S&C ELECTRIC PUREWAVE™ DSTATCOM SYSTEM

Complete 15 MVA Utility-Scale Dynamic Reactive Power Compensation System

Imagine your grid more stable, resilient, and future-ready.

This is an exceptional opportunity to acquire a complete 15 MVA utility-grade S&C Electric PureWave™ DSTATCOM (Dynamic Static Synchronous Compensator) system, consisting of two (2) factory-engineered 7.5 MVA containerized units removed from service in operational condition.

Engineered by S&C Electric Company, this is a utility-scale FACTS (Flexible AC Transmission System) solution designed to deliver instantaneous voltage regulation, dynamic reactive power compensation, power factor correction, harmonic filtering, flicker mitigation, and renewable energy grid stabilization.

As utilities continue to modernize their electrical infrastructure and renewable generation expands, DSTATCOM technology has become one of the most effective solutions for maintaining grid stability, improving power quality, increasing transmission capacity, and supporting rapidly changing electrical loads.

Whether you’re expanding renewable generation, constructing a new substation, upgrading transmission infrastructure, developing a battery energy storage project (BESS), powering a hyperscale data center, or improving industrial power quality, this complete OEM-engineered system provides a proven, utility-grade solution ready for its next installation.
