This is how coal dies — super cheap renewables plus battery storage

New Colorado wind farms with batteries are now cheaper than running old coal plants

Solar, wind, and battery prices are dropping so fast that, in Colorado, building new renewable power plus battery storage is now cheaper than running old coal plants. This increasingly renders existing coal plants obsolete.

Two weeks ago, Xcel Energy quietly reported dozens of shockingly low bids it had received for building new solar and wind farms, many with battery storage (see table below). The median bid price in 2017 for wind plus battery storage was $21 per megawatt-hour, which is 2.1 cents per kilowatt-hour. As Carbon Tracker noted, this “appears to be lower than the operating cost of all coal plants currently in Colorado.”

The median bid price for solar plus battery storage was $36/MWh (3.6 cents/kwh), which may be lower than about three-fourths of operating coal capacity. For context, the average U.S. residential price for electricity is 12 cents/kWh.

Note that by definition, half of the bids are below the median price — and there were 87 bids for solar plus storage, meaning many bids were quite low (see table above). There were 96 bids for wind power alone — at a median price of 1.8 cents/kwh — which means some were very low-priced indeed. The tremendous number of bids in Colorado reveal the power of competition in driving prices down.
