NEPSI

What NEPSI does

NEPSI is a privately-held, for-profit U.S. manufacturer founded in 1995 and headquartered in Queensbury, New York, with a workforce of 11-50 employees. The company designs and builds medium voltage power capacitor banks and harmonic filter banks used for power factor correction, serving industrial and utility customers that need to manage reactive power and mitigate harmonic distortion in their electrical systems. Its products are engineered, project-driven capital equipment rather than commodity electrical components, and the company sells on a quote-based, non-publicly disclosed pricing model typical of bespoke industrial OEMs.

The business remains founder-led, with Paul B. Steciuk serving as Co-Founder, President & Senior Engineer, which concentrates deep domain engineering expertise in the leadership function. No public funding rounds, M&A activity, customer logos, certifications, geographic markets, or product-line details were available in the input data — most of the source blocks were either empty or returned CAPTCHA-blocked pages, leaving the company's competitive positioning, customer base, and financials largely undocumented. The information that is firm indicates a small, mature, niche industrial equipment manufacturer with long-tenured leadership and no observable technology pivots.

Broad incumbents

• Schneider Electric: Global specialist in energy management and automation offering medium voltage capacitor banks, detuned harmonic filters, and active harmonic conditioning systems. Directly comparable product set to NEPSI for power factor correction, but serves customers through integrated electrical distribution and building management platforms.
• ABB: Global electrical equipment giant offering capacitor banks, harmonic filters, and STATCOM/SVC systems through its power quality portfolio. Direct overlap with NEPSI on medium voltage reactive power equipment, but serves customers through a much broader full-line offering including switchgear, transformers, and drives.
• GE Vernova: Power equipment OEM offering capacitor banks and grid power quality solutions through its Grid Solutions business. Competes with NEPSI on medium voltage reactive power and harmonic filter projects but serves customers primarily through large utility and industrial infrastructure contracts.
• Hitachi Energy: Provides FACTS, SVC, and harmonic filtering solutions for HVDC and grid applications. Comparable to NEPSI on the harmonic filtering and reactive power compensation side, but focused on utility-scale transmission projects rather than industrial MV capacitor installations.
• Siemens Energy: Major supplier of power quality solutions including medium voltage capacitor banks, harmonic filters, and STATCOM equipment as part of its Grid Technologies portfolio. Targets the same utility and industrial customers as NEPSI but bundles offerings with transformers, switchgear, and grid integration services.
• Eaton: Multi-national power management company with a substantial electrical equipment business including medium voltage capacitor banks and harmonic filtering solutions under its Power Quality division. Comparable to NEPSI on PF correction products, though typically delivered through wider electrical infrastructure portfolios.
• Hubbell: Manufacturer of electrical products and utility solutions including power quality and capacitor products. Overlaps with NEPSI on power factor correction equipment but positions through broader electrical components and utility hardware portfolios.

Regional players

• Advanced Energy Industries: Provides power conversion and power quality solutions across industrial and renewable energy markets. Adjacent competitor to NEPSI on power conditioning, though broader product focus on power conversion rather than dedicated capacitor bank manufacturing.

Direct peers

• Powell Industries: Custom-engineered manufacturer of medium voltage switchgear, integrated power modules, and capacitor bank assemblies for industrial and utility customers. Closely comparable to NEPSI in terms of custom MV power equipment manufacturing and project-based sales motion to similar end markets.
• Myron Zucker: Specialty manufacturer of medium voltage and low voltage capacitor banks, harmonic filters, and power factor correction equipment serving industrial and utility customers. Closest head-to-head competitor to NEPSI given its similar niche specialization in engineered MV capacitor bank solutions.
