A few days ago, Bloomberg New Energy Finance stated that increasingly cheaper wind, solar and battery technologies are posing an unprecedented challenge to the three major roles of fossil fuel power generation: providing large amounts of electricity, dispatchable power generation and flexibility.
According to BNEF's latest report on levelized cost of electricity (LCOE), the global land-based wind levelization cost of electricity in the first half of 2018 was US$55/MWh, a decrease of 18% from the first half of 2017. Untraceable solar PV The levelization of electricity costs has also dropped by 18% to reach US$70/MWh. Offshore wind power leveling costs have fallen by 5% to US$118/MWh.
At the same time, BNEF’s lithium-ion battery price index fell from US$1,000/kWh in 2010 to US$209/kWh in 2017.
'As the penetration of wind and solar energy increases, some of the existing coal and natural gas power stations with huge investment will continue to play a role in achieving a combination of large generations of electricity and grid balance.' BNEF director of energy economics Elena Giannakopoulou said, 'But due to the battery Began to erode the flexibility and peak income of fossil-fuel power plants, so the economic case for building new coal and gas production capacity is collapsing.
According to BNEF, the onshore wind power levels in India, Brazil, Sweden and Australia are particularly low. In Chile, India, Australia and Jordan, the level of photovoltaic power generation is very low.
In India, for example, the levelized electricity costs of onshore wind power and photovoltaic power stations were US$39/MWh and US$41/MWh, respectively, a decrease of 46% and 45% year-on-year, respectively. The cost of coal is US$68/megaton. At watt hours, the cost of combined cycle natural gas is 93 US$/MWh. BNEF said that the cost of wind or solar plus batteries is very wide, but the median value is falling rapidly. For India's wind power plus batteries, the cost The range is $34-208/MWh, while the cost of solar plus batteries is $47-308/MWh.
