales Gas-to-Energy Project, a 300 MW facility expected to come online in late 2026. The plant will roughly double the country's existing power generation capacity, a scale of increase that has itself created pressure to upgrade the infrastructure meant to carry that electricity onward. In early 2026 the government announced a $66 billion expansion programme aimed at upgrading the national grid and improving regional connectivity, laying the groundwork for the additional load the Wales project will bring.

Much of the practical work is being carried out through a joint effort between Guyana Power & Light and the InterEnergy Group. Their modernisation rollout includes the construction of 350 km of new transmission lines, along with the building or expansion of 16 substations across the country. The programme also involves the installation of 20,000 smart meters, intended to give operators clearer visibility of consumption patterns and to help identify losses as they occur rather than after the fact.

Alongside the investment in supply and transmission, the government has turned its attention to demand. A mandate issued in July 2026 sets a target of reducing electricity demand by 20 per cent by 2030. Officials expect this to translate into savings of 516 GWh against a generation target of 2,508 GWh for that year. The approach marks a departure from a strategy focused purely on expanding output, instead pairing new generation with an active effort to manage how much electricity is used. Smart meters and related technologies are expected to play a central role in this, allowing consumption to be tracked and managed in close to real time rather than relying solely on periodic billing data.

The scale of the investment has begun to draw interest from abroad. International engineering firms, digital grid technology providers and energy service companies are among those examining opportunities created by the modernisation programme, which spans generation, transmission and consumer-facing technology. The breadth of the work, from substation construction to smart metering, has made the sector attractive to companies operating in several of these fields at once.

The next major gathering for the industry will be the Caribbean Energy Week 2027 In-Country Launch, due to take place in Georgetown in September 2026. The event is expected to bring together investors, policymakers and utility representatives to discuss the following stages of Guyana's energy transition, including how the grid upgrades now under way will support the country's longer-term targets. For a country whose power consumption has nearly doubled within five years, the coming months are likely to determine how effectively that growth can be matched by the infrastructure meant to carry it.
