Air is only free until it’s compressed. Then it accounts for nearly 10 percent of electricity consumption and wastes as much as 20-30 percent of that energy through leaks and artificial demand caused by overpressurization. Further efficiency gains are possible by adding controls, upgrading equipment and system design improvements. PPL offers rebates of $0.06/kWh of energy saved by improving compressed air efficiency.

Rebates are available for:n Efficient air compressors

n Dryers

n Storage tanks

n Zero-loss drains

n Air nozzles

Savings are in the air

PPL Electric Utilities offers rebates toward solutions for compressed air waste

Decrease waste, increase savingsEarn rebates Reduce your payback time with custom rebates of $0.06/kWh saved annually, offsetting upgrade costs so the savings start sooner.

Lower your energy bills Upgrading your air compressor reduces air leaks and energy waste, so your monthly energy costs could go down.

Clean up the mess You would fix a leak in the hydraulic line if you saw one, right? Every drop creates mess and wastes you money. Air leaks might not make a mess you can see, but they certainly lose you money. Time to clean up.

Improve efficiency and productivity Inefficient air compressors need more frequent repairs. With efficient equipment, there is less downtime due to maintenance, so productivity rises.

Possible air waste scenariosn Look into getting a variable-speed drive (VSD) to trim

your compressed air usage. VSD compressors match air production with plant air demand. For non-baseload machines, this can add up to a lot of energy saved.

n Match your compressor’s size to the load required. Compressors can often sit idle and waste energy. Make sure your compressed air demand matches the compressed air supply.

n Identify all the ways you use compressed air and the respective flow requirements. There may be more cost-effective ways to get what you need without compressed air, requiring less energy, such as using low-pressure electric blowers for clean up instead of expensive compressed air.

Efficient Equipment $0.05/kWh

Custom Project $0.06/kWh

Ready to save? Our customers have saved 2.25 billion kWh so far, with 34,000 businesses making energy efficient upgrades—and we’re still counting. Will you be next?

Imagine the savingsDid you know that an air leak of just one-sixteenth of an inch in an otherwise efficient system could cost you $1,046 per year at $0.10/kWh? Imagine how many one-sixteenth of an inch leaks exist in your facility. The losses could really be adding up.

SIZE OF AIR LEAK COST OF ENERGY WASTE PER YEAR

1/16 inch $1,046

1/8 inch $4,190

1/4 inch $16,764

Costs calculated using electricity rate of $0.10 per kWh, assuming constant operation and an efficient compressor.
