Comments –
Sulfur hexafluoride (SF6) is roughly 22,800 times more potent than carbon dioxide at trapping heat over one hundred years and can remain in the atmosphere for up to 3,200 years. It’s used the standard insulator in electrical transmission and distribution equipment, and as a refrigerant and a fire suppressor. (It’s also been used to fill tennis balls…)

Summary –
The bill adds assessing the volume of sulfur hexaflouride in the state’s gas-insulated electrical equipment, and an estimate of the potential greenhouse gas emissions from it to Commerce’s biannual report to the Legislature. It adds utilities’ investments in any projects that reduce these emissions during the equipment’s useful life and when retired from service to the list of energy transformation projects they can count as offsets in providing “carbon-neutral” power during the period between 2030 and 2045 when that’s required by the Clean Energy Transformation Act.
