Looking to lower the town’s energy costs and provide valuable protection against future utility price increases, Glastonbury decided to evaluate options for solar systems.
Glastonbury partnered with SolarCity to assess the town’s energy consumption and overall energy needs, and strategically place solar arrays in locations most beneficial from both a savings and safety perspective. The town started with three projects at their town hall, high school and maintenance yard. It later expanded its portfolio to include installations at two elementary schools and the bus yard, as well as at a parks and recreation facility.
Together, the systems total 1 megawatt of solar generation capacity, enough to produce 1.27 million kilowatt hours of electricity for the town each year. In total, the solar panels are expected to avoid approximately 27 million pounds of CO2 emissions, and prevent the waste of 1.6 million gallons of water that would otherwise be used to generate electricity from other sources over the lifetime of the project.
Through a SolarCity Power Purchase Agreement (PPA), Glastonbury avoided paying any money upfront for their solar systems and instead buys the power the panels create at a discount to what they pay for utility power. The agreement is expected to save Glastonbury taxpayers more than $100,000 per year—savings that will run in the millions over the course of the 20-year agreement.
