For contractors serving TNB, local councils and building owners, and for utility distribution teams: competent person visits, restoration targets, streetlight repairs and crew certificates on record.
Malaysian electrical contractors working for TNB, local councils and building owners, and utility distribution teams, use FieldEx as one system for field service management and maintenance management (CMMS). It plans competent person visits to substations, times fault repairs against TNB's service levels, runs street lighting repairs to council targets and tracks every crew's Suruhanjaya Tenaga certificate.
Contract work on Malaysia's distribution network runs on strict rules: Suruhanjaya Tenaga (ST) competency, registered contractors, monthly substation visits and restoration targets backed by customer rebates. FieldEx keeps the jobs, the people and the proof together. Book a demo with one of your contracts.
Suruhanjaya Tenaga's Performance Standard of Electricity Supply Services of TNB sets Guaranteed Service Levels (GSL). Under GSL2, supply after a low voltage fault must be restored within three hours. A medium voltage (33, 22 and 11 kV) breakdown must be restored within three hours in the listed cities, and four hours elsewhere. Where there is no alternative feed, the limit is 12 hours.
| Equipment (GO 165) | Patrol urban / rural | Detailed inspection |
|---|---|---|
| Overhead transformers, switches, conductors | 1 / 2 years | 5 years |
| Underground transformers and switches | 1 / 2 years | 3 years |
| Pad-mounted equipment | 1 / 2 years | 5 years |
| Street lighting | 1 / 2 years | Not set |
| Wood poles over 15 years, not yet tested | 1 / 2 years | Intrusive test within 10 years |

Natural disasters, bad weather and planned maintenance outages are excluded. If TNB misses a GSL2 target, affected consumers may claim a rebate within two months of the incident. TNB's GSL page sets the rebates: 1% of the monthly bill for domestic customers (at least RM10), 1% up to RM300 for commercial customers and 0.5% up to RM1,000 for industrial customers.
| GSL2 situation | Restore within |
|---|---|
| Low voltage fault | 3 hours |
| Medium voltage breakdown, listed cities | 3 hours |
| Medium voltage breakdown, other areas | 4 hours |
| Medium voltage breakdown, no alternative feed | 12 hours |

Regulation 67 of the Electricity Regulations 1994 links visits to voltage. An installation above 600 volts and up to 11,000 volts needs at least two inspection visits a month. One above 11,000 volts and up to 132,000 volts needs at least four. Above low voltage, the visits must be made by an Electrical Services Engineer or a Competent Electrical Engineer.
The engineer submits an inspection report to the owner within two weeks, under regulation 68. The same regulations require non-domestic installations to be checked and tested at least every five years, and protective relays to be checked, tested and calibrated at least every two years.
The CPUC adds that detailed inspection records must show each item's condition, any problems found and a scheduled date for corrective action.
| Installation voltage | Minimum visits a month |
|---|---|
| Up to 600 V, fed through 100 A or larger switchgear | 1 |
| Over 600 V up to 11 kV | 2 |
| Over 11 kV up to 132 kV | 4 |

The Electricity Regulations 1994 require every Electrical Services Engineer, Competent Electrical Engineer, Electrical Supervisor, Chargeman, Wireman and Cable Jointer to hold a valid Certificate of Competency for their category. ST's chargeman page lists the classes. A0 to A4 cover low voltage systems below 1,000 V, and B0 to B4 cover high voltage systems at 11 kV or 33 kV, with restrictions on aerial lines, power stations and generator synchronising.
Certificate holders must register with ST to work, and registration runs from one to five years. A Wireman with Three Phase Restriction (PW3) needs at least a year with a single-phase certificate and a year of wiring experience first.
| Situation (Ofgem) | Restore within |
|---|---|
| Normal weather, under 5,000 premises affected | 12 hours |
| Normal weather, 5,000 or more premises affected | 24 hours |
| Severe weather, category 1 | 24 hours |
| Severe weather, category 2 | 48 hours |

Regulation 75 of the Electricity Regulations 1994 says no one may carry out electrical work without a valid Certificate of Registration as an Electrical Contractor. Regulation 78 sets four classes by the value of work, each with a minimum number of full-time wiremen.
| Class | Work value | Full-time wiremen (from ST's ECOS page) |
|---|---|---|
| A | Above RM1 million | 1 PW4, 2 PW3, 2 PW1 |
| B | Up to RM1 million | 1 PW4, 1 PW3, 1 PW1 |
| C | Up to RM500,000 | 1 PW4 |
| D | Up to RM100,000 | 1 PW2 |

The registration is valid for one to five years. TNB adds its own step: an electrical contractor first registers with ST, then registers with TNB at the customer service centre for the area where it works.
TNB's vendor registration page says local suppliers and contractors must hold a valid TNB registration before taking part in its procurement. Suppliers of materials and services need Ministry of Finance (MOF) certification, and works contractors need Construction Industry Development Board (CIDB) certification. The processing fee is RM50 for each new registration, renewal or update.
TNB's tender notices add a further condition. Only vendors registered as Supplier Self-Service (SUS) suppliers can take part, and all certificates must be kept up to date in the portal.

Each council (PBT) sets its own target in its customer charter. Majlis Bandaraya Subang Jaya (MBSJ) says its area contractor repairs a faulty streetlight or park light in three days, with a maximum of 14 days. Vandalism, such as stolen components or a burnt feeder pillar, can take two months because parts must be ordered.
MBSJ also explains who owns which pole. Concrete poles belong to TNB, and galvanised steel poles are maintained by the council. Majlis Bandaraya Petaling Jaya (MBPJ) aims to process streetlight complaints within 24 hours of receiving them.
FieldEx builds the evidence as the work is done. Each job records when the crew arrived and left, watermarked photos of the fault and the repair, the parts replaced and whether the target was met, so the monthly report for TNB or the council comes straight from the jobs instead of paper forms and chat groups. Councils publish their own results: MBPJ's 2025 customer charter report counts how many streetlight complaints were processed within 24 hours, so a contractor's response times feed the council's public figures. For substations, regulation 68 of the Electricity Regulations 1994 also sets a two-week deadline for the competent person's visit report.
PG&E's 2025 GO 165 report shows why the detail matters. Three overhead detailed inspections were reported late after a check found an inspector had uploaded photos for the wrong asset. The reinspection was done the same day, but the record still counted as late.
Photos tied to the wrong asset make a completed inspection worthless. Capture them on the asset itself.
FieldEx keeps hundreds of substations, feeder pillars and streetlights on one register and one calendar. Each asset class runs its own cycle, the work is grouped by area, and the plan raises the jobs, so substation visits, feeder pillar checks and streetlight patrols share one calendar with each crew's day kept to one district. Regulation 67 of the Electricity Regulations 1994 sets how often the competent person visits by the installation's voltage, so each substation's cycle in the plan follows its own voltage class.
In FieldEx, utility crews and contractors work from the same job and the same asset record, and each party sees only what it needs. Contractor work such as line clearance, streetlight repairs, civil works or meter exchanges lands on the utility's asset history as soon as it's completed, without a separate system.
Many still rely on spreadsheets, paper job sheets and chat groups. FieldEx puts substations, feeder pillars, streetlights and meters on located records, plans competent person visits, times faults and repairs against targets and tracks crews' certificates. See our guide to CMMS software.
