Where are you getting this claim? Natural gas costs somewhere between $40 and $70 per MWh [1]. Storage costs for batteries range from $100/KWh (very optimistic) to $300/KWh [2]. But that's per kilowatt hours. That's $100,000 per MWh to $300,000 per MWh.
Solar and wind's dispatchability remains its key weakness. Storage at anywhere near the required amounts remains a fantasy. That's why Germany and California are still burning fossil fuels for ~40% of their energy, while France's share of fossil fuel generation is under 10%.
