The Stopgap That Never Closed the Gap: Guyana’s Solar Billions and the Blackouts That Won’t Stop

The Stopgap That Never Closed the Gap: Guyana’s Solar Billions and the Blackouts That Won’t Stop

OPINION BY : Staff Writer  August 2026 

Solar farms were sold to the public as the fix for Guyana’s power shortfalls. Months and years after commissioning, the shortfalls are still here — and no one in government has published the numbers to explain why.

Guyana’s electricity grid failed again this month. Not in a remote hinterland outpost waiting on infrastructure that has not yet arrived, but in Linden — a town where the government has been promising a 15-megawatt solar solution for years, and where residents are now enduring rolling blackouts while they wait for it to switch on. The Linden Electricity Company confirmed the outages stem from a straightforward supply shortfall: demand has outgrown the 14.5 MW available from Bosai, the solar farms meant to close that gap remain under construction, and the government has been forced back to the negotiating table with the same bauxite company whose limits triggered the crisis in the first place.

This is not an isolated embarrassment. It is the clearest illustration yet of the question APNU parliamentarian Ganesh Mahipaul has now put to the Ministry of Public Utilities and Aviation, the Guyana Energy Agency, and Guyana Power and Light: if hundreds of millions — and in some cases billions — of taxpayer dollars have gone into solar infrastructure explicitly framed as an urgent fix for Guyana’s power reliability problems, why does the reliability problem persist?

A STOPGAP BY DESIGN, NOT YET A FIX IN PRACTICE

The solar programme was never pitched to the public as a long-horizon decarbonisation project on a fifteen-year timeline. It was pitched, repeatedly and specifically, as an immediate answer to diesel dependency, generation shortfalls, and the reliability failures that have plagued the Guyana Power and Light network and isolated hinterland systems alike.

That framing is precisely what makes the current moment so difficult to explain away. Linden’s own case makes the point without any need for interpretation: the government’s own public messaging around the Linden solar project describes it as the intended remedy for a demand surge that has now arrived before the fix did — leaving residents on rolling blackouts while the solution sits half-built.

Guyana Power and Light’s own numbers, meanwhile, show a national system running close to its edge. As of mid-August, GPL reported available generation capacity of roughly 266 megawatts against peak demand ranging between 235 and 240 megawatts — a reserve margin of about 26 megawatts on a system that has separately been described as recording its highest-ever demand reading this year. A country that has spent years and tens of billions of dollars building solar capacity should not still be operating this close to the margin. If the installed solar capacity that Mahipaul has catalogued were reliably feeding the grid at anything close to its rated output, that reserve margin should look very different.

WHAT HAS ACTUALLY BEEN SPENT

Mahipaul’s letter assembles, for the first time in one place, the individual price tags behind Guyana’s solar buildout. The figures span both hinterland stand-alone systems and the larger grid-connected GUYSOL program:

Individually, each of these numbers might be defensible. Solar infrastructure is capital-intensive, hinterland logistics are expensive, and battery storage adds real cost. Collectively, they represent a sum large enough that the public is owed more than installed-capacity press releases — it is owed operating data.

CAPACITY IS NOT THE SAME AS DELIVERY

This is the distinction Mahipaul’s letter turns on, and it is the correct one. A solar farm’s rated capacity — its megawatts or megawatt-peak figure — describes what it could theoretically generate under ideal irradiance conditions. It says nothing about actual output over a year, nothing about downtime, nothing about how much of that output ever reaches a consumer’s meter rather than being curtailed, stored, or lost.

The government’s own projections for two of the completed GUYSOL sites illustrate why the distinction matters: Onderneeming is projected to generate approximately 7,700 megawatt-hours annually, saving an estimated G$447 million a year in avoided fossil-fuel costs; Charity is projected at roughly 4,600 megawatt-hours annually, worth an estimated G$267 million.

These are meaningful numbers — if they are being realised. The government has published the projections. It has not published a single quarter of actual generation data to show whether those projections are holding, falling short, or being exceeded.

Mahipaul’s letter also raises a technical point that deserves more attention than it has received: connection to a local distribution network is not the same as export to the national interconnected grid. GUYSOL facilities connect to 13.8-kilovolt distribution networks in their respective areas, and several hinterland installations operate on isolated systems entirely separate from the Demerara-Berbice Interconnected System. A solar farm described in a press release as “connected to the grid” may in practice be feeding a small local network with no meaningful bearing on the national reliability picture that ministers invoke when defending the programme’s cost.

The public has been given capacity figures. It has not been told, facility by facility, where the electricity generated actually goes.

THE QUESTIONS THAT REMAIN UNANSWERED

Mahipaul’s demand is specific and, on its face, unobjectionable for a government that maintains its solar investments are performing as promised: publish, for every facility, the total expenditure and how it compares to the original contract price; the contractor and procurement record; monthly generation figures; diesel volumes actually displaced; realised financial savings against fossil-fuel-cost projections; battery storage performance; and operational status including downtime and maintenance history.

“Guyana cannot simply count solar panels and call that energy transformation.”

That is the crux of it. Guyana has, over several years now, been shown ribbon-cuttings, capacity announcements, and projected-savings press releases. It has not been shown a single consolidated account of what these facilities have actually produced, what they have actually saved, and what has happened when demand outpaced supply in the very communities the solar farms were built to serve.                    Linden is not a hypothetical test of that gap. It is the test, running in real time, right now.

WHY THIS MATTERS BEYOND THE BALANCE SHEET

Guyana’s oil revenues have created the fiscal space to make investments of this scale without the immediate budgetary strain such spending would once have imposed. That is precisely why the accounting standard should rise, not fall. Money that is easy to spend is not thereby immune from scrutiny — if anything, the ease of spending is the reason scrutiny becomes more necessary, not less.

A government sitting on record oil revenue has fewer excuses, not more, for leaving a reserve margin this thin, a hinterland town on rolling blackouts, and a national solar programme’s actual output undisclosed years into its rollout.

The Ministry of Public Utilities and Aviation, the Guyana Energy Agency, and Guyana Power and Light have the generation data. Smart meters, inverters, and battery management systems on modern solar installations record output automatically; this is not information that would need to be reconstructed from scratch. If the political message accompanying each commissioning — that this facility would ease the shortfall, cut diesel costs, and strengthen reliability — was accurate, the underlying data will bear that out and the disclosure costs the government nothing but the paperwork.

If it will not bear that out, Guyanese taxpayers who have funded hundreds of millions and, cumulatively, billions of dollars in solar infrastructure are entitled to know why — and who signed off on projects that did not deliver what they were sold as delivering.

The stopgap was supposed to close the gap. Linden’s blackouts this month are the clearest evidence yet that, on the government’s own timeline and its own terms, it has not. The figures exist to settle the question either way. The government’s continued silence on them is itself an answer of a kind.
