Ameresco, Inc. announced its award from Hawaiian Electric Company for the proposed 'Ukiu Energy 40-megawatt (MW) renewable energy site in Maui. This innovative facility will add critical grid reliability to the island and move Hawaii closer to its clean energy goals, including the state's commitment to achieving 100% renewable electricity and carbon neutrality by 2045. The proposed facility will include a biofuel-powered generator with six dual-fuel engines.

It will offer firm renewable energy and provide a highly flexible capacity resource. This facility will also maintain power quality, enhance grid reliability, and allow for the additional integration of intermittent renewable resources. Importantly, in the event of a power outage, it will have the ability to be brought online, in black start mode, to help repower the grid.

Additionally, the fast, flexible engines will enable the current fossil fuel generators to turn down their idling engines, supporting decarbonization efforts. Key outcomes include not only renewable energy provided 24/7 to the island, but also a reduction in Maui?s dependence on foreign sources of fuel. In support of the 'Ukiu Energy facility, Ameresco is steadfast in its commitment to identifying meaningful ways to benefit the local community.

This includes supporting community organizations, social service providers, and non-profit organizations focused on environmental and natural hazard mitigation, quality-of-life enhancements, homelessness, Science Technology Engineering and Math (STEM) education, and youth recreation. Ameresco looks forward to engaging with the community to identify and support programs that benefit the local region throughout the life of the facility. The facility is part of Hawaiian Electric Company?s latest phase of clean energy procurements aimed at reducing Hawaii?s dependence on imported oil for power generation.

After the 'Ukiu Energy contract is finalized, it will be submitted to the Public Utilities Commission (PUC) for review and approval. Once approved, it will be built, owned, and operated by Ameresco, and is designed to interconnect to the Maui electrical grid at the new Hawaiian Electric Waena substation. 'Ukiu Energy is Ameresco?s fourth award with Hawaiian Electric, building on the success of Kupono Solar, a 42MW solar and 42MW/168MWh battery storage facility, on Oahu expected to come online in Second Quarter 2024, Pu`uloa Energy, a 99MW firm renewable generation facility, on Oahu expected online in 2027, and Pu`uloa Solar, a 6MW solar and 6MW/30MWh battery storage facility, on Oahu expected online in 2026.

'Ukiu Energy, Pu`uloa Energy and Pu`uloa Solar remain subject to PUC approval.
