Hannah Solar Government Services was contracted to build a solar energy microgrid system on Wake Island which is a possession of the United States located about 2300 miles west of Hawaii in the Pacific Ocean. Wake Island is a 2.7 square mile island which is a military base and is home to the largest airfield in the Pacific islands. Wake also hosts missile launching and tracking facilities of the United States Missile Defense Agency.
The solar energy microgrid system installed included a 740 kW solar array, a 571 kWh battery system and a microgrid controller system that manages the new solar array, the new battery system and existing diesel generators. This project was extremely cost effective for the US Government as diesel fuel to run the power generation on the island must be shipped from Hawaii to Wake twice a year over a distance of 2300 miles by ocean-going barge.
The logistics for construction of the project were exceptionally challenging due to the limited services available for working at Wake Island. The only way to get personnel to Wake were using a US Air Force aircraft from Hawaii that only runs once every other week. The only way to get the construction equipment, vehicles and construction materials to Wake was to contract an ocean-going barge from Hawaii to Wake. Everything had to be loaded in sealed, water tight shipping containers that were shipped from many locations around the world to Hawaii and timed to arrive within a short window of time to load onto the ocean-going barge. Additionally, a return barge had to be scheduled after construction was complete to remove the shipping containers with all equipment, excess materials and trash from Wake Island.
This presentation will provide an overview of the various types of microgrid systems relevant to the US military, why they are beneficial and discuss the complex logistics of implementing the Wake Island microgrid system.
