The ever-decreasing cost of electricity from batteries is giving fossil fuels a run for their money as renewable energy projects combined with battery storage become increasingly competitive power supply options. The LCOE for lithium-ion batteries has fallen 35% to $187/MWh since the first half of 2018, research company BNEF said Tuesday. Going back to 2012, BNEF found the cost of battery storage has dropped 76%, from almost $800/MWh.
