THE PROJECT INFORMATION 2.1 BRIEF DESCRIPTION OF THE PROJECT
The Projects comprise, installation of Prepayment active energy meters on existing and new service lines, modification of existing metering installations and service lines and their associated switchgears and accessories on low voltage networks using materials supplied by KPLC. 1. KPLC will install 25,000 meters in Nairobi from June 2009 to August 2009; and
KPLC expects to connect a further 250,000 prepayment meters over the next two years.
2. Jobs shall be allocated on piece rate basis as and when required to multiple contractors.
3. The contracts shall be valid for 2years. The various installations we have include:
a) Installation of Prepayment active energy meters. b) Installation and modification of new and existing meter-boards. c) Modification of existing Service lines, sub-mains and their associated
accessories. d) Installation of the communication cable e) Installation of the consumer interface unit (CIU)
A brief indication of the various installations involved is as follows: 2.2 ITEM DESCRIPTION 2.2.1 INSTALLATION OF PREPAYMENT METERS. The Prepayment active energy meter shall basically be installed on low voltage lines (240-415v). They shall be installed on new and existing supply points. In case of new installations, a suitable meter board and its associated accessories shall be installed to suite the metering equipment and shall be mounted either on the customers premises or on the pole. The meter shall be made inaccessible to the customer by means of spot/arc welding. Where the installation is existing, the meter board shall be modified/replaced to accommodate the new metering equipment as above. The existing arrangement within the metering panel will have to be re-arranged such that the meters will be installed on the upper compartment of the panel while all the customers main switches will be installed on the lower compartment. This will give the customers free access to their main switches while the KPLC meters will be out of their reach. The re-arrangement should be carried out with outmost care to avoid cases of cross-wiring/metering at the mains switches. The diferrent scenarios ars as shown below:

2.2.2 INSTALLATION AND MODIFICATION OF EXISTING METER BOARDS The contractor shall be required to arrange/rearrange the wiring and the associated accessories to accommodate the new metering equipment as stated 2.2.1 above. At the same time recovery of the old metering equipment shall be done and send back to the identified KPLC stores. Pole mounted meter boards shall be mounted to give a nominal clearance from the ground and the live parts of the service line i.e. at least 25 feet above ground level in case of a 32 feet pole and a clearance of 3 feet from the live part of the service line. 2.2.3 MODIFICATION OF THE EXISTING SERVICE LINE. The existing service lines, sub mains and their accessories shall be modified to suite the new metering equipments as stated in 2.2.1 above
The proposed installation of the Prepayment meters.
The installation of Prepayment active energy meters shall be spread all over the Country.
