Electrical Efficiency in Hawaii

Signed into law by Governor Ige in 2015, House Bill 623 establishes a goal of 100% energy efficiency in the state of Hawaii by 2045.

Investigate the Problem

- Mr. Sucuma Elliot- Electric Engineer, Hawaii Department of

Education- Retired Electrical Engineer, HECO

- Inspected School Infrastructure- Reviewed State Solar Pilot Project

3

What are the issues facing Aiea High School?

- Fading lights- High energy usage- Campus Security

Electrical Cost of Lighting in Parking Lots

Cost of HID Lightbulbs at McKinley- One per Month: $22.02- One per Year: $264.24- Four per Month: $88.08- Four per Year: $1056.96

Cost of LED Lightbulbs at McKinley- One per Month: $10.32- One per Year: $123.84

- Four per Month: $41.28- Four per Year: $495.36

New Plan

A plan for Aiea High School to install LED lightswill increase efficiency because LED lights require less maintenance, less electricity, and heighten security.

Why LED?

- Energy Efficiency and Renewable Energy Program

- Natural Solid State Lighting

Where Would They Go?

Red Dot: WP2LED Family

Purple Dot: WP3LED Family

What would this do for our school?

- Maintenance

- Efficiency

- Security (Night-time)

6

Maintenance

- Average Life of HID (High Pressure Sodium): 20‐25,000 Hours

- Estimated Life of Proposed Lights: 100,000 Hours

Efficiency

- Lumens- Want the most!- Lumens = Most Lighting

- Wattage

- Typically want a lower wattage

- Unit represents energy generated for light

7

Security

- HID decline in performance over time

- Potential Work Hazard- Night Events- Games- Parking Lot

Challenges – Way Ahead

• PUC Findings – Oct 2015 the landscape changed• Re‐Key Event occurred to re‐set priorities / strategy• New Priorities emphasized

• Micro‐Grids• 5 currently under development

• Financing options• Legislative options

• Finish the build out of the current NEMs• Apply the Honowai model to other schools• Line item the Micro Grids in the next budget request• Continue the Education part of this program ‐ Perry
