The Commonwealth Utilities Corporation (CUC) received a $2,497,500 Project Grant awarded October 20, 2025, from the U.S. Department of the Interior's Office of Insular Affairs (OIA) under the Economic, Social, and Political Development of the Territories program (CFDA 15.875). The grant funds the procurement and installation of a new 2.5-megawatt fuel-efficient diesel generator on the island of Rota in the Northern Mariana Islands to replace an obsolete 2.5-megawatt Mitsui generator that has reached the end of its serviceable life. The new generator, rated at 900 RPM, 60 Hz, and 4160V, is designed to deliver reliable power while reducing operational costs and minimizing service downtime for the island's residents and businesses.

Project activities include purchasing a commercially proven, low-emissions 2.5 MW diesel generator with warranty backing; preparing the site and integrating the unit with existing plant infrastructure; shipping and installing the generator with certified contractor support; and commissioning the equipment with operator training to ensure optimal long-term operation. The project period extends through September 30, 2030, and supports OIA's mission to enhance energy resilience and self-sufficiency in U.S. insular areas by replacing aging, unreliable equipment with modern infrastructure that improves reliability, reduces outages, and safeguards essential services.

The commonwealth utilities corporation (CUC) seeks funding from the U.S. Department of the interior's office of insular affairs (OIA) through the energizing insular communities (EIC) program to procure and install a fuel-efficient 2.5-megawatt (MW) diesel generator on the island of rota. This project will replace the outdated 2.SMW mitsui generator, which has reached the end of its service life, making IT costly to maintain and increasingly difficult to repair due to obsolescence. The failure of this old unit is expected anytime soon. The new generator, rated at 900 RPM, 60HZ, and 4160V, is designed to deliver reliable power and enhance energy efficiency, reducing operational costs and minimizing downtime. By replacing the mitsui generator, CUC will improve service reliability, lower maintenance expenses, and reduce energy costs for the island's residents and businesses. This initiative supports OIA's mission to enhance energy resilience and self-sufficiency in U.S. Insular areas, contributing to a more sustainable and reliable power system for rota's community. Replace aging, unreliable units with a modern, fuel-efficient generator to improve reliability, reduce outages, and safeguard essential services. Activities: 1. Purchase a high-efficiency, low-emissions 2.5 MW diesel generator (commercially proven, warranty-backed). 2. Prepare site and integrate with existing plant infrastructure. 3. Ship to rota and install with certified contractor support. 4. Commission and train CUC operators for optimal long-tenn operation. The commonwealth utilities corporation (CUC) aims to acquire a new, fuel-efficient 2.5MW diesel generator to replace the outdated and inefficient mitsui generator. This replacement is crucial to improve operational efficiency by reducing fuel consumption and lowering overall operational costs. The current generator is beyond its service life, with maintenance becoming increasingly expensive and complex due to the unavailability of spare parts, making IT difficult to sustain reliable service. The new generator will enhance system reliability, ensuring more consistent power delivery and reducing downtime. IT will! Also align with cnmi's strategic energy plan by promoting cleaner, fuel-efficient technology, contributing to long-term sustainability, and reducing carbon emissions. By selecting a modern generator, CUC will ensure easier access to spare parts and technical support, addressing the ongoing challenges with the obsolete mitsui unit. The installation of the new 2.5MW fuel-efficient diesel generator will yield substantial benefits for the commonwealth utilities corporation (CUC) and the rota community. Within the first operational year, CUC expects a reduction in power outages by over 50%, enhancing service reliability for the island's residents, medical facilities, schools, airport, and businesses. The fuel savings will be significant, with an anticipated annual reduction ofsi,361,000 in fuel costs based on a price of $2.9931 per gallon. This cost-saving measure will directly benefit cnmi customers, as lower operational and maintenance costs translate into reduced energy prices. The new generator will replace the outdated mitsui unit, improving both cost-effectiveness and reliability. This upgrade will not only provide a more stable power supply- but also support cnml's long-term energy sustainability goals outlined in the energy action plan, ensuring better alignment with future energy needs. As CUC continues to grow and modernize its power infrastructure, the new generator will increase the utility's ability to manage future energy demands, ensuring continued energy security for the community and promoting a sustainable energy future for rota. The entire rota community, including public safety agencies, healthcare providers, schools, and the tourism economy.
