Inland Power is Transitioning to LEDs to Cut Costs, Improve Service
About two years ago, Pat Osborn, GIS and Facilities Coordinator for Inland Power of Spokane, Washington, began looking into the benefits that transitioning its 4,000 rural area lights to LED technology would bring to his co-op and its members. It is widely understood that LEDs consume about 1/3 the energy of high pressure sodium (HPS) lights, and they can function over five times longer without losing brightness. Plus, LED bulbs provide a more pleasant white glow in comparison to the harsh yellow light of HPS bulbs. The decision was made to move forward with converting the co-op’s HPS ﬂeet to LEDs.
“The money we save in energy is important, but the money we save by not changing lightbulbs or photocontrols as often is even more significant,” said Pat Osborn. “We figure that we’ve been sending a lineman out to service each HPS area light about every five years and that has been a significant source of expense for our co-op. Inland Power’s service territory is large, so some of our bucket trucks need to travel 100 miles to change lightbulbs.” Interested in evaluating different LED-based alternatives to HPS, Osborn invited Inland Power’s lighting distributor, General Pacific, Inc. of Fairview,
Oregon to demonstrate an AreaMax outdoor LED area light fixture manufactured by Evluma of Renton, Washington. Subsequently, Inland Power installed a dozen AreaMax lights at the homes of board members, co-op managers and others as a test. “We installed both 40 and 70 Watt versions to replace 200W HPS fixtures,” said Pat Osborn. “As nice as the 40Watt was for some uses, most people wanted more light, so we made the decision to standardize on the 70Watt versions.”
“In the end, the selection of Evluma was based on multiple factors,” said Pat Osborn. “Bottom line, we were looking for a lighting company that was focused on solving the problems of rural co-ops, such as the high cost of sending skilled linemen long distances just to replace bulbs and photocontrols.” “We decided that the most economical way to change out the fixtures is to hang a new LED light when we get called in to service the old HPS light,” said Pat Osborn. “So we budgeted for a certain amount of change-outs per year – about 300 lights.”
The economics of the changeover is made even more attractive when the Bonneville Power Administration (BPA), Inland’s electricity supplier, agreed to give them money back as part of the BPA’s program to reward steps taken in their region to conserve energy. “We figure the first time we don’t roll a truck for repairs is when the light will pay for itself,” said Pat Osborn.
Evluma’s AreaMax has special features to reduce co-op maintenance costs that other LED area lights don’t have. One of these is Photocontrol Failsafe™ operation. The AreaMax contains a special control module that calibrates and then tracks the local day/night cycle, such that should the photocontrol fail (which can happen every five years or sooner in normal operation), the AreaMax continues to turn on and off as though the photocontrol were functioning. There’s no need for the co-op to change out the photocontrol with a new one. “We like the failsafe feature because it ensures that we don’t need to go out to the site to replace anything for the full lifetime of the fixture, which is warranted by Evluma to be service-free for at least ten years,” said Pat Osborn.
AreaMax has other features that appeal to linemen as well. “The product’s lightweight and sleek design make it a lot easier for our linemen to hang compared to the old HPS lights,” said Pat. Another lineman-friendly AreaMax feature is Bluetooth wireless control, whereby lineman can turn the lights on or off and vary the brightness using a Bluetooth-enabled notebook PC or tablet. Linemen can use this feature to test the operation of the lights during the day, and the co-op’s meter-readers can use it to enable or disable the lights easily when the homes change ownership.
Inland Power will have converted about 800 HPS area lights to the Evluma AreaMax by the end of this year.
