Garland boasts a strong, self-reliant infrastructure system. Uniquely, the city operates its own electric utility, Garland Power & Light (GP&L), which serves a large portion of the city's residents and businesses, while other areas are served by the deregulated Texas grid (ERCOT) via providers like Oncor.
Water and wastewater services are managed by the city, with water primarily sourced from the North Texas Municipal Water District (NTMWD), which draws from surrounding reservoirs including Lake Ray Hubbard. Garland is fully equipped with modern telecommunications infrastructure, offering high-speed broadband, fiber-optic internet, and comprehensive 5G cellular coverage through major national providers like AT&T, Spectrum, and Frontier.
