Onshore wind power now as affordable as any other source, solar to halve by 2020

ABU DHABI. KAZINFORM - The cost of generating power from onshore wind has fallen by around a quarter since 2010, with solar photovoltaic, PV, electricity costs falling by 73 percent in that time, according to new cost analysis from the International Renewable Energy Agency, IRENA.

The report also highlights that solar PV costs are expected to halve by 2020. The best onshore wind and solar PV projects could be delivering electricity for an equivalent of US$3 cents per kilowatt hour, kWh, or less within the next two years, WAM reports.

Global weighted average costs over the last 12 months for onshore wind and solar PV now stand at 6 cents and 10 cents per kWh respectively, with recent auction results suggesting future projects will significantly undercut these averages. The report emphasises that onshore wind is now routinely commissioned for 4 cents per kWh. The current cost spectrum for fossil fuel power generation ranges from 5 to 17 cents per kWh.

"This new dynamic signals a significant shift in the energy paradigm. These cost declines across technologies are unprecedented and representative of the degree to which renewable energy is disrupting the global energy system," said Adnan Z. Amin, Director-General of IRENA.

Released on the first day of IRENA's Eighth Assembly in Abu Dhabi, "Renewable Power Generation Costs in 2017" underlines that other forms of renewable power generation, such as bioenergy, geothermal and hydropower projects in the last 12 months have competed head-to-head on costs, with power from fossil fuels. The findings note that by 2019, the best onshore wind and solar PV projects will be delivering electricity for 3 cents per kWh, significantly below the current cost of power from fossil fuels.

Competitive procurement practices together with the emergence of a large base of experienced medium-to-large project developers competing for global market opportunities are cited as new drivers of recent cost reductions, in addition to continued technology advancements.

"Turning to renewables for new power generation is not simply an environmentally conscious decision, it is now overwhelmingly a smart economic one. Governments around the world are recognising this potential and forging ahead with low-carbon economic agendas underpinned by renewables-based energy systems. We expect the transition to gather further momentum, supporting jobs, growth, improved health, national resilience and climate mitigation around the world in 2018 and beyond," said Amin.

The report also stresses that auction results are signalling that offshore wind and concentrating solar power projects commissioned in the period between 2020-22 will cost in the range of 6-10 cents per kWh, supporting accelerated deployment globally. IRENA projects that all renewable energy technologies will compete with fossils on price by 2020.

The report highlights that the global weighted average levelised cost of electricity, LCOE, of utility-scale solar PV has fallen by 73 percent between 2010 and 2017 to 10 cents/kWh.

The average cost of electricity from onshore wind fell by 23 percent between 2010 and 2017. Projects are now routinely commissioned at 4 cents/kWh and the global weighted average is around 6 cents/kWh. By 2019, the best onshore wind and solar PV projects will be delivering electricity for an equivalent of 3 cents/kWh, or less.

New bio-energy and geothermal projects commissioned in 2017 had global weighted average costs of around 7 cents/kWh.

Record low prices for solar PV in Abu Dhabi, Chile, Dubai, Mexico, Peru and Saudi Arabia have made 3 cents kWh and below the new benchmark. By 2020, project and auction data suggest that all currently commercialised renewable power generation technologies will be competing, and even undercutting, fossil fuels by generating in the range of 3 to 10 cents/kWh.
