Combining solar + battery energy storage reduces LCOE ~6%

 In Daily Hot Topics - Power

NREL released inaugural solar + battery energy storage report which indirectly says;

  • Standalone solar $60 MWh levelized cost of electricity (LCOE)
  • Standalone battery energy storage (BES) $171 MWh LCOE
  • Combined solar $56 MWh LCOE + BES $163 MWh LCOE

The takeaway is combining solar + BES reduces costs through shared indirect costs plus balance of plant, reducing solar LCOE -6% and BES LCOE -5%.
