S.L. 545.41 Art. 9Network connection for multiple customers within one development.

(1) For the purposes of these regulations, multiple customers within one (1) development may consist of residential premises, non-residential premises, domestic premises, or a mixture of residential premises and, or non-residential premises and, or domestic premises. The connection fees payable for each network connection up to 60 Amps as established in the Sixth Schedule shall be applicable in respect of each network connection not exceeding 60 Amps to each building unit within a development with multiple customers.

(2) Where the number of connection units in a development with multiple customers does not exceed eighteen (18), and where the route length does not exceed three hundred metres (300m) from the nearest suitable substation, the network connection may by extended from the nearest suitable low voltage connection point or suitable substation, as determined by the distribution system operator.

(3) Where the number of connection units in a development with multiple customers does not exceed eighteen (18) and the route length is beyond three hundred metres (300m) from the nearest suitable low voltage connection point, the applicants shall pay for the full cost of the extension, including any civil works which may be required, less the applicable connection fee stipulated in item 1 of the Sixth Schedule. Where the voltage regulation goes beyond the limits established in the network code, a new substation shall be required for the network connection to the said development with multiple customers.

(4) New network connections for developments with multiple customers shall be provided by the distribution system operator by extending the network infrastructure from the nearest suitable substation, as determined by the distribution system operator, to the development, if all of the following criteria are satisfied:

(a) the number of connection units is more than eighteen (18) but does not exceed fifty (50);

(b) the route length from the nearest suitable substation does not exceed three hundred metres (300m);

(c) the product of the number of connection units and the route length in metres does not exceed six thousand and six hundred (6,600) connection unit metres;

(d) the peak load of the existing substation at the time of the application or consultation and the additional load estimated at the diversified load given in regulation 9(7), when taken into account in the aggregate, do not exceed seventy-five per cent (75%) of the transformer rating, as long as the transformer cannot be replaced by one with a larger capacity; and

(e) the development is within a building development zone:

Provided that when all the conditions in this regulation are satisfied, the connection fees payable for each network connection up to 60 Amps, as established in the Sixth Schedule, shall be applicable in respect of each network connection to each building unit within the development.

(5) Any civil works, such as but not limited to trenching and laying of cables, that may be required for the provision of a network connection pursuant to sub-regulation (4), and is other than bulk network connection, shall be carried out by the distribution system operator.

(6) Where the number of connection units in a development with multiple customers is more than eighteen (18) and any one (1) or more of the criteria in sub-regulation (4) are not satisfied, a new substation shall be required to provide the network connection to the relevant development with multiple customers, unless the distribution system operator determines, in its discretion, that a network connection extended from an existing substation, or another technical alternative, is adequate to:

(a) meet the total demand of the whole multiple customer development; and

(b) comply with the requirements of the network code.

(7) The number of connection units and load in a multiple customer development shall be calculated using the following parameters:

(a) a single phase 40 Amps network connection is considered as one (1) connection unit;

(b) a three phase 40 Amps network connection is considered as equivalent to three (3) connection units;

(c) a three phase 60 Amps network connection is considered as four-and-a-half (4.5) connection units;

(d) an industrial and, or commercial building unit shall be considered as four-and-a-half (4.5) connection units even when the application is for a single phase 40 Amps network connection;

(e) a car garage or parking space of up to fifty square 2 metres (50m ) shall be considered as one-half (0.5) connection units; and

(f) the diversified load for one (1) connection unit is taken as 16 Amps.

(8) A network connection for an individual customer within a multiple customer development shall be treated as a bulk network connection if it requires more than 60 Amps three phase and shall be extended in accordance with regulation 10:

(a) from an existing substation within the multiple customer development; and

(b) from a substation not within the multiple customer development:

Provided that the distribution system operator shall extend the low voltage connection to the multiple customer development on a cost-sharing basis with bulk network connection applicants and, or the developer, as applicable, which cost sharing is to be applied on a basis on the proportion of the kVA load used pro rata by the distribution system operator on one hand and the bulk network connection applicants and, or developer on the other hand:

Provided further that a fee per kVA supplied shall be paid by each bulk network connection applicant as HV contribution as stipulated in item 9 of the Sixth Schedule and payment is to be effected in accordance with item 21 of the Sixth Schedule.

Provided further that in such a case the distribution system operator shall retain the right to extend network connections from the said extension to third parties without making any additional payment or compensation to the applicant.

(9) In the case of a multiple customer development that requires a mix of one or more bulk network connections and one or more standard network connections, the total current requested for the multiple customer development is computed as the sum of the bulk network connections current required and the number of building units multiplied by the diversified load as set out in sub-regulation (7) evenly distributed on the three phase as applicable. The network connection for the multiple customer development shall be rated according to the total current calculated and then provided using the same criteria found in regulation 10.
