Use international guarantees to cut the high interest rates that renewable energy projects in developing countries pay
In short
- Public money from rich countries covers the currency losses of renewable energy projects in developing countries.
- An international fund guarantees repayment when risks the project operators cannot prevent leave loans unpaid.
- This ends the upside-down unfairness in which the same power plant costs more in poorer countries.
- Coal, oil, and gas power plants cannot use this guarantee.
If this comes true
In a garment workshop in a landlocked country, cheap electricity now arrives from a nearby solar plant, so the sewing machines no longer stop during evening blackouts and the workers can accept big orders instead of turning them down.
Perhaps
Losses may pile up in projects protected by the guarantee, and the taxes of people in distant rich countries might be used to cover the hole.

The proposal in detail
This proposal covers projects in low-income and middle-income countries that build power plants such as solar and wind, along with the power grids that connect them. The ones who carry it out are an international guarantee fund that rich countries build by pooling their money, and each country's public development banks. The fund takes on two risks. The first is currency risk. A project usually borrows money in a foreign currency but receives its electricity payments in its own country's currency, so if the home currency falls, repayment suddenly becomes much heavier. The fund covers this gap up to a set limit, so that project operators can borrow in their own currency. The second is risk that operators cannot prevent, such as a sudden change in government policy or a failure to pay for the electricity the project sells. When the fund guarantees part of the repayment, private banks can lend at low interest rates. To receive the guarantee, a project must regularly report on how much power it generates, how construction is going, and how well it has explained the project to local residents, and it must accept outside inspections. Fossil fuel power plants are excluded. Losses caused by an operator's own bad management are not guaranteed, and the lending bank and the operator bear them. When the fund's losses grow, the countries that put money in share the burden according to their share of the investment, and the guarantee fees are reviewed.
BenefitsCountries rich in sun and wind can finally make cheap electricity
Much of the cost of a renewable power plant is the interest on borrowed money, so when interest rates fall, the price of electricity from the same plant falls right along with them. When the fund takes on currency risk, operators can borrow in their own currency, and repayment no longer balloons when the currency falls. Banks can then lend with confidence, and private money flows even into countries that were long seen as risky. Public money does not pay for everything but only covers part of the risk, so the same amount can support more power plants. When cheap electricity arrives, factories, hospitals, and schools are no longer at the mercy of blackouts, and they are freed from the fuel costs and exhaust of diesel generators. Countries whose electricity use is about to grow a great deal can also choose, from the start, a path that does not depend on fossil fuels, which helps cut the world's emissions well into the future. By excluding fossil fuels from the guarantee, the balance of gains and losses in choosing which to build tilts clearly toward renewables.
DrawbacksTaxpayers in distant countries will carry the guarantee's losses
A guarantee is a system in which money goes out only when things go wrong. If a big currency crash and political upheaval pile up together, the fund's losses can swell all at once, and the taxpayers of the countries that put in money will be the ones to fill the gap. When life is hard in their own country, many people will not accept paying for the losses of a project far away. Also, feeling protected, operators and banks may take on projects with sloppy plans. Even if the rule says management failures are not guaranteed, the line between a risk that could not be prevented and a failure is blurry in practice. The countries receiving the guarantee also pay a price. The conditions for outside inspections and reports can become a way for outside countries to meddle in a nation's electricity policy. Money may also gather around big projects that qualify for guarantees easily, while work that takes more effort, such as small village-level power generation, may be pushed aside. Taking on risk is not a pretty phrase; it means being ready to actually pay for losses.
Learn the background
Solar and wind power use almost no fuel, but they cost a great deal of money at the start. So the price of the electricity depends heavily on how cheaply the money can be borrowed. A project that can borrow at a low interest rate in a rich country may be asked for several times that rate in a low-income country, because of worries about the currency falling and about political change. Countries with the most sun and wind tend to be poorer, and they cannot build power plants, which is an upside-down situation. The people who suffer are those who live in areas with no electricity or frequent blackouts, and those who want to start businesses there. International support has been talked about for a long time, but public money from rich countries tends to avoid any project that might lose even a little, and private money does not flow into countries with high risk. Promises of support have piled up while nobody takes on the risk, and as a result, fossil fuel power plants, which are cheaper up front and have well-established ways to borrow, have kept being chosen. What is missing is not technology but a decision about where the risk should sit.
