Why did FortisAlberta change its lighting standards?

In response to customer requests and to improve the energy efficiency of our infrastructure, effective Jan. 1, 2016, FortisAlberta changed its standard for streetlights to Light Emitting Diode (LED) technology for all new construction and developed a conversion option for customers who wish to convert their existing streetlights from HPS (High Pressure Sodium) to LED fixtures.
