Your business’s trusted power bank. 
A Battery Energy Storage System (BESS) captures and stores electricity — from the grid or your solar — so you can use it when it’s most valuable. It’s your silent partner in lowering costs, boosting efficiency, and keeping operations running without interruption.
The new Capacity + Network charges (formerly Maximum Demand) are based on your highest demand spike each month. BESS performs “peak shaving” — automatically supplying stored power during those spikes so your charges stay lower for the entire billing period.
With Malaysia’s updated tariff structure, capacity and network charges are higher than ever. BESS stores energy when rates are low (or free from your solar panels) and discharges it during expensive peak hours. This directly cuts the most expensive portions of your bill without changing your operations.
Without storage, any excess solar you generate but don’t use instantly is wasted. With BESS, you can store that surplus energy and use it later — boosting your solar ROI and accelerating your payback time.
Charge BESS with solar and slash reliance on fossil fuels. This directly reduces emissions, strengthens ESG scores, strengthens investor confidence, and positions your business for sustainability-linked incentives.
In Malaysia, BESS is eligible for the Green Investment Tax Allowance (GITA) — allowing you to offset a significant portion of your investment cost. SunBESS qualifies for Malaysia’s Green Investment Tax Allowance (GITA), helping you recover a significant portion of your investment.
Electricity prices and carbon regulations are only moving upwards. Investing in BESS now locks in energy savings and positions your business to adapt seamlessly to stricter environmental policies in the future.
