The Authority may from time to time direct that the maximum prices at which electricity supplied by authorised suppliers may be resold—
shall be such as may be specified in the direction; or
shall be calculated by such method and by reference to such matters as may be so specified;
and shall publish directions under this section in such manner as in its opinion will secure adequate publicity for them.
A direction under this section may—
require any person who resells electricity supplied by an authorised supplier to furnish the purchaser with such information as may be specified or described in the direction; and
provide that, in the event of his failing to do so, the maximum price applicable to the resale shall be such as may be specified in the direction, or shall be reduced by such amount or such percentage as may be so specified.
Different directions may be given under this section as respects different classes of cases, which may be defined by reference to areas or any other relevant circumstances.
If any person resells electricity supplied by an authorised supplier at a price exceeding the maximum price determined by or under a direction under this section and applicable to the resale—
the amount of the excess; and
if the direction so provides, interest on that amount at a rate specified or described in the direction,
shall be recoverable by the person to whom the electricity was resold.
