Despite great potential, geothermal deployment in developing countries has been below expectations since 2010. Geothermal energy has the potential to provide significant amounts of low-carbon electricity in many developing countries and is the cheapest source of available power in some developing countries.
The major barrier is securing early-stage project finance given the scarce public resources available to invest in exploration and development. While some countries are pursuing policies to liberalize energy and electricity markets to attract private investment, significant difficulties remain.
CPI analyzed three case studies on behalf of the Climate Investment Funds, with the aim of helping policymakers and development finance institutions understand which policy and financing tools to use in order to enable rapid and cost-effective deployment of geothermal for electricity.
Our case studies show that the increase in tariffs needed to provide sufficient returns to incentivize private investment can be entirely offset by public measures addressing specific risks. This graphic illustrates how these public risk mitigation measures (orange) combine to result in a final levelized cost of electricity for a privately developed project (dark grey) that is even lower than what it would have been for the state to develop it (light grey).
