Press Releases

(Washington, DC) – U.S. Representative Ed Case (D-HI-01) today announced that a $40 million grant funded by the landmark 2021 Bipartisan Infrastructure Law (BIL) will develop a back-up power source for O‘ahu’s electric grid, providing resiliency to both military and civilian communities in the event of disruptions from various sources. 

The federal grant award will fund the Pu‘uloa Microgrid and Backbone Project, a partnership between the U.S. Navy, Hawaiian Electric and Ameresco, Inc.

“I strongly advocated for this project with the U.S. Department of Energy when the partnership applied for funding under the Department’s Grid Resilience and Innovation Partnerships (GRIP) program,” said Case.  

“Joint Base Pearl Harbor-Hickam (JBPHH) plays a critical role in promoting national security throughout the Pacific theater. Especially given its importance, the Department of the Navy has identified energy resilience gaps that could significantly impact JBPHH’s ability to respond to and recover from grid outages. Further, new state and federal policy directives have required the Department of the Navy to improve resilience and reduce carbon emissions from the installation. 

“As the U.S. Congressman in whose district JBPHH is located and a member of the House Appropriations Committee Subcommittee on Defense, I have focused on the installation’s grid challenges and the potential for disruption of service to our civilian communities as well, and on assuring available funding to address these issues. This GRIP funding is critical to enabling this project to succeed.”

"We are thrilled to be chosen for the Department of Energy’s GRIP program," said Nicole Bulgarino, Executive Vice President at Ameresco. "Partnering with the U.S. Navy and Hawaiian Electric Company on the groundbreaking Pu`uloa Microgrid project will not only enhance energy resilience and reliability for Joint Base Pearl Harbor-Hickam, but also provide significant benefits to the broader O‘ahu community. This project exemplifies our commitment to innovation, sustainability, and community engagement."

According to the project description, the Pu`uloa Microgrid will detect the loss of power during grid outages, disconnect from the broader grid and direct power from Pu`uloa Energy to support JBPHH’s national security needs while maintaining civilian community service. During a full island outage, the system will provide black start capabilities. The project will also improve power quality to JBPHH and the local grid through ancillary services such as frequency response and voltage support. 

Pu`uloa Microgrid is designed to strengthen the grid and improve resilience by increasing or establishing interconnections between Hawaiian Electric substations at JBPHH with new 46 kV transmission infrastructure that will be integrated into the microgrid control system and utilize state of the art smart grid technologies.

“Since 2021 I have been working hard to ensure that my government and community partners throughout Hawai‘i are aware of project and funding availability from both the $1.2 trillion BIL, as well as from the $500 billion Inflation Reduction Act (which Congress passed in August 2022). Together these two landmark measures are addressing our country’s most pressing infrastructure needs including those arising from climate change,” said Case.
