A legacy of

Pride in our past, confidence in our future

In 1998, Sempra was formed as a merger of two century-old utilities: Pacific Enterprises and Enova Corporation, the parent companies of Southern California Gas Co. and San Diego Gas & Electric Co. Since day one, we’ve chosen to look at the world — and how we deliver energy — differently. We’ve pursued a path of technology, innovation and talent, always keeping in mind our stakeholders, consumers and communities.

In our 25+ years, we’ve persevered to overcome many obstacles — including economic downturns and the COVID-19 pandemic — and emerged stronger. We’ve also accomplished significant milestones, including the launch of one of the first LNG terminals on the West Coast, the creation of the Sempra Foundation and the installation of the first power-to-gas project in the U.S. We’ve come a long way since our ambitious beginning on June 28, 1998. And while we’re celebrating our legacy of success, we’re also finding inspiration for the next 25 years.

Sempra Foundation expanded energy access

Throughout the year, Sempra Foundation funded multiple projects to expand energy access in under-resourced communities in Mexico and along the U.S.-Mexico border. In late 2022, a group of Sempra employees volunteered their time to help deliver and assemble a biodigester and cleaner cookstoves in communities across Baja California, Mexico.

With the help of another nonprofit partner, the Foundation also provided solar photovoltaic systems to families in rural, unincorporated, underserved communities along the Texas-Mexico border. The affordable electricity provided by the solar panels makes it possible for the families to heat and cool food and water, study and complete schoolwork after dark, and more.
