Cosoft N°: 83492336
Project Number: 14.2275.7-338.00
The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH is currently implementing the following Project: Transformational Energy Use for Sierra Leone – Phase 1” (TEUSL-1)
The “Transformational Energy Use for Sierra Leone – Phase 1” (TEUSL-1) is a multi-donor action jointly co-financed by the European Union and the German Federal Ministry for Economic Cooperation and Development, BMZ and implemented by GIZ as a contribution to the multi-donor initiative Energising Development (EnDev), which is also financed by the Netherlands Ministry of Foreign Affairs, the Norwegian Ministry of Foreign Affairs (NORAD), the German Federal Ministry for Economic Cooperation and Development, and the Swiss Agency for Development and Cooperation (SDC).
As part of this project, GIZ intends to award contract/s for the Supply and Installation of two (2) Hybrid roof top and ground mounted Solar PV Systems for World Food Programme (WFP)Agricultural rice milling hubs.
Exact explanation of the two sites
This contract will cover two (2) sites: Zimmi in Pujehun District (15.4 kWp) and Rokupr in Kambia District (18.7 kWp). Battery Energy Storage Systems (BESS) will be installed using a combination of Hybrid rooftop and ground-mounted structures. At Zimmi, the system will comprise ground-mounted galvanised steel or aluminium structures at a 15-degree tilt with 1.5 metres of clearance and a layout of two module strings, each containing 14 panels. At Rokupr, corrosion-resistant materials will be used for the rooftop and ground supports to ensure waterproofing and long-term structural stability. All structures will be oriented to maximise solar exposure and prevent shading.
The scope of task includes transporting PV system components (modules, inverters, batteries, mounting structures and cabling, to both sites, as well as manual offloading) safeguarding materials, removing waste and cleaning the site. Installation work will include internal wiring for lighting and sockets, setting up hybrid inverters and BESS in newly built secure rooms, and fully commissioning the systems. The exact Bill of Quantity (BoQ) will be provided to the applicants. The contractor will also provide technical documentation and conduct user training to ensure the systems are operated safely and efficiently.
The implementation will be at the location below:
• Zimmi, Pujehun District – 15.4Kwp
• Rokupr, Kambia District – 18.7Kwp
The scope of works in the four listed sites above requires the supply of BOQs materials and Installation of Hybrid Solar PV System for WFP Agric rice milling hub including but not limited to the following:
1) Supply of all necessary equipment and materials BOQ
2) Transportation of materials to the sites
3) Erection and installation of all electrical components PV modules, inverters and BESS
4) Integration of back up diesel generators
5) Conducting site acceptance tests
6) System commissioning
7) Provide introductional O&M training to facility users and their technicians.
