Inefficient operation of cooling water systems can lead to increased energy consumption and reduced power output, especially during peak demand periods in hot weather. This inefficiency not only impacts the operational costs of power plants but also poses challenges in meeting environmental regulations. For plants in India, adhering to water consumption limits of 3.5 m³/MWh for older plants and 2.5 m³/MWh for newer ones is essential to avoid regulatory penalties. Failure to optimise these systems could also strain water resources, particularly in regions already facing water scarcity.
