The Provincial Energy Goals…
BC Provincial Energy Commitments:gy
–50% of BC Hydro’s incremental resource % yneeds met by conservation by 2020
–BC Government carbon neutral by 2010
–BC will be electricity self-sufficient by 2016
12/19/2008
3
The Municipal Challenges…
–Local government’s spend significant amounts of money on excess lighting
–BC municipalities have committed to lowering greenhouse gases
–Power costs are rising faster than inflation.

Adaptive Lighting – Street Lighting Opportunities
Opportunity Advantage
1 Reduce Lumen Output of Lamps to • Energy Savings 1 p p
Maintained Levelsgy g
• Obtrusive Light Reduction
S f S2 Dim Over-Lighted Neighborhoods
• Potential Significant Energy Savings• Obtrusive Light Reduction
3 Match Lumen Output to Variable IESNA Pedestrian Conflict Levels
• Significant Energy Savings• Obtrusive Light Reduction

22
Opportunity - Dim to maintain design level
Light reduced to Maintained Levels for life of lamp - up to 26% savings
12/19/2008

Opportunity – Reduce Lighting in Over-Lighted Areas
Set spacing results in over-lighted roadway

Opportunity - Match Lumen Outputto Variable IESNA Pedestrian Conflict Levels
Potential Savings – 30% to 50%

IESNA Roadway ClassificationsHigh – Medium - Low
• The IESNA classifies by pedestrian activity:
• High – 100 or more pedestrians per hour – within a city block (200m)
• Medium – 11 to 99 pedestrians
• Low – 10 or fewer pedestrians

Adapt Lighting to the Requirements
• Unless there is “High”activity throughout the nightactivity throughout the night,
• the lower levels allow for safety and safe movement yof vehicles and pedestrians.
• The potential energy savings up to 50%

Prince George Pilot Project
15th Ave Prince George, BC
Project Plan:To retrofit 171 Luminaires with Adaptive Lighting Control
2.5 km main arterial with commercial and residential roadway. Transit line operational until 8 p m with varying pedestrian conflict levelsTransit line operational until 8 p.m. with varying pedestrian conflict levels.

Energy Savings Prince George Pilot
67 Luminaires were converted16 luminaires were dusk to dawn controlled only
4 luminaires were dimmed to 50% - 11pm to 6am47 luminaires were dimmed to 70% 11pm to 6 am47 luminaires were dimmed to 70% - 11pm to 6 am
Power consumption at 100% light = 312 WP ti t 70% li ht 232 WPower consumption at 70% light = 232 WPower consumption at 50% light = 187 W

The BC Picture
Why BC Hydro is consideringWhy BC Hydro is considering Adaptive Roadway Lighting
There are 300,000 street lights in BC. Estimated power consumed in a year would be
i t l 360 illi kWhapproximately 360 million kWh. Just imagine 20% reduction in off peak hours.
That’s 72 million kWh hours per year
