Power plant operators spend 15–25% of operating expenditure on maintenance, yet nearly 70% of unplanned downtime still traces back to poor vendor accountability and contracts written around effort instead of outcomes. Performance-based maintenance (PBM) contracts flip that model on its head — paying contractors for measurable results like availability, heat rate, response time, and forced outage rate rather than hours on site. The catch: a performance-based contract without live KPI tracking is just an expensive promise. A modern CMMS platform built for contractor KPI tracking and SLA enforcement is what turns those guarantees into money the plant actually collects when contractors fall short.

Performance-Based Maintenance Contracts: The Software That Makes Them Enforceable
Availability guarantees, response-time SLAs, heat-rate commitments, liquidated damages — every clause in your O&M contract means nothing without the data to prove compliance. OxMaint delivers real-time KPI scoring, automated SLA alerts, and contractor performance dashboards that turn your contract terms into enforceable operational reality.

The Fundamental Shift
From Paying for Effort to Paying for Outcomes
Traditional time-and-materials O&M contracts pay a contractor for showing up. Performance-based contracts pay them for results. The difference is worth millions in uptime — if you have the data infrastructure to prove who delivered what.
Old Model
Time & Materials
Vendor gets paid for hours worked and parts consumed. Their incentive: more labor, more parts, more billable events. Reliability is the plant's problem.
Fixed labor rates regardless of outcome
Parts mark-ups reward replacement
Uptime risk sits entirely with owner
No contractual consequence for failure
shifts to
New Model
Performance-Based
Vendor is paid against measurable outcomes — availability, MTTR, heat rate, forced outage rate. Bonus for exceeding targets, liquidated damages when SLAs breach.
Fee tied to availability guarantee
Response-time SLAs with penalties
Shared risk and shared upside
Every KPI audited and enforced
The Enforcement Layer
Five KPIs Every PBM Contract Needs OxMaint to Track
A performance-based contract is only as strong as its measurement. These are the five KPIs that separate enforceable agreements from aspirational ones — and every one of them must be calculated from the same work-order and sensor data the contractor is held to.

Penalty <97%
Target 97–99.5%
Bonus >99.5%
Response Time
Bonus <2hr
Target 2–4hr
Penalty >4hr
MTTR (Repair)

Make Your SLAs Enforceable
Every contractor KPI calculated live from the same system that generates your work orders.
OxMaint turns every clause of your performance-based contract into a live dashboard metric — visible to your ops team, your contractor, and your auditors simultaneously. No more monthly reconciliation arguments.
Platform Capabilities
What OxMaint Brings to Every PBM Contract
A performance-based O&M contract needs five things from its supporting software: immutable data, contractor-visible dashboards, automated alerts, clean audit trails, and the ability to settle invoices without a fight. OxMaint delivers all five in one platform.
01
Immutable Work Order Log
Every service request, dispatch, arrival, and completion timestamp is captured automatically and cannot be edited retroactively — the single source of truth for every SLA calculation.
02
Role-Based Contractor Portal
Your O&M partner logs into the same platform but sees only their assigned assets, work orders, and performance scores — no spreadsheet reconciliation between owner and contractor records.
03
Automated SLA Breach Alerts
Response-time clocks start the moment an incident is logged. When a threshold is approaching, both sides get a warning. When it breaches, the penalty is automatically calculated and queued.
04
Multi-Vendor Leaderboards
Running parallel contracts across units or regions? Rank contractors head-to-head on availability, MTTR, safety compliance, and cost per MWh — the data you need at renewal negotiation time.
05
Invoice-Ready Performance Reports
Monthly PBM settlement packs generated automatically — base fee, earned bonuses, assessed penalties, supporting event log — all in one exportable document that closes invoices in hours, not weeks.
06
Audit Trail for Every Clause
Every KPI calculation is backed by source data — work orders, sensor readings, technician logs. Regulatory audits, insurance reviews, and contract disputes all resolve against the same evidence.

A Day in the Life of an OxMaint-Enforced SLA
Here is exactly what happens from the moment an incident occurs to the moment it lands on the quarterly performance settlement — all automated, all logged, all auditable.
T + 0 min
Incident logged
Operator or sensor triggers a fault event. Response-time SLA clock starts automatically — visible to contractor and plant manager simultaneously.
T + 45 min
Contractor acknowledgment
Assigned technician accepts the work order via mobile. Acknowledgment timestamp captured. If no ack in 1hr, escalation fires.
T + 3hr
On-site arrival
GPS-validated arrival recorded. Response-time SLA met at 3 hours — within contractual 4-hour threshold. No penalty accrued.
T + 11hr
Repair complete
Work order closed with technician notes, parts used, and root-cause code. MTTR calculated: 11 hours — inside target, no adjustment.
Month-end
Performance settlement
All events aggregated into the PBM invoice packet: base fee, earned bonuses, any liquidated damages, and the underlying event log — emailed to both sides for countersignature.

Frequently Asked
Performance-Based Maintenance Contract Questions
How is a performance-based maintenance contract different from a fixed-fee O&M deal?
Fixed-fee pays a flat rate regardless of performance. PBM ties a meaningful portion of the fee to measured KPIs — availability, MTTR, response time — with bonuses for outperformance and penalties for breach. See real PBM dashboards in a
live demo.
Can OxMaint integrate with the contractor's existing systems?
Yes. OxMaint connects via standard APIs, OPC-UA, and Modbus to DCS, SCADA, historians, and ERP. Contractors get role-based portal access so they use your system without replacing theirs.
Start connecting data in your trial.
Which KPIs should I put into a new PBM contract first?
What happens when contractor and plant data disagree?
With OxMaint there is no disagreement — both sides work from the same immutable event log. Timestamps and readings cannot be edited after the fact, so settlement conversations are about interpretation, not evidence.
See the shared-data model live.
How quickly can a plant move from effort-based to performance-based contracting?
Most plants roll OxMaint KPI tracking in parallel with their existing contract for 60–90 days to baseline current performance. PBM terms then get written into the renewal using real data.
