We model the electrical power generation potential, calculate the associated avoided emissions and conduct an economic valuation of a scenario of large scale photovoltaic canopy implementation in metro Boston, Massachusetts on publicly managed parking real-estate operated by the Massachusetts Bay Transit Authority. The results of this work demonstrate that 102.4 MWh of electricity may be generated by such a program which is equal to nearly 0.013% of total electricity demand in the state. Annual CO 2 , NO and SO 2 emissions avoided in this scenario amounts to 53.7 tonnes of CO 2 , 46.5 kg of NO, and 107.1 kg of SO 2 . Despite the substantial amount of power production potential we find that such a scenario is not economically viable under current market conditions and using conventional financing mechanisms with a net present value of -1.4 Billion U.S. dollars.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
