2008 Dominion 25
Our Brayton Point Power Station, New England’s largest fossil-fueled
power station, also defines our commitment to the environment and to the
conservation of natural resources. Brayton Point is putting into place emissions
and water usage controls that will benefit Massachusetts and Rhode Island.
We are building two cooling towers at Brayton Point scheduled to be op-
erational by 2012. They are designed to reduce the station’s thermal impact
on Mount Hope Bay and reduce cooling water use by more than 90 percent.
In addition, pollution-control equipment was installed for two coal-burning
units. This equipment is designed to reduce emissions of sulfur dioxide—
a cause of acid rain—by about 90 percent. A scrubber for a third coal unit
is expected to be in operation by 2014.
These expenditures bring overall investment in air and water environmen-
tal improvements at Brayton to more than $1 billion.
We also entered a long-term agreement with the Illinois Environmental
Protection Agency to further reduce sulfur dioxide and nitrogen oxides
emissions at our coal-fired, 1,158-megawatt Kincaid Power Station. This
demonstrates our belief that we can find solutions to issues by confronting
them in a constructive manner.
Cleaner Air in Virginia. In 2008 we began operating a new scrubber
at our Chesterfield Power Station in Central Virginia, continuing the state’s
move toward cleaner air. The equipment removes more than 95 percent of
sulfur dioxide emissions and more than 90 percent of mercury emissions from
the company’s largest coal-fired generating unit.
This scrubber is the latest, but not the last, chapter in Dominion’s long
history of environmental stewardship. Dominion is building another
scrubber to clean the emissions on the other three coal units at Chesterfield.
That scrubber is expected to be operational in 2011.
By 2015 Dominion is expected to have spent $2.25 billion on
environmental projects at power stations generating electricity for Virginia,
including $920 million at Chesterfield. Deep reductions are expected—
Our efforts to harness cleaner, greener power
through wind turbines forged ahead in 2008.
