Malaysia · Peak Shaving & Battery Storage
Now serving SEA-wide projects
Shave the peak.
Cut the bill.
Every Malaysian factory quietly pays for one bad half-hour a month, the 30-minute peak that sets your TNB Maximum Demand charge. We flatten it with battery storage. Whether you run the factory or you’re the EPCC building it, we handle the whole battery side: sizing, supply, financing and ten years of support.
Peak shaving, visualised
See the cut, before and after.
Demand spikes through the afternoon; the battery caps it at a target line and the meter never sees the peak. Here is the same load, with and without UniBess.

01 · Capability
We handle the whole battery side, so you don't have to.
You know civils, EPC and the grid inside out. Batteries are our job, not yours. Think of us as your battery department: we design it, source it, finance it and look after it for ten years, while you stay in front of the client.

System Architect
Sizing from 15-min load data, EMS dispatch, thermal, fire-safety, SLD & TNB ASP.
03
Project Financing
CAPEX (GITA-eligible) or Zero-CAPEX lease. Both pre-structured for the CFO.
04
Lifetime O&M
10-year O&M, live dashboard, monthly KPI reports. Co-branded to your project.
Use cases
More than peak shaving.
Peak shaving is the headline saving, but the same battery earns its keep in three more ways. We size for the one that pays, and let the rest stack on top.
Peak shaving
Cap the 30-minute spike that sets your TNB Maximum Demand charge, and cut the biggest line on the bill, every month.
How it worksEnergy arbitrage
Charge off-peak when power is cheap, discharge in the peak window, and pocket the Time-of-Use price difference.
How it worksBackup & resilience
Ride through dips and short outages on critical lines, working alongside your existing UPS and gensets.
How it worksSolar self-consumption
Store surplus rooftop solar instead of exporting it, and use your own clean power when demand is highest.

01
Battery expertise EPCCs lack
Our team has shipped, commissioned and supported BESS deployments across Southeast Asia. We've already made the mistakes, so your project doesn't.
02
Supply & logistics, covered
We buy proven LFP batteries straight from the factory and handle the whole chain: purchasing, shipping, customs, delivery. You get solid, fundable hardware and skip the procurement grind.
03
Financing that closes deals
Outright CAPEX (may qualify for GITA), Zero-CAPEX 7 to 10 year operating lease, or hire-purchase. We pre-structure both, so your client picks the financial profile that fits their CFO.
The problem we solve
One 30-minute peak sets the whole month's demand charge.
We flatten that peak with battery storage, and put the Maximum Demand saving in the contract, not just the pitch.

Bring us in as your battery team. You stay in front of the client with civils, EPC and the grid; we quietly take care of the sizing, the supply, the performance contract and ten years of O&M.
05 · Frequently asked
The questions people ask us first.
How does a BESS reduce my TNB Maximum Demand charge?
TNB Bukan Domestik ToU bills Maximum Demand on the highest 30-minute average kW during peak hours (08:00 to 22:00). At RM 97.06/kW combined (RM 30.19 capacity + RM 66.87 network), a single 30-minute spike sets the demand charge for the whole month. A correctly sized BESS discharges during those windows to cap demand at a lower target, capturing the MD saving every billing cycle.
Is an industrial BESS eligible for GITA in Malaysia?
Yes. Battery energy storage systems may qualify for the Green Investment Tax Allowance (GITA) under MIDA's green-technology framework, subject to MIDA approval and meeting equipment, performance and reporting criteria. UniBess prepares the GITA documentation as part of the financing package.
What is the typical payback for a Malaysian C&I BESS project?
For a Peninsular Malaysia C&I site with a Bukan Domestik ToU tariff and consistent peak demand, simple payback typically lands between 6 and 7 years on outright CAPEX. Zero-CAPEX operating lease converts the project to OPEX with day-1 positive cash flow, removing the payback question for the asset owner.
How does the EPCC partnership actually work?
UniBess plugs in as your battery layer. You stay in front of the client with civils, EPC and grid scope; we sit behind the bid with cabinet allocation, sizing, EMS design, financing options, and the 10-year performance contract. Proposals are white-labelled or co-branded; deal registration gives you per-project exclusivity and locked margins.
Why LFP chemistry and not NMC?
LFP (lithium iron phosphate) offers superior thermal stability, longer cycle life (typically 6,000+ cycles) and lower fire risk versus NMC. Critical for Malaysia's tropical climate, and for industrial sites co-located with personnel and stock. UniBess standardises on LFP for these reasons.
What battery hardware does UniBess use?
Proven LFP (lithium iron phosphate) BESS, built to recognised safety and quality standards (UL 9540A, IEC 62619 and TÜV) and backed by a written performance contract. The hardware credentials for your project (LFP chemistry, liquid-cooled, IP55 / IP54, C3 anti-corrosion, 10-year warranty, 70%+ capacity retention at Year 10) are confirmed upfront, with datasheets and test reports provided on request.
What's the typical lead time from PO to Phase 1 COD?
Approximately 22 weeks (about 5.5 months) for a Phase 1 pilot deployment. Full Phase 2 rollout COD lands at roughly 52 weeks (about 12 months) from PO. Schedule covers detailed engineering, TNB ASP/SLD approval, equipment manufacture, civil works, installation and commissioning.
If the savings aren’t real, we don’t want the project. Every number we promise goes into the contract. Not just the pitch.
