IPS specializes in single-source turnkey solutions for hydroelectric generators, including repair, field and engineering services, and the manufacture of stator coils up to 15 kV. Our coast-to-coast coverage means we can concentrate more experience and resources than local repair shops, with response times and cost advantages that larger, multi-national service providers can’t match.
We service and repair all brands of hydroelectric generators. Our experienced field service specialists offer a full spectrum of electrical tests, including EL CID, corona probe, MCE, polarization index, surge, hi-pot and partial discharge, and they’re backed by deep technical experience. We also provide engineering evaluations, uprate and design services, manufacturing and installation, to give you more power and reliability in the same footprint.
Our in-house coil manufacturing gives us complete control of quality and delivery, while providing customers with a single point of accountability. We offer a full range of rewind technologies up to 15 kV, including both engineered insulation systems and fully cured B-stage hard coils. IPS regional service centers have extensive in-shop experience with large-scale projects — we have the lifting capacity and equipment to handle big jobs, including large shaft manufacture and repair. Our capabilities also include the manufacture of new stator cores, bearing rebabbiting, exciter repair and complete machining services.

In-house stator coil manufacturing
IPS Shreveport dedicated clean winding room with 12' VPI
EL CID testing on hydrogenerator (39 MVA / 13.2 kV)
IPS PennCoil is a leading manufacturer of stator coils for hydro generators. Our experienced technicians use state-of-theart equipment in a 73,000 sq. ft., ISO 9001: 2008 with design, registered manufacturing facility. We manufacture stator coils up to 15 kV, and rewind and refurbish wire- and edge-wound rotor coils.
Field services
Our coast-to-coast service centers give you local responsiveness, backed by massive regional and national resources. IPS dedicated field service technicians conduct IEEE-approved electrical tests, cryogenic cleaning, vibration analysis and other predictive and preventive services for hydro generators. We offer complete disassembly and repair of generators, including on-site stator and rotor rewinds, plus repair and replacement for bearings, shafts and exciters.
Engineering - uprate and design services
Many of our customers have older hydro generator designs which provide limited power production. We can optimize your equipment and components, using state-of-the-art materials and processes, to increase power generation and reliability in the same footprint. If blueprints are unavailable, we can re-engineer, then design, manufacture and install new components.
Big Iron machining services for hydro shafts and brake rings
IPS Portland has extensive experience with “Big Iron” machining services for hydro main shafts and brake rings. We can remove old sleeves, manufacture new ones, and then split and weld them into place. We also machine and polish bearing fits, and clean detail and re-cut flange faces. Like every IPS job, these projects meet OEM spec or better, and are documented and validated.
