Saudi Arabia will host Formula E's first ever night race with a double-header in Diriyah next February, the all-electric series announced on Tuesday.
Organisers said low consumption LED floodlights would be powered by fully renewable energy, using low-carbon certified hydrogenated vegetable oil made from sustainable materials.
Diriyah has hosted Formula E since 2018 and next year's races will be the third and fourth in a championship that starts in Chile.
Saudi Arabia is also due to host a Formula One race for the first time next year and that will also be at night, in Jeddah in November.
