Case Examples 37 The four microgrid case examples are used to demonstrate the economic and technical feasibility along with the processes involved in planning and development. They cover different building sectors that can all similarly benefit from the increased reliability and resiliency that comes with an advanced microgrid.

Case Examples 43 Intent of Operations The feasibility study for this microgrid project was commissioned by Amtrak with the support of Booz Allen Hamilton for the NYSERDA funding opportunity. Amtrak's primary consideration in the development of this microgrid was for the increase of reliability and resiliency of their power supply, not just in relation for outages caused by natural disasters but also because of frequent outages to their system in Long Island City caused by distribution grid reliability problems.
