About
Atom Power is a North Carolina-based energy technology company that developed the world's first commercially available, UL-listed digital solid-state circuit breaker — the Atom Switch. Unlike traditional electromechanical breakers, the Atom Switch uses semiconductor technology to open and close circuits in microseconds, enabling programmable load management, real-time power monitoring, and significantly improved safety characteristics. The platform integrates hardware and software to deliver intelligent energy management for EV charging infrastructure, multi-family residential buildings, commercial facilities, and campus environments.

About
Quanta Services, Inc. is a Houston, Texas-based specialty contractor — publicly traded on the New York Stock Exchange (NYSE: PWR) as an S&P 500 Industrials component — providing comprehensive infrastructure services for the electric power, gas pipeline, renewable energy, and communications industries through a network of operating units in North America, Latin America, Australia, and internationally through approximately 52,000 employees. In fiscal year 2024, Quanta Services reported revenues of $23.6 billion (+13% year-over-year), with the Electric Power Infrastructure Services segment (power line construction, substation installation, storm restoration, energized work) generating $16.2 billion and the Renewable Energy Infrastructure Services segment (solar and wind farm BOP — balance of plant construction, grid connection, battery storage installation) generating $4.2 billion. CEO Duke Austin has positioned Quanta as the infrastructure services company most directly benefiting from the electrification of the economy: every new electric vehicle charging station requires Quanta-type electrical contractor work (panel upgrades, conduit installation, transformer additions), every new data center requires utility-grade substation construction and high-voltage transmission interconnection, and every utility's grid modernization program requires storm hardening, line replacement, and automation installation — all work that Quanta's operating units execute under multi-year master service agreements with utility customers. Quanta's 2023 acquisition of Cupertino Electric (California-based industrial and data center electrical contractor) and ongoing acquisitions of regional utility contractors expand Quanta's geographic footprint and service capability in the data center electrical construction and renewable energy transmission sectors.
