Fossil fuels blown away by wind in cost terms: study

AFP  |  Paris 

New onshore wind and solar projects are set to deliver more cheaply than fossil fuels plants, with other also rapidly gaining a cost advantage over dirty fuels, a report published today said.

According to a new cost analysis from the International Renewable Agency (IRENA), within two years "all the that are now in commercial use are expected to fall within the fossil fuel- fired cost range, with most at the lower end or undercutting fossil fuels".

It expects renewables will cost between three and 10 US cents per kilowatt hour (kWh) by 2020, while the current cost spectrum for power generation ranges from five to 17 US cents per kWh.

"This new dynamic signals a significant shift in the paradigm," said IRENA's Director-General, Adnan Amin, in a statement.

"Turning to renewables for new power generation is not simply an environmentally conscious decision, it is now -- overwhelmingly -- a smart economic one," he added.

Continued technological advancements are not the only factor helping drive down prices. The report found that the market was becoming more competitive and a number of experienced project developers had emerged in the sector.

The best onshore wind and solar PV projects are expected to deliver for three US cents or less by next year.

But onshore wind and solar are not the only sectors becoming more competitive rapidly. The study found that new bioenergy and geothermal projects commissioned in 2017 had global weighted average costs of around seven US cents per kWh.

IRENA said auction results suggest that two other technologies --concentrating solar power (CSP) and offshore wind -- will provide for between 6-10 US cents per kWh by 2020.

"These cost declines across technologies are unprecedented and of the degree to which renewable is disrupting the global system," said Amin.

The report was released on the first day of the eighth assembly of IRENA, which aims to be a global hub for renewable cooperation and information exchange by its 154 member countries.
