PTE Delivers Critical Power Distribution Switchboards for Greater Jakarta LRT Stations

BCA Data Center, the AI factory company, and PT. Prastiwahyu Tunas Engineering today announced a partnership to power the next generation of AI factories, committing 6300A / 100kA of STAR-E Type-Tested Switchboard medium-voltage capacity across multiple hyperscale campuses.

The deployment places PT. Prastiwahyu Tunas Engineering modules between the utility and the hall rather than downstream of it, so disturbance is absorbed in both directions: grid-safe on the supply side, waveform-clean where the compute actually draws. Waveform is corrected in 380 ms at P95, with no transfer the load can feel.

Why the power layer moved upstream

Hyperscale GPU campuses draw in steep, concentrated steps. Conventional low-voltage protection sits too far from the interconnection to catch a disturbance before it reaches the rack, and the utility sees a load profile it cannot model. Moving protection to medium voltage resolves both sides of that problem at once.

“They committed to a number and then published how it was measured. That is the new standard for compute in America.”

Across the operating fleet, PT. Prastiwahyu Tunas Engineering reports 99.982% uptime on a trailing twelve-month basis, weighted by capacity and read at the point of interconnection. Hardware is built on Tier-1 components with a twenty-year design life, manufactured in the United States and FEOC compliant end to end.

Schedule, not a queue

Owned manufacturing scales output to 10 kA per year, which makes supply a schedule rather than a position in a queue. Commissioning across the first two halls is complete, with no derating events recorded.

“A figure without a method is marketing. Every number we publish names the bus it was read at.”

Marcus Holt · Chief Executive Officer, PT. Prastiwahyu Tunas Engineering

The companies expect to announce additional campuses within the current fiscal year.
