After stalling last year, global capacity additions of renewable power are set to bounce back with double-digit growth in 2019, driven by solar PV’s strong performance, according to the International Energy Agency. The IEA expects renewable capacity additions to grow by almost 12% this year, the fastest pace since 2015, to reach almost 200 GW, mostly thanks to solar PV and wind. Global solar PV additions are expected to increase by over 17%.
Renewables have a major part to play in curbing global emissions and providing universal access to affordable, secure, sustainable and modern energy. Renewable capacity additions need to grow by more than 300 GW on average each year between 2018 and 2030 to reach the goals of the Paris Agreement, according to the IEA’s Sustainable Development Scenario.
The cost of solar PV has plunged more than 80% since 2010, making the technology increasingly competitive in many countries. The IEA estimates that global solar PV capacity additions will increase to almost 115 GW this year, despite a slight decline in China, the world’s largest market. This is set to be the first year that solar PV additions have surpassed 100 GW and the third year in a row that they account for more than half of global renewable additions.
The pace of acceleration in the Chinese solar PV market remains the biggest uncertainty for the IEA’s 2019 estimates. China’s policy transition from feed-in tariffs to competitive auctions resulted in relatively slow solar PV deployment in the first half of 2019. But installations in the second half of the year are expected to accelerate with the completion of the first projects linked to large-scale auctions and the emergence of projects that rely far less on incentives to compete with other power sources.
