Connecticut’s largest privately held construction and heavy building materials producer recently turned the switch on a 1.3-megawatt solar array at its Southbury quarry, ready mixed concrete and asphalt operation. O&G Industries couples the 3,762-panel installation with a 280-kilowatt energy storage system that will augment power supply during peak demand cycles—especially early morning hours when the sun isn’t strong enough to keep the array at full output while concrete, aggregate and asphalt production startup spikes electricity use.
