Project features

The World Bank is supporting the GoT in the development of a greenfield solar PV plant with energy storage. Implementation of the solar PV project with the initial estimated size of 200 MWac is part of the least-cost generation expansion plan set forth in the National Development Strategy 2030 (NDS-2030). Juru was selected as the Technical Consultant to carry out comparative analysis of 3 preselected project sites, perform a bankable Feasibility Study for the solar PV plant and grid interconnection, undertake high-level ESS assessment and oversee the preparatory works for the Project site. Juru will also prepare the technical specifications to be included in the IPP/PPP procurement documents and support the bidding process by providing technical advisory.
