Sarawak’s solar regulatory environment is a distinct system from Peninsular Malaysia’s SEDA/TNB framework. Sarawak Energy Berhad operates the state’s electricity network under Sarawak’s own legislation — the Sarawak Electricity Ordinance 2012 — and has its own NEM scheme, its own application process, and its own contractor and engineering licensing requirements. Contractors and developers working across both Peninsular Malaysia and Sarawak must understand that approvals, licences, and procedures from one jurisdiction do not automatically apply in the other.
Peninsular Malaysia Licences Do Not Automatically Cover Sarawak
A contractor who holds an ST Electrical Contractor Licence for Peninsular Malaysia and a SEDA Solar PV Contractor registration is NOT automatically authorised to carry out solar installation or NEM applications in Sarawak. Sarawak’s electricity legislation is state law and SEB operates under different licensing requirements. Verify Sarawak-specific contractor and engineer authorisations before accepting projects in Sarawak.
Why Sarawak Has a Different Solar Regulatory Framework
Historical and Constitutional Context
Malaysia’s electricity sector is bifurcated along constitutional lines. Electricity supply in Peninsular Malaysia and the federal territories of Labuan and Putrajaya is governed by the federal Electricity Supply Act 1990 (Act 447). However, under Malaysia’s constitutional arrangement, Sarawak (and Sabah) have retained separate authority over their own electricity supply sectors.
Sarawak’s electricity is governed by the Sarawak Electricity Ordinance 2012, a state-level law. This means SEDA Malaysia, Suruhanjaya Tenaga (ST), and TNB have no jurisdiction over Sarawak’s electricity sector. SEB operates independently of TNB — Sarawak maintains its own grid, its own generation assets (primarily large hydropower), and its own distribution network.
The practical implication for solar installers: every approval, licence, and application required for a solar installation in Sarawak comes from Sarawak-based authorities, not from SEDA, ST, or TNB.
Sarawak’s Generation Mix and Solar Context
Sarawak’s electricity grid is dominated by large hydropower from the Bakun, Murum, and Batang Ai dams, which provide low-carbon baseload power. This is significant for solar because:
- Sarawak’s electricity tariffs are among the lowest in Malaysia — the abundance of cheap hydropower keeps rates low
- Lower tariffs mean lower savings per kWh from solar self-consumption, affecting financial returns
- SEB’s grid has ample generation capacity — the motivation for promoting distributed solar is different from Peninsular Malaysia’s more fossil-fuel-dependent grid
For commercial solar projects in Sarawak, the financial case depends less on energy cost reduction and more on energy cost certainty, corporate sustainability targets, and the specific consumption profile of the facility.
SEB’s NEM Scheme: Key Parameters
SEB’s NEM scheme for Sarawak follows a similar net billing concept to Peninsular Malaysia’s NEM 3.0, but the specific parameters — size caps, export credit rates, quota structure, and application process — are set by SEB and may differ from NEM 3.0.
Installers should confirm the following directly with SEB before project design:
| Parameter | Where to Confirm |
|---|---|
| Maximum system size (domestic and non-domestic) | SEB Commercial Services |
| Export credit rate (RM/kWh or ratio to import tariff) | SEB Commercial Services |
| Quota availability (if applicable) | SEB website / Commercial Services |
| Application documents required | SEB NEM application form |
| Processing timeline | SEB Commercial Services |
As of the last update of this guide, SEB’s NEM scheme was available for both domestic and commercial customers in Sarawak. Exact terms should be confirmed with SEB — scheme parameters have been updated in the past and the information on SEB’s website should be taken as the authoritative current reference.
SEB Electricity Tariffs in Sarawak
Sarawak’s electricity tariffs are set by SEB and are substantially lower than Peninsular Malaysia’s TNB tariffs, reflecting the low cost of hydropower generation.
| Customer Category | Indicative Rate |
|---|---|
| Domestic (Tariff A) | Significantly lower than TNB domestic rates |
| Commercial | Lower than comparable TNB Tariff B/C rates |
| Industrial | Among the lowest industrial electricity rates in Southeast Asia |
Financial modelling implication: Use SEB’s actual tariff schedule (available from SEB or from the customer’s SEB bill) for Sarawak solar financial models. Do not apply TNB Peninsular Malaysia tariff rates — they will overstate savings and produce incorrect payback periods.
Technical Requirements for Solar in Sarawak
The core technical requirements for solar installations in Sarawak are broadly similar to Peninsular Malaysia’s, reflecting the use of the same international IEC standards for inverters and panels. However, confirm the specific requirements with SEB, as SEB may have grid-specific protection settings or metering requirements that differ from TNB’s:
Inverter Requirements
Inverters must comply with MS IEC 62109 (safety) and include anti-islanding protection per IEC 62116. Anti-islanding must function within 2 seconds of detecting loss of SEB supply. Confirm with SEB whether the approved equipment list from ST (Peninsular Malaysia) is accepted, or whether SEB maintains its own list.
PE-Stamped SLD
SEB requires a PE-stamped Single-Line Diagram for all grid-connected solar applications. The PE must be registered with the Board of Engineers Sarawak (BES). Engineers registered only with the national Board of Engineers Malaysia (BEM) but without Sarawak-specific registration may not be authorised to stamp drawings for Sarawak projects — confirm this with BES before engaging an engineer.
Electrical Contractor Licensing in Sarawak
Solar installation and electrical work in Sarawak must be performed by contractors licensed under Sarawak’s electrical contractor framework. SEB’s requirements for contractor registration may differ from ST’s requirements for Peninsular Malaysia. Verify with SEB which licences are required before accepting installation work in Sarawak.

Common Issues for Contractors Working in Sarawak
| Issue | Cause | Resolution |
|---|---|---|
| Application rejected — contractor not licensed in Sarawak | Contractor holds only ST (Peninsular) licence | Obtain Sarawak electrical contractor licence via SEB’s licensing requirements |
| SLD rejected — PE not registered with BES | PE holds national BEM registration only | Engage a PE with BES registration; confirm BES registration number |
| Financial model overestimates savings | Using TNB tariff rates instead of SEB rates | Obtain current SEB tariff schedule; use actual customer bill for financial inputs |
| NEM quota unavailable | SEB NEM scheme is capacity-constrained or round closed | Confirm current SEB NEM quota availability with SEB Commercial Services |
| Anti-islanding settings not accepted | SEB uses different protection thresholds | Confirm SEB’s specific protection relay settings before programming the inverter |

Frequently Asked Questions
Can a Peninsular Malaysia solar contractor install systems in Sarawak? A contractor licensed only under Peninsular Malaysia’s ST Electrical Contractor framework is not automatically authorised to carry out electrical installation work in Sarawak. Sarawak has its own electrical licensing requirements under the Sarawak Electricity Ordinance. Contractors should contact SEB or the relevant Sarawak authority to understand what additional licences or registrations are needed before accepting Sarawak projects.
Is there an LSS equivalent in Sarawak for large solar farms? Sarawak has its own renewable energy programmes for larger-scale solar generation. SEB and the Sarawak government have run tenders for solar power under the Sarawak Green Energy plan — separate from Peninsular Malaysia’s LSS scheme run by the Energy Commission. Investors interested in large-scale solar in Sarawak should monitor SEB and Sarawak government announcements for current procurement rounds.
What is the solar market like in Sarawak’s rural areas? Rural Sarawak has a significant off-grid solar market driven by remote communities not connected to SEB’s grid. Off-grid solar systems in rural Sarawak are not subject to SEB’s NEM or grid connection requirements — however, government-funded rural electrification programmes have their own procurement and installation standards. Installers working in rural electrification programmes should confirm compliance requirements with the programme administrator.
Does Sabah have a similar separate solar regulatory framework? Yes. Sabah and the federal territory of Labuan are served by Sabah Electricity Sdn Bhd (SESB), which operates its own NEM scheme separate from both SEDA/TNB (Peninsular Malaysia) and SEB (Sarawak). Solar installers working in Sabah should contact SESB directly for current NEM scheme terms, application processes, and contractor licensing requirements.
