Supply, Installation and Commissioning of Solar PV-Lithium Ion Batteries Hybrid System for and East , Tawi-Tawi

7 August 2019 Project funded by the European Union

1. Background Information UNIDO, in partnership with the Development Authority (MinDA), is implementing the Renewable Energy Technology to Increase Value-Added of Seaweeds in Tawi-Tawi (RETS) Project funded by the European Union, under the Philippine Department of Energy’s (DOE) Access to Sustainable Energy Programme (ASEP). The archipelagic province, Tawi-Tawi, is the southernmost frontier of the Philippines and belongs to the Autonomous Region in Muslim Mindanao (BARMM). Tawi-Tawi is the leading supplier of seaweeds throughout the country but is faced with problems such as declining production and annual value. Tawi-Tawi also remains among the poorest and least electrified provinces in the country. The bulk of seaweeds production comes from the island municipalities of Sitangkai, , , and Sibutu, that are each served by National Power Corporation – Small Power Utilities Group (NPC-SPUG) diesel generator units. However, household electrification rates on average is just about 20%. The project aims to increase and extend the availability of electricity service in these island municipalities that are home to about 15,000 seaweed farmers, through the renewable energy hybridization of the island grids in the municipalities of Sitangkai and Sibutu. The project integrates electrification with efforts to enhance the quality and increase the value of seaweeds produced by the seaweed farming communities as well as with the delivery of community social and welfare services, thus improving the quality of life. The project is being implemented in close coordination with local partners that include Tawi-Tawi Electric Cooperative Inc. (TAWELCO), Mindanao State University (MSU) Tawi-Tawi, Bureau of Fisheries and Aquatic Resources (BFAR)-ARMM, provincial local government of Tawi-Tawi (LGU) and the Association of Isolated Electric Cooperatives Missionary Green Energy Corp. (AIEC MGEC), working through its Joint Venture partnership with Island Light and Water Energy Development Corporation (ILAW). Integration of the energy aspect of the action with productive uses and income-generating activities will improve the households’ ability to pay for the energy service and thus contributes to the sustainability of the project.

2. Objectives of the Project This Terms of Reference is developed to identify a contracting partner for the Supply, Installation and Commissioning of Solar PV-Lithium Ion Batteries Hybrid Systems for Sitangkai and Sibutu, Tawi-Tawi Philippines. These activities are subdivided into two lots for each of the sites covered and will be implemented simultaneously. The Sitangkai renewable energy hybrid system will be composed of: (i) 1000 kWp Solar PV; (ii) 744 kWh Lithium Ion Energy Storage System; and (iii) 620 kW Diesel Generator The Sibutu renewable energy hybrid system will be composed of: (i) 646 kWp Solar PV; (ii) 587 kWh Lithium Ion Energy Storage System; (iii) and would have to be integrated with the existing NPC-SPUG Tandubanak Diesel Power Plant For both sites, the electricity produced by the system shall be fed into the existing small island isolated grid of the distribution utility, TAWELCO, in Sitangkai and eastern part of Sibutu. The general objective of the project is to provide reliable and cost-effective renewable energy hybrid systems that will be delivered as: (a) Compliant to standards on renewable energy and hybrid systems for rural electrification and all applicable and latest international/local codes and engineering design criteria and practices as required by existing laws and regulations; (b) A complete and fully operational facility with all equipment in working order and integrated with the local distribution grid and full commercial operation at the required generation output. This installation is a showcase set-up whereby aesthetic value and quality have to be aligned to the overall project objectives. The project shall serve as a model for other remote, un-electrified areas in the Philippines and a model for other electric cooperatives and private entities in the country to implement electrification projects integrated with productive uses, delivery of social welfare and water supply. The sustainability and replicability of the project will be given due consideration. This implementation exercise will provide the framework for linking energy supply programmes with operational programmes for agriculture and rural development and provide data for national level resource allocations and policy guidelines for the rural energy sector. Being implemented by UNIDO, the project is aligned with the Sustainable Development Goal (SDG) 7 to ensure access to affordable, reliable, sustainable and modern energy for all. Specific objectives of the project include: to increase access to modern energy services (number of households with improved electricity service; number of households with new connection; number of individuals served through social service facilities); increase the share of RE mix (% RE based on capacity and units of electricity produced in the island grids covered by the project); and provide reliability in availability of power (provide 24/7 service hours and reduction or elimination of power outages and disruptions) thus making the electricity service in the island suitable for household, institutional and commercial use. The project aims to contribute to the seaweed value chain development and integration with local socio-economic development plans and programs. The RE hybrid system will also reduce dependency on fossil fuels thus improving energy security. The output of the project should translate RFP No. 1100127849 | 2 to reduced volume of diesel use in Liters, savings on diesel in PhP/USD, reduced greenhouse gas emissions in tCO2eq and reduced energy costs.
