World Power Plants

The San Miguel power plant, located in Texas, United States, is a significant coal-fired power generation facility with a capacity of 410 MW. Owned and operated by San Miguel Electric Coop Inc., this plant has been an integral part of the local energy landscape since it began operations in 1982. Situated at coordinates 28.7044° N latitude and 98.4775° W longitude, San Miguel plays a crucial role in supplying electricity to the regional grid, ensuring that local communities have access to reliable energy. As a coal-fired power plant, it utilizes subcritical technology, which allows for the combustion of coal to generate steam that drives turbines for electricity production. While coal has been a traditional source of energy, the significance of the San Miguel plant is currently being evaluated in the context of changing energy policies that prioritize cleaner sources of energy. In Texas, where energy generation is diverse, the San Miguel facility remains important for base-load power generation, providing stability to the grid, especially during peak demand periods. Although the global trend is shifting towards more sustainable energy practices, San Miguel's operational history and existing capacity continue to contribute to the state's energy needs, demonstrating the complex landscape of energy generation in the United States.
