Ghana has decided to review its 2011 renewable energy act that set a target of 10% renewable energy in the power mix by 2020 and to postpone this target by 10 years to 2030. This new timeschedule is in line with the country's Nationally Determined Contribution (NDC). The NDC planned to scale up renewable penetration by 10% by 2030, by increasing small hydropower capacity to 150-300 MW, wind power capacity to 50-150 MW, and solar capacity to 10 MW (55 solar minigrids with an average capacity of 100 kW).
The country's power mix is dominated by thermal generation and hydropower generation. The share of hydropower has fallen since 2010, from 69% to 40% in 2017, to the advantage of gas (from 11% in 2010 to 54% in 2017). Ghana's power generation exceeds domestic consumption (14 TWh and 10 TWh, respectively, in 2017) and this excess capacity has discouraged investments in renewable power projects. The government is promoting solar power to ensure power supply in rural communities and to help achieve universal access to electricity.
