The Maine International Cold Storage Facility project involves the design, construction, operations, maintenance and financing of a 107,000 square foot cold storage facility adjacent to theMarine Terminal (IMT) in Portland, Maine under a 50-year lease with the Maine Port Authority (the Project). MICSF is the largest rooftop solar PV array in Maine.

The Project will deliver critical infrastructure to support the domestic and international transportation and distribution of refrigerated products throughout northern New England and will create long-term environmental and economic benefits for Maine.

The Maine Department of Transportation (Maine DOT) has contributed over $65 million to expand the operational capacity for logistics, freight and shipping at the IMT and will provide funding for the Project which will play a key part in this ongoing expansion.

Why we invested

Amber invested in this project due to the innovative business model created for the MICSF with public funds securing riskier elements of the construction and ownership.

  • Significant sustainability benefits including CO2 reduction, reduction in trucking miles and onsite electrical generation
  • Demonstrable benefits for local and State economy
Sustainable Development Goals (SDGs)

2030 Agenda for Sustainable Development adopted by UN Member States in 2015

SDGs supported:


Maine currently has insufficient cold storage facilities to support food and pharmaceutical industries which are key drivers of Maine’s economy. Ongoing growth of the food industry in Maine, consumer trends and demands on all segments of the supply chain have necessitated the need for increased modern cold storage capacity.

  • The Project has strong local and state political support, including endorsement of the Governor's office because of the widespread long-term economic and environmental benefits of the Project to Maine 
  • The development team has engaged with stakeholder groups throughout the permitting, planning and preliminary design process and will continue stakeholder outreach through Project delivery
