The Physical Risks Associated with Climate Change May Have an Adverse Impact on Our Business Operations, Financial Condition and Cash Flows.

Physical risks of climate change such as flooding, wildfires, rising sea levels, and other related phenomena, resulting from more frequent or more extreme weather events and changes in temperature and precipitation patterns associated with climate change, could affect some, or all, of our operations. Frequent or extreme weather events could disrupt our operations and/or be destructive, which could result in increased costs, including supply chain costs. An extreme weather event within the Electric Companies’ and Transmission Companies’ service areas could also directly affect their capital assets, such as downed wires, poles, or damage to other operating equipment, resulting in service disruptions to customers and possibly creating hazardous conditions. Further, as extreme weather conditions increase system stress, we may incur costs relating to additional system backup or service interruptions, and in some instances, we may be unable to recover such costs. For all of these reasons, these physical risks could have an adverse financial impact on our business operations, financial condition and cash flows.

Climate change poses other financial risks as well. To the extent weather conditions are affected by climate change, customers’ energy use could increase or decrease depending on the duration and magnitude of the changes. Increased energy use due to weather changes may require us to invest in additional system assets and purchase additional power. Additionally, decreased energy use due to weather changes may affect our financial condition through decreased revenues, margins or earnings.
