1For any year, the rateable value of the hereditament which an Electricity Board is to be treated as occupying in any rating area as mentioned in subsection (1) of section twelve of this Act shall be the value of the distribution activities of the Board for that area and year, increased, in the case of a Board carrying on generating activities in the area, by the value for that area and year of the generating activities of the Board.
2The value of the said activities for a rating area shall be an apportioned part of the aggregate value of the activities, and the apportionment shall be made—
(a)in the case of distribution activities, by reference to the aggregate net annual value of the rating area, or so much thereof as is comprised in the area of the Board, and of the area of the Board,
(b)in the case of generating activities, by reference to the generating capacity of the Board in the rating area and the aggregate generating capacity of the Board.
3(1)The aggregate value of the generating and of the distribution activities of the Generating Board shall each be taken to be one half of the Board's basic value for the year (as hereinafter determined).
(2)The aggregate value of the generating activities' of an Area Board shall be taken to be an amount which bears to the aggregate value of the generating activities of the Generating Board the same proportion as the aggregate generating capacity of the Area Board bears to the aggregate generating capacity of the Generating Board, and the aggregate value of the distribution activities of an Area Board shall be taken to be the Board's basic value for the year (as hereinafter determined) reduced, in the case of a Board carrying on generating activities, by the aggregate value of the generating activities.
4(1)The basic value of an Electricity Board for any year shall be determined as follows.
(2)As soon as may be after the passing of this Act the Minister shall certify to each Electricity Board the amount which is to be the basic electricity rateable value.
(3)The amount to be certified by the Minister as the basic electricity rateable value shall be the amount estimated by him to represent the amount of the payment in lieu of rates made or to be made for the benefit of local authorities by the Electricity Council under Part V of the Act of 1948 in respect of the year 1958-59—
(a)multiplied by the fraction of which the numerator is the estimated rateable value for England and Wales for that year and the denominator is the estimated aggregate gross charge to rates for England and Wales for that year, and
(b)reduced by the estimated aggregate net annual values at the beginning of the year 1959-60 of all premises in respect of which the Electricity Council or an Electricity Board will by virtue of Part I of this Act then become liable to be rated,
and adjusted in such manner as appears to the Minister to be proper having regard to any other relevant considerations.
(4)For the year 1959-60 the basic value of an Electricity Board shall be its share of the basic electricity rateable value, that is to say the percentage of that value set out in the following table.
| Electricity Board | Percentage |
|---|---|
| Generating Board | 50.000 |
| London Area | 7.055 |
| South Eastern Area | 3.454 |
| Southern Area | 4.256 |
| South Western Area | 2.073 |
| Eastern Area | 4.949 |
| East Midlands Area | 4.204 |
| Midlands Area | 4.990 |
| South Wales Area | 2.359 |
| Merseyside and North Wales Area | 3.047 |
| Yorkshire Area | 4.972 |
| North Eastern Area | 3.107 |
| North Western Area | 5.534 |
(5)For any subsequent year the basic value of an Electricity Board shall be its share of the basic electricity rateable value adjusted as hereinafter mentioned by reference to the excess or deficiency of the Board's output, as calculated and certified by the Board, in the twelve months ending with the thirty-first day of December falling next but one before the beginning of the year for which the basic value is being ascertained, as compared with the Board's standard output, as hereinafter defined.
(6)The adjustment mentioned in the foregoing sub-paragraph shall be effected by multiplying the Board's share of the basic electricity rateable value by the fraction of which the numerator is the Board's standard output increased by one-fifth of the excess mentioned in the foregoing sub-paragraph or, as the case may be, decreased by one-fifth of the deficiency therein mentioned, and the denominator is the Board's standard output.
(7)For the purposes of the foregoing sub-paragraph the standard output of the Generating Board is the output of the Central Electricity Authority in the twelve months ending with the thirty-first day of December, nineteen hundred and fifty-seven, as calculated and certified by the Generating Board, and the standard output of any Area Board is the output of that Board in that twelve months, as calculated and certified by that Board ; and for the purposes of this paragraph " output "—
(a)in relation to the Central Electricity Authority or the Generating Board, means the total number of units of electricity supplied by the Authority or Board to Area Boards or direct to consumers in England and Wales ;
(b)in relation to an Area Board, means the total number of units of electricity purchased or generated by the Board for supply direct to consumers, together with the estimated number of units of electricity supplied by the South of Scotland Electricity Board direct to consumers in the area of the Area Board, as certified by the South of Scotland Electricity Board.
(8)If it appears to the Minister that by reason of any substantial change of circumstances it is expedient so to do, he may by order made after consultation with the Electricity Council and with such associations of local authorities as appear to him to be concerned, and with any local authority with whom consultation appears to him to be desirable, vary the amount which for the purposes of this Schedule is to be the basic electricity rateable value, but an order under this sub-paragraph shall not have effect until approved by a resolution of each House of Parliament.
Any order under this sub-paragraph may be varied or revoked by a subsequent order made in the like manner and subject to the like provisions.
5(1)For the purposes of this Schedule an Electricity Board shall be treated, as respects any year, as carrying on generating activities, or carrying on such activities in a particular area, if (but only (f) on the thirty-first day of March falling next but one before the beginning of that year there was a generating station in commission for operation by the Board, or as the case may be, there was a generating station in commission as aforesaid in that area.
(2)For the purposes of this Schedule the generating capacity or aggregate generating capacity of an Electricity Board for any year shall be taken to be the installed capacity or aggregate installed capacity, that is to say the maximum amount of electricity, as certified by the Board, capable of being generated in the station or stations in question at the thirty-first day of March falling next but one before the beginning of that year; and the said maximum amount shall be certified on the footing that all generators which were installed at any thirty-first day of March were capable of being fully used at that time.
(3)For the purposes of this Schedule a generating station situated partly in one rating area and partly in one or more other rating areas shall be treated as situated in each of the areas and its generating capacity, on any date, shall be treated as apportioned between the areas in such manner as may be agreed between the rating authorities of the areas and the Electricity Board.
(4)If the apportionment required by the foregoing sub-paragraph has not been agreed before the end of the month of September following the date as at which it is to be made, it shall be made by the Minister and notified by him to the rating authorities and the Board as soon as may be after the end of that month.
(5)For the purposes of this Schedule any group of premises lying within one curtilage and occupied for the purposes of the generation of electricity shall be treated as one generating station; and a group of premises shall not be treated as not lying within one curtilage by reason only that it is traversed by a public highway or inland waterway.
6(1)For the purposes of this Schedule the aggregate net annual value of a rating area for any year shall be taken to be the aggregate, as estimated and certified by the Commissioners of Inland Revenue (hereinafter referred to as " the Commissioners") of the rateable value (or, where that value differs from the net annual value, of the net annual value) of every hereditament the rateable value of which appears in the valuation list for the area on the first day of April in the preceding year, other than any hereditament so appearing in pursuance of section twelve of this Act or section six of the Act of 1955, and of the values appearing to the Commissioners to represent the net annual values of hereditaments occupied by or on behalf of the Crown.
(2)For the purposes of this Schedule the aggregate net annual value for any year of the area of an Electricity Board, or of any part of a rating area of which part only is comprised within the area of an Electricity Board, shall be ascertained by such aggregation or apportionment as may be required; and any apportionment under this sub-paragraph shall be made, and the result thereof certified, by the Commissioners.
(3)References in this Schedule to the area of an Electricity Board shall be construed, in relation to the Generating Board, as references to the whole of England and Wales.
