Samarra Barrage Hydroelectric Power Plant, Iraq | 75 MW Facility

Samarra Barrage is a hydroelectric power plant located on the Tigris River in Iraq, with an installed capacity of 75 MW. The facility is owned and operated by Iraq's Ministry of Water Resources and is currently operational. As a hydroelectric plant, it harnesses the flow of the river to generate renewable electricity, contributing to Iraq's energy mix. The plant operates under Iraq's national regulatory framework for water resources and energy generation. Hydroelectric power in Iraq is a relatively small but important part of the country's power sector, which is dominated by fossil fuels. The Samarra Barrage's capacity of 75 MW places it in the small-to-medium scale for hydroelectric plants globally, but it is a significant asset for local grid stability and irrigation control. Environmentally, hydroelectric power is a low-carbon energy source, but it can impact river ecosystems and water flow. The Samarra Barrage also serves flood control and irrigation purposes, making it a multi-purpose infrastructure. Its operation is subject to seasonal water availability, which can affect power output. The plant supports rural electrification and reduces reliance on thermal power in the region.

Hydroelectric power generation at Samarra Barrage produces minimal direct emissions, but the dam alters the Tigris River's natural flow, affecting downstream sediment transport and aquatic habitats. The reservoir may contribute to methane emissions from decomposing organic matter. Iraq's arid climate and water scarcity make the barrage's water management role critical, balancing power generation with agricultural and domestic water needs.
