Executive Summary & Key Takeaways

What it means

  • The notification amends the Ministry of Power's notification S.O. 185(E) dated January 12, 2009, concerning energy efficiency standards for transformers.
  • The amendment extends the validity of existing energy efficiency norms and updates the loss parameters for transformers.

Key Changes

  • Table 2 is amended by replacing the year '2023' with '2024', effectively extending the applicability of the existing standards.
  • Table 3, which specifies the standard losses in watts for transformers up to 11 kV class (for ratings above 200 kVA), is replaced with a new table.
  • The new Table 3 provides updated loss values for transformers with star ratings from 1 Star to 5 Star, valid from July 1, 2017, to December 31, 2024.
  • The table specifies losses at 50% and 100% load conditions for different kVA ratings (250, 315, 400, 500, 630, 1000, 1250, 1600, 2000, and 2500) and impedance percentages.

Impact Analysis

Transformer Manufacturers

  • Action Item: Review existing transformer designs and manufacturing processes to ensure compliance with the new Table 3 loss values. Obtain necessary certifications for compliance.

Electricity Distribution Companies (DISCOMs)

  • Action Item: Update procurement specifications to mandate compliance with the revised energy efficiency standards for transformers. Monitor the performance of newly procured transformers.

Large Industrial and Commercial Consumers

  • Action Item: Update internal procurement policies to ensure compliance with the revised energy efficiency standards when purchasing transformers. Evaluate the long-term cost benefits of higher-rated energy-efficient transformers.

Bureau of Energy Efficiency (BEE)

  • Action Item: Develop and implement a monitoring and enforcement plan to ensure compliance with the revised standards. Conduct awareness campaigns to promote the adoption of energy-efficient transformers.
