SF6 Mitigation Opportunities
The partnership has worked with partners to identify and develop several resources to highlight cost-effective methods of reducing SF6 emissions. Among other mitigation strategies, these include upgrading equipment to SF6-free circuit breakers to reduce SF6 use and leaks, establishing lifecycle approach for SF6 management, ensuring good management of SF6 acquisitions and gas inventory, training employees annually in SF6 handling and in using the necessary equipment, recycling SF6 gas at equipment servicing or disposal, implementing leak detection and repair strategies, and decommissioning equipment properly.
Alternatives to SF6
There are two new high voltage circuit breaker technologies that can be used as alternatives to traditional SF6 breakers and to review considerations for technology adoption. Based on testimonials and insights received from partner utilities and equipment manufacturers, the partnership developed a summary paper and hosted a webinar to provide an overview of the progress of these alternative technologies entering the market and considerations for technology adoption. Additionally, the partnership developed a calculator to evaluate the cost and GHG emissions benefits of switching to alternatives circuit breaker technologies.
