Renewables increasingly beat even cheapest coal competitors on cost

Accordingly with the new IRENA (Renewable Energy Agency) report renewable power is increasingly cheaper than any new electricity capacity based on fossil fuels. Renewable Power Generation Costs in 2019 shows that more than half of the renewable capacity added in 2019 achieved lower power costs than the cheapest new coal plants.

The report highlights that new renewable power generation projects now increasingly undercut existing coal-fired plants. On average, new solar photovoltaic (PV) and onshore wind power cost less than keeping many existing coal plants in operation, and auction results show this trend accelerating – reinforcing the case to phase-out coal entirely. Next year, up to 1,200 gigawatts (GW) of existing coal capacity could cost more to operate than the cost of new utility-scale solar PV, the report shows.

Replacing the costliest 500 GW of coal with solar PV and onshore wind next year would cut power system costs by up to USD 23 billion every year and reduce annual emissions by around 1.8 gigatons (Gt) of carbon dioxide (CO2), equivalent to 5% of total global CO2emissions in 2019. It would also yield an investment stimulus of USD 940 billion, which is equal to around 1% of global GDP.
