Project Description

CASE STUDY: Powersmiths Contributes 64% Reduction in Transformer Energy Losses to GSA Deep Energy Retrofit through ESCO Partnership

U.S. Federal – General Services Adminstration (GSA) Building

Missouri, 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 GSA 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 10 existing transformers
  • 70 Powersmiths E-Saver low-voltage dry-type transformers replaced the 70 inefficient existing transformers
  • Post-install energy savings verified by Powersmiths professional metering services in an ISO17025 Certified Lab

Energy Savings Overview:

  • Overall Annual Energy Savings: 627,214 kWh
  • Peak Energy Demand Savings: 68.2 kW
  • Annual GHG Emissions Reduction: 462.9 tons CO2
