Climate Goals & Targets

Environmental Challenges

• Sea level rise and storm surge
• Warmer temperatures and more frequent heat waves
• Changes in extreme weather patterns
• Increasing risk of wildfires
• Increasing risk of landslides and erosion
• Reduced snowpack and changes in runoff timing
• Higher peak streamflows and flood risk
• Lower summer streamflows

Mitigation Strategies

• Make spatial information on projected sea level rise and storm surge readily available.
• Consider establishing a utility-wide policy to identify future impacts of tidal flooding.
• Expand Seattle City Light’s analysis of the relationship between warming temperatures, seasonal base and peak load, and air conditioning use.
• Identify and evaluate potential co-benefits of existing energy-efficiency programs.
• Assess the potential of demand response for reducing peak commercial load.
• Monitor and consider replacing equipment in the transmission and distribution system that is more sensitive to corrosion by salt water.
• Monitor failures of and damage to underground cables.
• Expand the use of the Outage Management System (OMS).
• Increase the capacity of employees to prepare for and respond to increasing wildfire risk.
• Collaborate with adjacent land owners to reduce flammable vegetation.
• Collaborate with state resource management agencies and academic institutions to map landslide risk.
• Upgrade current transmission infrastructure to be resilient to higher peak flows.
• Update and expand the utility’s analyses of how operations of the Skagit and Boundary Projects could be adapted.
• Collaborate with Seattle Public Utilities to evaluate the effects of changes in snowpack and streamflow timing.
• Consider further diversification of Seattle City Light’s power resources.
• Consider increases in peak flows and lower summer flows directly in prioritizing acquisitions of habitat mitigation lands.
