Guyana’s Power Line to Halve Electricity Bills Hits 99%

Energy

Key Facts

—The milestone. Guyana’s Gas-to-Energy transmission network, linking Wales across the Demerara River, is now 99 percent complete.

—The payoff. The project is meant to roughly halve electricity bills by replacing costly imported heavy fuel oil with natural gas.

—The plant. A new 300-megawatt power station at Wales will feed the grid, with the first turbine due online by the end of 2026.

—The build. Three new substations are far advanced, material procurement is done, and the works logged over two million injury-free man-hours.

—The timeline. All turbines are due by early 2027, with full combined-cycle operation targeted for June 2027.

Guyana has brought its most ambitious energy project to the brink of the finish line. The transmission network for its Gas-to-Energy scheme is now 99 percent complete, putting a long-promised halving of electricity bills within reach by the end of the year.

The network is the set of lines and substations that will carry power generated at Wales, on the west bank of the Demerara River, across the water and into homes, businesses and industry. It is the piece that turns a power plant into usable electricity for the country.

The update came from the head of the government’s Gas-to-Energy taskforce, in a briefing to the public information department. For a foreign reader, the significance is simple, as cheaper and more reliable power is the bottleneck standing between Guyana’s oil wealth and a broader industrial economy.

Why Gas-to-Energy matters for costs

Today the national utility burns imported heavy fuel oil to keep the lights on, an expensive and dirty way to make power. That reliance has left Guyanese consumers with some of the highest electricity rates in the region.

The new scheme swaps that fuel for natural gas piped from the offshore oil fields. The government says the switch will cut power bills by about half, a saving that would ripple through household budgets and business costs alike.

The scale of the current burden is stark. The utility has been spending tens of millions of dollars every month on imported fuel, a bill that has climbed sharply as global prices rose.

What is still left to finish

The transmission side is nearly done, but the power plant it serves is not. The 300-megawatt station at Wales is still being built, and the two elements must both be ready before electricity can flow.

Officials expect the first gas turbine to come online by the end of 2026, delivering an initial slice of the plant’s capacity. The remaining turbines are due in early 2027, with full efficiency reached the following June.

The project has a history of slipping deadlines. Ground instability and a contractor dispute pushed the original 2024 start date back by two years, adding heavily to the cost, which sharpens the significance of this near-final milestone.

The gas itself comes from offshore. Natural gas is piped from the Liza field, part of the vast oil complex operated by ExxonMobil, with about fifty million cubic feet a day feeding the Wales plant.

The first stage will not deliver the full capacity at once. Officials expect an initial simple-cycle output of around 228 megawatts before the plant reaches its complete 300-megawatt design later in the sequence.

The plant also anchors a bigger plan. A large industrial development zone is taking shape around the site at Wales, which the government wants to turn into a hub for advanced manufacturing and processing powered by cheap domestic gas.

What is Guyana’s Gas-to-Energy project?

It is a plan to bring natural gas ashore from Guyana’s offshore oil fields and burn it to generate cleaner, cheaper electricity. It pairs a pipeline and a 300-megawatt power plant at Wales with new transmission lines and substations to move the power to where it is used.

When will consumers see lower bills?

Not until the plant itself starts generating, which the government targets for the end of 2026 with a first turbine, building to full operation by mid-2027. The transmission network being ready removes one major obstacle, but the savings depend on the power station coming online as planned.

Why does this matter for Guyana’s economy?

Reliable, low-cost power is the foundation the government is counting on to turn an oil windfall into lasting industry. Cheaper electricity would make local manufacturing and processing more competitive, part of a wider bet to build an economy that outlasts the oil itself.
