Feasibility Study for 150 MWp Solar PV + 650 MWh BESS Project

  • Client: eSunScope Solar Private Limited
  • Project Location: Democratic Republic of the Congo (Central Africa)

Project Overview

QQ Engineering & Consulting (QQEC) was engaged to provide feasibility and engineering consulting services for a utility-scale 150 MWp Solar PV plant integrated with a 650 MWh Battery Energy Storage System (BESS) in the Democratic Republic of the Congo (Central Africa).

The objective of the project was to evaluate the technical, and financial feasibility of developing a reliable Solar PV + BESS solution capable of supporting long-term renewable energy deployment and RTC (Round-The-Clock) power applications in the region.

QQEC carried out a comprehensive assessment covering site suitability, hydrology and flood risk analysis, solar resource evaluation, energy yield modelling, battery sizing, system optimization, and techno-commercial analysis. Multiple PV-BESS configurations were analyzed to identify optimized solutions balancing energy performance, storage reliability, and overall project economics.

Despite challenging project conditions and aggressive timelines, QQEC successfully delivered structured and high-quality technical outputs to support project planning, investment evaluation, and future execution strategy.
