World Power Plants

The Poe hydroelectric power generation facility, with a capacity of 142.8 MW, is positioned as the 1734th largest plant in the United States, reflecting its modest yet vital contribution to the national energy portfolio. Commissioned in 1958 and operated by Pacific Gas & Electric Co., this facility is part of a larger hydroelectric network that includes notable nearby plants such as the Edward C. Hyatt Hydro with a robust capacity of 644.1 MW and the Colgate Hydro at 315 MW. Despite its relatively small size compared to these giants, Poe plays an essential role in the regional energy grid, especially considering that it contributes approximately 0.01% of the United States' total capacity of 1,386,385 MW, where gas is the dominant fuel source. The facility’s hydroelectric generation method, which harnesses the flow of water to produce electricity, positions it among the 142nd largest hydro plants in the country, a critical category as the U.S. continues to explore renewable energy options. In the local context, Poe's output is complemented by several other hydro facilities within a close radius, enhancing the reliability and sustainability of the local grid. The collective contributions of these plants significantly support the region's energy needs, particularly during peak demand periods when hydroelectric generation can offset the fluctuations inherent in gas and other fuel sources. As the United States moves toward a more diversified energy mix, the operational longevity of Poe serves as a testament to the viability of hydro power in providing clean and renewable energy. This facility not only contributes to reducing greenhouse gas emissions but also plays a crucial role in water resource management, showcasing the multifaceted benefits of hydroelectric energy. The continued operation and potential upgrades at Poe could further enhance its efficiency and output, reinforcing its significance within the evolving landscape of American energy production.
