Guyana
| Utility | Guyana Power and Light Inc. (GPL) |
| Regulator | Public Utilities Commission (PUC) |
| Residential | Residential Lifeline (Tariff A, under 75 kWh): fixed charge 341.54; energy rate 39.10. Residential (Tariff A, over 75 kWh): fixed charge 351.04; energy rate 43.43. The page does not label units; the energy rate appears to be per kWh and the fixed charge appears to be monthly. The 15% fuel rebate was folded into the energy rate, and no separate fuel surcharge applies. Dated (2021). Currency: not stated on page (presumably GYD). Effective: 11 April 2021.

| Commercial | Commercial (Tariff B): fixed/demand charge 2,467.00; energy rate 56.38 (as published, units not labelled). Dated (2021). Currency: not stated on page (presumably GYD). Effective: 11 April 2021. Source: gplinc.com |
| Rooftop solar | Net billing: Prosumers sign a Standard Offer Contract. Surplus exports go into an Energy Credits Bank that offsets future bills. Credit still unused after 12 months, less any amounts owed to GPL, is paid at 90% of the tariff then in effect. Standard coverage is for systems not exceeding 100 kW (the GPL page says under 100 kWac inverter rating). Larger systems need approval based on maximum demand and a Grid Code interconnection assessment. Implemented by the GEA and GPL. Started: 2025 (launch reported 30 June 2025).

| Grid code | GPL National Grid Code (Planning, Interconnection, Operational, Minimum Technical Requirements and Metering codes) (2017; Guyana Power and Light Inc.) Document Separate DG guideline: GPL Interim Interconnection Requirements v1.0. GPL also requires NEC 2014 Articles 690/705, IEEE 1547 and UL 1741, plus a Government Electrical Inspectorate certificate. |
| Note | Net billing launched in June 2025. The government has publicly promised no electricity price increase (news, Nov 2024). The GEA issued terms of reference for a GPL Distributed Energy Resources Study in Nov 2025. |
Suriname
| Utility | N.V. Energiebedrijven Suriname (EBS) |
| Regulator | Energie Autoriteit Suriname (EAS) |
| Residential | Household (huishoudelijk). Monthly basistarief: 1-phase SRD 211.78; 2-phase SRD 293.97; 3-phase SRD 349.13. Verbruikstarief: 0-400 kWh SRD 1.971/kWh; 401-900 kWh SRD 2.850; 901-1,500 kWh SRD 3.330; above 1,500 kWh SRD 4.680. No separate fuel charge. Under S.B. 2024 no. 41, tariffs are adjusted quarterly to the CBvS USD sell rate. These are the latest figures EBS publishes; it is not confirmed that they are still in force in Oct 2026. Currency: SRD. Effective: Consumption month December 2024. Source: nvebs.com, sris.sr |
| Commercial | Non-household. Monthly basistarief: 1-phase SRD 335.16; 2-phase SRD 670.32; 3-phase SRD 718.20. Energy: SRD 4.820/kWh for all consumption. Currency: SRD. Effective: Consumption month December 2024. Source: nvebs.com |
| Rooftop solar | Net metering (annual netting / ‘salderen’). Self-generators are connected with a bidirectional meter. Exports are netted against consumption on an annual basis. Applies to producers up to 63 A. No credit rate for surplus is published. Technical conditions, connection costs and settlement are to be set in the EAS Energy Sector Plan; in the meantime EBS applies its ‘Algemene- en Aansluitvoorwaarden voor Zelfopwekkers’.

| Grid code | None published (as at Oct 2026) DG connection conditions: EBS Algemene- en Aansluitvoorwaarden voor Zelfopwekkers. |
| Note | The March 2024 decree set USD-indexed quarterly adjustments and 7% residential increases in Jul, Sep and Nov 2024, in line with IMF commitments. No 2025-2026 tariff schedule was found. |
Trinidad and Tobago
| Utility | Trinidad and Tobago Electricity Commission (T&TEC) |
| Regulator | Regulated Industries Commission (RIC) |
| Residential | Rate A (Domestic), billed per two-month cycle: 1-400 kWh TT$0.26/kWh; 401-1,000 kWh TT$0.32/kWh; over 1,000 kWh TT$0.37/kWh. Customer charge TT$6.00 for two months. Minimum bill $10.00 + VAT per two months. No separate fuel charge listed. VAT applies. Dated: these are 2009 rates, still the ones T&TEC publishes. The RIC’s 2023 Final Determination set new residential tariffs (1-200 kWh TT$0.2800; 201-700 TT$0.4000; 701-1,400 TT$0.5400; >1,400 TT$0.6800 per kWh; customer charge TT$7.50), but as of the latest reports found (Feb 2025) Cabinet had not implemented them. Currency: TTD. Effective: 1 September 2009 (still current per the T&TEC tariff page). Source: ttec.co.tt, ric.org.tt |
| Commercial | Rate B (Commercial): TT$0.4150/kWh for all kWh. Customer charge TT$25.00 for two months. Minimum bill equals the two-monthly customer charge. VAT applies. Dated (2009). The RIC 2023 determination proposed B1 TT$0.5600/kWh and B2 TT$0.6700/kWh, each with a TT$35.00 customer charge (not implemented as of Feb 2025). Currency: TTD. Effective: 1 September 2009. Source: ttec.co.tt |
| Rooftop solar | None. No net metering or feed-in tariff found. An Aug 2026 Guardian article reports experts calling for feed-in tariffs and time-of-use net metering for rooftop solar; those are recommendations, so no scheme is in place. Source: guardian.co.tt |
| Grid code | None published (as at Oct 2026). Related standard: TTS 171-3:2011 Trinidad and Tobago Electrical Wiring Code – Part 3: Renewable Energy Systems and Interconnection Requirements (2011; Trinidad and Tobago Bureau of Standards) Document TTS 171-3 covers grid-interactive PV, fuel cells and small wind (up to 100 kW) operating in parallel with the grid. It is a paid standard. The RIC also publishes T&TEC Codes of Practice (revised 2020), which are service standards, not a grid code. No T&TEC transmission grid code document was found. |
| Note | The RIC’s 2023-2028 Final Determination (Nov 2023) proposed rate increases. The minister said in Feb 2025 that no increase could happen in 2025 and the matter was still before Cabinet’s Finance and General Purposes Committee (TTT). No 2026 implementation was found. |
