When the grid is the constraint: designing micro-grids for remote sites

Remote sites fail energy planning for a different reason than city sites. There is no fallback, so the architecture has to be complete.

A micro-grid is not a small power station. It is a complete energy system for a defined set of loads, designed around the site's duty cycle and operated unattended. The engineering problem is the same whether the site is a construction camp, a telecom tower or a barrage control facility: everything the loads need has to be inside the boundary.

Start with the worst week, not the average day

Remote sites are designed around their worst condition: the cloudiest stretch, the hottest week, the period of highest concurrent demand. A system sized for a sunny average will fail the first time the weather and the load peak coincide, and on a remote site that failure has a programme cost attached to it.

The four elements and the controller that binds them

• /Generation, sized against the worst-case irradiance window rather than an annual average.
• /Storage, sized for the longest expected gap between generation or grid availability.
• /Backup generation, kept for the residual case and used as little as the architecture allows.
• /A controller that decides which source serves which load, and that survives the loss of any single element.

Unattended operation is a design decision

If the site has no permanent electrical team, then maintenance access, component accessibility, fault isolation and remote monitoring are design requirements, not operational conveniences. A micro-grid that needs a technician on site to restart it after a trip is not complete.

Commissioning and operator competence

The final deliverable is not an installed system. It is a site team that understands what the system does in normal operation, what it does when supply is lost, and what they are not supposed to touch. Handover documentation and operator training are part of the commissioning scope, and a project without them is not finished.

RESOLV's documented micro-grid work includes a remote camp installation at the Guddu Barrage area, where the starting condition was no reliable utility supply.
