Short Answer

Grants are funds provided with no expectation of repayment. Concessional loans, or soft loans, have more generous terms than market loans. These generally include below-market interest rates, grace periods in which the loan recipient is not required to make debt payments for several years or a combination of low interest rates/grace periods.

The availability of free or cheap capital in the form of a grant or concessional loan can be a huge boon to mini-grid project developers facing financing challenges. While there are several sources of grants and concessional financing, the funds are limited, and competition can be considerable. Some limit or restrict the countries in which they can be used, or they require a portion of funds be spent on equipment or services from donor countries. Grants sometimes have significant reporting and other administrative requirements, which cost money in the form of added staff time and transactional costs.

Putting it Into Practice

Researching Grants and the Grant Application Process

A successful grant application requires a good match between donor and applicant, a compelling case for funding (including rigorous metrics for judging project success) and a strong team with a credible track record.

Many funding entities request a short (one- or two-page) introductory letter as part of an initial screening process before they invite applicants to submit a full grant application. Project developers will need to research which grants are available, the focus of each grant-giving organization and their potential interest in the project, information about previous awardees that have managed similar projects, the grant cycle and the application process. Following are key questions to consider:

  • What grants are available?
  • How much time is required to complete the application process?
  • If the grant is accepted, will the timing of funds match project needs?
  • What are the reporting requirements?
  • What limitations are placed on the use of grant funds, and are they workable?
  • How robust is the competition likely to be?
  • How crucial is the grant to project development?

Swedish International Development Agency (SIDA)

SIDA is an agency of the Swedish Ministry for Foreign Affairs, responsible for development assistance to developing countries.

SIDA offers financing via development loans and guarantees (loan aid). Development loans consist of a donation from SIDA and a market-rate loan from a commercial lender. Development loans can be combined with a guarantee issued by SIDA to the lender for the borrower’s obligations.


USAID has played a leading role in supporting mini-grid infrastructure worldwide, primarily through its Global Development Alliances (GDAs) and Development Credit Authority (DCA).

GDAs are public-private partnerships catalyzed by USAID, pairing private sector businesses with development needs—a real market approach.

DCA provides risk-sharing agreements to help finance opportunities the private sector won’t finance. DCA has been instrumental in successfully mitigating risk so private capital can work in developing countries.

U.S. Millennium Challenge Corporation (MCC)

The MCC is a bilateral U.S. foreign-aid agency that focuses on promoting economic growth in recipient countries.

Some eligible countries have chosen to invest in power infrastructure. For example, the MCC’s Green Prosperity Facility in Indonesia is offering $30 million in grants for off-grid community-owned renewable energy projects. Other countries may have similar grant programs in the pipeline.

U.S. Trade Development Association (USTDA)
