Expression of Interest: Installation of PV Microgrid system in Central Sumba – MENTARI (Menuju Transisi Energi Rendah Karbon)

MENTARI (Menuju Transisi Energi Rendah Karbon) is a four-year programme that formally started on 6th January 2020. The programme aims to deliver inclusive economic growth and poverty reduction in Indonesia, by supporting the uptake of low carbon energy, to best support disadvantaged communities, particularly in eastern Indonesia.

Led by the British Embassy Jakarta, MENTARI is implemented by Palladium International Indonesia in consortium with Castlerock Consulting and Hivos. The programme has a specific focus on developing the low carbon energy sector to best support the disadvantaged communities, and specifically those in eastern Indonesia. By working closely with the Government of Indonesia and other stakeholders to improve the enabling environment and drive investment, MENTARI will demonstrate the possibilities of low carbon energy for Indonesia's economic development, job creation and social inclusion, while helping to mitigate climate and environmental impacts.

Renewable energy-based grids, such as centralized photovoltaic systems, are widely considered the best solutions for rural electrification. They provide a clean and sustainable answer for Indonesia’s geographical challenges, costly grid extensions, and expensive diesel-powered electrification programmes. The Ministry of Energy and Mineral Resources (MEMR) through the Directorate General of New, Renewable Energy and Energy Conservation (DGNREEC) plays a prominent role in increasing electricity access in remote locations, small islands, and border areas. Since 2011, DGNREEC has commissioned over one thousand hydropower and PV mini grids. This larger number excludes from partnerships with international donors. However, attracting private investment into the rural electrification in Indonesia remains a challenge.

Through our Demonstration Projects strand, MENTARI will showcase a replicable low carbon energy business model that can generate inclusive economic growth benefits. The demonstration project will be in Sumba and will use off-grid technology. MENTARI, on behalf of The Foreign, Commonwealth & Development Office (FCDO) is seeking tenders from providers to supply and install off-grid PV system in an unelectrified community in Mata Redi and Mata Woga villages in Central Sumba.

MENTARI invites experienced Engineering, Procurement, and Construction (EPC) companies to submit an Expression of Interest (EOI) and Prequalification responses for the installation tender of two interconnected photovoltaic microgrids: a 60 kWp system in Mata Redi and 35 kWp in Mata Woga villages in Central Sumba, East Nusa Tenggara. The successful EPC will be contracted under Palladium.

Your Expression of Interest (EoI) can be submitted via email to no later than midnight 30 April 2021, 00:00 (GMT+7).

A clarification round for questions or inquiries is open from 01 – 07 April 2021. Please send any inquiries or clarifications you have via email to with a mandatory subject of email: EOI/MENTARI/001/2021. A clarification response will be shared with interested supplier and published on Palladium website on 09 April 2021.

Companies will be selected in accordance with the procedure set out in the Palladium Procurement Guidelines. EOI received after the above deadline and failing to provide the requested information will not be considered.

This EOI is a pre-qualification; however, it does not entail any commitment on the part of Palladium, either financial or otherwise. Palladium reserves the right to accept or reject any or all EOI without incurring any obligation to inform the affected applicant/s of the grounds.
