Stationary storage & BESS
Follow identity, performance, safety and life stage evidence for stationary battery systems and grid storage.
Record the system, not just the cells
A stationary system record connects the system identifier to installation, commissioning, performance, safety and maintenance evidence, with module level detail where the system is assembled from modules.
Useful starting points
- State the system category and capacity basis.
- File installation and commissioning evidence with dates.
- Keep maintenance and safety entries in sequence.

What Diagnostics Fields Belong in a BESS Passport Record?
Diagnostics fields for a BESS passport record state fault codes, alarm history, sensor readings, and diagnostic evidence with dates, methods, and sources, so a later reader can trace what was recorded without re-performing any test.
BESS and grid services evidence
BESS grid services evidence is the operational record of frequency, capacity, and energy services actually delivered, with the service, the period, and the measurement method stated, separate from the passport.
BESS installation and commissioning records
Installation and commissioning records show the installer, the site, the tests passed, the settings applied, and the handover, with deviations and retests recorded and dated.
BESS maintenance records
BESS maintenance records show each inspection, test, repair, and software change, with dates, measurements, parts, and the next scheduled check, linked to the system identifier.
BESS operator duties
BESS operator duties cover the placing operator, the installer, the site operator, and the owner, with responsibility for the passport, safety information, and maintenance clearly assigned.
BESS passport timeline
The BESS passport timeline runs from the industrial carbon footprint declaration in 2026 through the passport duty on 18 February 2027 to later duties, each with its legal basis and status.
What Does a BESS Performance Scorecard Record Contain?
A BESS performance scorecard is a dated record artefact that gathers the identity, basis, source, tier, and review entries for performance evidence about a stationary battery system, without restating the underlying measurements as a fresh test result.
BESS performance data
BESS performance data states capacity, power, efficiency, and durability under stated site and test conditions, with factory and site acceptance results kept separate.
What SAT and Zero-Export Test Records Does a BESS Commissioning File Need?
SAT and zero-export test records for a BESS commissioning file are the dated, identified, pass or fail evidence that the installed system met its site acceptance criteria and that grid export stayed within the agreed limit.
BESS safety and fire information
BESS safety and fire information covers thermal runaway, venting, enclosure, detection, suppression, and emergency response for the installed configuration, with test basis and dates stated.
BESS scope and categories
BESS scope covers stationary storage systems that are industrial batteries, with the category, capacity, chemistry, and application recorded before any passport or safety decision.
What Screening and Testing Evidence Belongs in a BESS Record?
Screening and testing evidence for a BESS record links each screening result and test result to an identified battery, a named method, a dated report, and a named tester, so a later reader can trace the claim without repeating the test.
BESS second life
BESS second life covers repurposed EV modules and reused stationary modules in a new stationary application, with assessment, safety checks, and a new or linked passport.
BESS used market
The BESS used market depends on a transfer record showing system identity, module history, state of health, safety information, and maintenance, so a new site can judge suitability.
Industrial over 2kWh threshold explained
The industrial over 2kWh threshold is the capacity test in Article 77 that decides whether an industrial battery needs a passport from 18 February 2027, with the capacity basis recorded.
Stationary record anatomy
The stationary record anatomy separates identity, composition, performance, safety, and life stage layers, with system level and module level information linked by identifier.
