With Malaysia’s base electricity tariff rising by approximately 14% to 45.62 cent/kWh under Regulatory Period 4 – the first increase in over a decade – and a national carbon tax confirmed in Budget 2026 targeting heavy industry, the pressure on Malaysian manufacturers to control energy costs has never been greater. One Klang-based engineering firm decided not to wait.
EFS Group, a leading renewable energy and energy efficiency solutions provider, has completed a 403 kWp rooftop solar installation for Cheng Hua Engineering Works Sdn Bhd at its Klang facility – and the results are immediate. In its first full month of operation, the system delivered nearly a 50% reduction in electricity costs, while offsetting approximately 30% of the facility’s total electricity consumption. The system is projected to generate around 362,280 kWh of clean energy annually, reducing Cheng Hua Engineering’s carbon footprint by an estimated 400 metric tonnes each year.
“In today’s climate, energy resilience directly impacts profitability. Companies that act decisively are not only reducing emissions – they are strengthening their balance sheets,” said Mr Darren Tan, Chief Executive Officer of EFS Group.
The timing is deliberate. Malaysia’s new RP4 tariff structure, effective July 2025, has introduced significant increases for industrial low-voltage users, with low-voltage industrial energy charge rates now ranging from 48.08 to 52.17 cents/kWh, previously according to the Socio-Economic Research Centre. For energy-intensive operations like precision engineering, the monthly bill impact is material – and ongoing, as the new Automatic Fuel Adjustment (AFA) mechanism means tariffs now adjust monthly rather than every six months.
Beyond tariffs, the regulatory horizon is sharpening. Malaysia’s Budget 2026 confirmed the country’s first carbon tax – initially targeting the iron, steel, and energy sectors – with implementation set for 2026. While the specific tax rate has yet to be officially announced, the direction of policy travel is clear. Separately, Malaysian exporters face growing pressure from the EU’s Carbon Border Adjustment Mechanism (CBAM). For manufacturers with exposure to European supply chains, demonstrating a credible decarbonisation record is rapidly becoming a commercial prerequisite.
Cheng Hua Engineering is not a newcomer to solar. The company first adopted the technology in 2014 under Malaysia’s Feed-in Tariff (FiT) programme – making this latest expansion under the Self-Consumption (SelCo) a mark of a decade-long track record, not a leap of faith. Crucially, the installation was entirely self-funded, signalling management confidence in solar’s maturity as a bankable, long-term asset rather than merely an ESG checkbox.
“Solar has proven its reliability over the past decade, and this expansion allows us to take greater control of our energy consumption while aligning with Malaysia’s low-carbon ambitions,” said Mr Lim Chee Keong, Chief Executive Officer of Cheng Hua Engineering Works Sdn. Bhd.
The Klang project reinforces EFS Group’s position as a clean energy partner for Malaysian manufacturers navigating an increasingly complex energy and regulatory landscape. Malaysia’s National Energy Transition Roadmap (NETR) sets ambitious targets of 31% renewable energy capacity by 2025, 40% by 2035, and 70% by 2050 – and the window for early industrial adopters to gain competitive advantage is narrowing.
“Those who act now are not just reducing emissions. They are building the competitive infrastructure for the next decade of Malaysian manufacturing,” concluded Mr Darren Tan.
