RM1M+ Lifetime Savings

Under the TNB Medium Voltage General tariff, the MD charge is RM89.27/kW per month based on your highest 30-minute demand reading. For a steel or chemical plant with 1,000 kW peak demand, that is RM89,270/month — over RM1.07M per year — just in MD charges, before even counting energy consumption. Solar alone does not reliably cut MD (one cloudy 30-minute window can set the month's maximum demand); a BESS controller can help, sized from your own demand data.

Under GITA, qualifying solar capex receives a 60% allowance (Tier 2) and BESS capex a 100% allowance (Tier 1), set off against up to 70% of statutory income. For a RM2.4M (1 MWp) solar system, that is a RM1.44M allowance — worth up to RM345,600 in corporate tax (at 24% rate) if fully absorbed. The system must be commissioned and the GITA application submitted to MGTC by 31 December 2026.

Under the Solar ATAP framework, non-domestic systems are capped at 100% of the site's maximum demand (MD) in kWac, with a ceiling of 1,000 kWac. Solar output is used on site first. Any export credit is forfeited at the end of each billing period (no carry-over), so we size the system to your daytime load rather than to export.

Where a BESS is recommended, its controller monitors your load profile in real time and discharges the battery to smooth machinery startup spikes, helping keep your measured demand below the MD threshold. The controller and battery are sized on your own demand data. This is the difference between paying RM89.27/kW on the full spike or only on your capped demand on your next TNB bill.
