Every CMMS vendor will give you a polished 45-minute demo with clean dashboards, instant work orders, and a salesperson who answers every question with "yes, we do that." Six months after the contract is signed, plants discover the truth — the asset import broke on turbine fired-hour counters, the SCADA integration needs a $40K connector that was not in the proposal, the outage planning module was a roadmap item that has not shipped, and the NERC GADS report still needs an Excel export. Choosing the right power plant CMMS is not about which platform looks best in a 45-minute demo — it is about knowing what to test, what to ask, and what red flags actually predict implementation failure.

How to Evaluate Power Plant CMMS Software: The Demo Guide
A no-fluff framework for power plant maintenance leaders running CMMS evaluations — what to ask, what to test, what to score, and how to separate the platforms that will actually run your turbine fleet from the ones that just demo well.

The Five-Phase Evaluation Journey
Most plants evaluate CMMS the way they evaluate any other software — three demos, a feature spreadsheet, a price comparison, signed contract. That process selects the platform with the best sales team, not the best fit for power generation. The right journey treats every demo as a structured test against scenarios your plant actually runs.
01
Define your scenarios before the first demo
Document 3–5 real workflows from your plant — a turbine combustion inspection, a forced outage from boiler tube leak, a NERC CIP-007 patch evidence cycle, a major outage Gantt with 200+ tasks. These become the test cases every vendor must walk through live, on their platform, with your data.
02
Shortlist 3–4 vendors, not 8
Filter for power-generation-specific platforms first. A CMMS built for hotels or facilities will not handle fired-hour counters, EFOR tracking, or NERC GADS reporting — no matter how aggressively the salesperson nods. Use peer references and industry-specific reviews, not generic G2 rankings.
03
Run scenario-based demos, not feature tours
Send your test scenarios to each vendor in advance. Watch them execute live — turbine asset import, condition-based PM trigger from a vibration threshold, outage critical path with parts pre-staging, regulatory audit export. The platform either does the work or it does not.
04
Run a hands-on free trial with technicians
The maintenance manager loves the dashboards. The technician under the boiler at 3am decides whether the platform survives. Get the mobile app onto five technicians' phones for two weeks. Their feedback determines adoption. Their adoption determines ROI.
05
Score, validate references, then negotiate
Apply the scoring framework below to each finalist. Call two power plant references per vendor — not the case study the salesperson gave you. Confirm hidden costs (data migration, integrations, training, future user seats) before any contract conversation begins.
Twelve Things to Test in Every Demo
This is the field-tested checklist. Each item is a workflow your plant runs on a regular basis — and a workflow where generic CMMS platforms quietly fail. Make every vendor demonstrate every item live.
01
Asset Hierarchy Import
Bring a spreadsheet of 50 real assets — turbine, HRSG, BOP — with parent/child relationships. Watch the vendor import it live. If the demo skips this and uses pre-loaded data, that is a red flag.
02
Fired-Hour & Starts Counters
Power plants schedule turbine inspections by fired hours and starts, not calendar days. Confirm the platform handles both meter-based and calendar-based PM triggers — and that they can run simultaneously on the same asset.
03
SCADA / Historian Integration
Ask exactly which protocols are supported — OPC-UA, Modbus TCP, OSIsoft PI, DNP3. Then ask for a live demo of a sensor threshold triggering an automatic work order. "We have an API" is not the same as a working integration.
04
Mobile Work Orders Offline
Plant basements, intake structures, and switchgear rooms have weak signal. Open the mobile app, turn the test phone to airplane mode, complete a work order, sync when reconnected. If the data is lost, the platform fails for power plant field use.
05
NERC GADS / Compliance Export
Ask for a sample NERC CIP-007 evidence package or GADS event report exported from the demo environment. If the answer is "we generate the data, you build the report" — that is exactly the manual work you are trying to eliminate.
06
Outage Planning & Gantt
A planned major outage involves 500–2000 tasks, contractor coordination, parts pre-staging, and critical-path scheduling. Watch the platform load a real outage scope, level resources, and visualize critical path dependencies.
07
LOTO & Permit Workflows
Lockout/tagout enforcement is non-negotiable in power generation. The platform should require photo verification of isolation points before a work order unlocks for execution — not just a checkbox the technician can rush through.
08
Spare Parts & Inventory Linkage
Test the full chain: PM work order generated → required parts checked against inventory → shortage flagged → purchase requisition created → parts issued → cost charged to work order. Every break in this chain is a delay in real life.
09
KPI Dashboards (MTBF, MTTR, EFOR)
Plants need MTBF, MTTR, PM compliance, EFOR, and availability calculated automatically — not in Excel. Verify the platform pulls these from work order data with no manual recalculation, and that the formulas match your definitions.
10
Role-Based Access & Multi-Site
A fleet HQ user sees all plants. A site manager sees only their site. A contractor sees only their assigned work orders. Confirm role-based security works at the data row level — not just at the menu level.
11
Audit Trail & E-Signature
Every change to a work order, asset record, or PM schedule must be timestamped, attributed, and immutable. Critical PMs and compliance reviews require e-signature capture that survives audit scrutiny.
12
Implementation Timeline & Support
Get a written, week-by-week implementation plan with named resources and exit criteria for each phase. Confirm support SLAs in writing. "Dedicated success manager" should mean a name and email, not a marketing phrase.

The Demo Scoring Framework
A scoring framework converts subjective demo impressions into a comparable number across vendors. Weight every criterion by how often it surfaces in your daily operation — not by how impressive it looked in the demo.
| Evaluation Criterion | Weight | What "Excellent" Looks Like | Red Flag |
|---|---|---|---|
| Power Generation Fit | 20% | Native turbine/boiler/HRSG asset models, fired-hour counters, EFOR tracking, NERC GADS reporting built in | Generic asset categories, no power plant references, no native compliance modules |
| SCADA & Sensor Integration | 15% | Live demo of OPC-UA / OSIsoft PI / Modbus connection triggering automatic work order from sensor threshold | "We have an open API" with no working customer reference for SCADA integration |
| Mobile & Offline Capability | 15% | Full work order completion offline, photo capture, e-signature, automatic sync on reconnection | Mobile is a "view only" or browser-based tool with no offline buffer |
| Outage Planning & Gantt | 10% | Critical path visualization, resource leveling, contractor management, parts pre-staging in one workflow | Outage planning lives in Microsoft Project or Excel, not in the CMMS |
| Compliance & Audit Export | 10% | One-click export of NERC CIP, FAC, EOP evidence packages with timestamps and e-signatures | "You can export to CSV and build the report yourself" |
| KPI Dashboard & BI Integration | 10% | Pre-built MTBF, MTTR, EFOR, availability dashboards plus Power BI / Tableau connector | KPIs require manual Excel calculation; no BI integration |
| Implementation & Onboarding | 10% | Written timeline, named project resources, data migration included, technician training in package | "Implementation is custom-quoted" with no detail; training charged per hour |
| Total Cost of Ownership | 10% | Transparent per-user pricing, integration costs disclosed up front, no surprise modules required for core function | "Talk to sales for pricing"; required modules sold separately; mandatory annual support fees |
Six Red Flags That Predict Implementation Failure
Red Flag 1
Demo uses pre-loaded fictional data only
If the vendor will not import your asset list live, they are hiding integration friction. Real plants have messy data — the platform that handles yours in the demo handles yours in production.
Red Flag 2
Every feature question gets "yes, we do that"
No platform does everything well. A vendor who never says "that is on the roadmap" or "we partner with X for that" is selling, not consulting. Ask for the limitations list. Every honest vendor has one.
Red Flag 3
Pricing requires a "discovery call" first
Transparent SaaS pricing models exist. Vendors who hide pricing until they have a stakeholder list and a budget number are pricing the deal, not the product. You will pay more.
Red Flag 4
Customer references are all from outside power generation
A great hospitality CMMS does not become a great power plant CMMS by adding a "turbine" asset class. If the vendor cannot put you on a call with two real generation operators, the platform was not built for your environment.
Red Flag 5
SCADA integration is "available via partner"
A partner integration adds a third party to the contract, the support escalation chain, and the upgrade cycle. Native integration is faster, cheaper to maintain, and survives vendor partnership changes.
Red Flag 6
Training and support are quoted separately
Vendors who charge for every support call or limit training to set hours are setting up the relationship to extract more revenue post-contract. Unlimited training and support should be standard, not premium.
Questions to Ask Real Customers, Not the Salesperson
"How long did implementation actually take versus the original estimate?"
Salespeople quote 8 weeks. Customers report 16. The gap is your project risk.
"What did the SCADA integration cost — including the consulting hours?"
Software cost is half the integration story. Get the labour number too.
"How does support actually respond when something breaks at 2am?"
Support quality is invisible until it is critical. Reference customers will tell you the truth.
"What features did you find missing after go-live?"
Every implementation discovers gaps. The pattern of those gaps tells you what the demo skipped.
"What percentage of your technicians actually use the mobile app daily?"
If adoption is below 70%, the platform fails the field test regardless of what the dashboard shows.
"What would you do differently if you ran the evaluation again?"
Most honest answer in any reference call. Listen carefully.
Frequently Asked Questions
How many CMMS vendors should I evaluate before deciding?
Three to four is the sweet spot. Fewer than three means thin comparison. More than five creates decision fatigue and stretches the evaluation past the point where stakeholders stay engaged. Book a demo to add OxMaint to your shortlist.
How long should a free trial be to properly evaluate a CMMS?
Two weeks minimum with at least 5 technicians using the mobile app daily. Anything shorter only tests configuration; you need real work-order volume to test usability under pressure. Start a free trial with no time pressure.
What is the most important demo question for power plant buyers specifically?
"Show me a sensor threshold triggering an automatic work order, end to end, on real SCADA data — right now." If they cannot, the predictive maintenance and condition-based PM story is marketing, not capability.
Should I bring my IT team into the CMMS evaluation, or is this a maintenance decision?
Both. Maintenance owns the requirements; IT owns the integration, security, and NERC CIP cyber compliance review. Single-team evaluations almost always discover the missing requirement after the contract is signed.
What hidden costs should I ask about before signing a CMMS contract?
Data migration, SCADA/historian integration, training hours, additional user seats, premium support tiers, custom report development, mandatory annual maintenance fees, and renewal escalation clauses. All of these belong in the TCO calculation.
Is a generic CMMS ever acceptable for a power plant if the price is right?
Only if the plant has no NERC CIP exposure, no SCADA integration plans, and no fired-hour-based PM cycles — which describes almost no real power plant. The generic CMMS savings disappear within a year against compliance, integration, and adoption costs.
