Understanding Load Control

Load control means managing the use of electricity during peak usage periods to help control the costs of purchased power.  It also means helping Commercial and Industrial members similarly manage their peak usage.  The peak demand for electricity usually occurs because of common usage patterns.
By spreading power usage over longer periods during the day, and/or reducing peak demand, VEC is able to purchase power at more competitive rates.  Lower purchased power cost often results in stable rates for the members and communities we serve.

How VEC Can Help

VEC works with its large users to identify the equipment and processes that drive the peak demand. VEC can supply real-time metering and web-based reporting to help users understand their load patterns. Armed with this data, large users are able to identify the specific pieces of equipment that are driving up their costs. Working though Efficiency Vermont members may also implement solutions such as; Variable Frequency Drives (VFD's), Demand Control Equipment, Fuel Switching, and even On-site Generation.

Peak Load and Cost

The highest peak demand during the peak hour determines the kilowatt hour (KW) rate at which a large commercial or industrial consumer buys power for the next twelve months. This is known as ratchet. Simply stated, you pay for power at the rate set by the highest peak demand each month regardless of the amount of power sold. Demand reductions during peak times, therefore, often carries over to off-season energy costs.
The important role of load management comes in when the amount of the peak demand can be reduced or the period in which energy is used is extended. Load management can be as simple as an awareness of and scheduling of critical loads during peak times.  It can be through investing in efficiency improvements and new electro-technologies.  Load management can also be automated through facility load monitoring equipment and energy management devices and software.
