The ACR methodology for Reduction in Emissions from the Recycling of Transformer Oil is inactive and ineligible for crediting projects on ACR. ACR has determined that the methodology requires updates to be consistent with the current version of the ACR Standard.

The methodology was developed by Hydrodec Group PLC. The methodology quantifies emission reductions achieved in the U.S. by diverting used transformer oil, which under normal conditions would be incinerated at the end of its useful life, to a refining facility that processes the transformer oil for re-use. Project Proponents achieve emissions reductions by recycling the highly refined oil used in transformers that are operated by electric utility customers and large industrial companies. As a co-benefit, recycling of transformer oil in controlled and permitted facilities reduces the environmental health and safety risks associated with the destruction of Polychlorinated Biphenyls (PCBs) found in transformer oil.
