Y'day I had a long discussion with a client on what should be the criteria for selection? is it specific power consumption or energy efficiency? Though of sharing here, we prefer specific power consumption over energy efficiency and here is why: 1. More accurate: Specific power consumption is a more precise metric, as it accounts for the actual output of a process or system. 2. Output-based: It considers the specific output or production volume, making it a more relevant metric for industries with varying output levels. 3. Comparable: Allows for direct comparisons between different systems, processes, or industries with similar output requirements. 4. Actionable: Provides a clear target for energy reduction efforts, as it identifies the specific energy consumption per unit of output. 5. Normalizes energy use: Accounts for changes in production levels, making it a more reliable metric than energy efficiency. 6. Encourages optimization: Focuses on optimizing energy use per unit of output, leading to more efficient processes. 7. Industry-specific: More relevant in industries with specific output requirements, such as cement, steel, or paper production. 8. Benchmarks performance: Enables benchmarking and performance tracking within the same industry or process. 9. Drives innovation: Encourages innovation to reduce energy consumption per unit of output, leading to new technologies and processes. 10. Quantifiable progress: Allows for quantifiable tracking of progress in energy reduction efforts, making it a more effective metric for energy management. Conclusion: Every energy saving project is case specific while energy efficiency is an absolute number. It's not necessary that the operating conditions that are considered while calculating the efficiency is the same while the equipment is in actual operation whereas the specific energy consumption is totally pertaining to that case with everything on actuals. By focusing on specific power consumption, industries and processes can optimize their energy use and reduce their environmental impact more effectively. That's why we prefer Specific power consumption as a criteria in selection of energy saving projects.
