The OEB has issued a letter which sets out the Inflation Parameter Updates for Incentive Rate-Making Applications with Rates effective in 2021. The OEB notes that it is not mandatory that the calculated inflation factor be adopted for rate adjustments. In light of the current COVID-19 pandemic, the OEB is providing utilities to adopt an inflation factor less than that calculated by the OEB’s methodology for each sector. Utilities applying for 2021 rate adjustments must inform the OEB of their choice in accordance with the directions in the letter.
