Power Factor Cost Reduction

Poor power factor costs the economy over $500 million a year in unnecessary customer costs

What is power factor?
It is a measure of how efficiently your electrical equipment uses power from the grid. It’s not a reflection on how old your equipment is, but it’s the type of equipment that matters.

How much does it cost
Some equipment can have power factors of less than 60%. This means that for every $10,000 of capacity charges you pay the grid, you only get to use $6,000 worth.

Does everyone pay this?
Different networks charge different tariffs, so the cost will vary across the country.  However, ALL network tariffs are increasing AND more and more business customers are being put onto expensive network tariffs.

What can I do about it?
Power factor correction is designed to make your equipment more efficient.  Instead of buying more capacity from the grid, the power storage devices in the PFc inject expensive peak power.

Understanding Power Factor

To understand power factor, visualize a horse pulling a railroad car down a railroad track. As the railroad ties are uneven, the horse must pull the car from the side of the track. The horse is pulling the railroad car at an angle to the direction of the car’s travel. The power required to move the car down the track is the working (real) power. The effort of the horse is the total (apparent) power.
Because of the angle of the horse’s pull, not all of the horse’s effort is used to move the car down the track. The car will not move sideways; therefore, the sideways pull of the horse is wasted effort or nonworking (reactive) power. The angle of the horse’s pull is related to power factor, which is defined as the ratio of real (working) power to apparent (total) power. If the horse is led closer to the center of the track, the angle of side pull decreases and the real power approaches the value of the apparent power. Therefore, the ratio of real power to apparent power (the power factor) approaches 1. As the power factor approaches 1, the reactive (nonworking) power approaches 0.

This scenario can be applied to power factor demonstrating that often only a percentage of the current provided by electrical utilities that is being paid for is being used.

PowerSave Analysis

Edge uses a sophisticated analytics process to recreate a virtual bill of a customer’s network demand charges ($/kVA). All site analysis uses 12 months of meter interval data to exactly match the customers’ demand charges and then evaluate the change in these demand charges with a PowerSave installed. All PowerSave units are sized to provide the ideal balance of economic performance and sufficient additional kVAr capacity to provide flexibility should site load increase. Find out how much you could save using the PowerSave calculator and book your analysis below.
