For almost 20 years, BPA has maintained a robust nonresidential lighting offering. BPA continues to invest in the lighting program as a critical component to achieving regional conservation targets.

BPA offerings provide ample opportunities for utilities and their customers to improve their energy efficiency, enjoy cost savings, and reap the non-energy benefits of upgraded lighting.

Lighting Calculators

BPA’s nonresidential lighting offering is captured in an easy-to-use, Microsoft Excel-based tool – the BPA Lighting Calculator. While the Lighting Calculator can be downloaded from the BPA website  here, please note that BPA’s customer utilities use their own branded versions of the BPA Lighting Calculator. Contact your local BPA customer utility to receive their customized version of the BPA lighting calculator. A simple zip code look-up tool to identify the local utility contact is available on the Trade Ally Network NW website here.
