Clean Energy, Energy Storage
Storage, sized
to the site.
Uttam helps operators across Southeast Asia source the right storage solution for their site, on the right terms. From a single cabinet shaving a building’s peak to a utility block firming renewables.
01·What storage does
- 01
Peak shaving
Discharge through peak-tariff hours to cut demand charges.
- 02
Solar self-consumption
Store midday solar and use it on site after sunset.
- 03
Backup & diesel replacement
Carry critical loads through outages and cut generator run hours.
- 04
Grid & renewables firming
Smooth renewable output and support the grid at utility scale.
02·Product lines
Cabinet to container.
Two product lines, EAST and RelyEZ, cover commercial, industrial and utility-scale sites on lithium iron phosphate cells.
EAST · Commercial & industrial
C&I cabinets
Outdoor and indoor cabinet systems for a single building or a factory floor. All-in-one, hybrid PV and stacked formats, expandable as the load grows.

05·How we work
The site comes first.
01
Load profile & tariff review
We start with the site: interval load data, the tariff structure, the space available and the grid connection.
02
Sizing & payback model
Power and energy are sized to the duty cycle, and the payback is modelled against the site’s own tariff, with every assumption shown.
03
Sourcing & commercial terms
The site is matched to the right system from the EAST and RelyEZ lines, with clear terms agreed in writing.
04
Delivery & commissioning
Delivery, installation and commissioning are coordinated with local installation partners through to handover.
