RSP EONSTM CASE STUDY TENNESSEE VALLEY AUTHORITY (TVA)
TVA provides power for seven states using nuclear, hydro, and fossil fuel plants. In an effort to specifically reduce maintenance costs in their switchyard locations, TVA looked closely at their current installed lighting products which was a large contributor to their existing maintenance expenses. Initial plans were to replace existing products with either an LED or Induction lamp product. On paper, both were able to partially reduce maintenance costs due to their extended lamp life characteristics (50,000 hr & 100,000 hr).
However, both systems would result in a significant increase of up-front expenses due to the high initial cost of the products. The LED and Induction products also carry a significantly higher material cost at the time of relamp. LED products will typically have to be 100% replaced as the LED board usually cannot be swapped out like a traditional lamped product. Induction products can sometimes also require a complete fixture replacement, or a new lamp which can cost in upwards of 10X that of traditional HID lamps.
The RSP EONS product was the ideal product of choice for TVA, by providing an extended life solution at a fraction of the up-front costs associated with an Induction or LED product. The RSP EONS is able to provide an extended life solution by using (3) traditional 100W Ceramic Metal Halide Pulse Start Lamps, for a total rated life of 60,000 hours. The RSP EONS product was also chosen due to it’s durable construction and known product quality that will survive the test of time in a harsh working environment. By using traditional lamp sources, material costs at relamp are also significantly reduced.
Already installed at TVA’s Muscle Shoals and Chattanooga locations, the RSP EONS first scheduled group relamp will not be until 12 years, 4 months after original installation or 9.29.2020 (based on 10 hours per day, 7 days a week usage).
