What Clifford Power Systems does
Clifford Power Systems, Inc. is a privately held industrial power generation company founded in 1985 in Tulsa, Oklahoma by brothers Ken and Tom Clifford. The company operates as the sole authorized Generac Industrial Energy dealer across its markets and provides a complete power-generation lifecycle: equipment sales (Generac stationary generators from 10 kW to 3.25 MW, mobile generators, automatic transfer switches, light towers), installation oversight, planned maintenance and repair services on 10,000+ generator systems across all makes and models, 24/7 emergency response, mobile generator rentals (25 kVA to 2,000 kVA), and parts supply with $1.5 million in inventory and same- or next-business-day delivery. The company has expanded its offerings to include Generac Stationary Battery Energy Storage Systems (BESS) and integrated microgrid solutions combining generators, battery storage, and intelligent controls.
Clifford Power operates 9 branch locations across 5 states (Oklahoma, Kansas, Texas, Arkansas, and Missouri) with 165+ employees, holding the position of the largest independent generator company in the south-central U.S. The customer base spans hospitals and healthcare systems, data centers, telecommunications providers, food processing facilities, universities, utilities, railroads, airports, municipal governments, and event organizers. Revenue is generated through three primary streams: one-time equipment sales, recurring planned-maintenance service contracts, and usage-based rental income, supplemented by parts sales. The go-to-market is enterprise field sales with dedicated sales representatives per territory, supported by direct-to-customer marketing channels including case studies, training programs (operator training, Professional Development Seminar Series, Engineering Symposium with Generac), and trade publication features.
The company is led by President Jeremy Lewis, who joined as a shop technician in 1994 and was appointed president in 2017, alongside VP of Operations Rhonda Mills and VP of Sales Stephanie Benson. No private equity, venture capital, or parent company involvement is indicated in the source data, and Clifford Power has remained founder-controlled since 1985.
