On June 22, 2021, Maine Governor Janet Mills signed legislation adopting an energy storage deployment target for the state. The bill sets a goal of 300 MW of installed energy storage capacity within Maine by the end of 2025 and 400 MW by the end of 2030. The State Energy Office is tasked with revising the energy storage goal every two years after 2030, and also directs the Office to conduct an energy storage market assessment study outlining the opportunities and challenges to reaching the goal by March 2022. Additionally, Maines’ Public Utilities Commission will study potential rate structure adjustments such as time-of-use rates to further encourage energy storage growth. The bill further expands the authorities of the Efficiency Maine Trust to include energy storage and the Trust is also directed to undertake a storage pilot program, which will deploy up to 15 MW of storage at critical care facilities, such a hospitals, health care facilities, fire departments, emergency  medical  service  departments,  police  departments,  public  safety  buildings, emergency shelters beginning in January 2022. Maine is the 9th state to adopt an energy storage target, joining California, Connecticut, Massachusetts, New Jersey, New York, Nevada, Oregon, and Virginia.
