    The Role of Microgrids and Community Choice Aggregation in Building a Sustainable and Resilient Energy System

    Energy plays a role in every facet of our lives - from food production to clothing and shelter, to the water we drink and the air we breathe and by great extent our ability to do the work we enjoy. With that being said, the energy sector, globally, is plagued with many challenges. For example, the electric grid and most of the energy infrastructure in the US was constructed in the 1950s and 1960s with a 50-year life expectancy1 which signifies the US is due for an overhauling of the system. This does not account for the fact that the energy system of the 1950s and 1960s was not engineered to meet today's energy demands and capability to withstand severe weather related events – in 2012, Super storm Sandy demonstrated our energy system vulnerability to severe weather. All of this suggests that the time is at hand for significant investment in maintaining, upgrading and rebuilding the electric energy infrastructure. Recently conducted research suggests that the replacement value of the U.S. electric grid is $4.8 trillion2.

    This discussion will focus on the use of Microgrids and Community Choice Aggregation (CCA) in addressing the impending energy crisis and assess the social, economic and environmental benefits of employing such an approach to tackling the current energy challenge. Beyond the US, microgrids and CCA offer the opportunity for developing nations to leapfrog the centralized energy infrastructure and provide a more sustainable
    and secure energy system for the 21st century.
