Con Edison releases study of climate impacts to energy systems
Con Edison, in collaboration with ICF and Columbia University’s Lamont-Doherty Earth Observatory, recently released a study evaluating historical and projected climate-driven impacts on Con Edison’s energy delivery systems through the 21st century.
The New York State Public Service Commission (NYPSC) authorized the 36-month study as part of a collaborative created after Superstorm Sandy.
“We recognize the global scientific consensus that climate change is occurring at an accelerating rate,” Tim Cawley, president of Con Edison, said. “While climate change’s exact pace and effects are uncertain, the study provides a strong foundation upon which to plan, design, and invest in our energy delivery systems to better protect them and serve our customers.”
The analysis considered various potential climate futures, including unabated and reduced greenhouse gas concentrations, as well as extreme “stress test” scenarios.
The analysis identified sea level rise, coastal storm surge, inland flooding from intense rainfall, hurricane-strength winds, and extreme heat as the most significant climate-driven risks to Con Edison’s systems.
The report estimates Con Edison may need to invest between $1.8 billion and $5.2 billion by 2050 in targeted programs to protect its delivery systems and customers from climate change impacts. The company typically invests approximately $3 billion each year in its energy infrastructure. It will further assess adaptation strategies and associated costs by developing five, 10, and 20-year plans.
Con Edison said that its next step would be to develop a Climate Change Implementation Plan by the end of 2020 based on the recommendations of the Climate Change Vulnerability Study. The company will work with a stakeholder group for input on scope and to provide updates quarterly.
“In the face of a changing climate, advancing resilience is crucial for maintaining critical infrastructure services,” ICF Senior Vice President Anne Choate said. “This report reflects Con Edison’s commitment to understanding physical climate risks and builds a rich foundation for implementing resilience solutions. ICF appreciates the opportunity to partner with Con Edison throughout this landmark study; this effort will serve as a benchmark for utilities around the country.”
