Lighting controls improve efficiency at Port of Savannah

* In January 2019, Phoenix acquired Bright Light Systems. The project below references the previous generation of Phoenix’s Highland Series and the LIT System.

End Customer: Port of Savannah
Location: Savannah, GA

Project Details

The Port of Savannah is the largest single container terminal in North America and the 4th busiest port in the United States. Ocean Terminal is the Port of Savannah’s dedicated breakbulk and Roll-on / Roll-off facility that covers over 200 acres and provides more than 1.4 million square feet of covered, versatile storage for its customers.

Problem
Ocean terminal has over 400 high pressure sodium lights for illuminating the container yard during operations. The lighting is controlled manually via circuit breakers or through use of a photoelectric controller. Many of these lights are left on during the day and inevitably burn out requiring replacement on poles that measure over 110 feet high. Illuminance levels are not meeting safety and security requirements for nighttime operations at the port.

Solution
In 2017, legacy HPS high mast poles were retrofitted using state-of-the-art High Mast fixtures (known today as Phoenix Highland Series) with wireless lighting controls (known today as Phoenix LIT System™). These fixtures consume only 580 watts and offer flexible optical packages for optimal light coverage. The crisp, brilliant white light offers improved color recognition for security cameras and better night-time visibility for port personnel. Integrated wireless controls achieves up to 30% in additional energy savings. Adjustable glare shields eliminate light pollution for the surrounding residential community. A 100,000 hour L80 lifetime reduces maintenance costs by $39,766 annually.

Results

• Projected annual kWh saved: 1,356,048 kWh
• Projected annual energy savings: $108,484
• Projected annual maintenance savings: $39,766
• Achieved 5 fc illuminance avg on the wharf
• Payback: 3.2 years
