Virtual wheeling: one solar plant, many sites

Many South African businesses want solar to cut cost and steady their supply, but their sites are the wrong places to put it: stores in malls with no roof rights, factories on shaded or crowded plots, operations spread across several municipalities.

Virtual wheeling lets a business generate power in one place and use it somewhere else.

How it works

A solar plant is built where the sun and the land are cheapest, and feeds its power into the grid. Eskom or the municipality meters what goes in and credits the business’s accounts at its offices or factories elsewhere. No electrons travel from A to B; it is a reconciliation, and the utility bill becomes the ledger.

What it takes

The idea is simple; the execution is not. It needs three things done properly.

• Site selection and generation. A location with high yield keeps the cost of each unit low, which sets the value of every credit.
• Grid and regulatory integration. Agreements with Eskom or the municipality that make the wheeling path between plant and offtaker legally and technically sound.
• Metering and reconciliation. Smart meters that report time-of-use data to the utility, so every kWh generated is credited at the right rate.

Where it pays

For a business with many branches or depots, wheeling turns a scattered energy problem into one plant and one contract. It hedges against tariff increases across the whole footprint without putting a panel on a single branch roof.

Regulation is still opening up, and every wheeling project starts with a feasibility check on the specific accounts and municipalities involved.

Imvelo assesses wheeling feasibility case by case. It is not part of the lease-to-own offer.
