For instance, during a Q4 earnings call last month, Jim Robo, CEO of NextEra Energy, predicted that by the early 2020s, it will be cheaper to build new renewables than to continue running
existing coal units.

That project would include the closure of DEP's
existing 379 MW Asheville 1 and 2
coal units and construction of about 752 MW of natural gas - fired generation (two 280 MW combined cycle
units proposed to commence operations in 2019 and an optional 192 MW combustion turbine
unit proposed to commence operations in 2023).
Gas - shift ERCs are produced by
existing NGCC
units that increase their output and displace
coal.
* For the comparison to
existing or new NGCC, UCS assumes that the NGCC
unit would run at the same capacity factor as the
coal unit under consideration.
The base running costs in $ / megawatt - hour (MWh) for each
coal unit are compared to several competitive energy resources:
existing natural gas combined - cycle (NGCC) plants, * new NGCC plants, new wind power facilities, and new utility - scale solar photovoltaic (PV) systems.
TXU also promised to cut emissions of pollutants including sulfur dioxide and nitrogen oxide and mercury by 20 percent, saying it would spend $ 500 million on equipment to control pollution at three of its
existing coal - fired
units in Texas.
Importantly, the UCS analysis represents a conservative estimate for the economic competitiveness of wind and solar resources, because it assumes that the new renewable resources would be built in the same geographic area as the
existing coal fired generating
units.
The figure below shows the climate impacts over time (measured in
units called radiative forcing) of
existing coal (the dashed black line), new high - efficient
coal plants (the solid black line), and new gas plants (the green line).
Ultra-supercritical
units are superior to the
existing fleet of traditional
coal - fired power plants that have a thermal efficiency of only 32 % HHV.
There is also no distinction made in the article between
coal plants by
unit age, LCOE or between new builds and
existing infrastructure.
On September 27, 2016, the entire United States District Court for the District of Columbia will hear oral arguments in West Virginia, et al. v EPA, to which E&E Legal is party, challenging the EPA's «Carbon Pollution Emission Guidelines for
Existing Stationary Sources: Electric Utility Generating
Units» rule under section 111 (d) of the Clean Air Act, over the Environmental Protection Agency's (EPA) regulation that will cripple, and in many cases, shut down
coal - fired power plants.
If no new
coal plants are built and each
existing unit is retired when it turns 40 years old, the 2 °C carbon budget will still be exhausted by 2040.
The authors have not provided their estimates of the cost of electricity from
existing coal or gas - fired
units.
The MATS rule requires that all U.S.
coal - and oil - fired power plants greater than 25 megawatts meet emission limits consistent with the average performance of the top 12 % of
existing units — known as the maximum achievable control technology (MACT).
The Environmental Protection Agency's (EPA) forthcoming climate change regulations for new and
existing electricity generating
units have been appropriately labeled the «war on
coal,» [1] because the proposed limits for carbon dioxide emissions would essentially prohibit the construction of new
coal - fired power plants and force
existing ones into early retirement.
