Over the past decade, Montgomery County Public Schools (MCPS) has continued to develop solar power purchase agreements (PPAs) for on-site renewable energy generation. In 2008 and 2009, MCPS began hosting large-scale rooftop photovoltaic systems at eight schools, with 1.3 megawatts of installed capacity. In 2015, rooftop solar photovoltaic systems were installed in four schools with additional capacity of 1.7 megawatts. MCPS is developing additional solar PPA installations at five more schools, with an added capacity of 1.4 megawatts. 

As a result, MCPS is a leader among Maryland school districts in hosting net-metered solar power purchase agreements, with an estimated 4.4 megawatts of installed capacity by the end of 2018. The 17 school sites with photovoltaic systems are projected to produce an annual capacity charge cost avoidance of approximately $290,000. MCPS is committed to purchasing additional solar PPAs that provide positive financial incentives for the development of local solar PV arrays. MCPS is particularly interested in the potential of aggregate net metering using off-site solar PV systems.
