Overview
Donnells is a 72 MW hydroelectric power plant in California, United States, operated by Oakdale & South San Joaquin Irrigation District. It generates renewable energy from hydropower.
Donnells is a hydroelectric power plant located in California, United States, with an installed capacity of 72 MW. The facility is owned and operated by the Oakdale & South San Joaquin Irrigation District, contributing to the region's renewable energy portfolio. As a hydroelectric facility, Donnells operates without direct fuel combustion, resulting in minimal air emissions compared to fossil fuel plants. The plant's technology relies on water flow to generate electricity, aligning with clean energy standards under the US Clean Air Act. In California, hydroelectric plants are subject to state and federal regulations, including the Federal Energy Regulatory Commission (FERC) licensing requirements. The plant plays a role in supporting grid stability and providing renewable energy to the local area. Its capacity of 72 MW places it in the small-to-medium scale range for hydroelectric facilities. The operational status is active, ensuring continued contribution to the region's energy mix.
Environmental context
Hydroelectric power generation has a low carbon footprint but can affect local aquatic ecosystems. The Donnells plant is situated in a mountainous region of California, where water resources are managed for both energy and irrigation. Operations must balance power generation with downstream water needs and fish habitat considerations. The facility's environmental impact is primarily related to water flow management rather than air emissions.
Frequently asked questions
