Lighting Survey Form (LSF)
Frontier Energy maintains the lighting savings calculator (technically known as the "Lighting Survey Form" or "LSF") used by many of the major Texas utilities. This calculator is updated on an annual basis to reflect current deemed savings methodologies as specified in the Texas Technical Reference Manual (TRM). The LSF is updated periodically with the latest approved lighting technologies (per Utility request) and later incorporated into the annual LSF update at the beginning of each new program year.
The LSF includes changes to lighting rules and requirements petitioned by the electric utilities of Texas and approved by the Public Utility Commission of Texas (PUCT).
