  Duke Energy Corp. on Tuesday said North Carolina's Duke University will purchase about 101 megawatts of solar capacity under the company's Green Source Advantage program. 


  Duke University is the first academic institution to take part in the program, the company said. 


  Duke University will work with Pine Gate Renewables to build the solar projects, which are being developed in partnership with Silver Pine Energy Holdings, Duke Energy said. The projects are expected to be online by 2022. 


  Under the Green Source Advantage program, customers and developers bear the additional costs associated with energy from the facility, Duke Energy said, adding other customers don't pay for any part of the project. 


  Duke University's participation in the program will help it reach its stated goal of becoming carbon neutral by 2024, Duke Energy said. 


  Duke Energy also said there is 600 MW of overall capacity available under the program, with about 30 MW still available to eligible customers. 


  Earlier this year, the city of Charlotte and Bank of America signed contracts to participate in the program.
