Concentrated Solar Power plants are among the most mechanically complex renewable energy assets on the planet — thousands of heliostats tracking the sun, heat transfer fluids circulating at 400°C, and molten salt storage systems that can solidify and destroy piping if thermal management fails for even a few hours. Most CSP O&M teams understand the technology deeply but operate from fragmented PM records, manual heliostat tracking logs, and reactive maintenance workflows that leave millions in generation capacity on the table. OxMaint's CMMS brings the same data discipline to CSP that drives performance in conventional thermal plants — with PM automation, salt loop tracking, and receiver maintenance records built for the unique demands of solar thermal generation.

System Overview
Five CSP Subsystems. One Maintenance Platform.
OxMaint manages PM programs across every major CSP subsystem — from the heliostat field to the power block — with asset-specific templates, mobile field access, and complete service documentation.
01
Heliostat Field
Mirror cleaning schedules, drive actuator PM, tracking calibration records, soiling rate trending, and broken mirror replacement tracking — across fields of 10,000+ heliostats.
02
Central Receiver / Tower
Receiver tube inspection records, hotspot monitoring logs, coating condition assessment, high-temperature joint inspection, and annual thermal performance baseline testing.
03
Molten Salt Loop
Salt pump PM, heat trace system inspection, freeze protection records, salt quality analysis, valve operation logs, and thermal expansion joint inspection — all tracked against regulatory and OEM requirements.
04
Steam Generator / HX
Tube bundle inspection, fouling assessment, pressure test records, steam drum inspection logs, and feedwater quality monitoring — with complete work order history for ASME inspection compliance.
05
Power Block
Turbine PM schedule, condenser tube inspection, cooling tower treatment logs, lube oil analysis, and electrical equipment PM — the same thermal power plant maintenance discipline applied to CSP's power block.
Critical Risk: Molten Salt Freeze Events — What CMMS Records Prevent
290°C
Salt Freeze Point
Below this temperature, molten salt solidifies — potentially blocking and bursting pipes, destroying pumps, and requiring weeks of repair at costs exceeding $30M.
4-hr
Heat Trace Response Window
When grid power fails or heat trace systems fault, the response window before freeze risk begins is measured in hours — not days. CMMS records missed heat trace PM inspections that create this vulnerability.
100%
PM Completion Required
Unlike other O&M programs where 90% PM completion is acceptable, heat trace system inspections require zero gaps. OxMaint flags any incomplete PM in this category before it creates exposure.
Platform Capabilities
How OxMaint Manages CSP Maintenance Programs
CSP plants require maintenance disciplines borrowed from multiple industries — solar, thermal power, chemical processing, and heavy industrial. OxMaint unifies them. See it in action — book a 30-minute demo.
01
Heliostat-Level Asset Tracking
Each heliostat registered as an individual asset with GPS coordinates, drive serial numbers, mirror panel count, and last cleaning date. Cleaning crew routes auto-generated by soiling rate zone, not arbitrary schedules.
02
Salt Loop PM with Freeze Protection Priority
Heat trace inspection, salt pump lubrication, and freeze protection system tests all carry elevated priority flags in OxMaint — work orders cannot be closed without documented completion. Overdue alerts escalate automatically to plant management.
03
Receiver Inspection and Hotspot Records
Thermal imaging results, tube condition assessments, and coating degradation records stored against receiver asset ID with trend visualization. Accelerating degradation triggers corrective work orders before the next planned inspection window.
04
Outage Planning Across All Subsystems
Annual outages at CSP plants involve coordinated maintenance across heliostats, the salt loop, heat exchangers, and the power block simultaneously. OxMaint builds outage work packages, checks parts availability, and tracks progress against completion targets in real time.
05
Mobile Field Access Across the Heliostat Field
Field technicians covering square kilometers of heliostat field need offline-capable mobile access — not a desktop CMMS. OxMaint's mobile app works offline, syncing records when connectivity is restored. No paper, no transcription errors.
Purpose-Built for Complex Renewables O&M
CSP Demands Precision Maintenance. OxMaint Delivers It.
Heliostat calibration drift, salt loop degradation, and receiver hotspots compound silently until they become forced outages. OxMaint's CMMS gives CSP operators the tools to catch every issue on a schedule — not after an alarm.

Frequently Asked Questions
CSP Maintenance Programs — What Teams Ask Most
Can OxMaint manage individual heliostat assets at scale — 10,000+ units?
Yes. OxMaint supports large asset registries at heliostat-field scale with GPS coordinates, grouped zone assignments, and bulk PM deployment. Cleaning routes auto-generate by zone, maintenance history is stored per heliostat, and defect tracking (broken mirrors, drive faults) is managed individually without overwhelming the interface.

How does OxMaint handle freeze protection PM for molten salt systems?
Heat trace inspection, freeze protection valve operation tests, and salt pump readiness checks are flagged as safety-critical in OxMaint. Work orders auto-generate on schedule, cannot be bypassed without management escalation, and overdue alerts fire immediately. Full audit trail maintained for insurance and regulatory review.
See safety-critical PM management in a demo.
Does OxMaint work in areas of the heliostat field with poor connectivity?
Yes. OxMaint's mobile app supports offline mode — technicians load their work orders before entering the field and complete them without connectivity. Records sync automatically when the device reconnects. No paper logs, no transcription step, no data loss.
Can OxMaint integrate with our SCADA and DCS systems for CSP data?
OxMaint connects to SCADA, DCS, and plant historian systems via standard APIs — importing operational parameters, alarm data, and run-hour counters directly into asset records for PM trigger automation and failure trend analysis.
Discuss your integration setup in a demo.
How does OxMaint support annual CSP plant outage planning?
OxMaint builds outage work packages from PM templates across all subsystems — heliostat, receiver, salt loop, steam generator, power block — checking parts availability, generating procurement requests for shortfalls, and tracking progress against completion milestones in a live outage dashboard accessible to all stakeholders.
