Sempra CSO: Decarbonization, resilience and affordability are the future of energy

Lisa Larroque Alexander of Sempra dives into the future of energy during a Climate Week interview

Modernizing transmission and distribution infrastructure and connecting them to new sources of energy are needed to help decarbonize economies and build resilience for customers, said Lisa Larroque Alexander, senior vice president of corporate affairs and chief sustainability officer for Sempra.

During a recent interview at the Intercontinental Exchange’s Climate and Capital Conference in New York City, Alexander told an audience of business, environmental and policy leaders that the first step to enabling the energy transition is to have a pragmatic conversation about what is possible and the importance of energy infrastructure.

“We need to go beyond the obvious and really understand energy systems because that’s going to help identify opportunities that others aren’t seeing that relate to enabling the energy transition,” Alexander said. “I think we need to have a functional conversation around the capabilities that our future energy systems need.”

The interview, led by Brian Matt, head of ESG Advisory for the New York Stock Exchange, focused on Sempra’s proactive approach to the evolving energy landscape.

Building resilience, embracing adaptation

Enabling the energy transition requires focus on three key issues, Alexander told Matt and the audience.

“The future of energy demands that we balance on a three-legged stool of decarbonization, resilience and affordability,” she said.

The balance is crucial because of increasing complexity of energy systems along with climate unpredictability, said Alexander.

In fact, in the U.S. alone, severe weather events each costing more than $1 billion have become the norm rather than the exception and they are happening less than every two weeks, according to the National Oceanic and Atmospheric Administration. A separate study by the International Energy Agency found that electric transmission and distribution infrastructure needs to expand by 2 million kilometers (or more than 124 million miles) per year with larger, newer and smarter infrastructure.

Alexander said Sempra is investing in innovations to make energy infrastructure even more agile and resilient to meet these challenges. By focusing on sustainable business practices, Sempra exemplifies an adaptive approach, where its operating companies are continually optimizing their operations to advance resilience and support communities, she said.

For example, Sempra California’s San Diego Gas & Electric (SDG&E) has been active in adding energy storage and microgrids to strengthen resiliency. Another Sempra California operating company, SoCalGas, has been a leading player in hydrogen technology, which plays a role in grid and energy reliability. Sempra Infrastructure, another Sempra operating company, is exploring the development of the Hackberry Carbon Sequestration facility, which is envisioned to capture approximately 2 million tons per annum (Mtpa) of carbon dioxide, with the company’s liquefied natural gas export project serving as the potential anchor customer.

The multiple development projects across Sempra’s operating companies work to tackle the energy transition with the three-pronged approach of decarbonization, resilience and affordability, Alexander said.

Sempra isn’t just passively reacting to changing times or natural disasters, the company is helping to set the pace of the energy transition with innovation and modernization, Alexander said.

“It’s a combination of technologies, both hardware and software, that allow us to better mitigate risk and build more resilient systems amid severe weather,” said Alexander.

Sempra California’s SDG&E is the owner of a privately-owned weather station network, which demonstrates Sempra’s overall commitment to harnessing technology for predictive modeling. This focus on technology not only underscores Sempra and its family of companies’ proactive stance, but also positions the company as a leading innovator that integrates cutting-edge solutions to help shape a more resilient and sustainable energy landscape.

What’s next for Sempra

Private and public financing and incentives — like those borne from the Inflation Reduction Act — are expected to be tailwind for Sempra’s business model.

“It’s going to create more demand and need for more capacity on our systems that in turn creates a significant investment case for us and other utilities in this space,” said Alexander.

Sempra’s focus on three growth platforms — California, Texas and Mexico, which combined represent the third largest GDP market in the world — means there are many robust opportunities for significant infrastructure investments. Sempra companies are currently executing a robust capital plan to help address the growing demand of safe and reliable energy, while enabling the energy transition.
