Expanding access to electricity requires more than installing renewable energy systems. It starts with understanding where energy is needed most, designing solutions that respond to local realities, and creating projects that are technically sound, financially viable, and ready for investment.
To support Guinea’s rural electrification ambitions, the International Solar Alliance (ISA) commissioned an assessment of selected areas across the country to identify the most suitable locations for solar mini-grids and prepare bankable Detailed Project Reports (DPRs) for future implementation.
Through a partnership between Estudios Energéticos Consultores (EEC) and Engreen, the project combines technical expertise, field assessments, and strategic planning to transform energy opportunities into investment-ready renewable energy projects.
Why it matters
More than half of Guinea’s population still lacks access to reliable electricity, particularly in rural areas where extending the national grid is often technically complex and economically unfeasible.
Solar mini-grids offer a scalable and sustainable alternative. However, successful projects require much more than technology. They depend on accurate demand assessments, robust technical designs, appropriate business models, supportive regulatory frameworks, and the confidence of public and private investors.
By developing high-quality, bankable projects, the initiative helps reduce investment risks while accelerating the deployment of decentralized renewable energy solutions that can improve livelihoods, strengthen local economies, and increase climate resilience.
What the project does
The project provides a comprehensive assessment of Guinea’s solar mini-grid potential and develops the technical foundations for future investments.
Activities include:
- analysing Guinea’s energy sector, electricity demand, and renewable energy landscape;
- conducting detailed socio-economic and energy demand assessments in selected communities;
- evaluating renewable energy resources and identifying the most suitable locations for solar mini-grids;
- designing optimized mini-grid systems, including energy storage solutions and technical specifications;
- assessing financing mechanisms, business models, and the country’s investment ecosystem;
- reviewing national policies and regulatory frameworks to identify opportunities for scaling decentralized renewable energy;
- analysing existing mini-grid projects to capture lessons learned and best practices;
- preparing bankable Detailed Project Reports (DPRs) complete with engineering designs, financial analysis, implementation plans, environmental considerations, operation and maintenance strategies, and expected CO₂ emissions reductions.
Together, these activities create a portfolio of investment-ready projects capable of accelerating rural electrification across Guinea.
Expected Impact
The project establishes the technical and financial foundations needed to expand access to clean electricity in rural Guinea.
By transforming field assessments into bankable renewable energy projects, the initiative is expected to:
- accelerate the deployment of solar mini-grids in underserved communities;
- strengthen investor confidence through robust technical and financial documentation;
- support national electrification and renewable energy objectives;
- improve access to reliable electricity for households, businesses and public services;
- reduce greenhouse gas emissions by replacing fossil fuel-based energy generation;
- stimulate local economic development through productive uses of electricity.
Ultimately, the project demonstrates how rigorous planning can turn renewable energy potential into sustainable development opportunities.
Engreen’s Role
Together with GME, Engreen contributes to the technical development of the project, combining engineering expertise with field-based assessments to transform project concepts into investment-ready renewable energy solutions.
Engreen leads the assessment of selected sites, evaluates renewable energy resources, identifies optimal locations for solar mini-grids, sizes generation and battery storage systems, and prepares the technical components of the bankable Detailed Project Reports.
Our work also includes implementation planning, statutory compliance, operation and maintenance strategies, risk analysis, and the definition of technically robust and financially viable solutions that can support Guinea’s rural electrification objectives.
Consortium
