Overview
Industrial generator sets (alternators) are the electrical half of a power generation system — converting rotational shaft power from a prime mover (steam turbine, gas turbine, diesel engine) into AC electricity. Our alternators are synchronous machines with brushless excitation, Class H insulation, and IP23 or IP54 enclosures for harsh industrial environments. Available in low-voltage (400V, 480V, 690V) and medium-voltage (3.3 kV, 6.6 kV, 11 kV, 13.8 kV) configurations to match plant distribution systems. Typically supplied as a matched set with a steam turbine for cogeneration plants, or as standalone replacement alternators for existing prime movers. Common applications: sugar mill cogeneration, paper mill captive power, palm oil plant power export to grid, independent power producers.

What Determines Your Quote
Every quote is engineered to your operating requirements. Pricing depends on:
- Configuration: capacity, flow rate, head pressure, motor size, voltage/phase, materials of construction
- Certification tier: WRAS-cert vs commercial-grade, ASME stamping, IP rating for panels
- Delivery region: nationwide (Metro Manila, Luzon, Visayas, Mindanao); freight varies by destination
- Installation scope: supply-only, supply + mechanical install, or full turn-key with commissioning
- Payment structure: milestone terms tailored to project timeline (typically 40/30/20/10 for engineered scopes; 70/30 for equipment supply)
- Tax status: 12% VAT applies to VAT-registered buyers; Zero-VAT available for eligible PEZA / SBMA locators and exporters

Frequently Asked Questions
What certifications come with the generator and alternator set?
Every generator and alternator set we supply carries CE marking and is manufactured under an ISO 9001:2015 certified quality system, with the machines designed and tested to IEC 60034, the core international standard for rotating electrical machines. IEEE 115 and NEMA MG-1 compliance are also referenced in the standard specification, which matters when your electrical consultant is working to North American plant standards. Every shipment includes material test certificates and factory inspection reports, along with the test records for the brushless excitation system, automatic voltage regulator, and the PT100 temperature sensors fitted to the stator and bearings. As your industrial supply partner, we compile the complete certificate and test file into one handover package so your compliance, permitting, and grid-connection paperwork is ready from day one. If your utility or lender requires specific type-test documents, confirm the list with us at inquiry stage.
What is the standard lead time for a generator or alternator set?
Generator and alternator sets in this class are built to order, so plan for a typical lead time of 90 to 120 days from confirmed order, depending on the rating, voltage class, and enclosure you specify. Low-voltage machines in common ratings sit toward the shorter end, while medium-voltage units at 6.6 kV and above, or alternators supplied as a matched set with a steam turbine, generally need the full window. The exact schedule for your configuration is confirmed in the written quotation, which we return within 3 to 5 business days of receiving your electrical requirements. If the alternator is part of a larger cogeneration project, we align its manufacturing schedule with the turbine so both arrive as a matched, tested set rather than in mismatched deliveries. We respond to initial inquiries within 1 business day, so early engagement protects your project timeline.
Do you deliver generator sets to Luzon, Visayas, and Mindanao?
Yes, delivery is nationwide: Metro Manila, all Luzon provinces, the Visayas, and Mindanao, including regular shipments into SBMA, Clark, and PEZA industrial estates where captive power and grid-export projects are concentrated. Alternators in the megawatt class travel as heavy project cargo, so our delivery scope covers port handling, permits for overweight trucking where required, and coordination of offloading at your site, including crane requirements if you take the supply-plus-install option. During quotation we ask for your site access details, road width, gate clearance, and laydown space, so the logistics are priced accurately upfront instead of appearing as extras later. For Visayas and Mindanao destinations, sugar mills, palm oil plants, and island power producers among them, we schedule around vessel sailings and confirm the delivery window in the written quotation. Getting the machine safely to your switchyard is part of our job, not yours.
Is installation included with the generator set, or is it supply-only?
Both options are available and quoted separately so you can compare them line by line. Supply-only delivers the alternator with its documentation package to your site, leaving mechanical installation and electrical termination to your own contractors, which suits plants with experienced in-house teams. Supply-plus-install adds mechanical placement and alignment to the prime mover, coupling fit-up for single-bearing or double-bearing configurations, supervision of electrical termination at low or medium voltage, and commissioning support covering excitation setup, AVR tuning, and protection checks before first synchronization. Alignment quality between the alternator and its turbine or engine directly determines vibration and bearing life, so for matched cogeneration sets we recommend at least commissioning supervision even if your contractor handles the physical work. State your preferred scope at inquiry and the written quotation, returned in 3 to 5 business days, will show both scopes as separate priced items.
What warranty does the generator or alternator set carry?
Each machine is covered by a manufacturer warranty that we pass through to you in full, with the warranty certificate included in the delivery file together with the material test certificates and factory inspection reports. Because these alternators span a wide range from 100 kW to 30 MW across low-voltage and medium-voltage classes, the specific warranty term and conditions for your unit are confirmed in the written quotation rather than stated as a single generic figure. Coverage applies to the stator, rotor, brushless excitation system, and AVR when the machine is operated within its rated conditions and maintained per the manual, with the fitted PT100 temperature sensors providing the operating records that make warranty discussions straightforward. We act as your single point of contact for any claim, coordinating directly with the factory on your behalf. Extended warranty and spare parts packages can be quoted alongside the machine.
Can you customize the alternator to a non-standard specification?
Yes: these machines are configured to order across the full range of 100 kW to 30 MW, and matching the alternator to your plant is standard practice rather than a special request. You choose the voltage to suit your distribution system, from 400V, 480V, and 690V low-voltage options up to 3.3 kV, 6.6 kV, 11 kV, and 13.8 kV medium-voltage classes, at 50 Hz or 60 Hz. Speed and pole count (2-pole, 4-pole, or 6-pole at 1,500 to 3,600 rpm) are matched to your prime mover, with single-bearing or double-bearing construction and IP23 or IP54 enclosures depending on the installation environment. Replacement alternators for existing turbines or engines are also engineered to match legacy mounting and coupling dimensions. Send your electrical single-line, prime mover details, and site conditions, and we return an engineered proposal with the written quotation in 3 to 5 business days.
