Case Study 01
Indonesia Island Port Construction Microgrid
A mobile solar-plus-storage microgrid delivered by barge to an island port construction site with no grid connection, replacing round-the-clock diesel generation during the build programme.
- Client type
- Marine infrastructure contractor
- Sector
- Port construction
- Location
- Island site, Indonesia
- Delivery
- Barge-landed containerised system
Deployment background
The site sat on an island with no distribution network and no realistic path to a grid connection inside the construction programme. Every kilowatt-hour had to be generated on site.
Diesel was the default option, but fuel had to be shipped in by sea. Weather windows, barge scheduling and on-site storage all added cost and risk, and generator runtime had to be maintained even during low-load night periods.
The setting was environmentally sensitive coastline, so noise, fuel handling and spill risk were under scrutiny for the duration of the works.
Location: Indonesia | Application: Island Port Construction Site

The solution
Bright Grid deployed a BRIGHT EDGE Remote™ M200 mobile microgrid combining solar PV, battery storage and intelligent diesel coordination. The containerised system was delivered by barge and operational within days of arrival.
Outcome
Significant reduction in diesel generator runtime. Lower fuel consumption, reduced operating costs, and a scalable energy platform that adapted to changing construction demands throughout the project lifecycle. Demonstrates how mobile microgrids can accelerate infrastructure development in locations where grid access is unavailable or uneconomical.
- Rapid deployment to remote island location
- Significant diesel displacement from day one
- Containerised and relocatable for project lifecycle
- Scalable capacity as construction demands changed
