Green Electrical Systems Upgrades

A Powerful Opportunity for Cost Savings in Commercial and Industrial Buildings


Energy Saving Power Distribution Systems

Energy-efficient power distribution systems provide commercial and industrial facility managers energy data that was previously unavailable.  These systems utilize sophisticated networks that integrate power handling control with advanced wireless or Ethernet/IP-based monitoring. Frost is a leading expert in the St. Louis region in helping you identify these unique energy efficient opportunities and implement the correct solution for you!

  • Buildings consume approximately 40% of all US energy usage- more than transportation
  • LEED products are producing 0-30% energy savings compared to industry standards

Frost offers many Green Choice services to help you convert to a more energy-efficient solutions including:

NEMA Premium Motors and VFD Motor Control

The single largest end-use of electric power is the industrial motor. Variable Frequency Drives (VFD) can vary the shaft speed to match the driven load. VFDs allow motors to speed up or slow down, appropriately meeting the energy demand or power requirements at any given time. In this way, a fan, pump or blower operates at optimum efficiency even at partial load conditions. VFDs also allow motors to 'soft start,' reducing power consumption and peak power demand, as well as mechanical stress on the motor and the equipment driven by the motor. VFDs are particularly effective at improving HVAC efficiency because they meet the changing system needs of pumps and fans. VSDs are used for elevators, wastewater and water pumps, boiler fans, cooling towers, cranes, and conveyors.

  • Industrial motors consume more than 60% of all industrial electricity. Motors consume this much because they often run at constant or full speed even when it isn't necessary
  • Motors alone consume 25% of all U.S. electricity consumption
  • Variable Frequency Drives (VFD) can reduce a motor's electrical current draw by 10% - 50%

Uninterruptible Power Systems (UPS)

  • Higher efficiency UPS's can result in 50% less power loss, while reducing overall building energy costs

Power & Energy Management Systems

  • Provides date to negotiate lower usage rates
  • Controls demand in order to avoid electrical rate penalties
  • Identifies potential power issues which prevents costly problems
  • Poor quality power reduces productivity, shortens equipment life and erodes profit

Integrated Panelboards & Switchboards

  • Systems can include a combination of breakers, bus, lighting control, sub-metering and energy monitoring equipment

NEMA TP-1 Transformers, Filters & Power Factor Correction Capacitors

  • Decreases energy usage and loss by supplying power on demand

Submetering & Monitoring Systems

Smart meters communicate engery use information bewtween utilities and consumers allowing users to access energy usage information in real time. Understanding how energy is being used helps utilities and consumers save energy and money. For instance, in areas with peak pricing (higher electricity rates during peak consumption periods), smart meters and thermostats are used to communicate higher rates to the consumer. The consumer then has the option to lower the air conditioning or turn off appliances during higher energy rate periods. If consumers respond by reducing their energy demands, utilities can avoid bringing higher-cost 'peaker plants' online to generate extra power.

Reduce- Voltage Starters

  • Solid state, reduce-voltage starters lower peak starting current as much as 50%

Power Factor Correction Capacitors

  • Capacitors increase the power factor available to run industrial equipment and lower plant electrical costs by increasing the contented load by as much as 30% without increasing the size of the transformers, conductors, and protective devices.

Plug Load Centers

Another way to increase energy efficiency is to put office equipment on switches that can be turned off at night to reduce plug loads (the electricity used by any device that gets plugged into an electrical outlet). Even when they are turned off, plugged-in devices use standby power (the electricity devices consume to keep internal clocks and display lights running even when turned off). For instance, cell phone chargers plugged into the wall still draw power even if they aren't charging a cell phone battery.

  • Plug loads account for 9% of residential energy use and 20% of commercial energy use in the U.S.

Reducing Industrial Facility Operating and Maintenance Cost

According to the US Department of Energy (DOE), the industrial and manufacturing sectors consume approximately 32% of all U.S. energy usage - more than transportation, residential or commercial segments.  As energy costs spiral upward, plant MRO managers are seeking cost-effective solutions that upgrade facilities and reduce energy costs. 

  • Industrial energy systems include: motors, pumps, combustion, steam, process heating, combines heat and power, and compressed air
  • DOE indicates energy systems account for roughly 80% of all industrial and manufacturing energy use
