In 2012, DLR Group partnered with NRG Energy to design and install a "Solar Ring" on the upper rim of MetLife Stadium. The Solar Ring consists of 1,350 building integrated photovoltaic (BIPV) solar panels assembled into 47 individual frames. The BIPV panels are illuminated with LED lighting and programmed to display the signature blue and green colors of the Giants and the Jets along with other hues for events such as concerts, soccer matches and college sports. The panels generate about 350 KW, nearly 25 times the amount of electricity that's actually needed to power the LED display system. The excess power generated can go into the general stadium use or back to the grid.
