Definitions

2.—(1) In these Regulations, unless the context otherwise requires —

“fuel” means any substance which may from time to time be utilised by the Board as a source of energy for generating electricity;

“high tension supply” means electricity supply of 6,000 volts and above;

“high tension consumer” means a consumer receiving high tension supply from the Board;

“kW maximum demand” means the kW demand integrated over periods of 30 minutes except that the Board may in respect of any particular consumer have the kW maximum demand integrated over periods other than 30 minutes;

“low tension supply” means electricity supply of less than 6,000 volts;

“low tension consumer” means a consumer receiving low tension supply from the Board;

“off-peak period” means the period between 11 p.m. and 7 a.m. the following day;

“peak period” means the period between 7 a.m. and 11 p.m.;

“unit” means one kilowatt hour.

(2) Each point of supply shall be considered separately for the purposes of the application of the tariffs set out in the Schedule.

Prices

3.—(1) The prices of electricity supplied by the Board shall be in accordance with the tariffs set out in the Schedule.

(2) The prices in paragraph (1) shall be increased or decreased by 0.033 cent for each kWh for every dollar per tonne increase or decrease in the cost of fuel to the Board.

(3) The increase or decrease in the cost of fuel to the Board shall be calculated on a basic fuel price of $260 per tonne for a calorific value of approximately 43,030 kilojoules per kilogram.

(4) For the purposes of paragraph (2), the Board may, by notification in the Gazette, declare from time to time the increase or decrease in the cost of fuel to the Board.

Metering

4.—(1) All consumers shall be metered at the voltage at which electricity is supplied.

(2) The Board shall meter high tension supply at high tension, and low tension supply at low tension.

(3) Notwithstanding paragraphs (1) and (2), the Board may, until such time as the changeover of metering arrangements have been completed, meter high tension consumers at low tension and low tension consumers at high tension.

(4) Where metering arrangements are made pursuant to paragraph (3) —

(a)	the kWh used for billing low tension consumers so metered shall be the sum of kWh metered at high tension within the metering period less 2.5%; and
(b)	the kWh, kW and RkVAh used for billing high tension consumers so metered shall be the sums of the kWh, kW and RkVAh respectively metered at low tension within the metering period plus 2.5%.

General tariff

5. The general tariff set out in Part I of the Schedule shall apply to low tension supplies to all premises.

High tension tariff

6. The high tension tariff set out in Part II of the Schedule shall apply to high tension supplies to all premises.

High tension consumers

7. A high tension consumer shall pay a maximum demand charge, running charge and declared demand charge.

Maximum demand charge

8.—(1) The maximum demand charge payable by a high tension consumer is the charge based on kW maximum demand.

(2) The maximum demand charge payable by a high tension consumer in any month shall be increased by 1% for each 1%, or a fraction thereof, by which the average lagging power factor in that month is less than 85%.

(3) For the purposes of this regulation, average lagging power factor shall be computed from the readings of the kWh and RkVAh meters.

Declared demand charge

9.—(1) The declared demand charge, which is based on a consumer’s chargeable declared kW, shall be paid by a high tension consumer if in any month the consumer’s kW maximum demand is less than 50% of his declared demand. The consumer’s chargeable declared kW shall be the difference by which the consumer’s kW maximum demand is less than 50% of the consumer’s declared demand.

(2) The declared demand charge shall be payable with effect from the date the Board’s plant and equipment are available to provide the consumer’s declared demand notwithstanding that the service cable has not been installed and electricity supplies have not been turned on for the consumer.

Consumer’s declared demand

10.—(1) For the purposes of regulation 9, “declared demand” means the supply capacity a consumer has requested the Board to provide and such declared demand shall be deemed to be the consumer’s requirements for a period of 5 years from the date the Board’s plant and equipment, except for the service cable, are available to provide such declared demand (referred to in this regulation as the 5-year period).

(2) On the expiration of the 5-year period, the consumer may reduce his declared demand by giving the Board one month’s notice in writing and such reduced declared demand shall be deemed to be the consumer’s requirements commencing from the first day of the month following the month in which the notice expires.

(3) A consumer may at any time with the approval of the Board increase his declared demand —

(a)	within the 5-year period by giving the Board notice in writing and such increased declared demand shall, subject to paragraph (5), be deemed to be the consumer’s requirements until the expiration of the 5-year period; or
(b)	after the 5-year period by giving the Board notice in writing and such increased declared demand shall, subject to paragraph (5), be deemed to be the consumer’s requirements for a further period of one year commencing from the date of approval during which the consumer shall not reduce his declared demand.

(4) Where the consumer’s actual kW maximum demand exceeds his declared demand —

(a)	at any time within the 5-year period, such kW maximum demand shall, subject to paragraph (5), be deemed to be the consumer’s declared demand until the expiration of the 5-year period; or
(b)	at any time after the 5-year period, such kW maximum demand shall, subject to paragraph (5), be deemed to be the consumer’s declared demand for a further period of one year commencing from the first day of the month during which the consumer’s actual kW maximum demand has exceeded his declared demand and during that year the consumer shall not reduce his declared demand.

(5) Where the Board has to provide additional plant and equipment to meet any increase in declared demand under paragraph (3) or (4), the increased declared demand shall, notwithstanding those paragraphs, be deemed to be the consumer’s declared demand for a further period of 5 years commencing from the date the Board’s plant and equipment, except the service cable, are made available to provide such increased declared demand (referred to in this regulation as the additional 5-year period).

(6) Any consumer who terminates an agreement for the supply of electricity during a 5-year period or an additional 5-year period shall pay the declared demand charge for the unexpired portion of the 5-year period or additional 5-year period, as the case may be.
