Pillars of Service
Three integrated pillars. One unified mission.
IIS delivers infrastructure solutions across the full asset lifecycle through three complementary service pillars.
Power Generation Engineering & Life-Extension
We support fossil, combined-cycle, hydroelectric, and renewable-integrated power plants through engineering analysis, system upgrades, and equipment refurbishment. Our experience spans boilers, balance-of-plant, auxiliary equipment, piping, tanks, pumps, and rotating machinery.
- Power-plant system upgrades
- Equipment refurbishment and overhaul
- Piping, tank, and auxiliary system repairs
- Reliability and performance engineering
- Outage planning and in-service execution
Renewable Energy & Grid Resilience
IIS designs and supports renewable energy and resiliency projects including solar PV, battery energy storage, and EV charging infrastructure. We integrate these systems into existing facilities to improve resilience, reduce emissions, and support long-term sustainability goals.
- Solar PV design and installation
- Battery energy storage systems (BESS)
- EV charging infrastructure
- Renewable integration with existing plants
- Engineering analysis and commissioning
In-Service Composite Repair & Structural Reinforcement
Our advanced composite systems rehabilitate aging, corroded, or leaking infrastructure while assets remain in service. Composite repairs restore and often exceed original design strength, provide corrosion resistance, and function independently of the host pipe—reducing replacement costs by up to 70%.
- High-pressure fluid-fill electric & mechanical piping
- Transmission and distribution infrastructure
- Tanks, vessels, and structural components
- Up to 70% cost savings vs replacement
- 30–50+ year service life · significant carbon reduction
