(a) In elections held by the election committee to elect members to the authority, each political subdivision entitled to representation on the election committee shall have and shall be entitled to have its representative on the election committee cast one whole vote plus an additional vote or votes (including fractions thereof) to be determined as provided in this subsection. The percentage which is arrived at by dividing the number of kilowatt hours taken from Georgia Power Company by each such political subdivision during the immediately preceding calendar year by the total number of kilowatt hours taken from Georgia Power Company by all such political subdivisions during the immediately preceding calendar year shall be determined; and each such percentage shall then be applied to a total number of votes equal to the total number of political subdivisions entitled to representation on the election committee. The resulting figure, calculated to the nearest one-thousandth, shall be the additional vote or votes (including fractions thereof) to which each respective political subdivision is entitled.

(b) At such time as facilities of the authority are placed in commercial operation as determined by the authority and energy is being supplied by the authority to political subdivisions contracting with the authority, then and thereafter each such political subdivision entitled to representation on the election committee shall have and shall be entitled to have its representative on the election committee cast one whole vote plus an additional vote or votes (including fractions thereof) to be determined as provided in this subsection. The percentage which is arrived at by dividing the number of kilowatt hours taken from the authority by each such political subdivision during the immediately preceding calendar year by the total number of kilowatt hours taken from the authority by all such political subdivisions during the immediately preceding calendar year shall be determined; and each such percentage shall then be applied to a total number of votes equal to the total number of political subdivisions entitled to representation on the election committee. The resulting figure, calculated to the nearest one-thousandth, shall be the additional vote or votes (including fractions thereof) to which each respective political subdivision is entitled by reason of energy taken. Notwithstanding any other provision of this subsection, at the meeting of the election committee in the calendar year immediately following the calendar year in which such facilities are first placed in commercial operation, as determined by the authority, and energy is being supplied by the authority to such political subdivisions, the period of time upon which the determination shall be made of the additional vote or votes (including fractions thereof) to which the representatives of the election committee shall be entitled at such meeting shall be the remainder of the calendar year in which energy was first supplied to such political subdivisions, provided that such facilities have been in commercial operation, as determined by the authority, and energy has been supplied for a minimum of six months in the immediately preceding calendar year. If such facilities of the authority have not been in commercial operation, as determined by the authority, and if energy has not been supplied for a minimum of six months in the immediately preceding calendar year, such additional vote or votes (including fractions thereof) shall be determined by the number of kilowatt hours taken from Georgia Power Company in accordance with subsection (a) of this Code section. (c) The presence at any meeting of the election committee of representatives entitled to cast two-thirds of the total votes to which the election committee shall be entitled shall constitute a quorum of the election committee.
