53.—(1) An order under Article 52 may make provision generally in relation to the renewables obligation imposed by the order, and may in particular specify—
(a)different obligations for successive periods of time;
(b)that only electricity generated using specified descriptions of renewable source is to count towards discharging the obligation (or that such electricity is to count only up to a specified amount);
(c)that only electricity generated by specified descriptions of generating station is to count towards discharging the obligation (or that such electricity is to count only up to a specified amount);
(d)that a specified minimum amount of electricity generated as mentioned in sub-paragraph (b) or (c) is to be counted towards the discharge of the renewables obligation;
(e)how the amount of electricity supplied by an electricity supplier (whether generally or to particular customers or descriptions of customer) is to be determined;
(f)how the proportion referred to in Article 52(5) or in the definition of “renewable sources” in Article 52(7) is to be determined;
(g)the consequences for the discharge of the renewables obligation if a generating station of the type mentioned in Article 52(5) uses more than a specified proportion of fossil fuel or peat during a specified period (which may include the consequence that none of the electricity generated by that generating station during that period is to count towards discharging the obligation);
(h)that specified information, or information of a specified nature, is to be given to the Authority (in addition to the evidence referred to in Article 52(2)), and the form in which it is to be given.
(2) An order may, in relation to any specified period (“the current period”)—
(a)provide that evidence of electricity supplied in a later period may, when available, be counted towards discharging the renewables obligation for the current period;
(b)provide that evidence of electricity supplied in the current period may, in a later period, be counted towards discharging the renewables obligation for that period;
(c)specify how much later the later period referred to in sub-paragraph (a) or (b) may be;
(d)specify a maximum proportion of the renewables obligation for any period which may be discharged as mentioned in sub-paragraph (a) or (b);
(e)specify a maximum proportion of electricity supplied in any period evidence of which may be counted towards discharging the renewables obligation for a different period.
(3) An order may make any provision capable of being made under section 2(2) of the European Communities Act 1972 (c. 68) in connection with European Parliament and Council Directive 2001/77/EC on the promotion of electricity produced from renewable energy sources in the internal electricity market.
(4) An order may make—
(a)different provision for different cases or circumstances; and
(b)different provision in relation to different electricity suppliers,
if the Department is of the opinion that the differences are such that no electricity supplier would be unduly disadvantaged in competing with other electricity suppliers.
(5) An order may provide for the Authority to require an electricity supplier to provide it with information, or with information of a particular kind, which is in its opinion relevant to the question whether the supplier is discharging, or has discharged, the renewables obligation.
(6) That information must be given to the Authority in whatever form it requires.
(7) No person shall be required by virtue of this Article to provide any information which he could not be compelled to give in evidence in civil proceedings in the High Court.
(8) An order may make further provision as to the functions of the Authority in relation to the obligation imposed by the order.
