Two technologies that were immature and expensive only a few years ago but are now at the center of the unfolding low-carbon energy transition have seen spectacular gains in cost-competitiveness in the last year. The latest analysis by research company BloombergNEF (BNEF) shows that the benchmark levelized cost of electricity, or LCOE, for lithium-ion batteries has fallen 35% to $187 per megawatt-hour since the first half of 2018. Meanwhile, the benchmark LCOE for offshore wind has tumbled by 24%. Onshore wind and photovoltaic solar have also gotten cheaper, their respective benchmark LCOE reaching $50 and $57 per megawatt-hour for projects starting construction in early 2019, down 10% and 18% on the equivalent figures of a year ago.
