General Rate Act 1967

PART I CALCULATION OF RATEABLE VALUE ON WHICH RATES ARE TO BE ASSESSED

Rateable value of notional hereditament

1 The rateable value for any year of the hereditament which, by virtue of section 34(3) of this Act, an Electricity Board are to be treated as occupying in any rating area 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.

Valuation of activities

2 (1) The value of an Electricity Board's distribution or generating activities for a rating area shall be an apportioned part of the aggregate value of the Board's distribution or, as the case may be, generating activities, and, subject to sub-paragraph (2) of this paragraph, 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.

(2) Subject to paragraph 16 of this Schedule, the Minister may by order provide that the apportionment required by sub-paragraph (1) of this paragraph, shall in the case of all Electricity Boards or any Electricity Board specified by the order, instead of being made as provided by paragraphs (a) and (b) of that sub-paragraph, be made as provided by the order.

Determination of aggregate value of activities

3 (1) In the case of the Generating Board, the aggregate value of the generating and distribution activities of the Board for any year shall each be taken to be one half of the Board's basic value for that year:

Provided that, subject to paragraph 16 of this Schedule, the Minister may by order provide that the foregoing provisions of this sub-paragraph shall have effect as if for the reference to one half there were substituted references to such other fractions as may be specified by the order in relation to the Board's generating activities and distribution activities respectively.

(2) In the case of an Area Board—

(a) the aggregate value of the generating activities of the 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 ;

(b) the aggregate value of the distribution activities of the Area Board shall be taken to be the Board's basic value for the year reduced, in the case of a Board carrying on generating activities, by the aggregate value of the generating activities.

Determination of Board's basic value

4 The basic value of an Electricity Board for any year shall be their share of the basic electricity rateable value determined in accordance with paragraph 5 of this Schedule adjusted as mentioned in paragraph 6 of this Schedule 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 31st 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.

5 (1) Subject to sub-paragraph (2) of this paragraph, the basic electricity rateable value shall be taken to be £47,212,610; and the share thereof of each respectively of the Electricity Boards set out in the following table shall be the percentage of that sum so set out in relation to that Board.

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

(2) 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 sum which under sub-paragraph (1) of this paragraph is to be taken 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.

6 The adjustment mentioned in paragraph 4 of this Schedule 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 said paragraph 4 or, as the case may be, decreased by one-fifth of the deficiency so mentioned, and the denominator is the Board's standard output.

Meaning of " output " and " standard output "

7 For the purposes of the foregoing provisions of this Schedule, the standard output of the Generating Board is the output of the Central Electricity Authority in the twelve months ending with 31st December 1957, as calculated and certified by the Generating Board, and the standard output of any Area Board is the ouput of that Board in that twelve months, as calculated and certified by that Board; and the expression " 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.

Provisions as to generating activities and capacity

8 (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 if) on 31st 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 31st 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 31st 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 sub-paragraph (3) of this 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.

Provisions as to aggregate net annual value

9 (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 the net annual value of every hereditament the rateable value of which appears in the valuation list for the area on 1st April in the preceding year other than any hereditament so appearing in pursuance of, or of the enactment re-enacted by, section 33(3) and 34(3) of this Act, 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.
