Renewable and Onsite Generation - FY17 Snapshot
In Fiscal Year 2017, state government consumed roughly 1.4 billion kWh of electricity. Of this, 5% was generated by onsite renewable power and 15% came from on onsite generation from clean CHP. This generation is equivalent to the kWh needed to supply electric power to 36,011 Massachusetts homes. Additional renewable energy credits accounted for less than 1 percent of kWh generation. The dotted red line represents the Executive Order 484 Target for Fiscal Year 2020 of 30 percent of total consumption.
Annual Grid Electricity Use vs. Renewable and Onsite Generation
In Fiscal Year 2017, 20% of state government’s electricity consumption came from on-site clean generation, an increase from 7% in Fiscal Year 2002. Renewable and on-site generation includes anaerobic digestion, hydro power, clean combined heat and power (CHP), solar photovoltaic, and wind power.
Annual Installed Solar PV Capacity
As of December 2018, there are 24.1 MW of installed solar capacity at state sites, up from less than 150 kW a decade ago. These installations generate an estimated 27 million kWh of solar power a year, equivalent to the annual electricity use of 3,670 Massachusetts homes.
