Lightsource BP’s planned for an “unveiling” of their $250 million dollar solar farm on Thursday, but it was canceled abruptly due to a security concern.

WSBT reports the threat involved a former employee.

The solar farm spans more than 1,100 acres near New Carlisle, is set to produce 188 megawatts of energy as it begins commercial operation.

The farm, located on a local family’s land, also has sheep grazing among the solar panels.

The farm will generate enough power for over 35,000 homes, with each megawatt providing energy for around 190 homes.
