The Eagles are taking their gridiron off the grid.
The team said Thursday it will add wind turbines, solar panels and a cogeneration plant at Lincoln Financial Field over the next year, a combination that will make the stadium self-sufficient and let the Eagles sell some power back to the electric grid.
Eagles owner Jeffrey Lurie said the plan was part of the Eagles' commitment to be a socially responsible organization.
"Owning an NFL team, I think you have an opportunity to lead the way," Lurie said.
Under the plan, approximately 80 spiral-shaped wind turbines will be mounted on the stadium's roof and 2,500 solar panels attached to the stadium's facade. Together, they will contribute an estimated 30 percent to the total energy production.
An onsite "dual-fuel" cogeneration plant, a small power plant that captures its heat for increased efficiency powered by biodiesel and natural gas, will contribute the rest of the energy. The system is designed to produce at least 8.6 megawatts of power, enough to meet the stadium's peak energy use of around 7 megawatts.
