TNB’s RM43 Billion Grid Upgrade Is Coming. Here’s What It Means for Your Electricity Bill
Table of Contents
Malaysia’s energy landscape is being rewired, and it will affect what you pay every month. At the Energy Transition Conference 2026 (ETCon26) on 4 June, Tenaga Nasional Bhd (TNB) announced it has delivered 4.3 gigawatts (GW) of installed renewable energy capacity, contributing more than a third of the country’s total renewable energy output, while a RM43 billion government-backed grid overhaul is underway.
What is Malaysia’s energy transition and why does it matter?
Malaysia’s energy transition is a long-term national plan to shift electricity generation away from fossil fuels toward cleaner, renewable sources. Under the National Energy Transition Roadmap (NETR), Malaysia is targeting 31% renewable energy (RE) by 2025, 40% by 2035, and 70% by 2050, with a goal of achieving net-zero emissions by 2050. The roadmap covers solar, hydro, bioenergy, and eventually hydrogen, and it shapes how much Malaysians pay for electricity, long-term.
TNB chairman Tan Sri Abdul Razak Abdul Majid confirmed that the government has committed RM43 billion under Regulatory Period 4 to modernise the national grid, describing it as “a key enabler for Malaysia’s clean energy transition”, covering infrastructure upgrades and expanding capacity to support the growing demand from data centres.
How does this affect my electricity bill?
Grid modernisation alone doesn’t guarantee lower bills, but the push toward renewables, particularly solar, is already helping reduce costs for households that participate. Solar PV installations at Parliament Malaysia and various government facilities have reduced electricity bills by up to 42%, with Parliament alone saving 22%.
For everyday Malaysians, the most direct entry point is rooftop solar. The Solar Accelerated Transition Action Programme (Solar ATAP), managed by SEDA Malaysia, opened online applications from 1 January 2026 via the eATAP system at atap.seda.gov.my. Under the scheme, residential and commercial users can install rooftop solar panels, self-consume the energy generated, and export excess electricity back to the TNB grid for bill credits.
Solar ATAP replaced the previous NEM 3.0 scheme as the main export programme, with a national ceiling of up to 500MW of rooftop installations. Capacity is limited and allocated on a first-come, first-served basis.
What new solar projects were announced at ETCon26?
Two significant projects were unveiled at the conference that signal where Malaysia’s clean energy pipeline is heading:
- A 785-megawatt peak (MWp) hybrid hydro-floating solar project, expected to be the largest of its kind in Southeast Asia
- A 750-MWp ground-mounted solar project
Both aim to support Malaysia’s aspiration of achieving 70% renewable energy capacity by 2050 or earlier. TNB’s GSPARX subsidiary has also hit 224MW of installed solar capacity across residential, commercial, and industrial rooftops, a reflection of growing uptake among Malaysians who have already made the switch.
Should I consider installing rooftop solar?
Rooftop solar is worth serious consideration if you own your home and have a consistently high electricity bill. Malaysia has an estimated 42GW of technical potential for rooftop solar, meaning the sun, at least, isn’t a limiting factor. Installation costs have fallen significantly over the past decade, and with Solar ATAP providing bill credits for exported energy, the payback period has shortened.
Before committing, it’s worth reviewing your current electricity usage and understanding how Solar ATAP bill credits work via the official SEDA Solar ATAP portal.
If you’re not ready for solar, smaller wins are available now. The SAVE 4.0 programme from SEDA offers up to RM400 in e-rebates for households that purchase energy-efficient air conditioners and refrigerators with 4 or 5-star energy labels from the Energy Commission.

What should Malaysians do now?
The energy transition is happening whether or not you actively participate, but those who engage early will benefit most. Whether it’s applying for Solar ATAP via seda.gov.my, claiming rebates under SAVE 4.0, or simply understanding how your TNB electricity tariff is calculated, taking stock of your household energy spending is a sound financial move.
GLCs and GLICs have committed a combined RM16.5 billion in renewable energy investments for 2026, capital is flowing into this sector at scale. For Malaysians with an interest in sustainable investing or unit trusts with green mandates, this macro shift is also worth tracking on the investment side.
