Unlocking Energy Access with Minigrids: Affordable, Reliable, Clean Power
Today, over 1.5 billion people, primarily in developing countries, lack access to dependable energy. Addressing this urgent issue requires immediate action to expand access to affordable and reliable clean electricity worldwide. A swift transition to sustainable energy, driven by targeted initiatives to combat energy poverty, has the potential to transform millions of lives while addressing climate change.
Renewable energy systems, including minigrids, stand-alone units, and off-grid solutions, play a crucial role in this effort. These systems can independently generate and distribute power, making them ideal for areas with limited or no connection to traditional grids. Research indicates that Distributed Renewable Energy (DRE) could provide electricity to about 500 million people by 2030. DRE systems not only replace environmentally harmful diesel generators but also improve energy affordability and reliability for homes and businesses. Additionally, their deployment and maintenance create high-quality local jobs. The International Energy Agency has identified off-grid solutions as the most cost-effective way to electrify nearly half the world’s unconnected population by 2030.
Minigrids and Microgrids: Key Solutions for Energy Access
Minigrids are small, independent power networks that can integrate with the main grid or operate autonomously. They supply power to various users, including homes, businesses, and industries, within a specific area, making them particularly useful in rural or semi-urban regions where extending the main grid is impractical or costly.
In contrast, microgrids are smaller-scale systems that typically serve a single location, such as a hospital, university, or military base. Both systems decentralize energy generation and provide reliable, affordable electricity to underserved areas, making them vital for achieving global energy access targets. However, despite their promise, the adoption of minigrids in developing countries has been slow due to various challenges.
Barriers to Minigrid Adoption
A report by BloombergNEF and SEforALL highlights three key obstacles: the need for regulatory frameworks to protect revenue streams, affordability concerns, and the scalability limitations of small projects. Additional challenges include:

A report by BloombergNEF and SEforALL highlights three key obstacles: the need for regulatory frameworks to protect revenue streams, affordability concerns, and the scalability limitations of small projects. Additional challenges include:
- High engineering and design costs for localized customization.
- Expensive technology and equipment, hindering widespread adoption.
- Limited access to affordable financing.
- Low purchasing power in target communities, impacting project sustainability.
- Weak community engagement and social engineering systems.
Overcoming these barriers requires comprehensive strategies to lower costs, improve financing options, and strengthen community involvement while ensuring affordability for local populations.
Drivers for Scaling Minigrids
The World Bank’s Energy Sector Management Assistance Program outlines five key drivers to unlock the full potential of minigrids:
Drivers for Scaling Minigrids
The World Bank’s Energy Sector Management Assistance Program outlines five key drivers to unlock the full potential of minigrids:
- Reducing the cost of solar-hybrid minigrid electricity to $0.20/kWh by 2030, enabling millions to access life-changing power for just $10 per month.
- Scaling deployment to 2,000 minigrids per country annually by focusing on project portfolios instead of individual projects.
- Providing reliable power to support 200,000 schools and clinics and meet the energy demands of three million income-generating appliances.
- Attracting private-sector financing through development partner funding and government investments, potentially raising $127 billion by 2030.
- Simplifying policies and regulations to minimize bureaucratic delays in low-access countries.
Innovative Payment Solutions
In India, the "Climate Smart Village Solution" pilot has enabled farmers to use solar power for irrigation and other needs, increasing income while reducing costs through inverter-less, battery-free solutions. Such initiatives demonstrate the potential of renewable energy to support rural economies affordably.
Achieving SDG 7 with Standardized Systems
To meet Sustainable Development Goal 7 (SDG 7), Africa alone will require 100,000 minigrids annually. Standardizing designs and products can simplify installation, reduce engineering complexities, and accelerate deployment. Solar projects in India, ranging from 50 kW to 3 MW, show promising outcomes, with payback periods of 3 to 3.5 years and lifetime savings of 8 to 10 times the initial investment.
Transforming Lives with Minigrids
Minigrids provide life-changing power in underserved areas. For example, a solar-powered 8.7 kW minigrid installed at a maternity hospital in Kisii, Kenya, enabled 24/7 operations, increasing monthly deliveries from 5 to 20 and reducing energy costs. On Myanmar’s Kenti Island, a solar minigrid now powers 300 households, schools, a clinic, and businesses, spurring local economic growth and empowering women to start home-based ventures.
Benefits of Standardization
Standardized minigrid systems offer several advantages:
