AGL

AGL is an acronym with several distinct meanings, depending on the context. In business and industry, it most often refers to AGL Energy Limited, an Australian energy company. In aviation and meteorology, AGL stands for above ground level, a height reference relative to the local terrain rather than sea level.

AGL Energy Limited is a major Australian energy retailer and generator. Its historical roots trace to the Australian Gas Light Company, established in 1837 in Sydney as the first gas utility in Australia. Over time, the organization expanded into electricity generation and gas retail, adopting the AGL name for its modern operations. Today, AGL Energy is a prominent supplier of electricity and gas to residential and business customers in Australia and operates a mix of generation assets and energy services. It is listed on the Australian Securities Exchange.

Above ground level is an altitude designation used in aviation, construction, meteorology, and related fields. It expresses height above the actual ground surface at a given location, as opposed to mean sea level (MSL). AGL is terrain-dependent and is commonly used to describe aircraft clearance margins during takeoff and landing, obstacle clearance, and certain weather or engineering assessments.

Other uses of AGL may occur in organizations or industry phrases specific to particular regions or fields. Without context, AGL typically requires clarification to determine which meaning is intended.
