Grid Code
The Grid Code is a regulatory instrument used to coordinate various electricity supply activities of the electricity producer, operator, distributor and the consumer.
The Grid Code for Peninsular Malaysia was first issued by the Energy Commission based on the approval made by the Commission on 8 June 2010 and by the Minister on 21 December 2010. Pursuant to Section 42 of the Electricity Supply (Amendment) Act 2015 [Act A1501], the Code shall continue in full force and effect from the date of registration.
About Us
The Grid System Operator (GSO) is primarily responsible for the day-to-day real-time operation and the management of the Peninsular grid system, together with the short and medium term planning of the transmission network and generation facilities. This includes the interconnections with Thailand and Singapore. Our main focus is to operate the grid system in a “Safe, Reliable and Economical” manner.

Existing Constraints
Existing Constraint is described by its type of constraints such as inter-area power transfer limitation; circuits in the Grid being constrained; transmission assets’ voltage and thermal limits impacted by the constraint; quantum of generation limit to be limited from which generation clusters; and some additional operational remarks if any.
| Type | Constrained Cct | Voltage | Max Overload (%) | Generation Limit | Generation Cluster | Other |
|---|---|---|---|---|---|---|
| Contingency | 275kV ATWR-BGJH-TPAH-BTRK (2x683 MVA) | 275 | 150 | Limit based on max secured Perak-Central Area transfer | Northern | Limit to the max secured Perak-Central Area transfer to cater for thermal overload and system stability under n-2 contingency of 500kV BTRK-JMJG & BTRK-ATWR |
| Basecase | 275kV and 132kV cables into Penang Island | 132 | 100 | GLGR Min = 70 | GLGR | Min 1 GLGR GT on-bus required for thermal loading control and voltage support in Penang Island during weekdays |
| Contingency | 275kV SRDE-SLKS/PULU, CBPS-BRGS, BAHS-KAWA, YGPN-SMTI and BBTU-YGPN/BPHE lines | 275 | 130 | South Max 4000MW | South | Constraint–OFF to limit Southern generation |
| Contingency | 275kV CBPS-BGRS | 275 | 130 | Minimum 1 Unit at PKLG | Central | To run minimum 1 Unit at PKLG to cater for n-1 275kV CBPS-BRGS line contingency |
Constraints Due to Outage (for the next 7 days)
Constraints Due to Outage is described in similar manner however additional information is included which is the outage duration period of the transmission assets giving rise to the system constraints.
| Start | End | Type | Constrained Cct | Voltage | Max Overload (%) | Generation Limit | Generation Cluster | Other |

FAQ
As a ring-fenced entity, GSO is required by the industry to demonstrate transparency, independence and non-discriminatory conduct in its operations. One of the platforms to achieve this is with the establishment of the GSO Website in order to publish relevant operation information publicly.
The Website is public. The industry players are given special privilege to apply for an account with this platform in order to access operation data specific to their business portfolio, provided that they conform to the account application process.
We publish data for the Peninsular Malaysia grid system consisting of power station information, system generation and demand profiles, fuel mix and tie-line data, and system constraints. The website also publish relevant documents that are required under the GSO Ring-Fencing Rules and Regulations.
All operations data are updated in a timely manner. Any additional publication will be updated accordingly.
