Title 21A.

Body

STATEMENT OF FACTS:

1. Battery energy storage systems play a crucial role in modern energy supply by providing efficient and flexible storage for electricity generated from renewable energy sources, such as solar and wind power. They help address the intermittent nature of these sources by storing excess electricity during times of low demand and releasing it when demand is high. This enhances grid stability and reliability when implemented on a region-wide scale, and increases the reliability of electricity supply for individual uses when installed to back up consumer-scale renewable energy generation systems.

2. By making renewable energy sources more reliable, battery energy storage systems can help King County meet its Strategic Climate Action Plan goal of reducing greenhouse gas emissions in the county by eighty percent by 2050.

3. The use of battery energy storage systems has been rapidly increasing worldwide due to advancements in battery technology, decreasing costs, and the growing adoption of renewable energy generation. The deployment of large-scale battery energy storage systems has witnessed substantial growth in recent years, driven by both utility-scale installations and distributed systems at residential, commercial, and industrial levels.

4. Because widespread use of these systems is a relatively recent phenomenon, there are not currently regulations in King County’s zoning code that specifically address them.

4. While battery energy storage systems offer the advantages cited above, there are also potential risks associated with this technology. Fire and explosion incidents have been reported at battery energy generation facilities in the Unites States and abroad, arising from the nature of the battery chemistry and the large energy storage capacity.

5. The Washington Administrative Code recognizes this potential danger and includes new requirements, effective October 2023, intended to minimize the risk of fire and explosion doing damage to nearby structures and properties.

6. While these measures are important at minimizing damage should a catastrophic incident occur, it is important that the owners of battery energy storage systems carry financial responsibility, such as insurance, that will cover costs associated with such an incident, as well as any costs associated with decommissioning that facility at the end of its useful life.
