Built is not operating

Picture a solar plant where every panel is mounted, every row is wired, and the construction crews have gone home. From the road it looks finished. On paper it has not yet sold a single kilowatt-hour.

The gap between a plant that is built and a plant that is operating is commissioning. Protection settings are tested, the control system is proven to the grid operator, the utility witnesses the tests it requires, and the paperwork for commercial operation is signed. Until then the project earns nothing.

The last stretch of the work decides the day the revenue starts.

EIA’s August 2026 inventory lists 96 solar plants, 11.8 gigawatts, as construction complete but not yet in commercial operation. Behind each one is an owner watching a date.

What outsiders miss is that this stage needs different people from the ones who built the plant. Commissioning agents, protection engineers, testing firms and controls integrators are specialists, and they cannot be hired the week they are needed.

That is why the introduction belongs at the start of construction. A developer who meets the right commissioning team while the site is still being graded has one less reason to miss the date in the contract.
