October 15, 2009 - FERC revises its regulations governing interest rates used in calculating refunds to reflect a change in the Federal Reserve's publications. The methods for calculating refunds or for determining the applicable interest rates are not being altered in any way. Order No. 727

The Commission, on a quarterly basis, publishes interest rates for oil, natural gas, and electricity for determination of refund purposes. The interest rates on this page as well as the archived rates are the same for oil, natural gas, and electricity. Please note that the interest rates for oil apply only as far back as 1983.

• Electric Interest Rates are Calculated in Accordance with Section 35.19a of the Commission's regulations
• Gas Interest Rates are Calculated in Accordance with Section 154.501(d) of the Commission's regulations and its predecessors
• Oil Interest Rates are Calculated in Accordance with Section 340.1(c)(2) of the Commission's regulations
