Green Button Best Practices from the OEB IWG

Best Practices Approved by the IWG

The IWG has approved Best Practices, which are guidelines supported by research and experience that lead to optimal outcomes when followed. They represent the most efficient or prudent course of action in a given business situation. In Ontario, the initial iteration of Green Button standards draws from past experiences with similar systems and lessons learned from other jurisdictions. The IWG recommends implementing these Best Practices where distributors can do so without undue burden or interfering with their other regulatory responsibilities, and where it does not contradict other utility best practices.

The IWG or its sub-working groups have publicly decided on these Best Practices at the IWG meetings. For other considerations discussed, please refer to the Non-Consensus Best Practices below. These Best Practices are publicly available on the OEB's Industry-Led Working Group pages at the Ontario Energy Board. We have made them easier to find and search, and this page will be updated as required. The OEB website is considered the source of the content, and if there is any discrepancy, please consider the OEB as the source of truth. If you find any missing Best Practices or differences from the OEB website, please contact us and we will consider your input and make the change as required.
