Project timeline

Collaboration and engagement
AES Hawaiʻi is deeply committed to becoming an active, invested member in the communities we serve.
Community input
Throughout the process, AES Hawaiʻi has and will continue to engage and listen carefully to community feedback on the Project. Specific issues identified by the community thus far are actively being addressed and we continue to seek input to ensure we are responsibly examining concerns.
Traffic
AES Hawaiʻi is committed to minimizing our impacts on Hawai‘i Island commuters.
- Construction Traffic Management Plan – During the 12-month construction phase, a traffic management plan is being implemented to minimize traffic impacts and to ensure the safety of all commuters.
- Where possible, delivery hours will be coordinated during off-peak hours (from 8 AM - 2 PM.)
- Parking and equipment laydown – Parking and equipment laydown will be located within the Project site.
- Minimal Operational Vehicles and Traffic – upon completion, only 1-2 vehicles per day will be required to operate and maintain the Project.
Fire and safety
Brushfires are a significant community concern and AES Hawaiʻi takes this issue very seriously.
- Fire Suppression – Each battery storage container is equipped with a fire suppression system that will minimize the risk of fire from Project components.
- Firebreaks – A non-vegetated firebreak will encircle the Project area as well as each battery storage area to further reduce fire risk.
- Vegetation Management – AES Hawaiʻi will actively maintain the vegetation on-site to minimize the risk of brushfires spreading through the property.
Unexploded ordinance (UXO)
- Safety is AES' number one priority. The Project area is within the Former Waikoloa Maneuver Area.
- Site-Specific Safety Plan has been developed prior to construction activities in accordance with the State of Hawai‘i Areawide Environmental Hazard Management Plan.
Visual impacts
Community members have raised visual impacts as an important consideration.
- Sensitive Siting –As much as possible, the Project has been designed and laid out to reduce visual impacts, especially from neighboring communities.
- Visual Simulations and View Planes –To better understand the visual impacts, AES Hawaiʻi prepared renderings to simulate views of the project from various vantage points. View and download visual simulations below.
Culture and archaeology
AES Hawaiʻi recognizes we have a responsibility to respectfully address archaeological and cultural resources early in the process. With this understanding, we started the Project by conducting a Cultural Assessment and an Archaeological Inventory Survey (AIS).
Contact us
We appreciate your interest and participation in Hawai'i’s renewable energy future. We look forward to hearing your ideas, thoughts and comments.
