Energy Acquisitions in Hawaii

Resource Innovations (RI), a San Francisco–based utility software and consulting platform, has acquired Honolulu-based Shifted Energy to integrate its Grid Maestro DERMS technology into RI’s demand-side management (DSM) and grid-edge offerings. The deal expands RI’s capability to deliver end-to-end virtual power plant and flexible load management solutions at scale, with a focus on equitable access for renters and underserved communities.

A newly formed partnership between First Reserve and funds managed by affiliates of Fortress Investment Group has acquired a majority stake in Island Energy Services (IES) from One Rock Capital Partners, with One Rock remaining as a minority investor. IES is a Hawaii-based integrated fuel import, storage, pipeline and distribution operator that also runs a 50-location Texaco-branded retail network; the transaction closed in mid-2025 and terms were not disclosed.
