SAN JUAN, Puerto Rico - OG&E has restored power to an elementary school in Puerto Rico. 

After five long months without electricity, the school is back on the grid, and students and teachers couldn't be happier. 

On Monday, OG&E posted a video to Facebook. Around 400 students and teachers at Esculent Elemental Luis Felipe Rodrigues School cheered when the power was flipped back on.

A second wave of OG&E linemen deployed earlier in February to continue efforts to restore power, working 19 hours days to help as many people as possible.

Grateful residents have been cheering them on along the way.

This wave of linemen is expected home later this week.
