(a)electricity which they generate themselves; or
(b)electricity which they generate themselves together with electricity which is supplied to them by the holder of a licence under section 6(1)(c) of the Act;
and who do not at any time supply more electrical power than 500 kilowatts.
A.1. For the purposes of Class A electrical power supplied by a body corporate which is associated with any supplier shall be treated as supplied by that supplier.
Class B. Persons who do not supply any electricity except—
(a)electricity which is supplied to their premises by the holder of a licence under section 6(1)(c) or (2) of the Act or by a person in circumstances such that he falls within Class C in this Schedule (in this Class referred to as a “Class C supplier”) provided that for the purpose of determining for the purpose of this Class and paragraph B.1 below whether a person is supplying electricity in such circumstances paragraphs (2)(a) and (b) of Class C in this Schedule shall have effect as if the words following “is situated”, in each case, were omitted; or
(b)electricity which they generate themselves or which is supplied to them by a person authorised by an exemption to supply electricity when—

(ii)the plant or equipment which is used to generate electricity for the purpose of giving such a supply of electricity is being tested.
B.1.—(1) The exemption granted by this Order to persons falling within Class B (in this paragraph referred to as “exempt suppliers”) shall cease to be in force in relation to any exempt supplier—
(a)if he supplies Class C electricity to any premises other than in either of the circumstances specified in sub-paragraph (2) below;
(b)if he supplies section 6(2) electricity or Class C electricity to any premises in either of the circumstances specified in sub-paragraph (2) below and those premises are not on the same site as relevant premises;
(c)if during a relevant period he starts to make relevant supplies from any particular relevant premises from which he has not previously made relevant supplies and at the time he starts to make such supplies from those premises he does not reasonably expect that the total amount of relevant supplies made by him during the remainder of the relevant period in question from those relevant premises will be less than the lower of that amount which is obtained by multiplying the specified amount by a percentage equal to the percentage of that relevant period then remaining and 10 per cent. of the total amount of section 6(2) and Class C electricity supplied to those relevant premises in that relevant period;
(d)on 1st June in any year if the total amount of relevant supplies made by him in the preceding relevant period from any particular relevant premises exceeds the lower of—
(i)the specified amount or, in a case where the exempt supplier started to make relevant supplies from those relevant premises (from which he had not previously made relevant supplies) in that preceding relevant period, that amount which is obtained by multiplying the specified amount by a percentage equal to the percentage of that preceding relevant period remaining at the time he started to make such supplies; and
(ii)10 per cent. of the total amount of section 6(2) and Class C electricity supplied to those relevant premises in that preceding relevant period,
provided that for the purposes of sub-paragraphs (b) to (d) above no account shall be taken of any section 6(2) electricity which is supplied by or to the exempt supplier in question after 31st March 1998.
(2) The circumstances referred to in sub-paragraph (1) above are—
(a)in a case where the exempt supplier in question supplies section 6(2) or Class C electricity to existing premises, that during the previous period of twelve consecutive months the annual maximum power made available to those premises (whether by that exempt supplier or by anyone else) was 100 kilowatts or less, unless during some other period of twelve consecutive months the annual maximum power made available to those premises (whether by that exempt supplier or by anyone else) was more than 100 kilowatts;
(b)in a case where the exempt supplier in question supplies section 6(2) or Class C electricity to new premises, that the exempt supplier at the time when he supplies section 6(2) or Class C electricity to those premises does not reasonably expect that the annual maximum power which would be made available to those premises (whether by that exempt supplier or by anyone else) would be more than 100 kilowatts during the period of twelve consecutive months starting with the date on which those premises were first supplied with electricity (whether those premises were first supplied by the exempt supplier in question or by anyone else).

more electricity that is neither section 6(2) electricity nor, as the case may be, Class C electricity, than is supplied to those relevant premises during that relevant period or that month; or
any amount of electricity that is neither section 6(2) electricity nor, as the case may be, Class C electricity in circumstances where that would cause the exemption granted by this Order to cease to be in force;
premises supplied by an exempt supplier shall be treated as on the same site as relevant premises if they are—
the same premises;
immediately adjoining each other; or

(b)two or more consumers who form a qualifying group each of whom occupies premises which are on the same site as the premises where the generating station is situated and consumes all the electricity provided to him by the supplier in question at those premises other than any of that electricity supplied by that consumer in circumstances such that he falls within Class B in Schedule 3; or
(c)(i)consumers of the type specified in sub-paragraphs (a) or (b) above; and
(ii)any other person in circumstances where the provision of the output of the generating station in question does not amount to the supply of electricity to any premises,

(a)is purchased by that person pursuant to the pooling and settlement agreement; and
(b)does not exceed the amount of electricity which he generates at that station in that half hour and which he is required to sell and does sell pursuant to that agreement.
C.1. Where at any time the supplier in question and some other person generate electricity at the same generating station at the same time, the generation of electricity by that other person and the provision of the output of that generating station by that other person shall for the purposes of Class C be treated as the generation of electricity by that supplier if that other person, being a body corporate, is associated with that supplier.

“output” in relation to a generating station means the electricity generated at that generating station other than electricity consumed by the plant.
(2) For the purposes of Class C and paragraph C.1 above—
(a)two or more generating sets which are operated by the same person or by bodies corporate which are associated with each other shall be treated as a single generating station if they are on the same site as each other (whether or not there is an electrical interconnection between any of them) but otherwise shall be treated as separate generating stations, and in this sub-paragraph—
