BESS installation and commissioning records

Installation and commissioning records show how a stationary battery system was installed, tested, and handed over at a specific site, on a specific date, by named operators. The commissioning record must state the installer, the site, the system identifier, the installation checks, the electrical and functional tests passed, the protection settings applied, and any deviations from the design, with retests where a deviation was corrected. Handover must include the passport or linked record access, the safety information, the operating instructions, and the maintenance schedule, with the receiving operator named. A system that is energised without a commissioning record has no dated proof that it was tested in its installed configuration.

Installation means the physical placing, connection, and setting up of a stationary system at a site. Commissioning means the tests and checks that verify the installed system before handover. The scope is the site and system stated, for the commissioning date stated.

How is the stationary category decided?

BESS installation and commissioning records applies within that frame, and the record should not borrow an EV battery rule without checking whether the article applies to industrial batteries. Articles 12 and 77 is the operative provision for the point in question. A commissioning team handing over a storage system to a site operator should record the category decision, including the capacity calculation and the date, because the threshold decision decides whether a passport is required. A handover should list the system identifier, the test results, the protection settings, the safety information version, and the maintenance schedule, signed by the installer and the receiving operator on the handover date.

How is the record built in layers?

For BESS installation and commissioning records, each layer should name its source, its date, and its owner. The installation checklist, test reports, settings record, and handover note should be tied to the identifier, so a maintenance entry, a commissioning test, and a passport entry refer to the same system. A change to the system after commissioning, such as a module replacement or a software update that changes a protection setting, needs a new record entry, and the commissioning record should not be overwritten to hide the change.

How is performance measured in service?

For BESS installation and commissioning records, the record should state the capacity test method, the temperature range, the charge and discharge rates, the depth of discharge, and the end of life criterion used for a durability statement. A commissioning team handing over a storage system to a site operator should name the standard or method used for each value and should not present a laboratory value as a site value without stating the difference. A handover should list the system identifier, the test results, the protection settings, the safety information version, and the maintenance schedule, signed by the installer and the receiving operator on the handover date.

How is safety information recorded?

For BESS installation and commissioning records, the record should state the safety tests applied, the battery management system functions that protect the system, the ventilation or enclosure requirements, and the instructions given to the site operator. The installation checklist, test reports, settings record, and handover note should include the test reports, the installation instructions, and the handover of safety information, each dated. A change to the system after commissioning, such as a module replacement or a software update that changes a protection setting, needs a new record entry, and the commissioning record should not be overwritten to hide the change.

How are installation and maintenance recorded?

For BESS installation and commissioning records, the commissioning record should state the installer, the date, the tests passed, the settings applied, and any deviations from the design. A commissioning team handing over a storage system to a site operator should ensure that maintenance entries update the passport or the linked record where the Regulation requires an update, and that earlier entries are preserved. A handover should list the system identifier, the test results, the protection settings, the safety information version, and the maintenance schedule, signed by the installer and the receiving operator on the handover date.

How are transfer and end of life decisions recorded?

For BESS installation and commissioning records, a transfer of ownership, a change of application, a repurposing of EV modules into stationary service, or a move to recycling each needs a dated entry, a named operator, and a statement of what was transferred. The installation checklist, test reports, settings record, and handover note should include the state of health assessment, the safety checks applied, and the new application, where a second life use is claimed. A change to the system after commissioning, such as a module replacement or a software update that changes a protection setting, needs a new record entry, and the commissioning record should not be overwritten to hide the change. A commissioning team handing over a storage system to a site operator should check the passport or linked record at transfer, record any gap found, and give the gap an owner and a review date.

How is a commissioning failure closed?

Closing a commissioning failure starts with the failed test record: the test, the result, the expected result, and the date. The cause is investigated, the corrective work is recorded, and the test is repeated under the same method. A worked file for a failed insulation test shows the first result, the fault found in a cable termination, the rework, and the retest result, each dated, with the tester. The commissioning record is not signed until every test passes or a deviation is formally accepted with a reason, a risk assessment, and an owner. A deviation accepted without a reason and an owner is an open failure, not a closed commissioning, and the handover note should say so.

Commissioning is the first use phase entry, and a missing commissioning record leaves the whole operating history without a starting point.
