AGL Energy Limited (AGL.AX) Stock Analysis & Winston Score

AGL Energy is one of Australia's largest electricity and gas companies. It generates power using coal, gas, wind, and solar plants, then sells that electricity and gas directly to homes and businesses across Australia. The company owns some of the biggest power stations in the country, including large coal-fired plants that produce a significant share of Australia's total electricity supply. AGL makes money by selling energy to roughly 4 million customer accounts, charging them for the electricity and gas they use each month. It operates entirely within Australia, making it a domestic utility with little exposure to overseas markets. Its large generation fleet and established customer base give it scale advantages, but its heavy reliance on aging coal plants is a major risk — the company faces rising costs and pressure to retire those plants as Australia shifts toward cleaner energy sources over the coming decade.
