    Waikoloa Solar + Storage

    solar panels and sunny skies PNG Waikoloa Solar + Storage Project

    Hawai'i’s 100% clean energy future – locally produced renewable energy

    In 2008, the State of Hawai’i established a goal to reduce the state’s reliance on imported fossil fuel and produce 100% of electricity from renewable energy sources by the year 2045. In 2018, the Hawaiian Electric Companies (HECO) issued the largest ever Request for Proposals (RFP) for renewable energy in the state’s history. Through that process, eight projects were selected including AES Clean Energy's Waikoloa Solar + Storage Project.

    $45.8 Millionjob creation and economic output


    AES is deeply committed to lifting communities during these challenging times and is working diligently to start construction as soon as possible. It is estimated that the Project construction would result in creation of 193 jobs and generate a total economic output of $45.8 million toward Hawai‘i's economy.

    $0.08 kWh

    low-cost renewable energy


    Under a Power Purchase Agreement (PPA) approved by the Public Utilities Commission (PUC), the Project would deliver power at $0.08/kWh – one of the lowest in the state for renewable energy, and less than the cost of fossil fuel power.*


    of the Island's energy needs


    Upon completion, the Project is anticipated to contribute approximately 7.1% of Hawai‘i Island’s energy needs.*


    barrels of oil avoided



    The Project is expected to result in total avoided fuel consumption of 511,086 barrels of oil over its 25-year span. *

    Important Updates 

    Plan and Permit Approvals -Received 

    In April, 2021, AES received Hawaii County plan approval and grading permits for the Waikoloa Solar + Storage Project.  

    This important milestone marks the start of Project construction. In the coming months, area community members may notice increased activity at the Project site. Throughout the construction process, we will utilize best practices to minimize impacts to the area community, especially traffic, noise and dust. If you have questions or concerns, please contact us at

    Collaboration and engagement

    AES Distributed Energy is deeply committed to becoming an active, invested member in the communities we serve.


    Community input

    Throughout the process, AES 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.



    AES 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 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 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 prepared renderings to simulate views of the project from various vantage points. View and download visual simulations below.


    Culture and archaeology

    AES 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).
