Eastport's Future Powered by Tides: Exploring Renewable Energy Solutions for Local Resilience

The city of Eastport, Maine, with a population of 1,300, is exploring new solutions to improve its energy resilience. Located at the easternmost point of the continental United States, Eastport is well-placed to use the Atlantic Ocean for energy. Previously dependent on a diesel-fueled substation, the city has faced more power issues since the facility and local sardine factories closed. These problems have worsened due to more frequent and severe storms, underscoring the need for stable and sustainable energy sources.

In 2021, Eastport joined the Energy Transitions Initiative Partnership Project (ETIPP). This program helps communities like Eastport by using local knowledge and the expertise of national laboratories to boost energy resilience. Eastport's focus has been on creating resilient power systems and energy-efficient housing, and on encouraging local economic growth and community participation in planning.

With help from the Island Institute and researchers from the National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory, Eastport is assessing different microgrid options. These include a regional microgrid and a community-owned microgrid at a local elementary school. The aim is to incorporate renewable energy sources, especially tidal energy and solar arrays, into these microgrids. Maine's strong tidal currents offer a great opportunity for sustainable energy production, which could provide a steady and reliable power source for Eastport.

The benefits of using tidal power are significant. Tidal energy is predictable and consistent, providing a stable power supply that could help manage volatile energy prices and frequent outages. Eastport has seen a sharp increase in utility rates, nearly double the national average. By using tidal power in a microgrid system, Eastport could stabilize its energy supply and possibly lower costs for its residents.

The ETIPP initiative also focuses on educating the community about these new technologies and their benefits. This includes providing resources and demonstrating potential energy savings for homes and community projects. By improving energy efficiency and developing a microgrid, Eastport aims to build a more sustainable and resilient energy infrastructure. This not only addresses current challenges but also prepares the community for future growth and stability.
