Grenlec and our Government are piloting the use of energy-efficient LED street lighting in select public street locations throughout Grenada to evaluate the economic, safety and environmental benefits of this advanced lighting technology.
LED street lighting is proven to be more energy-efficient, durable, longer-lasting and brighter than conventional street lighting, which could provide significant savings of up to 50% in energy and maintenance costs, as well as increased public security. In addition, LED lighting cuts down on greenhouse gas emissions, contributing to a healthier environment and a “greener” Grenada.
Since not all LED lighting is the same and performance varies by manufacturer and product type, Grenlec will be comparing three LED manufacturer lighting products against the existing high-pressure sodium (HPS) lighting at a variety of locations.
Pilot Project Locations:
| Location | LED Manufacturer Lights | |||
| Total | A | B | C | |
| Maurice Bishop High Way – Airport to SSU | 12 | 4 | 4 | 4 |
| Maurice Bishop Highway – Sugar Mill Roundabout to True Blue Roundabout | 6 | 2 | 2 | 2 |
| True Blue – Dusty H/way intersection to Yacht road junction Quinn Co. | 6 | 2 | 2 | 2 |
| Port High Way, Tanteen – Yacht Club to Burns Point | 3 | 1 | 1 | 1 |
| Carmerhogne Park – main entrance to Grand Anse Beach | 3 | 1 | 1 | 1 |
| Morne Rouge – Wall Street Roundabout to Spice Inn | 6 | 2 | 2 | 2 |
| Victoria Street, Grenville | 3 | 1 | 1 | 1 |
| Gouyave – Main street to Fish Market | 3 | 1 | 1 | 1 |
| Total number of LED Lights to be installed. | 42 | 14 | 14 | 14 |
Testing Process
Because of the variances in lumens (light output), color rendition, and light distribution of LED technology, it’s important to test the performance of the products on actual road surface conditions to measure the differences in light quality, color, brightness, light direction, and energy use.
Grenlec is also conducting a survey to gain customer observations and preferences between the three types of LED street lighting being tested.
The LED Street Light Pilot Project will run through 26 May 2015, providing time to collect technical performance data and customer survey information for assessing the LED street light options. Further evaluations and results of this pilot will determine the economic feasibility and schedule for future LED street light installations in Grenada.
LED Lighting Facts:
- LED stands for Light Emitting Diode. LEDs are semiconductor devices that produce visible light when an electrical current passes through them.
- Lasts up to 2.5 times longer — results in fewer street light outages and saves on replacement lamp costs
- Uses up to 50% less energy — saves on electricity costs
- More durable than conventional lighting — saves on maintenance costs
- Produces consistent, more even “directional” light — resulting in fewer “dark spots” and more direct light on specific areas
- Reduces light pollution caused by excessive outdoor light that wastes energy and disrupts the environment
- Provides better color rendering for brighter light and increased visibility to help improve public safety.
