4901:5-5-05 Energy and demand forecasts for electric utilities.

(A) General guidelines.

(1) The reporting person shall provide or cause to be provided data on the use of the electric utility's distribution lines and facilities.

(2) The reporting person shall specify in detail the methodology employed to produce monthly forecasts of energy and peak load for the current year and one year in the future.

(3) The reporting person shall, upon request, supply to the commission with additional data and maps of distribution lines and facilities.

(B) Distribution energy data and peak demand forecast forms.

The distribution forecast shall be submitted in an electronic form prescribed by the commission or its staff.

(1) Each electric utility shall file a certified territory energy forecast (megawatt-hours/year). Each electric utility operating in Ohio shall furnish completed sets of FE-D1 and FE-D2 forms:

(a) FE-D1 shall contain data for only the Ohio portion of the reporting electric utility's total certified territory.

(b) Electric utilities that are members of an integrated operating system and operated on a system basis shall also file FE-D2 for the integrated system.

(2) Each electric utility shall file Ohio and system seasonal peak load demand forecasts: Actual and forecast system peak demand levels for summer and winter seasons as displayed on forms FE-D3 and FE-D4, as follows:

(a) FE-D3 shall contain data for only the Ohio portion of the reporting electric utility's total certified territory.

(b) Electric utilities that are members of an integrated operating system and operated on a system basis shall also file form FE-D4 for the integrated system.

(3) Monthly forecasts of energy and peak loads.

The electric utility shall specify in detail the methodology employed to produce monthly forecasts of energy peak load and resources for the current year and one year in the future. The reporting electric utility shall provide or cause to be provided monthly information as required on the following forms:

(a) From FE-D5, monthly net energy for load forecast.

(b) Form FE-D6, monthly native and internal peak load forecasts.

(C) Substantiation of the planned distribution system.

The reporting electric utility shall submit a substantiation of distribution development plans, including:

(1) Load flow or other system analysis by voltage class of the electric utility's distribution system performance in Ohio, that identifies and considers each of the following:

(a) Any thermal overloading of distribution circuits and equipment.

(b) Any voltage variations on distribution circuits that do not comply with the current version of the American National Standard Institute (ANSI) standard C 84.1, electric power systems and equipment voltage ratings or standard as later amended.

(2) Analysis and consideration of proposed solutions to problems identified in paragraph (C)(1) of this rule.

(3) Adequacy of the electric utility distribution system to withstand natural disasters and overload conditions.

(4) Analysis and consideration of any studies regarding distribution system improvement, including, but not limited to, any studies of the potential for reducing line losses, thermal loading and low voltage or any other problems, and for improving access to alternative resources.

(5) A switching diagram of circuits less than one hundred twenty-five kV that are not radial.
