Cosoft N°: 83497697
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 a contract for the supply and installation of four (4) standalone Solar PV Hybrid Systems with Battery Energy Storage (BESS) to power four (4) agricultural processing centres consisting of two (2) x Vegetable processing centres and two (2) x Cocoa processing centres.
Site and required works
The design and assessment of the energy demands for these facilities has been completed. Each system will consist of a 13 kWp roof-mounted PV system and a 19 kWh Battery Energy Storage System (BESS).
The scope of tasks includes the supply and transport of all system components (modules, inverters, batteries, mounting structures, and cabling) to the sites; installation; testing; commissioning; and training of users. Installation works will include internal wiring for lighting, sockets and the existing agricultural processing machinery, setting up hybrid inverters and BESS in existing rooms, and fully commissioning the systems. The contractor will also provide technical documentation and conduct user training to ensure the systems are operated safely and efficiently.
The project will cover the following sites:
• Mamudiakoro community vegetable processing Centre in Wara Wara Yagala chiefdom (GPS: 9.631821,-11.525592)
• Koromasilaia vegetable processing Centre in DemballiaMusaia Chiefdom in Falaba district (GPS: 9.662258,-11.564660)
• Gbeika cacao processing Centre in Jahn Chiefdom in Kailahun District (GPS: 8.24985° N, –11.20957° W)
• Manjama cacao processing Centre in Soa Chiefdom, Kono District (GPS: 8.60274° N, –10.69654° W)
The scope of works at the site mentioned above requires the supply of BOQs materials and Installation of a roof top Solar PV system for the Vegetable & Cacao Centres 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 existing back up diesel generator
5) Conducting site acceptance tests
6) System commissioning
7) Provision of O&M training to facility users and their technicians.
The exact Bill of Quantity (BoQ) will be provided after evaluation of the EOI to all shortlisted applicants.
