A retrofit is judged on the meter reading six months later, not on the commissioning photo. These are projects where we can show the before, the after, and the number in between — with the plant's own utility data as the reference, not ours.
We ask for three photos before quoting: the busbar, the label schedule, and the meter if there is one. That single step tells us whether the board takes our DIN breakers, whether a CT will fit, and whether the existing meter is worth reading or worth replacing.
The quote comes back as a line-by-line schedule: tag name, protocol, poll rate, panel, and alarm threshold. It is the document the electricians work from and the document the invoice is checked against.
A 61-panel site does not take 61 panels of stock in one drop. Releases are scheduled to the windows the plant can actually give, and the balance sits on our floor at no charge for 60 days.
Metering runs live for two to four weeks before anything is switched. It is the least glamorous part of the project and the only reason a savings figure survives an audit fourteen months later.
The plant signs off on a witnessed test: every tag polled, every alarm forced and cleared, every breaker tripped and reset. As-built drawings and the tag export go with it, in a format the plant owns.
Most installations are still there in year two and nobody opens the dashboard. The retainer exists to prevent exactly that: monthly review, alarm tuning, and a named engineer who knows the building.
