Renewable and Onsite Generation - FY18 Snapshot
In Fiscal Year 2018, state government consumed nearly 1.4 billion kWh of electricity. Of this, 6% was generated by onsite renewable power and 13% came from onsite Combined Heat and Power generation. This generation is equivalent to the kWh needed to supply electric power to over 35,000 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 from onsite electricity generation.
Annual Grid Electricity Use vs. Renewable and Onsite Generation
In Fiscal Year 2018, 19% 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 October 2020, there are 28.6 MW of installed solar capacity at state sites, up from less than 150 kW a decade ago. These installations generate an estimated 32.5 million kWh of solar power a year, equivalent to the annual electricity use of 4,285 Massachusetts homes.
