roughly 80 % so that the amount eventually sent to the landfill is less than 20 % of the initial waste we generate overall . The electricity produced at the WtE facility flows back onto the grid for consumption by homes and businesses throughout the region . According to the U . S . Energy Information Association , 500 – 600 kWh of electricity can be generated by incinerating one ton of MSW in a WtE facility . 29
Reagan National
Based on the 5,300 tons of MSW that Reagan National sent to the WtE facility in 2019 , at 550 kWh per ton , we supported the generation of 2,915,000 kWh of electricity last year alone . Our waste provided the equivalent of 3.3 % of the electricity we used at Reagan National in 2019 . This is also equivalent to the production of a 2.15-MW solar farm 30 and enough electricity to power 266 homes . 31
Dulles International
Based on the 9,500 tons of MSW Dulles International sent to the WtE facility in 2019 , we supported the generation of 5,225,000 kWh of electricity last year alone . Our waste provided the equivalent of 2.4 % of the electricity we used at Dulles in 2019 . This is also the equivalent to the production of a 3.75-MW solar farm 32 and enough electricity to power 476 homes for an entire year . 33
Maintaining our Current Level of Electricity Consumption in a More Electrified Airport
The airport of the future will be one more reliant on electricity than ever before . As airports and society grapple with air quality issues and other environmental concerns , electrification is a potential solution to many of our current problems and is currently cost effective at utility-level scale . For example , converting airport bus fleets to electricity improves local air quality , reduces GHG emissions , and saves on both fuel and maintenance costs . Electrifying the wide array of airside GSE such as baggage loaders , food service trucks , and plane tugs improves the working conditions for our airside employees and partners by reducing fumes from gas and diesel-powered equipment as well as noise levels . eGSE can also save airlines money by reducing fuel and maintenance costs . Furthermore , as more airport customers and employees travel to and from the airport in EVs , the need for the Authority to offer more EV charging stations will continue to grow . Lastly , we have seen and anticipate continuing to see everincreasing plug-load usage in our terminals as more and more customers are utilizing our electric infrastructure to charge devices . This wholesale migration to a more electrified airport has tremendous benefits along with challenges as we need to ensure our electrical infrastructure remains robust enough over time to handle all of this expected incremental electrical load .
One of the ways we are preparing for this electrified future is by working with our partner , NREL , to analyze and model the impact of electrification over time . Knowing in advance the required electrical upgrades required to support an all-electric bus fleet , electric PTVs , increased plug loads , additional EV charging stations , and a ground service equipment fleet that is increasingly more electrified over time , for example , creates the opportunity for us to plan and budget for the required investments in our current infrastructure . Opportunities for fast charging , wireless charging , and spot charging of these vehicles throughout the day to complement overnight charging is also something we are focused on .
