Zero Demand Systems

In certain parts of the country, (Florida in particular) Power Companies without excess generation capability will offer their Customers the option of a Program generally called "Zero Demand". This program provides incentives to high demand customers willing to shed their load during Peak usage periods. The savings can be substantial.

This allows the Customer flexibility to decide the Electrical usage required during this times. A detailed analysis will determine your overall costs.

Key Benefits

Lower Power Costs.

Automatic Plant backup in case of Power Failure.

Critical loads can be served. At times there are processes under way that would be financially detrimental to the operation if power were lost. (Example: Certification of Produce shipped to another state that has to be kept at a constant temperature for a defined period.)

Analysis

We can give you a complete Analysis of your Plant Electrical usage, Expected savings on your Power Bill and Design and price a system to meet your needs.

Plant Size is Unlimited

 

Shown is a 4,200 Ampere, 277/480 Volt Electrical Service consisting of (4) 800 Ampere Mains and (2) 600 Ampere Mains feeding a large Lime and Avocado processing plant in the South Florida Area. This Service is fed on the Power Company side by a 1500 KVA Pad Mount Transformer.

 

Automatic Switching

 

In this case, all of the loads are transferred to the Generator using Lakeshore Automatic Transfer Switches. These are shown across the right side and back walls. Other brands are available.

 

Operation and Cost Recovery

 

When a signal is received via phone line from the Power Company to the interface, the Generator starts and the Transfer is initiated. Generator is equipped with crankcase heaters to allow full load operation in the least amount of time. Customer expects full payout of this installation in less than 4 years. At the end of the Peak cycle, a signal to return to Main power is received, the loads transfer and the generator runs at no load for a predetermined time for cooling purposes before shutdown.
