REQUEST FOR EXPRESSION OF INTEREST (EOI)
SUPPLY OF BOQ MATERIALS AND INSTALLATION OF STANDALONE PV AND BATTERY STORAGE SYSTEMS TO SUPPORT SIERRA LEONE’S ECO-TOURISM SECTOR
Cosoft N°: 83497698
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 ten (10) Hybrid standalone Solar PV System to electrify the Sierra Leone eco-tourism sectors of Tiwai island, Banana Island and Tacugama chimpanzee sanctuary and it reserves support schools and charging stations. For Tacugama, the system will include the supply and installation of two 200-liter solar water heaters, and a 4-meter-high steel structure for the water tanks.
Site and required works
The project will cover three primary locations and seven smaller sites, including systems of various capacities. Specifically, each of the three main sites—Tiwai Island in Pujehun District, Banana Island in the Western Area Rural, and Tacugama Chimpanzee Sanctuary in Freetown—will have a 5 kWp PV system. The systems will include battery storage of 20 kWh at Tiwai Island and Banana Island, and 15 kWh at Tacugama. Additionally, seven sites supported by systems of 1.2 kWp/4.8 kWh will serve schools and charging stations in Konombaya and Masonia in Loma Mountain Community in Pujehun District, and Fintonia in Autumba Kilim near Kamakwie.
The scope of work includes transporting all PV system components (modules, inverters, batteries, mounting structures, and cabling) to each site, manual offloading, safeguarding materials, removing waste, and cleaning the sites. Installation work will include internal wiring for lighting and sockets, setting up hybrid inverters, and Battery Energy Storage Systems (BESS). The installation at Tacugama will also include the installation of two 200-liter solar water heaters and a 4-meter-high steel structure for the water tanks. The exact Bill of Quantities (BoQ) will be provided to the applicants. The contractor will also supply technical documentation and conduct user training to ensure the systems are operated safely and efficiently.
The project will cover the following sites:
• Tiwai Island (Pujehun District): 5 kWp PV rooftop / 20 kWh battery storage system
• Banana Island (Western Area Rural): 5 kWp PV rooftop / 20 kWh battery storage system
• Tacugama Chimpanzee Sanctuary (Freetown): 5 kWp PVrooftop / 15 kWh battery storage system and installation of 2 units of 200 liters of solar water heater (including 4m elevated steel structure for the water tanks)
• Three (3)Tacugama-Supported Schools (Konombaya and Masonia in Loma Mountain, Pujehun District and Fintonia in Autumba kilim near Kamakwie): Each 1.2 kWp PV rooftop / 4.8 kWh battery storage system
