H 4 Hydroelectric Power Plant, Texas | Renewable Energy Facility

H 4 is a hydroelectric power plant located in Texas, United States, with a capacity of 2.4 MW. It is owned and operated by the Guadalupe Blanco River Authority, a public utility serving the region. As a small-scale hydro facility, it contributes to the local renewable energy mix. The plant operates under the regulatory framework of the US Federal Energy Regulatory Commission (FERC) for hydropower licensing and the Clean Water Act for water quality. Hydroelectric plants like H 4 typically use run-of-river or impoundment technology to generate electricity without direct fuel combustion, resulting in low emissions. H 4 plays a role in supporting grid stability and providing clean energy to the surrounding communities. Its small capacity makes it suitable for local distribution, reducing transmission losses. The plant's operation aligns with Texas's growing emphasis on renewable energy sources.

Hydroelectric power generation has a low carbon footprint compared to fossil fuel plants, but can affect local aquatic ecosystems through altered water flow and fish passage. H 4's small capacity likely minimizes these impacts. The plant is situated in a rural area of Texas, reducing proximity to dense populations. Its operation under FERC regulations ensures compliance with environmental standards for water quality and habitat protection.
