Every megawatt counts. When a critical Siemens component fails — inside a gas turbine combustor, a HV switchgear bay, or a SIPROTEC protection relay — the procurement clock starts immediately and the margin for supplier mistakes shrinks to zero.
Automabuy operates as a dedicated Siemens Energy Spare Parts Supplier — covering the full span of Siemens Energy’s installed base, from SGT aeroderivative and heavy-duty gas turbines to HV gas-insulated switchgear, MV circuit breakers, SIPROTEC 5 protection systems, and generator excitation hardware. We source genuine, tested components for both current-production equipment and legacy systems that predate the 2020 Siemens Energy spinoff, backed by traceable documentation and delivery schedules built around your outage calendar.
| ⚡ Quick Answer Automabuy supplies Siemens Energy spare parts across gas turbines (SGT-100 to SGT-8000H, 2–593 MW), aeroderivative units (SGT-A05 and SGT-A35 with 50M+ operating hours across 900+ units), HV/MV switchgear, power transformers, SIPROTEC 4/5 relays, SICAM RTUs, and generator excitation systems — including hard-to-source legacy components — with full documentation and worldwide delivery. |
The Siemens Energy Installed Base — and the Sourcing Gap Nobody Talks About
Siemens Energy became an independent company in September 2020, separating from Siemens AG with a portfolio spanning gas turbines, steam turbines, generators, HV transmission equipment, and grid control technology. That transition created a catalogue discontinuity still affecting procurement teams today — part numbers tied to pre-spinoff Siemens Power Generation product families, documentation split across two corporate entities, and an OEM supply chain that has reorganized its distribution model since independence.
Plants operating older Siemens industrial gas turbines — SGT-100, SGT-300, or SGT-400 frames commissioned in the early 2000s — regularly encounter OEM channels quoting extended lead times or rerouting enquiries toward costly Long Term Programs rather than individual component supply. The same pattern appears in HV switchgear maintenance: a bay built on an older Siemens GIS frame needs a replacement drive mechanism or vacuum interrupter, and standard distribution channels either don’t hold the part or price it at a level reflecting scarcity rather than manufacturing cost.
This is precisely the gap Automabuy fills as a specialist Siemens Energy Spare Parts Supplier. Our sourcing relationships reach into surplus inventory pools, refurbishment networks, and cross-reference databases that generic electrical distributors don’t access — built specifically to serve energy facilities whose equipment has aged beyond the OEM’s commercial interest in stocking individual replacement components.
Complete Siemens Energy Spare Parts Coverage
From SGT-800 first-stage rotor blades that can be axially removed for on-site exchange, to SIPROTEC 5 communication cards that force full chassis replacement if you can’t isolate the sub-component — Automabuy stocks and sources across the entire equipment tree.

What Makes Automabuy the Right Siemens Energy Spare Parts Supplier for Your Facility
The difference between a specialist and a generic catalogue reseller surfaces the moment you submit an unusual part request. At Automabuy, that difference is built into how we operate:
✔ SGT hot section sourcing — combustion hardware and blade sets verified for specific turbine frame revisions, not generic cross-referenced equivalents
✔ Legacy GIS coverage — tested surplus operating mechanisms and interrupters for older 8DN and 8DQ bays where current-production equivalents no longer exist
✔ SIPROTEC sub-component supply — individual I/O cards, communication modules and power supplies sourced separately, eliminating costly full relay chassis replacement
✔ Transparent condition grading — new, refurbished, or repaired clearly stated at quotation, no category blending to obscure hardware condition
✔ Energy-sector documentation standard — material certificates, dimensional conformance records, test reports and export paperwork prepared as part of every order
✔ Outage-aligned delivery — lead times confirmed at quotation against actual stock position, parts scheduled to arrive within your maintenance window

Power Generation Sectors Automabuy Serves
Gas Turbine Power Stations & Combined Cycle Plants
SGT-800 frames offer up to 60,000 equivalent operating hours between major overhauls. SGT5-8000H units run baseload duty at the highest efficiency ratings in the heavy-duty segment. Both platforms need scheduled hot section replacements against operating hours — not against OEM convenience. Automabuy supplies burner modules, compressor hardware, and combustion system components on timelines maintenance planners can anchor to.
Offshore Oil & Gas Platforms & Pipeline Stations
The SGT-A35 has built more than 50 million operating hours across over 900 units in oil and gas service — offshore platforms, pipeline compression trains, and LNG facilities worldwide. Its modular gas generator design supports on-site core exchange, but only when replacement modules arrive in pre-verified, ready-to-install condition before the planned window opens. Automabuy sources and conditions SGT-A35 components to meet that schedule.
Transmission Substations & Grid Infrastructure
Siemens HV switchgear bays carry decades of service life. A failed drive mechanism or damaged busbar in an aging 8DN or 8DQ installation has no clean OEM supply path today. Automabuy specifically maintains access to legacy HV switchgear components from tested, decommissioned installations — the sourcing path that substation maintenance managers actually need, not the one that’s still listed in a catalogue.
Industrial Cogeneration & Decentralized Generation
Cement plants, chemical facilities, and steel mills running SGT-100 to SGT-400 frames for combined heat and power often find that the OEM relationship has shifted from active supply into a support mode that pushes Long Term Program commitments over individual component sales. Automabuy provides direct individual component access — the right part, at the right specification, without a program contract attached.
Frequently Asked Questions
Does Automabuy supply hot section parts for SGT industrial gas turbines?
Yes — combustion liners, flame tubes, first-stage rotor blades, transition pieces, and fuel nozzles are sourced for SGT-100 through SGT-800 and larger heavy-duty frames, with part verification against the specific turbine revision before quotation.
Can Automabuy find parts for Siemens equipment predating the 2020 spinoff?
Yes. Legacy Siemens gas turbine and switchgear frames catalogued before the spinoff are specifically covered through surplus and refurbishment networks — including models where the current Siemens Energy distribution channel no longer holds individual component stock.
What documentation comes with each order?
Material certificates, condition reports, dimensional conformance records, packing documentation, and export paperwork including certificates of origin — prepared as standard for every order, particularly for buyers operating under ISO 55000 or IEC 61850 compliance frameworks.
Can individual SIPROTEC modules be sourced without replacing the full relay?
Yes. SIPROTEC 4 and SIPROTEC 5 I/O extension modules, communication interface cards, and power supply boards are sourced and tested individually at Automabuy — a meaningful cost saving over full relay unit replacement when a single module has failed.
How long does international delivery take?
In-stock components typically dispatch within two to five business days with full export documentation. Specialist-sourced or conditioned items take two to four weeks — timeline confirmed at quotation, not revised after payment.
Which regions does Automabuy ship to?
Worldwide — power stations across India, the GCC, Southeast Asia, Africa, and Europe receive orders with customs documentation, certificates of origin, and logistics coordinated from New Delhi.
