What Is BACT for CO2?
Assume, for the moment, that the U.S. Congress is unable to agree on legislation aimed at reducing carbon emissions from industry, vehicles, and power plants (the carrot approach). Further, assume that the Environmental Protection Agency (EPA) eventually promulgates rules that require power plants to reduce carbon emissions (the stick approach). Have you given any thought to the range of possible best available control technologies (BACT) that the EPA might require under the Clean Air Act (CAA)?

Rebuilding Feedwater Heaters While a Plant Is Online
Rebuilding aged feedwater heaters can make better economic sense than buying new ones, because rebuilding reduces capital cost and plant outage expenses. At one Texas generating station, rebuilding saved one-third the cost of a new feedwater heater while improving the plant’s heat rate.

Top Plants: Edison Sault Hydroelectric Plant Sault Ste. Marie, Michigan
Located on the border with Canada and operational since 1902, the Edison Sault Hydroelectric Plant is one of the oldest continuously operating power plants in North America. This pioneer plant continues to generate between 25 to 30 MW when operating at full capacity. Modern wind and solar projects have captured the public’s interest, but this century-old hydroelectric project shows that time is the ultimate arbiter of a technology’s value to society.

Top Plants: El Dorado Energy’s Solar Facility, Boulder City, Nevada
Sempra Generation has conjured up a market plan for producing merchant photovoltaic (PV) power that is inspired. Working with First Solar, Sempra has developed a finely tuned and standardized 1-MW PV power block that can be replicated as needed. Sempra built the modular PV plant on land adjacent to an existing gas-fired plant to shorten the development period, piggyback the power directly to the grid, and enable existing staff to manage the combined plants’ operation.
