Premier Lighting Case Study: LED Optimization Project
Customer Profile:
Enterprise Rent-A-Car was founded in 1957, named after the WWII aircraft carrier the US Enterprise, on which the company founder served during the war. Today Enterprise has operations in over 30 countries with over 7,20 locations. In Minnesota, Premier Lighting has been proud to assist with lighting at several Enterprise locations.
Goal:
Enterprise Truck Rental in Eagan had 54 - 400W metal halide fixtures illuminating the facility interior and the truck wash area. Light levels averaged around 27 footcandles and maintenance of the fixtures, changing lamps and ballasts, was becoming a chore. Enterprise reached out to Premier to examine what new LED fixtures could do for the operation in terms of energy and maintenance savings and improved light levels so technicians could better observe vehicles for damage or mechanical issues.
Solution:
Premier reviewed the current lighting situation and created different lighting layouts. Premier proposed new LED fixtures reducing the fixture amount from 54 fixtures to 33 LED fixtures. This optimization resulted in achieving the goals stated and Premier coordinated the entire project from ordering, installation, and rebate paperwork.

Understanding Your Utility Bill
If you're looking to save costs on energy, first make sure you have a good understanding of how you are being billed by your utility company. Understanding the intricacies of your utility bill will allow you to fine-tune your energy-saving efforts.
First, lets consider kWh vs. kW. kW (kilowatts) is the rate at which you are using energy at any given time, while kWh (kilowatt hours) is the total energy used over a period of time (eg. a month). An easy way to look at it is to compare it to driving. In this case, kW would be miles per hour and kWh is the total miles driven over time. kWh is easy to nail down. Simply put, it's the total energy consumed over that billing period. kW meanwhile is your energy demand rate that is averaged out in fifteen minute increments. The kW rate shown on your bill reflects the highest 15 minute average in that billing cycle. So if you have 50 kW early in the month but then do not go higher than 30 the rest of the month, the kW on your bill will still be 50 (of course, your kWh will be much better off having gone from 50 kW for a period down to 30 kW).
The other thing to be clear on is, not all accounts are the same. With very low-use accounts, kW may not even be billed (just total kWh). Naturally, bigger accounts become more complicated as different variables come into play. On peak / Off peak hours is a common one, with overnight (off peak) hours being billed at a lower rate. Large accounts also have an option for discounted kW rates based on controllable loads. This means that a large account can qualify for a discounted kW rate if they are able to significantly lower their energy usage for a period of time (by 50 kW or more to be eligible). This can be done by turning off equipment or by operating a portion of the facility on a generator. There are different Tiers for contract levels as well. Accounts on 10 year contracts are due to receive higher discounts than those on a 5 year contract, for example.
