Energizing San Diego for over 140 years

When five San Diegans met in the parlor of the Consolidated Bank on April 18, 1881, to incorporate the San Diego Gas Company, they formed a successful enterprise that would serve a fledgling city whose population had just passed 3,000. They quickly asked that the city trustees authorize the purchase of 25 streetlamp posts, the first ones to be maintained for public use.

Today, San Diego’s 99,000 plus streetlights serve the eighth-largest city in the country. Could they have believed that their company’s gas customers would grow from an original 89 to 905,000, and electric customers from none to 3.7 million?
