Conversions DEV will now install LEDs at no charge when replacing non-functioning streetlights Upon request, DEV will replace with HPSV until inventory exhausted For functioning fixtures, conversion cost depends on classification $130 to replace basic fixture with LED $386 to replace premium fixture with LED 2018 change in DEV tax effect recovery factor (TERF) increases conversion cost by 15.34%

Conversion Savings Example: Arlington County Significantly reduced cost to convert an existing basic HPSV luminaire to LED: $1,364.45 per 2017 DEV estimate (average) $ 130.00 per 2018 agreement (flat rate) $ 150.00 per 2018 agreement + TERF Savings even with $386 cost to convert existing premium luminaires Including TERF brings cost to $445

LED Cost Savings Preliminary Estimates: Fairfax County Conversion can be an opportunity to upgrade outdoor lighting, but upgrades can impact savings Upgrades don’t affect conversion cost because the charge is based on the existing fixture # Fixtures kWh per Month Monthly Operating Cost + Riders, Fees & Fuel = Total Monthly Cost Today 56,421 3,185,895 $512,715 $135,617 $648,332 Possible Upgrade 1,541,455 $484,825 $67,505 $552,330

LED Cost Savings Preliminary Estimates: City of Fairfax Installing basic LED instead of premium HPSV will yield savings Estimated 10-year savings for 58 fixtures: Cost savings = $140,511 ($121,661 + $18,850) Energy savings = 313,200 kWh Emissions reduction = 257 MT CO2e New Installation: 58 Carlye Acorns (150 watt or equivalent) Type Class Monthly kWhs Monthly Cost Avg.
