Guyana Power Demand 2030

Abstract or executive overview

Guyana has moved from a historically constrained electricity system into a period where load growth, industrial policy and grid expansion are interacting at the same time. The most recent public evidence places DBIS peak demand at about 257 MW in early September 2026, up from 221 MW in 2025. GPL reported 242.6 MW in August and projected 266 MW by the end of October 2026. The near-term surge reflects new connections, commercial and industrial growth, and hot, dry conditions that increase air-conditioning and fan use. [3] [4] The 2030 outlook cannot be reduced to one uncontested number. GPL's July 2026 Development and Expansion Programme models a development-enabled potential peak of 1,575 MW for DBIS and 1,671 MW for all GPL systems plus Linden in 2030, with potential electricity demand of 10.44 TWh.

The same document labels the forecast as potential demand and ties the rise to data centres, major infrastructure, industrial activity, housing, Linden integration and wider economic growth. [1] An independent InterEnergy assessment, as publicly summarised by the President on 14 September 2026, states that electricity demand could rise by about 138 percent by 2029. The public disclosure does not state the exact demand metric, base period, system boundary, or large-load assumptions. Applying 138 percent to the 242.6 MW August 2026 DBIS peak produces about 577 MW, but that value is an author sensitivity only. It must not be represented as an InterEnergy point forecast. [5] A third lens appears in GPL's May 2026 Demand Side Management Action Plan. It targets 516 GWh of savings by 2030, described as a 20 percent reduction against projected electricity generation of 2,508 GWh.

Elsewhere, the same report states that total energy demand across GPL systems will grow by 2,508 GWh between 2025 and 2030, equal to 171 percent. The wording creates a scope ambiguity. The DSM document is useful for efficiency and load-shape analysis, but it should not be treated as a directly comparable 2030 peak forecast. [2] GUYANA POWER DEMAND 2030 | WHITE PAPER Ragunauth Ramsaroop | September 2026 | Page 3 White paper finding The strongest current public planning position is not “Guyana will use 1.67 GW in 2030.” The stronger statement is: GPL is building a system capable of serving a development-enabled demand envelope that reaches about 1.67 GW, while present operating evidence and the disclosed independent outlook point to a lower realised trajectory unless large step-load projects reach service on the assumed schedule. Key findings  The DBIS load trajectory has accelerated.

Peak demand rose from about 205 MW in 2024 to 221 MW in 2025, 242.6 MW in August 2026, and roughly 257 MW in early September 2026.  GPL's 2030 upper planning envelope is driven mainly by structural step-loads rather than ordinary customer growth. Total GPL + Linden customer accounts rise from 244,598 in 2025 to 305,764 in 2030, about 25 percent. Potential peak demand rises by more than 500 percent over the same period.  The first three data centres in GPL's forecast total 200 MW by 2028. That capacity equals about 78 percent of the recent 257 MW DBIS peak. The published annual MWh values do not reproduce from the data-centre formula stated in GPL's own appendix, so this paper uses the MW values for stress testing and flags the MWh values for clarification. [1]  GPL tracks 77 major infrastructure developments whose exact completion dates were undisclosed or unavailable.

The utility estimates 90.6 MW of additional demand by 2030 and 623.2 GWh of associated energy through a phased realisation method. Its methodology applies representative demand profiles, conservative uptime assumptions, and a demand factor of 1.0 for projects without confirmed dates. Those values are suitable as a screening envelope, not as 90.6 MW of firm contracted 2030 load. [1]  The first 300 MW Gas-to-Energy plant is under construction.

Current official implementation updates place the first 57 MW turbine at end-2026 and the full combined-cycle plant in the first half of 2027.  Guyana's emerging utility-scale supply architecture is increasingly organised around four prospective pillars: Wales Gas-to- Energy Phase I (300 MW), Wales Phase II (300 MW), Amaila Falls Hydropower (minimum 165 MW), and a future Berbice / Palmyra gas-to-energy development modelled at 300 MW in GPL planning. Their nominal capacities total at least 1,065 MW, but this paper does not treat that sum as guaranteed 2030 firm supply.

Phase I is in construction, Phase II remains in procurement and development, Amaila remains procurement-stage, and Berbice / Palmyra remains planning-stage and dependent on pipeline, plant, grid and demand milestones. [6] [7] [8] [9] [10] [21]  Under the full DBIS demand envelope, GPL's model labelled the "committed projects" scenario produces a 223 MW firmcapacity shortfall by 2030. That model label is not treated here as proof that every included supply project is financially or construction committed. GPL's final optimal pathway adds 450 MW beyond that scenario, with 108 MW in 2026 and 342 MW in 2029. [1]  Transmission and distribution constraints are already visible in parts of the system. GPL reported Region Four feeders at thermal limits in August 2026.

Its upper demand envelope is paired with major 230 kV and 69 kV reinforcement, substations, smart-grid systems, and distribution expansion. [1] [3]  Rooftop solar lowers daytime energy purchases. Guyana's peak occurs in the evening, so solar without storage does not remove the core 19:00 to 21:00 capacity challenge. Batteries, smart controls, efficient cooling and time-based demand management matter more for peak reduction.  A staged planning framework is safer than one-point forecasting. This paper uses 600 MW, 1,000 MW and 1,671 MW as 2030 stress tests. The first two are analytical sensitivities, not official forecasts. The third is GPL's published potential envelope.
