CNY Shutdown Readiness Checklist for Critical Facilities

In 2026, the Chinese New Year (CNY) falls on 17–18 February (Tue–Wed). CNY is one of the most predictable reduced-manpower windows for critical facilities in Singapore. When teams are lean, downtime rarely comes from a single component failing — it comes from gaps: unclear ownership, alarms that are ignored, transfer sequences that were never proven end-to-end, and interfaces (ATS, controls, monitoring) that don’t behave the way everyone assumes.

This checklist is a last-mile operational readiness review focused on the systems that carry the most weight during an incident —UPS/DRUPS and generator sets — plus the handover points where avoidable downtime often begins: ATS/switchgear, controls, monitoring, and procedures.

In 2 minutes: Follow the 9 steps below to validate your transfer path, confirm alarms reach the right people after-hours, and enter CNY with a defined change-freeze and a proven functional verification plan.

At-a-glance Checklist

Use this as your pre-CNY “last-mile” review:

• • Confirm Holiday PIC + backup, escalation contacts, site access rules, and vendor response coverage
  • Verify single line diagram matches as-built, labels are correct, and critical loads are clearly identified
  • Review DRUPS/UPS alarms + event logs; no critical alarms should be “normalised” without action
  • Confirm DRUPS/UPS operating state (including bypass status, interlocks, and runtime assumptions)
  • Verify gensets are in AUTO and ready to start, stabilise, and accept load
  • Validate fuel system readiness (quantity and transfer/day tank/alarm behaviour + refill logistics)
  • Check ATS/switchgear modes, interlocks, and settings governance (no undocumented changes)
  • Ensure monitoring & alarm routing reaches the right people after-hours; test remote access
  • Confirm safety and fire protection systems are normal; manage any impairments formally
  • Run a controlled functional verification (where feasible) and close gaps before the change-freeze window

If you only have time for one thing: validate the sequence

utility fail → ride-through → genset start → transfer → stable delivery → alarms confirm success.

Scope and assumptions

• • This is an operational readiness checklist for critical facilities preparing for holiday conditions.
  • It is not a replacement for OEM procedures, statutory requirements, or your site’s method statements.
  • Any testing should be conducted by qualified personnel with approved risk controls and permit-to-work processes.

Phase 1: The Paperwork & Plan

1) Governance and Escalation

Holiday readiness fails fast when ownership is unclear.

Minimum actions

• Assign a Holiday PIC (primary + backup) with direct phone numbers
• Share an escalation matrix (who decides what, and in what time window)
• Confirm site access: security procedure, escort rules, entry approvals, keys/cards, after-hours access
• Confirm vendor/service coverage: response time, contact method, and any standby arrangements
• Define a change-freeze window (and an exception approval process)

Delivery Assurance outcome: when something happens, you don’t lose 60 minutes to “who is responsible?”

2) Single-line “reality check”

During a crisis, your relief staff will trust the Single Line Diagram (SLD) implicitly. If the map is wrong, their response will be wrong. A "paper vs. reality" gap is a common failure point when the usual site experts are on leave.

The "As-Built" Walkdown

• Don't trust the PDF: Physically walk the electrical room with a printed SLD. Did that recent upgrade project actually get updated on the master drawing?
• Trace the changes: Verify that any temporary bypasses or "red-lined" changes from the last maintenance window have been normalized or clearly documented.

The "Label" Audit

• Match the floor to the page: Does Breaker Q4 actually feed the Critical IT Load, or was it swapped last month? Verify that physical labels on breakers, ATS, and bus sections match the diagram exactly. Ambiguity causes hesitation (or errors) during manual transfers.

Load Profile Reality

• Check the "Now": "Old assumptions" are dangerous. Has IT added new high-density racks since the last shutdown? Verify your current load level to ensure your N+1 assumptions (and fuel calculations) are still valid for the holiday window.

Holiday Hack: Print a fresh, large-format SLD for the control room wall. Use a red marker to physically highlight the primary emergency transfer path so a tired operator doesn't have to guess at 3:00 AM.

Phase 2: The Hardware Health Check

3) DRUPS / UPS readiness (availability + alarms + operating state)

Holiday incidents often trace back to “we’ve been seeing that alarm for weeks.”

Delivery Assurance outcome: the ride-through system behaves predictably, and alarms are trustworthy—not background noise.

4) Genset Readiness (start, stabilise, sustain)

A genset that “starts” but doesn’t stabilise or take load is still a failure scenario.

Starting Reliability

• Verify starting batteries, chargers, and terminals are healthy and secure
• Confirm the unit is in AUTO (and not left in MANUAL after earlier tests)

Control Sequence Clarity

Make sure the team can clearly answer:

• What happens from utility fail → start → warm-up → breaker close → load acceptance?
• Which conditions must be met before closing / transferring?

Load Acceptance and Stability

• Confirm expected load steps and stability expectations
• Review protection/trip history and unresolved warnings
• Ensure your team understands “what good looks like” in the first minutes after transfer

Delivery Assurance outcome: the genset can reliably deliver stable power—not just crank.

5) Fuel system readiness (a hidden risk)

Fuel risk isn’t only about quantity. It’s a system: sensors, pumps, valves, transfer logic, day tanks, alarms, and refuelling logistics.

Delivery Assurance outcome: fuel levels are verified, transfer/valve/pump logic is proven, and refuelling can happen within the holiday response window — not just “in theory.”

6) ATS / Switchgear / Protection Coordination (where transfers fail)

This is where “it should transfer” turns into “it didn’t.”

Operating Modes and Interlocks

• Verify ATS/switchgear modes are correct
• Confirm interlocks (mechanical/electrical) and operating conditions are understood

Settings Governance

• Ensure any changes are documented, approved, and traceable
• Avoid “mystery settings”—especially before holiday periods

Condition Review

• Review recent inspection records and any known hotspots or issues that are pending closure (where available)

Delivery Assurance outcome: transfer is controlled and selective—one fault shouldn’t become a whole-site event.

Phase 3: The Safety Net

7) Monitoring, alarms, and remote visibility

During the CNY shutdown, your facility might be a ghost town. Even the best backup systems fail if the right person doesn't get the right alert at the right time. Since you won't have eyes on-site, your remote monitoring system becomes your only line of defense.

The "5-Alarm Test" (Functional Verification)

Don't hope your sensors work—prove it. Simulate these 5 critical faults to ensure the signal travels from the genset → to the BMS → to your phone:

1.  Fail to Start (Overcrank)
2.  High Water Temperature
3.  Low Oil Pressure
4.  Low Coolant Level
5.  Emergency Stop Activation

Delivery Assurance outcome: You catch problems while they are small warnings, not after they become catastrophic failures—guaranteeing your holiday remains a holiday.

8) Safety & Fire Protection Readiness

Operational readiness is useless if the building isn't safe. During the holidays, the "human sensors" (staff walking by and smelling smoke) are gone. Therefore, the automated safety systems must be 100% reliable because they are flying solo.

The "Red Tag" Review

• Clear the impairments: Do you have any smoke detectors covered, or zones disabled due to recent maintenance? Review every single "impairment permit" now. Do not leave a zone disabled over the long weekend just because "we'll fix it next week."
• The "Contractor Dash" Cleanup: Contractors often rush to finish jobs before the holiday break. This leads to leftover debris, blocked exits, or cardboard boxes left near electrical panels. Walk the site after the contractors leave.

Housekeeping as a Defense

• Combustible patrol: Remove trash, oily rags, or packing materials from plant rooms. A clean room is a fire-resistant room.
• Access assurance: Ensure key cards for emergency exits and fire command centres work. Don't let a relief security guard get stuck outside the fire control room during an alarm.

Delivery Assurance outcome: You ensure that even without a full crew, the facility retains its ability to detect and suppress threats automatically.

9) The Last-Mile Functional Verification

This is the difference between "Confidence" and "Hope." Paperwork and green lights on a screen are nice, but they are theoretical. Before the shutdown begins, you need physical proof.

The "Blackout" Simulation

• Don't just inspect—act: Where safe and approved, perform a live functional test. Don't just look at the ATS; force a transfer. Don't just look at the battery voltage; put it under momentary load.
• Validate the logic: Did the cooling pumps restart after the power transfer? Did the security gates stay closed? It’s the auxiliary systems that usually cause the headaches.

The "Change Freeze" Gatekeeper

• The "Pen Down" moment: Treat this verification as the hard line. Once this test is passed, declare a strict Change Freeze. No more "quick tweaks," no more software updates, no more "just checking one thing."
• Pass/Fail Clarity: If a system acts weirdly during this test, it does not enter "Holiday Mode." It gets escalated immediately. Better to fix it Tuesday night than Friday morning.

Delivery Assurance outcome: You replace "I think it works" with "I just saw it work," allowing you to walk away for the holiday with zero doubt.

The "Silent Killers": Common Pre-Holiday Failure Patterns

We’ve analyzed years of incident reviews, and these are the patterns that repeatedly cause holiday downtime:

The "Manual" Mistake

A genset left in MANUAL or OFF mode after a routine test, ensuring it stays silent when the power cuts.

The Ghost Contact

Critical alarm notifications routed to an employee who left the company months ago (or is currently on a flight).

The Day Tank Trap

Transfer pumps that pass a 5-minute test but fail (or overheat) under the continuous load of a 4-hour outage.

The Post-Maintenance Glitch

ATS or switchgear left in a "Local" or "Service" mode after last-minute cleanup work, preventing automatic operation.

The "Not My Job" Gap

Critical interfaces (controls, BMS points, trip logic) that everyone assumed someone else was checking.

The Silent Battery Drain

Battery chargers that were accidentally tripped or unplugged during recent work, leaving starter batteries to slowly die just before the holiday.

If you recognize any of these risks, fixing them is your highest ROI activity before CNY.
