Cachi Hydroelectric Power Station Costa Rica - 102 MW Hydroelectric Plant

Cachi Hydroelectric Power Station is a 102 MW hydroelectric facility located in Costa Rica. As a renewable energy source, it plays a key role in the country's power generation mix, which is heavily reliant on hydropower. The plant is operational and supports Costa Rica's goal of carbon-neutral electricity production. The facility operates as a run-of-river or reservoir-based hydroelectric plant, typical for the region. Costa Rica's regulatory framework for hydropower includes environmental impact assessments and water use permits overseen by the Ministry of Environment and Energy (MINAE). The plant's capacity of 102 MW places it in the medium-to-large scale for the country, contributing significantly to the national grid. Environmentally, the plant provides low-carbon electricity, reducing reliance on fossil fuels. Its operation involves managing water flows from the Reventazón River, which can affect local aquatic ecosystems. The station supports Costa Rica's high renewable energy penetration, often exceeding 98% annually, and helps stabilize the grid during dry seasons when other sources are needed.

The plant's hydroelectric operation has a low carbon footprint but can alter river flow regimes, affecting downstream habitats. Costa Rica's mountainous terrain and abundant rainfall support hydropower, but seasonal variations require careful water management. The facility's location near the Reventazón River means it must balance power generation with ecological flow requirements to protect aquatic biodiversity.
