Garzas 1 Hydroelectric Power Plant, Puerto Rico | United States

Garzas 1 is a hydroelectric power plant located in Puerto Rico, United States, with a capacity of 7.2 MW. The facility is owned and operated by PREPA, the Puerto Rico Electric Power Authority, and is currently operational. As a small-scale hydroelectric plant, it contributes to the island's renewable energy generation. The plant operates under the regulatory framework of the United States, including the Clean Air Act and related environmental standards. Hydroelectric power is a low-emission technology, and Garzas 1 likely uses run-of-river or reservoir-based generation typical for its size. The plant's capacity places it in the small-scale category for hydroelectric facilities. Garzas 1 plays a role in diversifying Puerto Rico's energy mix, which has historically relied on fossil fuels. By generating electricity from hydropower, the plant helps reduce greenhouse gas emissions and supports grid stability in the region. Its operation aligns with broader efforts to integrate renewable energy into the island's power system.

As a hydroelectric plant, Garzas 1 produces electricity with minimal direct emissions of CO2, SOx, or NOx, offering environmental benefits over fossil fuel-based generation. The facility's location in Puerto Rico, an island with high rainfall, supports hydropower generation. However, hydroelectric projects can affect local aquatic ecosystems and water flow regimes. The plant's small capacity limits its overall environmental footprint.
