Oklahoma City possesses a robust infrastructure network scaled for its massive land area. Electricity is primarily provided by OG&E (Oklahoma Gas & Electric), with energy sourced from natural gas, coal, and a rapidly expanding portfolio of wind power.
The city's water and wastewater services are managed by the local government, drawing fresh water from a network of regional lakes including Lake Hefner, Lake Overholser, and long-distance pipelines from southeastern Oklahoma.
Telecommunications infrastructure is highly developed. High-speed broadband and fiber-optic internet are widely available through providers like AT&T, Cox Communications, and OEC Fiber. 5G cellular networks from all major national carriers blanket the metropolitan area.
