Formula Rate Implementation Protocols
Section 1
General
a) SCE&G employs a Fonnula (found at Appendix A to Attachment H of SCE&G's
Tariff) to calculate its base transmission rates (for Network Integration Transmission
Service and Point-to-Point Transmission Service), which rates are recalculated annually,
by means of the Fonnula, in accordance with the Protocols set forth herein. SCE&G
employs an Annual Update Process, which annually refreshes the transmission rates
calculation by populating the Fonnula with current infonnation from SCE&G's FERC
Fonn No. I. SCE&G provides on the last page of these Protocols a time-line/chart
illustrating this Annual Update Process. The Annual Update Process does not effect
change to the Fonnula itself.
b) Inputs for the following components of the Fonnula are supported by SCE&G in
its initial submission of the Fonnula: (i) rate of return on common equity; (ii)
depreciation rates; and (iii) "Post Employment Benefits other than Pensions" pursuant to
the Statement of Financial Accounting Standards No. 106, Employers Accounting for
Postretirement Benefits Other than Pensions ("PBOP") charges. The values used in the
Fonnula for each of these components shall not be changed except pursuant to a filing
under Federal Power Act ("FPA") section 205 or 206; provided however, SCE&G may
make a limited FP A section 205 filing pursuant to the provisions of Section 6 of these
Protocols. Any other modifications to the Fonnula shall be made through an FPA section
205 or section 206 filing.
Section 2
Annual Update Process
a) The Annual Transmission Revenue Requirement ("ATRR") and the transmission
rates derived under the Fonnula shall be applicable to services on and after June 1 of a
given calendar year! through May 31 of the subsequent calendar year ("Rate Year").

(iii) submit such Annual Update to the Federal Energy Regulatory Commission
