Project Description

CASE STUDY: Powersmiths Transformers Contribute to 90% Reduction in Transformer Energy Losses for U.S. Department of Defense through ESCO Partnership

U.S. Federal – Department of Defense (DoD) Building

South Carolina, USA

Project Drivers:

  • Executive Order 13423/EISA: Reduce energy intensity by 30% by 2015
  • Executive Order 13423: Reduce GHG emissions by 28% by 2020
  • No capital investment by DoD with verified savings
  • Work completed as part of an Energy Savings Performance Contract

Project Summary:

Transformer Retrofit & Energy Savings Verification

  • Baseline measurements of energy losses from 12 existing transformers
  • 12 Powersmiths E-Saver low-voltage dry-type transformers replaced the 12 inefficient existing transformers
  • Post-install energy savings verified by Powersmiths professional metering services in an ISO17025 Certified Lab

Energy Savings Overview:

  • The average baseline energy losses were reduced by 90%
  • Lifecycle Energy Savings: 6,720,960 kWh
  • Overall GHG Emissions Reduction by 2020: 1157.1 tons CO2
