Organization Overview
The U.S. General Services Administration (GSA) operates a pumping station at Federal Center Building 8 in Denver, Colorado, supporting essential federal infrastructure.
The station includes seven VFD-controlled pumps, with one pump operating at a time, making efficiency under partial load conditions especially important.
The Challenge
Despite limited active operation, the pumping station experienced severe inefficiencies:
- Power factor as low as 0.18
- 44 kVAr of reactive power on each VFD circuit
- Excessive no-load current draw
- Unnecessary energy consumption and demand costs
The result was wasted electrical energy even when pumps were idle.
The Solution
Accentz Inc. installed an MPTS unit to correct power quality at the load level. The project included:
- Pre-installation meetings and site inspection
- Installation and commissioning
- Measurement & Verification (M&V) using live monitoring
- Side-by-side comparison of pre- and post-MPTS performance
The Results
The results were immediate and independently verified:
Electrical & Energy Performance
- 82% reduction in no-load current (54 A → 9.72 A)
- 25.6% reduction in on-load current
- Reactive power reduced from 44 kVAr to 2 kVAr
- Power factor improved from 0.18 to 0.98
- 35.61 kW of estimated demand reduction
Financial Impact
- 314,613 kWh annual energy savings
- $31,461 in estimated annual cost savings
- ROI achieved in less than one year
These improvements were confirmed by the GSA Resource Efficiency Manager, validating the technology in a federal operating environment
Why This Matters
For infrastructure with intermittent load operation, power quality losses can dominate energy costs.
MPTS eliminated waste even when equipment was not actively producing work, transforming idle electrical loss into recovered capacity.
Ideal Applications
- Pumping stations
- Water & wastewater facilities
- VFD-driven systems
- Federal and municipal infrastructure
