Energy Storage Container still dominates renewable energy capacity additions

Solar PV’s installed power capacity is poised to surpass that of coal by 2027, becoming the largest in the world. Cumulative solar PV capacity almost triples in our forecast, growing by almost 1 500 GW over the period, exceeding natural gas by 2026 and coal by 2027. Annual solar PV capacity additions increase every year for the next five years.

Despite current higher investment costs due to elevated commodity prices, utility-scale solar PV is the least costly option for new electricity generation in a significant majority of countries worldwide. Distributed solar PV, such as rooftop solar on buildings, is also set for faster growth as a result of higher retail electricity prices and growing policy support to help consumers save money on their energy bills.

Renewable capacity expansion in the next five years will be much faster than what was expected just a year ago. Over 2022-2027, renewables are seen growing by almost 2 400 GW in our main forecast, equal to the entire installed power capacity of China today. That’s an 85% acceleration from the previous five years, and almost 30% higher than what was forecast in last year’s report, making it our largest ever upward revision. Renewables are set to account for over 90% of global electricity capacity expansion over the forecast period. The upward revision is mainly driven by China, the European Union, the United States and India, which are all implementing existing policies and regulatory and market reforms, while also introducing new ones more quickly than expected in reaction to the energy crisis. China’s 14th Five-Year Plan and market reforms, the REPowerEU plan and the US Inflation Reduction Act are the main drivers of the revised forecasts.

Renewables become the largest source of global electricity generation by early 2025, surpassing coal. Their share of the power mix is forecast to increase by 10 percentage points over the forecast period, reaching 38% in 2027. Renewables are the only electricity generation source whose share is expected to grow, with declining shares for coal, natural gas, nuclear and oil generation. Electricity from wind and solar PV more than doubles in the next five years, providing almost 20% of global power generation in 2027. These variable technologies account for 80% of global renewable generation increase over the forecast period, which will require additional sources of power system flexibility. Meanwhile, the growth of dispatchable renewables including hydropower, bioenergy, geothermal and concentrated solar power remains limited despite their critical role in integrating wind and solar PV into global electricity systems.
