The Philadelphia Eagles recently announced plans to power Lincoln Financial Field with a combination of onsite wind, solar and dual-fuel generated electricity, making it the world’s first major sports stadium to convert to self-generated renewable energy, according to the Eagles. The franchise has contracted with SolarBlue, a renewable energy and energy conservation company to install the system. The planned design includes approximately eighty 20-foot spiral-shaped wind turbines on the top rim of the stadium; 2,500 solar panels on the stadium's facade; a 7.6-megawatt (MW) onsite dual-fuel cogeneration plant; and a monitoring and switching technology to operate the system. The completion goal is September 2011.
SolarBlue will invest more than $30 million to build out the project, and will maintain and operate the stadium's power system for the next 20 years at a fixed percent annual price increase in electricity. The football franchise will save an estimated $60 million in energy costs. The partners also project that Lincoln Financial Field will provide 1.039 billion kilowatt hours of electricity, enabling an estimated four megawatts of excess energy off-peak to be sold back to the local electric grid. The energy to be generated by on-site renewable sources is comparable to the annual electricity usage of 26,000 homes. Solar Blue estimates that converting the stadium to renewable energy will eliminate CO2 emissions equivalent to that produced by the consumption of 500,000 barrels of oil. That equates to the removal of carbon emissions of 41,000 cars each year. See the SolarBlue press release .
